Question 1

Which of the following statements are TRUE about configuring a SDP between an IES and a VPLS? (Choose 2)

AThe SDP must be a mesh

BThe SDP must be a spoke.

COnce the SDP is configured on both PE routers, both the services will be operationally up without further configuration changes.

DThe Layer 2 MTUs must match between the IES and the VPLS

EThe Layer 2 MTU must be 14 bytes smaller on the VPLS than it is on the IES.

Answer : B, D

Question 2

An operator needs to provision 6VPE on a 7750 SR that is also used to provide existing IPv4 VPRN services. IPv6 VPRN customers use BGP as a PE-CE protocol. Which of the following statements is FALSE regarding the configuration steps required?

AMP-BGP sessions need to be configured in the service provider network to support a VPN-IPv6 address family.

BPE routers must be configured to run MP-BGP and IPv6

CPE-to-CE BGP sessions need to be configured to support IPv6.

DThe provider core must be configured to support IPv6

ENone of the above statements are false.

FAll of the above statements are false

Answer : B

Topic 2, Volume B

Question 3

When using MP-BGP for an IPv4 VPRN service, what address family needs to be used for a PE-CE BGP session?

AThe VPN-IPv4 address family.

BThe IPv4 address family.

CEither IPv4 or VPN-IPv4 address families can be configured.

DThe same address family must be used for the provider network and the PE-CE.

Answer : B

Question 4

What is the minimum Ethernet physical network MTU required for a Layer 2 service on an MPLS encapsulated SDP with a service MTU of 1518?

A1520

B1540

C1548

D1556

Answer : B

Question 5

Why must the MTU be changed when configuring an IES spoke termination to a VPLS?

AThe default service MTU on a VPLS service is 1514 bytes.

BThe default IP MTU of an IES is set based on the network port MTU.

CDuring VC label signaling, the VC MTU is verified and must match.

DAll of the above.

Answer : D

Question 6

A VPRN service is configured with BGP used as the CE-PE routing protocol. What address families are required on the PE-CE BGP session?

AVPN-IPv4 address families are required in order for routes to be exchanged with the PE.

BOnly default IPv4 address families are required since the CE is not aware of the VPRN service

CEither IPv4 or VPN-IPv4 address families can be configured on the PE-CE BGP session

DAn IPv4 address family configuration is required for the PE-PE configuration.

Answer : B
