CompTIA A+ Exam Study Guide

we're going to get into it right away we can't waste any time this quiz is going to be almost 100 questions I think it's about 95 questions so it's going to be a long video Let's Get It Started I'll explain along the way which of the following types of devices most often and you got to pay attention to this in the actual exam most often uses a thunderbolt cable CU some of them might be two different answers but which one is the most often Linux PC Android mobile Apple laptop or the Chromebook I'll give you guys a couple seconds to figure it out correct answer is the Apple laptop we could use this little button down here to narrow down our results user reports limited or no connectivity on a laptop a technician runs ip config all with the following result ipv4 connectivity limited or none ipv4 address 169 254 2541 subnet mask 255 25500 which of the following is the most likely cause of this issue DHCP failure ARP cache DNS resolution or duplicate IP address correct answer DHCP failure which of the following is an unsecure remote access protocol s SSH https SFTP or telet one of the things that I want to mention for this one is if you're not sure if they have abbreviations uh number one we have an abbreviation uh video so you can go take a look at that if you're not familiar with some of them number two is if you're not sure what some of the abbreviations stand for on the test you can always come back to some questions later and figure out what they what they mean if you forgot and then come back to the answer and you might get some more clarity so uh which of the following unsecure remote access protocol this one should be telnet and it is telnet which of the following cable types is the standard connector on printers DVI eeta USB or lightning correct answer should be USB uh which of the following is the maximum power Poe plus provides so Poe is power over ethernet plus uh 15.4 Watts 30 Watts 60 watts or 95 Watts correct [Music] answer is B 30 Watts uh user reports the touchcreen on Android smartphone is not responding to any input the technician has cleared the cache restarted the phone and ensured the phone is fully charged the issue still persists which of the following should the technician replace on the phone to most likely resolve the issue system on a chip accelerometer digitizer or gyroscope correct answer is the digitizer and by the way this is not just for screens I know in the exams they should really mostly talk about this in reference to screens but this is not always screens uh which of the following is the safest way to replace it's basically just transfers uh analog signal to Digital Signal uh which of the following is the safest way to replace RAM on a server that has a redundant power supply unplug one power cable verify the ram temperature utilize a verify the ram temperature utilize a grounding strap or replace the ram while the server is running it should be use utilize a grounding strap and it is the system administrator has been tasked with allowing smtb traffic through the system's host-based firewall which of the following ports should the administrator enable 23 25 80 or 161 correct answer remember we're trying to look for SMTP traffic which one does he need to do for SMTP so it should be 25 uh technician is monitoring all outbound traffic in a Soho small office home office router which of the following is the most coste effective solution to monitor the traffic Spectrum analyzer Network tap loop back plug or toner probe correct answer is Network tap uh technician recently discovered the root cause of the application error that several users have been experiencing the technician uh updated the configurations on the affected machines and verified full functionality was restored for all all users which of the following actions should the technician perform next it's not which one should he perform it's which one should he perform next write a KB article in the ticketing software to expedite future incidents submit a bug report to the developer of the application along with steps taken to resolve the issue but no one does this well I guess that I'm giving away the answer uh work with the developer to proactively collect the application logs to identify future errors of this type or send an email communication to the company about the issue and the steps taken to resolve I suppose if you have really good communication with the company but yeah so this one should be a KB article yeah uh there we go a desktop support technician is tasked with upgrading a laptop so it has the fastest data access possible which of the following best satisfies this requirement M SATA SSD M2 nvme SSD 2.5 SATA SSD or 2.5 SAS hhd that might be a typo might not supposed to be that I think that's a typo but the correct answer is this one nvme uh chief executive officer wants to ensure company data is stored in a manner that provides the company with complete control over how the data is managed which of the following is the best cloud deployment model for this request Community hybrid public or private we have a few uh videos regarding um Cloud technology as well if you're interested in more of that so complete control over how the data is managed is your key here and that is going to be private uh a user sends a print job to a network printer and the print job uses double the amount of paper is expected which of the following should the user configure to get the expected result it kind of doesn't give you all the information but you kind of get there if you think about it uh duplex coate landscape or transparency correct answer is duplex a startup company is outgrowing its current office space and it's requiring employees