• Question 25:

  You are working at a large service provider supporting the core MPLS network. You have determined that a line card in one of the core routers has failed. Which two steps should you take before requesting that a technician be dispatched to the location to replace the card? (Choose two.)

  A. Reboot the router.

• Question 26:

  You are working as a Tier 3 NOC engineer at a large service provider. Supporting the core network is part of your job responsibility. An escalation has come to you after Tier 2 determines that a problem lies within the core of the network and is affecting every customer. You have analyzed the information in the trouble ticket, performed your own troubleshooting, and have determined that a BGP session is flapping between two core routers. Which two steps should you take before escalating to the router vendor? (Choose two.)

  A. Verify that the routers are sending keepalives.
  B. Determine if there is a Layer 2 or 3 transport problem.
  C. Enable path MTU discovery.
  D. Restart the BGP router process.
  A. Verify that the routers are sending keepalives.
  B. Determine if there is a Layer 2 or 3 transport problem.

• Question 27:

  A network operations engineer of company ABC is responsible for the operations and maintenance aspects of the MPLS backbone. The MPLS backbone is built by using MPLS- capable routers that are connected with Gigabit Ethernet and POS interfaces. A complaint was received about the lack of connectivity between two sites of the end customer of the ABC company. This customer relies on the availability of the MPLS label-switched path that is provided by the backbone network of company ABC. The operations engineer quickly determined that the MPLS label entries for certain prefixes provided by LDP were missing on one of the provider edge routers that connected to the customer router. The operations engineer also determined that the LDP session of the PE router was down with some of its neighbors in the backbone.

  Which three of the following statements represent valid considerations for further troubleshooting? (Choose three.)

  A. A Layer 1 or 2 connectivity problem might be causing LDP to be unable to discover link-local peers.
  B. The MPLS label-switched path ping to the LDP router ID of the peer will be helpful to determine the issue with LDP.
  C. A ping that is using the PE's own transport address as source might help to determine if the LDP transport addresses of the peers are unreachable.
  D. Interface label space might be incorrectly configured, or the router might be unable to allocate the interface label.
  E. There could be a password mismatch between the LDP neighbors. Logging messages might uncover a message that is related to password mismatch.
  F. A fault or a misconfiguration on the backbone in the downstream direction might be causing label retention problems.
  A. A Layer 1 or 2 connectivity problem might be causing LDP to be unable to discover link-local peers.
  C. A ping that is using the PE's own transport address as source might help to determine if the LDP transport addresses of the peers are unreachable.
  E. There could be a password mismatch between the LDP neighbors. Logging messages might uncover a message that is related to password mismatch.

• Question 28:

  You are responsible for the network of a content provider. The content provider uses ISP-A and ISP-B for Internet transit service for the purpose of redundancy and load balancing. The content provider has one address range assigned to it. Which two of the following techniques are more effective to achieve load balancing and redundancy for inbound traffic? (Choose two.)

  A. Use the MED feature.
  B. Use the local-preference feature.
  C. Split the address range of the content provider into more specific prefixes.
  D. Use the AS-prepend feature.
  E. Use ISP-A for outbound traffic and ISP-B for inbound traffic.
  F. Aggregate the prefixes that are received from ISP-A and ISP-B into a less-specific prefix.
  C. Split the address range of the content provider into more specific prefixes.
  D. Use the AS-prepend feature.

• Question 29:

  Refer to the exhibit.

  

  The network diagram shows a video service provider. The IPTV video source is connected to R1, whereas the clients are connected to R6. Traffic flows from R1 to R6 both as unicast as well as multicast. Unicast traffic load is greater than multicast by several orders of magnitude. There are two paths from R1 to R6, each of them traverses through the R3 router. The path R1-R2-R3- R6 has a lower OSPF cost path compared to R1-R5-R4-R3-R6. The service provider took into account several design criteria and implemented TE tunnels with forwarding adjacency between R1 and R3 both from the perspective of load sharing as well as for fast reroute. Bringing up TE tunnels had the affect of dropping multicast traffic at the R3 router. On troubleshooting the issue, you noticed that the OSPF route to the source of multicast traffic was being learned over the TE tunnel, and this has caused the RPF check to fail.

  Considering this problem, what are two solutions to prevent multicast traffic from being affected by the RPF check failing due to the TE tunnel? (Choose two.)

  A. Use multitopology routing if the software supports it.
  B. Create a static mroute on R3 with the RPF pointing to the TE tunnel.
  C. Use multicast-intact with forwarding adjacency.
  D. Enable PIM on the TE tunnel on both of the headend routers.
  E. Enable on the core facing links a new routing protocol such as another OSPF process or ISIS.
  F. Configure the TE tunnel to use autoroute announce as opposed to forwarding adjacency, and circumvent the RPF problem by using the multicast-intact command.
  A. Use multitopology routing if the software supports it.
  F. Configure the TE tunnel to use autoroute announce as opposed to forwarding adjacency, and circumvent the RPF problem by using the multicast-intact command.
