What types of cloud computing models exist, and what is one benefit of each?
Press to flip
Public cloud (scalable and cost-efficient), private cloud (high security and control), hybrid cloud (flexibility), and custom cloud (tailored solutions).
List the main goals of network security.
The main goals of network security are to ensure confidentiality, integrity, and availability of data.
What are some examples of security threats to networks?
Security threats include external threats like viruses and denial of service (DOS) attacks, and internal threats like employee misuse.
What are some common intermediary devices used in networking?
Common intermediary devices include switches, routers, and firewalls.
What role did networks play during the COVID-19 pandemic?
Networks were essential for communication and enabled global connectivity and remote workforces.
What is the primary difference between a LAN and a WAN?
A LAN (Local Area Network) covers a small geographical area, while a WAN (Wide Area Network) covers a large geographical area.
What defines a home and small office (SOHO) network?
A SOHO network is designed for a limited number of devices and typically serves a small area, like a single home or small business.
What are the characteristics of a reliable network?
A reliable network has fault tolerance, scalability, Quality of Service (QoS), and security.
Name and describe two types of internet connection suitable for a business.
Lease lines, which provide a dedicated and stable connection, and Ethernet WAN, which is cost-effective and suitable for connecting various business sites.
Explain the client-server model in networking.
In the client-server model, servers provide information or services to client devices, which request this information or these services.
Describe the difference between physical and logical network topologies.
Physical topology refers to the actual physical layout of the network devices, while logical topology describes how data flows logically across the network.
How does the CCNA certification benefit network professionals?
The CCNA certification validates foundational networking knowledge, opening opportunities for jobs in network engineering and related fields.
How do network diagrams facilitate network management?
Network diagrams, also known as topologies, visually represent devices and their connections, making it easier to understand and manage the network layout.
Identify a key trend in networking and briefly describe its impact.
Bring Your Own Device (BYOD) is a key trend that allows employees to use their personal devices for work, increasing flexibility and potentially lowering costs.
What is the advantage of implementing a peer-to-peer network?
Peer-to-peer networks are easier to set up and don't require a central server, making them more affordable for small networks.
