Which of the following are required for an operational mesh-sdp binding for bidirectional traffic when signaling is enabled within the SDP? (Choose 3)

• LDP must be enabled.
• RSVP must be enabled.
• An SDP must be configured on the far-end.
• Service MTU must match.
• SDP ID must match.

Which of the following statements about the VC-ID is false?

• The vc-id is signaled in the control plane.
• The vc-id is part of the data plane encapsulation.
• There is a vc-id to vc-label mapping.
• The vc-id has point to point significance.

Which of the following statements are true regarding P devices in an MPLS VPRN? (Choose two.)

• Participate in service provider core routing
• P devices are not required to be MPLS enabled. MPLS is only required on the PE devices
• Run a common routing protocol with the CE router
• Must support MP-BGP
• Do not have any connections to the CE
• Must be aware of the VPRNs

An autonomous system has 7 routers configured with BGP. How many iBGP sessions are required for a fully meshed configuration?

• 7
• 13
• 21
• 42

One of the shortcomings of Spanning Tree Protocol (STP) is that it computes a valid, but not necessarily optimal, path between nodes within a network.

• TRUE
• FALSE

What kind of attribute is the aggregator?

• Well-known mandatory
• Well-known discretionary
• Optional transitive
• Optional non-transitive

Which of the following about BGP loops in a VPRN environment is FALSE?

• Traditional BGP loop detection mechanisms may detect a loop in the VPRN scenario, which in fact is not present.
• The Alcatel-Lucent 7750 SR accepts routes containing AS_PATH loops by default.
• When the CLI command 'config>router>bgp# loop-detect discard-route' is used, the Alcatel-Lucent 7750 SR sends a notification to the remote peer and drops the BGP session.
• In VPRN implementations where the CE-PE protocol is BGP, it is possible for separate sites of the same customer to use the same BGP autonomous system number.

A CE hub and spoke VPRN has two spoke sites; which of the following would be the best option to implement this topology at the hub site PE?

• One VPRN, one route distinguisher, and two route targets
• Two VPRNs, one route distinguisher, and three route targets
• Two VPRNs, two route distinguishers, and three route targets
• One VPRN, two route distinguishers, and three route targets

Which of the following regarding route reflectors is TRUE?

• Only the route reflector is configured with a cluster id.
• There can only be one route reflector in a cluster.
• Clients should have iBGP sessions with each other to maintain the mesh.
• There can only be one level of route reflectors in the topology.

During the process of troubleshooting a VPLS problem the 'oam mac-purge' command with 'register' option was used to purge a MAC address from the FDB. Which of the following statements is true?

• Relearning of the MAC address that was purged can only be done once customer traffic resumes.
• Relearning of the MAC address that was purged can only be done with the 'oam mac-populate' command.
• Customer traffic destined to the MAC address that was purged will be dropped until the MAC address is relearned with the 'oam mac-populate' command.
• Relearning of the MAC address that was purged can only be done with the 'oam mac-register' command.
