Cisco CCNP Enterprise 300-410 Questions & Answers

• Question 851:

  What is LDP used for in an LSR?

  A. to allow for a system-wide exchange of labels across MPLS network

  B. to create a label across the PE routers for end-to-end path assignment

  C. to communicate the routes known for a specific interface

  D. to create a database of label bindings that allow for hop-by-hop forwarding

  Correct Answer: D

• Question 852:

  What are the two goals of micro BFD sessions? (Choose two.)

  A. The high bandwidth member link of a link aggregation group must run BFD.

  B. Any member link on a link aggregation group must run BFD.

  C. Continuity for each member link of a link aggregation group must be verified.

  D. Run the BFD session with 3x3 ms hello timer.

  E. Each member link of a link aggregation group must run BFD.

  Correct Answer: CE

  Reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bfd/configuration/xe-16-8/irb-xe-16-8-book/irb-micro-bfd.html

  The goal of micro BFD sessions are:

  -Run BFD session over each LAG member link.

  -Verify link continuity for each member link.

  - Allow BFD to control the LAG member link to be part of the L2 load-balancing table of the LAG interface in the presence or absence of LACP.

• Question 853:

  Which characteristic is representative of a hub-and-spoke topology between PE routers in a Layer 3 MPLS VPN network?

  A. The PE routers use different RDs for each VRF to import and export M-BGP prefixes.

  B. Each PE router uses a different RD to identify all branches.

  C. The PE routers use different RTs to import and export M-BGP prefixes.

  D. The PE routers are configured with multiple VRFs for all branches.

  Correct Answer: C

• Question 854:

  How does MPLS Layer 3 VPN function?

  A. When an EIGRP internal route is redistributed into BGP by one PE and then back into EIGRP by another PE, the originating router ID for the route is changed to the router ID of the first PE.

  B. When a destination PE device receives a labeled packet, it pops the label and uses it to forward the packet to the correct CE device.

  C. When a PE device forwards a packet received from a CE device across the provider network, it labels the packet with the label learned from the source PE device.

  D. When a VPN route is learned from a CE device and injected into IGP, a VPN route distinguisher attribute is associated with it.

  Correct Answer: B
