Alcatel-Lucent NRS II – Wide Area Network Services — Question 15

The destination IP address of a received unlabeled packet is successfully matched in the FIB.
Which of the following is FALSE?

Answer options

• A. A POP label stack operation may be performed.
• B. The outgoing interface and next-hop address will be determined from the FIB.
• C. The packet can be forwarded as a labeled or unlabeled packet.
• D. A PUSH label stack operation may be performed.

Correct answer: A

Explanation

Option A is incorrect because a POP operation is not applicable when the packet is unlabeled and the FIB lookup is successful. The other options correctly describe the behavior of the network device in this situation, as the FIB provides the necessary information for forwarding the packet appropriately.
