Question 1

What are the BGP Packets and Their Main Duty?

A	QUALIFY : Differentiates differetn packet types
B	KEEPALIVE : Handshake in regular intervals.
C	UPDATE : Announces new routes or withdrawing previously announced routes.

Question 2

An ..... acts as the meeting place for sources and receivers of multicast data in a PIM-SM network. In this network, sources must send their traffic to the RP. This traffic is then forwarded to receivers down a shared distribution tree.

B	Multicast
C	Unicast
D	Anycast

Question 4

What are the Opaque LSAs? Why are they used?

B	LSA Type 10 - Used to extend OSPF functionality and MPLS-TE
C	LSA Type 8 - Used for OSPFv2
D	LSA Type 7 - Used to extend OSPF functionality and MP-BGP
E	LSA Type 9 - Used for OSPFv3

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

Question 13

Which Ones are True for Route Distinguisher and Route Target?

A	The route target defines which prefixes get imported and exported on the P routers.
B	The route target defines which prefixes get imported and exported on the PE routers.
C	The route distinguisher makes a unique IP address across the MPLS network.
