4A0-101 Exam - Question 32


In IS-IS database synchronization, each router compares each LSP described in the received CSNPs with the LSPs in its own database. Which of the following actions is taken if the database contains a newer copy of the LSP?

Show Answer
Correct Answer: A

In IS-IS database synchronization, if a router finds that its own database contains a newer copy of an LSP compared to what is described in the received CSNPs, the router sends a copy of the LSP from its database to its neighbor. This ensures that all routers in the network have the most current link-state information, maintaining consistent and up-to-date routing tables.

A is correct, once the router found that the LSP is older on the CSNP received, the router will send an LSP.
