• Question 155:

  A service provider NOC engineer received numerous support tickets from their VPN customers. These customers are reporting packet loss between two PE routers. The NOC engineer created a VRF TEMP to run tests between these two PE

  Which test can quickly identify the core link that is causing the problems?

  A. an extended traceroute with multipath option between the PE's loopbacks
  B. anmpls traceroute with multipath option between the PE's loopbacks
  C. anmpls ping with sweep option between the PE's loopbacks
  D. avrf ping between customer's CE router and service provider's remote PE router
  E. an extended ping with sweep option between the PE's loopbacks
  F. avrf traceroute between customer's CE router and service provider's remote PE router
  B. anmpls traceroute with multipath option between the PE's loopbacks

• Question 156:

  A network engineer deployed Cisco MPLS TE tunnels on the service provider network to steer the traffic over those tunnels to optimize the bandwidth utilization. Which two configurations can send the traffic to the Cisco MPLS TE tunnel interfaces? (Choose two.)

  A. applying the fast-reroute per-prefix command
  B. static route pointing down to the Cisco MPLS TE interface tunnel
  C. applying the autoroute announce command under the Cisco MPLS TE interface tunnel
  D. enabling LFA calculation
  E. applying an explicit-path command under the Cisco MPLS TE interface tunnel
  C. applying the autoroute announce command under the Cisco MPLS TE interface tunnel
  E. applying an explicit-path command under the Cisco MPLS TE interface tunnel

• Question 157:

• Question 158:

  Which statement about the requirements of eBGP multipath is true?

  A. The path should be learned from an external or confederation-external neighbor.
  B. The path should be learned from an internal neighbor.
  C. The IGP metric to the BGP next hop should be equal to the best-path IGP metric, unless the router is configured for unequal-cost iBGP multipath.
  D. The path should be learned from an IGP protocol.
  A. The path should be learned from an external or confederation-external neighbor.

• Question 159:

  Which of the following descriptions about uRPF loose mode is correct? (Choose two).

  A. It is typically used on point-to-point interfaces where the same interface is used for both directions of packet flows; if the source address has a return route in the FIB table, it is then checked against the adjacency table to ensure the same interface receiving the packet is the same interface used for the return path
  B. If a packet fails the uRPF loose mode check, the packet is then transmitted and creates a log message
  C. It is typically used on multipoint interfaces or on routers where asymmetrical routing is used (packets are received on one interface but the return path is not on the same interface); loose mode verifies a source address by looking in forwarding information base(FIB).
  D. If a packet fails the uRPF loose mode check, the packet is then dropped
  C. It is typically used on multipoint interfaces or on routers where asymmetrical routing is used (packets are received on one interface but the return path is not on the same interface); loose mode verifies a source address by looking in forwarding information base(FIB).
  D. If a packet fails the uRPF loose mode check, the packet is then dropped
