1.	An OSPF router receives an LSA. The router checks its sequence number and finds that this number is higher than the sequence number it already has. Which two tasks does the router perform with the LSA?(a) Ignores the LSA(b) Adds it to the database(c) Sends newer LSU update to source router(d) Floods the LSA to the other routersThis question was addressed to me during a job interview.This interesting question is from OSPF Configuration in portion Network Layer of Computer Network
Answer» The correct CHOICE is (b) Adds it to the database Easiest explanation: An OSPF router RECEIVES an LSA. If the router checks its sequence number and finds that the number is higher than the sequence number of the LSA that it already has, the router adds it to the database, and then floods the LSA to the other ROUTERS.
