  R1 and R4 are providing a VPRN for the CEs. Which of the following about the traceroute run on router R5 is TRUE?

  A. The traceroute will only show one hop: R5-R6.

  B. The traceroute will only show 2 hops; R5-R1 and R4-R6.

  C. The traceroute will only show 3 hops: R5-R1, R1-R4 and R4-R6.

  D. The traceroute will show one hop for each router in the provider core and one for each CE-PE hop.

  Correct Answer: C

• Question 112:

  On the Nokia 7750 SR, which of the following statements about MP-BGP used for a VPRN is TRUE?

  A. Routes from different customers with the same IPv4 address prefix are treated as equivalent by MPBGP.

  B. MP-BGP will advertise routes to other BGP sessions on the same PE without the need of policies.

  C. The multi-protocol nature of MP-BGP allows VPRN routes to be converted into IPv4 routes in the provider core network.

  D. MP-BGP is an enhanced version of BGP that can carry customer route prefixes for multiple VPRNs.

  Correct Answer: D

• Question 113:

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

  A. The VPN-IPv4 address family.

  B. The IPv4 address family.

  C. Either IPv4 or VPN-IPv4 address families can be configured.

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

  Correct Answer: B

• Question 114:

  Which of the following about IES is FALSE?

  A. An IES has a configurable VC MTU.

  B. An IES interface has an IP address assigned to it.

  C. IES supports QoS.

  D. An IES requires a spoke SDP.

  Correct Answer: D

  Assuming CE1 exports its system address using BGP, is a routing policy required on PE1 to advertise CE1's system address to PE2?

  A. Yes. A routing policy is required to advertise routes between PE routers in a VPRN regardless of the CE-PE routing.

  B. Yes. A routing policy is required in this case because BGP is used as the PE-CE routing protocol.

  C. No, a routing policy is not required. By default, the Nokia 7750 SR will advertise all VPRN routes between PE routers.

  D. No, a routing policy is not required on PE1, but an import policy is required on PE2.

  Correct Answer: C

• Question 116:

  This output is from a router that is part of a 6VPE deployment using a VPRN. Which type of router would this configuration be found on?

  A. A CE router.

  B. A P router.

  C. A PE router.

  D. Both P and PE routers.

  Correct Answer: A

• Question 117:

  On a Nokia 7750 SR, why must the MTU be explicitly set when configuring an IES spoke termination to a VPLS?

  A. By default, a VPLS signals an MTU based on the network port.

  B. By default, an IES sets its ip-mtu to the VC MTU of the VPLS.

  C. By default, an IES uses an MTU value based on its SAP.

  D. By default, an IES uses an MTU based on the network port.

  Correct Answer: D

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 119:

  On a Nokia 7750 SR, which of the following about IES interfaces is FALSE?

  A. An IES can only have one interface.

  B. An IES interface can have an SDP or a SAP.

  C. An IES can perform fragmentation.

  D. An IES must have an IP address assigned to it.

  Correct Answer: A

• Question 120:

  Which of the following about VPRN route targets is FALSE?

  A. They are used to identify the VRF table for a prefix at the receiving PE.

  B. They are used by VPRNs to control the distribution of VPN routing information.

  C. They are distributed to all PEs and CEs that are part of the VPRN.

  D. They are distributed to PEs to identify the VRF table that a VPN-IPv4 prefix is associated with.

  Correct Answer: C
