Question No. 1

The users who log on the router through Telnet are not permitted to configure an IP address. What is the possible reason?

Show Answer Hide Answer
Correct Answer: A

Comprehensive Explanation= In Telnet sessions, different privilege levels determine what actions a user is allowed to perform. If users are not able to configure the IP address, it is likely that their privilege level is set incorrectly. The administrator must ensure that the Telnet users are assigned the correct privilege level (typically level 15 for full administrative rights) to allow configuration changes, including IP address modifications.


Question No. 2

If the transport-layer protocol is UDP, the value of the "Protocol" field at the network layer is 6.

Show Answer Hide Answer
Correct Answer: B

In the IP header at the network layer, the Protocol field specifies the transport layer protocol in use. The protocol number for UDP is 17, not 6. Protocol number 6 is reserved for TCP. This field allows IP packets to be correctly processed by the appropriate transport-layer protocol at the receiving device.


Question No. 3

A router that runs OSPF can enter the Full state only after Link-State Database (LSDB) synchronization is completed.

Show Answer Hide Answer
Correct Answer: A

The Full state in OSPF means that all routers have completed LSDB synchronization and formed an adjacency.

If LSDB synchronization is incomplete, the router remains in Loading or Exchange state.

Only after the Database Description (DD) packets, Link-State Requests (LSR), and Link-State Updates (LSU) are exchanged, the router enters the Full state.

Thus, the correct answer is A (TRUE).


Question No. 4

Which of the following is not included in the routing table?

Show Answer Hide Answer
Correct Answer: A

Comprehensive Explanation= A routing table contains information necessary for the router to determine the best path to forward packets. This includes the destination network or subnet (Destination/Mask), the next-hop address (the IP address of the next device in the path), and the cost (metric) associated with the route. MAC addresses are used at the Data Link layer (Layer 2) for local network communication and are not part of the routing table, which operates at the Network layer (Layer 3).


Question No. 5

(Which of the following statements about IPv6 anycast addresses are true?)

Show Answer Hide Answer
Correct Answer: A, C, D

IPv6 Anycast Address Characteristics:

Option A: True. Packets are delivered to the nearest interface based on routing distance.

Option B: False. Anycast addresses are not designed for load balancing.

Option C: True. Anycast addresses share the same address space as unicast.

Option D: True. Anycast provides redundancy by allowing multiple endpoints to share the same address.
