Question 1

What is a switch?

Correct Answer: A switch is a network device used to connect multiple devices together and facilitate communication between them.

A switch is indeed a network device, and its primary purpose is to connect multiple devices together on a Local Area Network (LAN), enabling the exchange of data packets among them. Selecting answer 'A switch is a network device used to connect multiple devices together and facilitate communication between them' is the right choice. Explanation for other answers: Answer 'A switch is a type of firewall used to block incoming traffic from untrusted sources.' is incorrect because a firewall, not a switch, functions to block untrusted incoming traffic. Similarly, answer 'A switch is a type of VPN connection used to encrypt data being transmitted over the network' is wrong, as a VPN is used for encryption, not a switch. Finally, 'A switch is a type of network analyzer used to monitor network traffic' is also false because a network analyzer, not a switch, is utilized for network traffic monitoring.

Question 2

What is the purpose of a NIDS?

Correct Answer: To detect and alert administrators of network intrusions

The main purpose of Network Intrusion Detection Systems (NIDS) is to detect and alert administrators of network intrusions. They are designed to identify unauthorized, malicious activity on a network. The other answers are incorrect because they refer to different aspects of networking. While traffic filtering can be part of intrusion detection, it is not the primary purpose of a NIDS. Network bandwidth allocation and providing remote access are not related to the function of a NIDS.

Question 3

What type of cable is used to connect a computer to a switch?

Correct Answer: Ethernet

Ethernet cables are the common type of network cables used for wired networks. They are used to connect devices within a local area network, like computers to switches. While HDMI, USB and VGA are types of cables used to transmit data or video, they are mostly not used for network data transmission between a computer and a switch.
