Questions # 41:

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?

Options:

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

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

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

The provider core must be configured to support IPv6

None of the above statements are false.

All of the above statements are false

Answer

Questions # 42:

Which of the following statements are TRUE regarding a fully meshed VPLS service with a default setting? (Choose 3)

Options:

The vc-id on the mesh-sdp must be explicitly configured.

The vc-id on the mesh-sdp is automatically assigned by a PE using the service id.

The VPLS service id, on all PE routers, does not have to match.

The VPLS service id, on all PE routers, must match.

If dynamic signaling is required, the signaling on all PE routers must be set to TLDP in the configuration of the SDPs.

The signaling on all PE routers will default to TLDP in the configuration of the SDPs; therefore, no configuration change is required for dynamic signaling.

Answer

A, D, F

Questions # 43:

Which of the following statements best describes the purpose of an MP-BGP in a VPRN?

Options:

Routes from different customers with the same IPv4 address prefix are treated as equivalents by MP-BGP.

Alcatel-Lucent 7750 SR routers support MP-BGP for VPN label signaling in a VPRN service only if LDP is used for LSP signaling.

The multi-protocol nature of MP-BGP allows VPRN routes to be distributed within the provider core network as IPv4 routes.

MP-BGP is an enhanced version of BGP that can carry a service label, a tranpot label, and customer route prefixes.

None of the above statements describe the use of an MP-BGP in a VPRN.

All of the above statements describe the use of an MP-BGP in a VPRN.

Answer

Questions # 44:

Which of the following encapsulation types on an Ethernet port support the provisioning of multiple SAPs? (Choose 2)

Options:

Dot1Q

Q-in-Q

ATM

NULL

Nil

Answer

A, B

Questions # 45:

Which of the following represents a SAP on a physical port configured with Q-in-Q encapsulation?

Options:

sap 1/1/1

sap 1/1/1:5

sap 1/1/1:5:5

sap 1/1/1:10.100

Answer

Questions # 46:

Which of the following statements is NOT a valid reason to use MP-BGP as a routing protocol to transport VPRN routes?

Options:

The number of VPRN routes can become very large. MP-BGP can support a very large number of routes.

MP-BGP can carry routing information for a number of different address families.

MP-BGP is designed to exchange information between routers that are not directly connected. This feature keeps VPRN routing information out of P-routers.

MP-BGP can carry additional information attached to a route as an optional BGP attribute.

All of the above statements are valid reasons for using MP-BGP as a VPRN routing protocol.

Answer

Questions # 47:

Which of the following commands is used to configure the encapsulation type of an Ethernet port?
