B. 3
C. 4
D. 6

CCNP Certification / BSCI Exam:
An OSPF-enabled router receives an LSA. The sequence number is lower that the most recent LSA received for that link. What will the receiving router do?
A. Accept the update and update its OSPF database.
B. Accept the update and take no further action.
C. Accept the update, update its database, and flood the changes.
D. Ignore the update and take no further action.
E. Ignore the update and send an LSU back to the original sender.
Answer: E. If a router running OSPF receives an update with an LSA that has a lower sequence number than the one it already has in its database, that indicates that the just-received LSA is not the latest information regarding that link.
The receiving router will not only ignore the update, but will send an LSU containing the latest LSA regarding that link back to the original sender.