to work remotely the company must comply with the government enforce requirements to safeguard all aspects of data so the IT department plans to maintain complete control over users operating systems which of the following should the IT department Implement vdi IAS VPN or saas correct answer is should be vdi yeah I mean there's other ways to get there but not not the same not the same way uh which of the following would be best reason to use a virtual machine as a Sandbox to test out new software in a safe environment to increase the efficient use of computing resources to run multiple machines in the same Hardware or to have dedicated hardware for a single system correcting answer is should be this one a uh which of the following would most likely uh be used to reconnect one or more devices to the internet in a small office home office router Hub ethernet Gateway wireless access point or router I kind of gave it away didn't I yeah so the correct answer is going to be d brouter uh which of the following is the primary I'm sorry I'm not supposed to be giving away the uh the answers in the questions I don't think that really helps much which of the following is the primary security concerned with virtual machine Escape cross-site scripting compromising the hypervisor overutilization of resources or Rogue virtual machines installed on the hypervisor this one might be a little tricky should be number two compromising the hypervisor uh an IT manager is requesting that the company buy new cables to be uh to be used with F Type connectors that are ready in the house which of the F cables should the company buy coaxial plenum cat 5V or Fiber correct answer is coaxial it's the connector gives it away uh technician configured a new Soho router for small business the I the ISP gave the technician an IP address on the router's WAN Port which of the following addresses did the technician most likely configure on the router 10150 do30 1945. 7.28 169.254 16810 and 17222 40.6 correct answer is going to be B uh and I do actually want to do a video explaining why if this is confusing to you guys these are specific addresses that show that you're not connected to the Internet so I I want to do a whole video explaining that uh technician is diagnosing I mean if you guys want if you don't care then I won't do it technician is diagnosing a workstation that shuts down unexpectedly during a burn in test which the following is the most likely cause for this symptom faulty Coss battery OS update issue overheating or faulty Ram correct answer should be C overheating help desk received a ticket regarding issues with a laser printer the printer has had repairs previously for scanning issues currently the printed text is not adhering properly to the paper which of the following should be replaced to resolve this issue fuser waste container roller or [Music] toner correct answer is a fuser because it fuses uh the things to the uh the ink to sorry not the ink it fuses the toner to the paper ink yeah going be hard to find that on a uh a laser printer very hard uh technician has set up a new conference room with the TV and a video Soundbar the the technician wants to test the system with a conference call during the test the TV speaker produces sound but the sound bar does not which of the following is the most likely cause of the issue the volume of the TV needs to be turned up the conference call needs to be unmuted for audio an incorrect HDMI capable is being used or the TV's HDMI ARC Port is not being used correct answer is D the TV's HDMI ARC Port is not being used technician is setting up a projector for a video conferencing system when the user attempts to connect a laptop to the system the system displays the following error message no Source found the user tries multiple cables and inputs on the projector which of the should the user try next check the bulb on the projector and replace it with a new one check the display settings on the computer and set them to extend duplicate replace the projector with another known good one and try again or replace the video card on the machine that's plugged into the projector as it's gone bad correct answer and there's a few of these are correct but this is which of the following should the user try next check display settings on the computer and set them to extend duplicate which of the following is a method that can be used to securely connect a remote user's laptop to a corporate server when VPN SSL or DHCP remote user's laptop to a corporate server correct answer is VPN technician is inspecting a projector that is displaying fuzzy images which of the following actions would provide the best solution adjusting the lens changing the filter replacing the video cable or reting the lamp correct answer is adjusting the lens an end user discovered that the touchscreen features on a Windows device have stopped working which of the following should the technician check performance monitor tablet PC settings system configuration or display settings correct answer is tablet PC settings I got a funny well I'm not going to say this story right now but I got a funny Star regarding uh regarding that maybe I'll say it one day uh which of the following Network Services allows a network device to be to always be assigned the same IP address based on devic's Mac address DHCP loap UTM or DNS correct answer is DHCP a technician oh there's so many words here technician was called in to look at a user's PC the user reported the PC was very sluggish the HDD light on the PC was constantly on without blinking the PC itself was slow receiving input and took a very long time to load the operating system the te technician also noticed updates had failed which