• Question 631:

  Two LSPs traverse the path R1-R2-R3. Both LSPs are configured with facility fast reroute and link protection. When router R1 is the PLR, which router becomes the Merge Point (MP) for this LSP?

  

  A. Router R1
  B. Router R2
  C. Router R3
  D. Router R4
  E. Router R5
  B. Router R2

• Question 632:

  Two directly connected routers set different interface Hello timeout values. Router R1 uses 15 seconds, while router R2 uses 30 seconds. Which of the following best describes the LDP adjacency?

  A. The adjacency forms with the lower timeout value.
  B. The adjacency forms with the higher timeout value.
  C. The adjacency is in init state.
  D. The adjacency times out after 30 seconds.
  A. The adjacency forms with the lower timeout value.

• Question 633:

  Click on the exhibit button below. Assume the following:

  

  -Each router's OSPF interfaces are in the areas shown.

  -

  Bidirectional LDP-over-RSVP tunnels extend from routers R1 to R3 and back over the path R1-R4-R5-R3.

  -

  You enable fast reroute facility bypass on the R5-R3 RSVP LSP.

  -

  Router R5 acts as a PLR, protecting the R5-R3 link by building a bypass tunnel through router R2.

  You build a layer 2 VPN on routers R1 and R3, using the LDP-over-RSVP tunnels. What MPLS configuration step must you complete on router R2 for it to protect the end-to-end service?

  A. Enable LDP on the R2-R5 interface.
  B. Configure T-LDP sessions between routers R2 and R5 and R3.
  C. Configure LDP-over-RSVP support on router R2.
  D. Enable MPLS and RSVP on the router R2 network interfaces.
  E. Enable LDP on the R2-R5 and R2-R3 interfaces.
  D. Enable MPLS and RSVP on the router R2 network interfaces.

• Question 634:

  Which of the following regarding per-platform label space is TRUE?

  A. A separate label is used for each interface on which the FEC is advertised.
  B. A single label is assigned to a FEC for all interfaces on the same router,
  C. It is typically used when the device has ATM or Frame Relay interfaces.
  D. It uses more label resources than a per-interface label space.
  B. A single label is assigned to a FEC for all interfaces on the same router,

• Question 635:

  C. LDP

• Question 636:

  What is the purpose of service mirroring on the Alcatel-Lucent Service Router?

  A. To mirror service requirements of a customer with a single branch office and multiple remote sites
  B. To utilize unused ports of a service router until they are required for a service.
  C. To replicate traffic from a service port to another port for debugging or monitoring functions
  D. To ease the configuration burden of services that support a large number of subscribers
  E. All of the above
  C. To replicate traffic from a service port to another port for debugging or monitoring functions

• Question 637:

  Which of the following about Type 4 LSAs is FALSE?

  A. A Type 4 LSA is not generated in a single area AS.
  B. A Type 4 LSA is generated by the ABRs of the area that contains the ASBR.
  C. A Type 4 LSA advertises the external networks connected to the ASBR.
  D. A Type 4 LSA is not flooded in the area that contains the ASBR.
  C. A Type 4 LSA advertises the external networks connected to the ASBR.

• Question 638:

  D. Hashing used to select the egress label.
  E. Export policy applied to advertise multiple labels for a given FEC.
  A. Liberal label retention mode
  C. ECMP enabled in the config>router context.
  E. Export policy applied to advertise multiple labels for a given FEC.

• Question 639:

  Which of the following statements regarding admin groups is FALSE?

  A. Admin groups can be configured using the command "configure>router>mpls>admin- group".
  B. CSPF uses the information defined by admin groups when paths are computed for constraint-based LSPs.
  C. By default, interfaces for which MPLS has been enabled are in the default admin group.
  D. A LSP can make use of admin groups for constraint-based path calculations by including or excluding the admin group
  C. By default, interfaces for which MPLS has been enabled are in the default admin group.

• Question 640:

  Click the exhibit button.

  

  Router 2 advertises the network 192.168.3.0/24 to router R1 via IS-IS. How can router R1 ensure that it discards the route?

  A. Use a prefix list on router R1 to discard all ingress IS-IS routes.
  B. Use an export policy and prefix list on router R1.
  C. Use an import policy and a prefix list on router R1.
  D. This is not possible because IS-IS cannot use import policies.
  D. This is not possible because IS-IS cannot use import policies.
