A	Yes
B	No

Question 8

F	PE Router

Question 10

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	RSVP-TE
C	IGMP
D	LDP

Question 16

Which Ones are True for Route Distinguisher and Route Target?

A	The route distinguisher makes a unique VPNv4 address across the MPLS network.