of the following is most likely caus of these issues the hard dri the hard disk drivers have been corrupted the HDD cables need recing a raid disc failed or the HDD has no free space correct answer is the HDD has no free space there's not really too many well it depends on the environment you're working in but not too many H uh hard dis drives spindle drives uh going around anymore they're all getting replaced with uh the ssds uh user entered a help desk ticket stating the latest calendar I mean it it's the same thing they still fill up all the time but um user entered a help desk ticket stating the latest calendar updates have not appeared on the user's corporate mobile device for several days even though updates do appear on the user's laptop which of the following actions will most likely enable calendar alerts checking the ringer volume on the device is high enough to be audible uh ensuring the corporate password is save correctly in the calendar application installing a third party calendar application synchronizing with the corpor calendar or remotely wiping the mobile device and reinstalling all applications correct answer is two ensuring the corporate pass I mean I think that there's other things that I would try first but correct answer is to uh a new version of Windows was released and a piece of software vital to the engineering department will not run on the new version which of the following is best option to enable the department to continue using this software do not upgrade up any workstations workstations within the organization upgrade all workstations and provide a virtual environment for the Lexi software upgrade all workstations except those used by the engineering department or purchase new workstations for the engineering department now this I I have uh I I have a little bit of a disagreement with because it depends on the environment that you're working in but according to CompTIA this is the correct answer is B uh technician is replacing a computer with a connected point of sale system using a 9pin Serial adapter the new computer does not have a 9-pin Serial Port which of the following ports can an adapter be installed on in order to connect to the point of sale system HDMI Bluetooth USB or lightning correct answer is USB or Universal serial bus Which of the following Network types would be used in a server room to connect virtual servers to high-speed storage when pen man or S it does help if you actually know what these uh stand for so the correct one is D St Stan yep Stan sand storage area network uh user takes a tablet to a technician because the cursor on it keeps drifting the techn notices the screen does not appear to be damaged which the Fong is the most likely cause of the cursor issue screen is physically damaged the screen rotation is incorrect the touch pen battery is depleted the screen needs to be recalibrated if you guys have ever experienced this with some of the older game consoles and the analog joysticks in them I used to get this all the time correct answer is the screen needs to be recalibrated a user reports issues with with a smartphone after dropping it the icons of the screen all look normal but when the user touches the email icon for example nothing happens which of the following most likely which of the following is most likely the cause digitizer issues overheating broken screen or malware correct answer is digitizer issues a technician is tasked with upgrading a laptop's ram which of the following steps should the technician take first first confirm that both the current and new memory are from the same brand run a diagnostic test on the current memory verify the memory requirements of the motherboard or connect an electrostatic discharge strap so the correct answer and this is hilarious because I've seen so many people not do this and wind up ordering things they shouldn't order and having to send them back verifying the memory requirements of the motherboard not me not me but I've seen it plenty of times technician is configuring a new CAD workstation that is four large hard drives the workstation will be used to edit large critical files so storage configuration should be both fast and redundant which of the following raid levels best meets these requirements 0 1 5 or 10 the correct answer is 10 RAID 10 uh we also have a video on the channel for uh understanding raid a little bit better it's got Super Mario in it I would highly recommend to uh take a look at that that's one of my favorite ones that I've uh that I've made a startup is looking to immediately expand its data center but does not have the personel or space to manage everything internally the organization has multiple small small multiple small offices and remote users with large computational and storage solution requirements funding is not an issue for the company which of the following can best accomplish can best accomplish the company's goals s IAS ISP or sdn and this is why Cloud technology has really been booming it's IAS or infrastructure as a service people getting ridiculous with the things that they're charging as a service they're making everything as a service technician receives a ticket that states a mobile payment device is having issues with it contactless payment feature the device is not detecting payment options which of the following is the most likely cause of the issue NFC Bluetooth wifi or lightning adapter correct answer is NFC or nearfield Communications that's what these devices use to communicate uh a user wants a second monitor installed on a laptop the vgi VGA DVI or HDMI cables have already been connected which of the following should the technician do to configure the laptop to show both screens