Question 121

What kind of BGP attribute is the Multi_Exit_Disc?

A.Well-known mandatory attribute.

B.Well-known discretionary attribute.

C.Optional transitive attribute.

D.Optional non-transitive attribute.

Question 122

One Route Distinguisher is assigned per VRF. If CE1 and CE2 advertise prefix 10.1.1.0/24, which of the following statements is FALSE?

A.The route reflector receives two routes for prefix 10.1.1.0/24; one from PE1 and one from PE2.

B.PE1 and PE2 advertise the same VPN route to the route reflector.

C.PE3 receives two routes and is able to load balance traffic across PE1 and PE2.

D.The route reflector reflects two routes for prefix 10.1.1.0/24.

Question 123

Click on the exhibit below.

Assume PE-1 has a mesh-sdp configured to every PE node in both Metro networks. What could be done to prevent the bandwidth replication between Metro 1 and Metro 2?

A.PE-1 must be configured with mesh-SDPs to every node receiving the multicast traffic. There is no way to reduce the replication or bandwidth.

B.PE nodes in Metro 1 could be configured with spoke-SDPs. PE nodes in Metro 2 would be configured with spoke-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a mesh-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

C.PE-1 can be configured with spoke-SDPs to every PE node in both Metro networks. This will reduce the bandwidth and replication within the network.

D.PE nodes in Metro 1 could be configured with mesh-SDPs. PE nodes in Metro 2 would be configured with mesh-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a spoke-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

Question 124

Which of the following about a full mesh VPRN is FALSE?

A.Site redundancy can be achieved by dual homing a single CE to one or more PEs.

B.Dual CEs connected to redundant PEs can provide redundancy within a single site.

C.Provider core LSPs can be LDP-based or RSVP-based.

D.The provider core maintains a full mesh of LSP tunnels and MP-BGP sessions between all P devices.

Question 125

AS 65540 is using MPLS to provide BGP shortcuts for its iBGP routing. AS 65541 is advertising prefix 192.168.1.0/27 into BGP. Which routers have the BGP update for the advertised prefix in their BGP table?

A.Routers R1, R2, R3, R4 and R5.

B.Routers R1, R2, R3 and R4 only.

C.Routers R1, R4 and R5 only.

D.Routers R1and R4 only.
