Correct Answer: A. A. Ipsec
Explanation: ESP is a security component of IPSec. ESP provides content protection and ensures that there is integrity and confidentiality of the message. The other security components of IPSec are Authentication Header and Internet Key Exchange.

Correct Answer: B. B. Cisco
Explanation: L2F stands for Layer 2 Forwarding protocol. It was designed by Cisco to tunnel PPP traffic, helping create VPNs over the internet.

Correct Answer: B. B. Layer 2
Explanation: PPTP stands for Point-to-Point Tunneling Protocol. PPTP is a tunneling protocol that was primitively used to create VPNs. It is no longer used for VPNs due to the lack of security it provides.

Correct Answer: C. C. Layer 3
Explanation: IPSec is a set of protocols used to provide authentication, data integrity and confidentiality between two machines in an IP network. It operates in the network layer.

Correct Answer: C. C. File server
Explanation: A file server allows LAN users to share computer programs and data. It uses the File Transfer Protocol to provide this feature on ports 20 and 21. The file server works as a medium for the transfer.

Correct Answer: A. A. Shielded twisted pair cable
Explanation: For physical media, STP cable stands for Shielded twisted pair cable. 100 Mbps is the max data capacity of STP cable and its default connector is RJ45. It is popularly used in LANs due to its ease of maintenance and installation.

Correct Answer: A. A. LAN intrinsic software
Explanation: A standalone program that has been modified to work on a LAN by including concurrency controls such as file and record locking is an example of LAN intrinsic software. They are used to give better functionality of the program and the applications working over it to the users of the LAN.

Correct Answer: B. B. Security management
Explanation: The Security management portion of LAN management software restricts access, records user activities, and audit data. It is responsible for controlling access to the network based on predefined policy. The security management ensures authentication, confidentiality, and integrity in the LAN.

Correct Answer: C. C. 100 m
Explanation: The max the Shielded twisted pair cable is 100 meters. If the length exceeds 100 meters, the loss of signals flowing through the cable would be really high. Thus, STP cable is more suitable for smaller networks like LANs.

Correct Answer: B. B. 100 mbps
Explanation: 100 Mbps is the max data transfer rate that can be handled by STP cables, and its default connector is RJ-45. 100 Mbps is a feasible data transfer rate for small networks like LANs.
