next step in your certification Journey this video is filled with 200 plus questions that closely resemble the real exam and will help you to gauge your Readiness so are you prepared to test your knowledge great let's begin question one which type of RAM is a technician most likely to install when upgrading a desktop computer the answer is b dbr4 double data rate or dbr Ram is the expected choice for upgrading a desktop computer's memory due to its wide adoption and compatibility with the memory slots found on desktop motherboards so dim modules are smaller and used in laptops not desktops ECC memory has error correction useful for servers but is overkill for most Des tops vram is dedicated to graphics cards and isn't used for General system upgrades question two what is the most likely reason for vertical streaks on the printouts from a laser printer the answer is B drum vertical streaks and laser printer outputs are most commonly attributed to issues with the Drone unit the drum surface is sensitive and integral to image transfer damage or wear on it can lead to repeating streaks on printouts toner buildup on the drum can also cause streaks this typically results from a failure of the drum's cleaning mechanism to fully clear away residual toner after each print cycle question three a user is attempting to play a DVD on a projector while the audio plays normally the project vtor is showing an error message that states HDMI content disabled due to copy protection what is the most probable cause of this error the answer is seed the projector does not support the required hdcp protocol the error message indicating HDMI content disabled due to copy protection suggests a problem with hdcp compliance which is a protocol used to prevent unauthorized copying of digital audio and video if the projector lacks support for the necessary hdcp standards it won't display the video from an hdcp protected DVD although the audio might still transmit since it is less often protected question four while setting up a new wireless network a technician identifies that the current channel is heavily congested with competing radio frequency signals after conducting a spectrum analysis the technician finds a channel that is clear of significant RF interference but is restricted from switching to this Chan what is the most probable explanation for the inability to select this channel the answer is a the channel is restricted for licensed band use radio frequency spectrum regul ations often Reserve certain channels for licensed entities such as commercial broadcasters or government agencies to prevent interference with critical Services these restricted banss are not available for public or unlicensed use and Equipment designed for General use is typically configured to avoid these channels to comply with regulatory standards question five a technician is setting up a computer to serve as a host for virtu virtual machines following the installation of the required virtualization software the technician finds they cannot create any virtual machines what should be the next step to troubleshoot this issue the answer is B enable TPM enabling The Trusted platform module or TPM is often necessary when setting up a virtual machine host as many virtualization Solutions require TPM for security functions like secure Boot and Hardware based encryption if the TPM is not active the system may not fulfill the security standards demanded by the virtualization software which can lead to the creation of VM being blocked therefore turning on the TPM in the Bios or UEFI settings could resolve the issue allowing the technician to proceed with creating virtual machines question six a user's PC is experiencing network connectivity issues the technician verifies the network outage and proceeds to locate the corresponding port on an unlabeled patch pound what network tool is most appropriate for the technician to use in order to identify this port the answer is C toner Pro a toner probe is an Ideal tool for locating an unlabeled Network port on a patch pound the technician can use the toner part to send a signal from the user's PC end of the cable and then sweeps the probe across the patch panel the probe detects the signal and responds with an audible tone when it's held near the correct Port thus allowing the technician to identify which Port corresponds to the user's computer without the need for Visible labeling question seven during a presentation in a conference room a user finds that while the projector is displaying video there is no accompanying sound what is the most effective solution to fix the audio problem the answer is D use an HDMI connection choosing an HDMI connection can quickly resolve audio issues when a projector displays video without sound because HDMI transmits both audio and video signals if the current setup uses a connection like VGA or DVI which only carries video the user won't hear any Sound by switching to HDMI the audio should be transmitted seamlessly to the projector thereby streamlining the setup and eliminating the knee for separate audio cables question eight a client has observed that their computer does not exceed a 100 megabits per second data transfer rate despite having a gigabit Nick install upon inspection the technician realizes that the network cable is responsible for the limitation which category of network cable is most likely being utilized the answer is a CAT 5 a category 5 or Cat 5 cable is likely causing the data transfer rate to cap at 100 megabits per second despite the computer having a git Nick Cat 5 cables have a maximum bandwidth of 100 megabits per second which is inadequate for gigabit Ethernet requirements to achieve the higher speeds that the gigabit Nix supports a cat 5e or higher rated cable which can handle one gigabit per second would be necessary therefore replacing the outdated Cat 5 cable with a more advanced category would resolve the speed limitation issue question n in a widely used video conferencing application a user tries to activate their webcam without success despite it functioning the day before what steps should be taken first to resolve this webcam issue the answer is a close other applications that are using the webcam to fix a webcam not activating in a video conferencing app the first step is to close any other programs that might be using it webcams can only be accessed by one application at a time so if another application has not released the webcam the conferencing software won't be able to connect to it shutting down any potential conflicting software allows the webcam to be accessed by the desired application question 10 an individual was unable