power cycle the laptop plug in the monitor to the USB port adjust the monitor display settings or power cycle the monitor correct answer is adjust the monitor display settings which of the following allows the allows all VMS in a virtual environment to have Ram allocated for use measured service containerization synchronization or resource pooling correct answer is resource pooling which of the following 80211 standard support both supports both 5 GHz and 2.4 GHz Channel frequencies 80211 a 80211 AC 80 21b or 80211 G it's very conf I don't think I've ever used any of this in the field uh well I maybe I guess I don't know uh correct answer is 80211 AC uh a hardware technician is configuring a laptop and the network like I've never had to know which I guess I guess I have never mind I guess I have Hardware technician is conf I'm always try to find faults with these and then wind up eating my words don't I Hardware technician is configuring a laptop and the network administrator requires the network settings to be static the technician successfully pings the servers by IP address but cannot ping the UNC path which of the following is the cause of the issue domain name system Gateway subnet or IP address correct answer is domain name system or DNS and an organization is looking to upgrade the processing ability of its computers most users report that whenever multiple applications are being utilized the system's response time slows down drastically when only one application is open the response time is acceptable which of the following should be upgraded first SSD CPU HDD or Ram feel like this is one of those gimmies the correct answer is RAM and one thing to mention is that there are certain applications you wouldn't expect to have a be like resource Hogs Excel especially in huge uh huge spreadsheets is a huge resource hog and uh teams is another one uh client side virtualization guest machines have security requirements similar to physical machines but they also need to ensure separation from other guest machines which the following best describes this client side guest security requirement isolation Authentication hardening or authorization correct answer is isolation a user connects a smartphone to a laptop which of the following types of network has the user created Pan Man W Lan or LAN correct answer is pan or personal area network several users who share a multi-function printer in an office have reported unintended thin vertical lines that cover the entire height of every page printed from the printer which of the following steps should a technician complete in order to most likely resolve this issue replace the printer paper with a new ream clear The Print Spooler on each computer reinstall the printer driver on each computer or perform the drum cleaning procedure correct answer is perform the drum cleaning procedure which of the following should the data center Hardware technician Implement to ensure maximum uptime for customers virtual machines line conditioner ac voltage regulator uninterruptable uninterruptible power supply or cloud storage backup correct answer is C uninterruptible power supply or UPS a technician needs to improve a workstation overall response time for frequently used applications and data without removing the current hard drive which of the following storage devices should the technician install to best complete this objective M2 SAS HDD or SCSI also referred to as scuzzy sometimes times correct answer is M2 technician is setting up a device to use two Factor authentication which of the following meets this requirement thumbprint retinal scan password password password thumbprint or password pin correct answer is password thumbprint cuz it's one type of uh authentication and another type of authentication a user brings an older laptop to the help desk and reports issues with the keyboard upon inspection the technician does not see any external damage but notices that many keystrokes do not register in a word processor the laptop works fine when the te technician tests it with an external keyboard which of the following actions would most likely resolve the issue disable the sticky keys feature clean the keyboard reset the bio settings to default or charge the laptop correct answer is to clean the keyboard an administrator is configuring a corporate owned smartphone for a new manager the company requires the ability to wipe the phone's data remotely in the event of a loss of theft loss of loss let me try that again loss or theft and the ability to approve applications installed on the phone which of the following tools would best meet this need tethering to a corporate owned laptop WPA2 Enterprise Wireless corporate Enterprise email or mobile device management correct answer is mobile device management or MDM you might he referred to it as MDM a user reports that printed receipts have black smudges over the entire image the text is still present but is very dark and sometimes illegible which of the following are the most likely cause and solution for the printer issue the ribbon is jammed and rubbing on the paper clear the bad ribbon and feed it through properly the print head is too hot adjust the temperature down and retry printing the printer is loaded with the wrong type of paper replace the receipt paper with carbon paper or the blue ink cartridge was loaded with black ink put the correct ink and clean the print head correct answer is print headed is too hot adjust the temperature down and retry printing I don't know why that one didn't want to work uh developer is requesting permission to utilize client side virtualization I'm hoping there's not a bug in this because that would mean that I mess it up uh developers