E	LSU (Updates with multiple LSAs)
F	TCN (Topology Change Notification)
G	LSDB (Link State Database)

Question 13

Why is BFD Used?

A	A mechanims used to provide network management instead of the protocol snmp.
B	A mechanims used to provide redundancy with routing protocols.
C	A mechanims used to provide quality of service in the network.
D	A mechanims used to provide rapid link failure detection instead of routing protocol hellos.

Question 14

A	It is used to provide redundancy in BGP networks.
B	It is used to eliminate the full mesh requirement for building iBGP networks.
C	It is used to enhance BGP network.
D	It is used to provide eBGP neighbourship establishment.

Question 15

Next Hop remains unchanged when route is advertised to IBGP peer; however, it is changed when it is advertised to EBGP peer by default. .... Command provides to change next hop, while advertising, as a local route.

A	peer
B	neighbor
C	next-hop-self
D	network

Question 16

What are the Opaque LSAs? Why are they used?

A	LSA Type 9 - Used for OSPFv3
