  A. TRUE

  B. FALSE

  Correct Answer: B

• Question 183:

  A transport tunnel can either use an MPLS or GRE encapsulation.

  A. TRUE B. FALSE

  Correct Answer: A

• Question 184:

  Which of the following statements is FALSE regarding 6VPE?

  A. 6VPE is a tunneling technology that makes use of MPLS tunnels to transport IPv6 information over an IPv4 MPLS infrastructure.

  B. Customers connected to 6VPE could run native IPv6 or IPv4.

  C. On the PE router, the next hop for a VPN IPv6 address is an IPv6 address, regardless of the nature of the network between the PEs.

  D. 6VPE requires an IPv6-aware MPLS core.

  E. Both C and D are false.

  F. All of the above statements are true.

  Correct Answer: D

• Question 185:

  Which of the following statements are FALSE regarding the VPN-IPv4 address family? (Choose two.)

  A. When a PE router receives an IPv4 prefix from its local CE it creates a VPN-IPv4 prefix.

  B. The route distinguisher (RD) is appended to the IPv4 prefix to form a 16 byte VPN-IPv4 prefix.

  C. VPN-IPv4 allows BGP to distinguish multiple routes with the same prefixes originated from distinct customers

  D. VPN-IPv4 addresses are only present within the service provider network.

  E. In VPRN, data traffic is carried in VPN-IPv4 packets.

  Correct Answer: BC

• Question 186:

  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?

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

  B. Only default IPv4 address families are required since the CE is not aware of the VPRN service

  C. Either IPv4 or VPN-IPv4 address families can be configured on the PE-CE BGP session

  D. An IPv4 address family configuration is required for the PE-PE configuration.

  Correct Answer: B

• Question 187:

  Which of the following best describes the label stack for a packet in the VPRN context?

  A. An outer label and a transport label.

  B. An inner label and a service label.

  C. A transport label and a service label.

  D. An MPLS transport label

  Correct Answer: C

• Question 188:

  Which of the following statements about VPRN is NOT true? (Choose two.)

  A. VPRN is an IP service that connects multiple sites in a single routed domain over the provider-managed IP/MPLS network.

  B. Each VPRN consists of a set of customer sites that must connect to the same PE router

  C. In a VPRN service, each customer router becomes a routing peer to other customer routers

  D. VPRN provides customer routers with transparent IP connectivity without knowledge of the MPLS core

  Correct Answer: BC

• Question 189:

  B. A mirror destination listing port 1/1/4.

  C. A remote source command indicating the IP address of the service router he is configuring a local mirror on.

  D. Verification that his IP/MPLS infrastructure is in place

  E. None of the above.

  Correct Answer: B