requesting permission to utilize client side virtualization the developer would like to write code in a setting isolated from other infrastructure to avoid negative impacts of experimental code which of the following provides the best solution for the developer crossplatform functionality software compatibility test case development or sandbox [Music] environment correct answer is a Sandbox environment the IT department at an insurance brokerage needs to acquire laptops that have built in fingerprint readers in order to create a more secure environment which of the following would be the most secure way to implement the fingerprint readers Grant all registered employees access to each machine restrict device access to only the user to whom the laptop is assigned limit device access to departments and guest users or give each team member USB drive that bypasses the reader to allow guest users to log in correct answer is restrict device access to only the user whom the laptop is assigned a laptop's external webcam software is running but it shows no image or video which of the following should a technician perform perform first research new webcam firmware restart the computer and run system Diagnostics receip the webcam reinstall the webcam software and drivers correct answer is reat the webcam the age-old did you turn it back off and turn it off and turn it back on again uh an engineer is experiencing unexpected reboots on a graphics workstation with when rendering uh complex 3D models the workstation is configured with a 115 volt power supply that is rated at 200 watts and connected to a UPS the central processing unit contains 16 hyperthreaded cores and a discret graphics solution utilizing an 8 Pin power connector is installed in a PCI Express x16 slot which of the following indicates where the technician should begin troubleshooting the UPS as 115 volts is insufficient for the configuration and should be increased to 200 volts the power supply as 200 watts is insufficient when the GPU is heavily tasked the graphics card as it is the component that trigger the unexpected reboots or the motherboard as only standard PCI slots should be used for high-end graphics cards not PCI Express slots correct answer is the power supply as 200 watts is insufficient when the GPU is heavily tasked I feel like I would have approached this a different way though uh that's the CompTIA answer uh which of the following Technologies can allow multiple networks to Traverse a switch VLAN vrrp VPN or DHCP correct answer is the VLAN virtual local area network an end user reports that the time and date on a desktop resets after shutdown and subsequently the device reboots the next day the desktop does not load the OS and is stuck at a black screen with the following message dat time not set press F1 to run setup which of the following would be the best action to take next change the motherboard reseat the motherboard power connection replace the Coss battery or restore the bias to factory default settings correct answer is replace the C Moss battery is that little tiny silver battery that is connected with a little cable on your uh system board and I'm sure you're always wonder I'm sure some people are always wondering what uh what that's for but well you guys probably aren't wondering you already know what it's for user reports that a PC occasionally fails to boot the user reboots the PC but the performance is degrading the technician hears a strange repetitive ticking noise coming from the PC which of the following should the technician do first try to extract data rece the ram modules inspect the fan or check the CD tray correct answer is a try to extract data because that is going to be the hard drive so that's not going to happen on a uh SSD though uh technician is upgrading a faulty motherboard that was replaced uh that was ordered by an end user for an old high-end desktop computer however the technician is unable to install the CPU into the socket upon closer inspection the technician notices the pins on the CPU do not line up with the socket which is the following with the best course of action for the technician to take next try to set as many pins as possible install an adapter to create a universal socket verify the socket type in manufacturer or find a compatible motherboard for the CPU correct answer is verify the socket type and manufacturer a remote user uh reports connectivity issues with the local internet provider even after a technician reboots the mo the modem supplied by the ISP the issue persists which of the following would best establish the connection in minimal time radio frequency ISP neighbors Wi-Fi mobile hotspot or Fiber Optic so the giveaway here is to establish in minimal time and that is the hot spot ay because you can just set that up really quick uh a company wants to give third-party developers access to the corporate Network through desktop environments that the company can control which of the following can best achieve these requirements sandbox vdi private cloud or saas correct answer is vdi which of the following which of the following utilizes TCP ports 20 and 21 and transfers data in clear text I know you guys are going to get this SNMP SSH FTP or telnet correct answer is Ft FTP or file transfer protocol a user's mobile phone gets really hot to the touch and does not retain a charge the user also reports that the phone is very slow especially while charging which of the following is most likely causing these symptoms broken charging port digitizer failure CPU overheating or defective battery correct answer is defective battery also a lot of times the case will swell up and you'll notice a like a bubble or a pillow so that's