Sample questions

1. What is the basic function of a network interface card (NIC)?

   1. To process data
   2. To connect a computer to a network
   3. To store data
   4. To manage power
   Show answer

   Answer: B. To connect a computer to a network

   A NIC is a hardware component that allows a computer to connect to a network.

2. What does TCP/IP stand for and what is its primary function?

   1. Transmission Control Protocol/Internet Protocol; routing data packets
   2. Transfer Control Protocol/Internet Protocol; managing files
   3. Transmission Control Protocol/Internet Protocol; securing networks
   4. Transfer Control Protocol/Internet Protocol; encrypting data
   Show answer

   Answer: A. Transmission Control Protocol/Internet Protocol; routing data packets

   TCP/IP is the fundamental communication protocol suite for the internet. TCP ensures reliable data transmission, while IP handles addressing and routing.

3. What is a firewall and how does it enhance network security?

   1. A physical barrier protecting network devices
   2. A software or hardware that controls network access
   3. A software for data encryption
   4. A network topology
   Show answer

   Answer: B. A software or hardware that controls network access

   A firewall examines network traffic and blocks unauthorized access attempts, enhancing network security.

4. Describe the functionalities of a Domain Name System (DNS) server and its importance in internet navigation.

   1. Translates domain names into IP addresses
   2. Manages email accounts
   3. Stores web pages
   4. Secures network connections
   Show answer

   Answer: A. Translates domain names into IP addresses

   DNS servers are essential for translating human-readable domain names (e.g., google.com) into machine-readable IP addresses.

5. Discuss the challenges in implementing and managing large-scale enterprise networks, including scalability, security, and cost optimization.

   1. Scalability requires flexible architecture; security demands robust measures; cost involves hardware, software, and personnel
   2. Only scalability is a challenge
   3. Only security is a challenge
   4. Only cost is a challenge
   Show answer

   Answer: A. Scalability requires flexible architecture; security demands robust measures; cost involves hardware, software, and personnel

   Large networks face complex challenges across various domains that need careful planning and management.
