Question 1

How can shared services in an MPLS Layer 3 VPN provide Internet access to the customers of a central service provider?

Options :

A : The CE router can establish a BGP peering to a PE router and use the PE device to reach the Internet

B : Route distinguishes are used to identify the routes that CEs can use to reach the Internet

C : The customer VRF uses route targets to import and export routes to and from a shared services VRF

D : Static routes on CE routers allow route leakage from a PE global routing table

Answer: C

Question 2

Refer to the exhibit.

A network administrator implemented MPLS LDP changes on PE-A LSR device. The engineer must ensure

there are no LDP peer are fully operational. Which LDP feature must the engineer apply to the existing

configuration to eliminate the problem?

Options :

A :

Configure MPLS LDP IGP synchronization on the network.

B : Configure MPLS LDP NSR for all LDP sessions.

C : Enable LDP session protection under the routing protocol.

D : Disable IP CEF on routers running LDP and enable LDP.

Answer: B

Question 3

Refer to the exhibit.

Which two topology changes happen to the IS-IS routers? (Choose two.)

Options :

A : All four routers are operating as Level 1 routers only.

B : All four routers are operating as Level 2 routers only.

C : R1 and R4 are Level 2 neighbours.

D : R1 and R2 are Level 2 neighbours.

E : All four routers are operating as Level 1-2 routers.

Answer: A,D

Question 4

What is the primary role of a BR router in a 6rd environment?

Options :

A :

It provides connectivity between end devices and the IPv4 network.

B :

It embeds the IPv4 address in the 2002::/16 prefix.

C :

It connects the CE routers with the IPv6 network.

D :

It provides IPv4-in-IPv6 encapsulation

Answer: C

Question 5

Refer to the exhibit. LDP peering between routers R1 and R2 is dropped when the link between R1 and R2 is taken offline. However, LDP peering between R2 and R3 stays up when the link between R2 and R3 is taken offline. Which action allows MPLS traffic forwarding to continue normally if the link between R1 and R2 goes down?

Options :

A : Enable IGP and LDP Synchronization on R1.

B : Implement LDP Session Protection on R1.

C : Enable IGP and LDP Synchronization on R2.

D : Implement LDP Session Protection on R2.