something to take care of as soon as you notice uh a Microsoft Windows user is preparing to work in another country and needs to comply with corporate policy for data protection when when copying files to portable media which of the following solutions would most likely satisfy this requirement USB 3.1 flash drive with bit Locker to go installed an SD memory card with NTFS uh an XD memory card with ext3 or a portable hard drive with fat 32 correct answer is a USB 3.1 flash drive with bit loock lock ER to go installed so it's also keep in mind corporate policy for data protection uh which of the following network devices is used to separate broadcast domains switch wireless access point router or Hub correct answer is C router a user submits a help desk ticket regarding the smartphone that will no longer accept its charging cable the assigned technician notices the phone does not have a protective case and the user constantly transports the phone in a pocket the technician attempts to use a secondary charger but the cable falls out of the phone which of the following is the most likely cause of the issue the phone requires a firmware update to address charging issues the charge port contains foreign objects such as lint the phone's battery has swelled preventing the utilization of the charge port or the phone has experienced water damage thus the battery is not charging correct answer is the charge port contains foreign objects such as lint a network administrator was noticed that laptop users are or bugs not saying that uh I've seen that firsthand but I've seen that firsthand uh a network administrator was notified that laptop users are unable to access or ping any network resources on the corporate Network which of the following should the network administrator check first DHCP AAA DNS or arp correct answer is DCP upon booting a workstation a technician Hears A distinct clicking sound after power is applied to the motherboard which of the following would most likely cause the issue this one's not bugs that's that's the last one actually that's that's where the term bugs comes from but back on topic uh raid SSD smart or HDD correct answer is HDD this is the spindle drive and that's what's going to make that sound the ssds are not going to make that sound an organization has some computers running Mac OS and some computers running Windows the computers running Mac OS also need to run a piece of software that is only available on Windows which of the following best describes the solution for running Windows software on a computer running Mac OS operating system spoofing remote software provisioning indirect software implementation or crossplatform virtualization correct answer is crossplatform virtualization uh or virtual machine uh fuel technician has been dispatched to a site with an internet outage upon arriving the technician discovers that the pots lines PS lines are not working as well which of the following Technologies is the site most likely using fiber cable DSL or satellite correct answer and I've never seen this on uh on a test is DSL uh company wants to use all of these are supposed to be test based like actually things that have been on uh on the A+ exam this specific A+ exam um a company wants to use I mean you'll see a variation of questions not necessarily these questions specifically because then it' be very easy to know exactly what's on test but you know there's like a thousand different questions they pull from or something like that uh a company wants to use client side virtualization for application testing which of the following configurations would best support this goal CPU 2.5 GHz four cores uh 16 GB ddr4 Ram 1 terabyte SSD CPU 3.2 GHz 1 core 16 GB of ddr4 Ram 4 tab SSD CPU 2.5 GHz two cores 16 GB ddr4 Ram 4 1 terabyte hard drives with raid five or CPU 3.2 GHz four cores 8 GB of ddr4 RAM with a 500 GB hard drive best one is the first one CPU this is the one with the four cores four cores 16 GB of RAM and one tab hard drive they just the best suited for the VMS a User submitted a ticket to report an issue with a new printer that is no longer accepting new print jobs the technician verifies the printer is on and notices the printer LCD screen has the following error message paper jam Jam infuser which of the following is the most efficient Next Step the technician should complete apply maintenance kit to the printer check the printer paper path to locate any obstructions turn the printer on and off to see if the eror clears or replace the fuser correct answer is check the printer or paper path to locate any obstructions a technician unboxed a new computer plugged it into a UPS and connected the requested peripherals the computer lights and fans turn on but the technician hears three loud consecutive beeps during boot which of the following actions will remediate this issue replacing the power supply replacing the UPS changing the Coss battery or reating the ram correct answer is reting the ram also there are little lights on the computer that will blink in certain patterns uh and sometimes certain colors as well and they will if you check the manufacturer information it will tell you what the error code means uh an IT manager discovered that hundreds of pages of printed materials are being recycled each day because the materials are left on the printer tray instead of being picked up by the users which of the following would best prevent this waste send friendly reminders to not print unnecessarily enable duplex printing to reduce paper utilization build each department for the excess material cost or require code or badge before releasing a print jot correct answer is D require code or badge before releasing a print job but a lot of companies do this for security reasons uh an online retailer wants to save money and is considered migrating to the public Cloud so capacity can be added during the peak shopping season and automatically remove when the peak is over which of the following best describes this aspect of cloud computing rapid elasticity metered utilization shared resources or high [Music] availability correct answer is rapid elasticity uh technique is receiving reports that the entire office sporadically loses network connectivity throughout the day a technician determines the root cause to be Emi which of the following cable mediums would be the most costeffective without sacrificing system performance coaxial shielded cat 6 plenum cat 5e or multimode Fiber correct answer is shielded cat 6 an organization maintains various record types including health and Criminal Justice Records which of the following Cloud environments is the organization most likely to use to limit the attack surface public hybrid Community or private correct answer is D private cloud or on Prem where you control all of the hardware yourself a colleague has a laptop that's been working as expected for several years but the laptop now has a small bulge in the bottom casing and overheats occasionally when plugged into a wall outlet the most likely component that needs to replaced is power adapter battery system fan or hard drive correct answer and we've actually mentioned this a few minutes ago is the battery company just bought a printer cable of automatically printing uh sorry company just bought I'm like what that doesn't make sense company just bought a printer capable of automatically printing on both sides of the paper after installation however the technician can only print on both sides of the paper manually which of the following should the technician do to fix the issue install the most recent firmware upgrade available for the printer contact the vendor for a hardware replacement reinstall the printer software and drivers then restart the printer or read the installation manual and configure duplex settings correct answer is D read the manual rtfm and uh configure the settings uh a small office has a wireless network with several access points for roaming laptop use users occasionally report that the wireless connection drops or becomes very slow users have confirmed that this is the this issue only happens when connected to the office wireless network which of the following would most likely be the cause hidden SSID device interference ethernet port flapping or high ISP latency correct answer is device interference which of the following Cloud models maintains access even when a local internet outage occurs private SAS Community or public that would be private Cloud where you have access to to it physically not always physically but usually physically uh a laptop has been returned for a screen repair the owner insists the screen is broken but occasionally a faded image is able to be seen in very bright settings on the desktop which of the following should the repair technici take first replace the graphics card replace the screen as the customer insists recommend the usage of an external display instead or ensure the backlight is functioning as expected correct answer is ensure the backlight is functioning as expected a laptop PC user is reporting issues with a hard drive a file system check shows that all files are accessible and the file system is clean after the check the PC still issues a hard drive error message which of the following is the most likely cause of the error smart failure iops failure dim failure or Raid failure correct answer is smart failure technician is tasked with installing additional RAM in a desktop computer which of the following types of RAM is most likely to be used sodm DDR3 ECC or vram correct answer is DDR3 also a great game uh well I I don't I've never played it but uh I hear while implementing a non-carrier grade Wireless back hall a technician notices the current channel selection is extremely polluted with various RF signals upon performing a spectral analysis the technician discovers a channel containing almost no RF pollution unfortunately the technician is unable to select that channel which of the following is the most likely reason for this issue the channel is reserved for license band use the channel selection is defective contact the manufacturer or the channel must be unlocked locked by a vendor or the device requires a firmware update to unlock the channel correct answer is the channel is reserved for licensed band use a user's computer is not receiving a network connection the technician confirms that the connection seems to be down and looks for the users port on the patch panel the port and Patch panel are not labeled which of the following Network Tools should the technician use to identify the port Network tap punch down tool toner probe or crimper correct answer is C toner probe a user who is attempting to give a presentation via a projector in a conference room reports that the projector has video but no audio which of the following will most likely resolve the issue changing the input on the projector to VGA changing the output on the PC to DVI modifying the projector's refresh rate or utilizing an HDMI connection correct answer is utilizing an HDMI connection a customer reports that a computer is never able to reach more than 100 megabits per second transfer data rate even when using a gigabit landan card while troubleshooting the technician notices the network cable needs to be replaced which of the following cable categories is limiting the transfer speed Cat 5 cat 5e cat 6 or cat 6 a correct answer is cat five while
