Cisco CCDE 400-007 Questions & Answers

• Question 31:

  Company XYZ has implemented policy-based routing in their network. Which potential problem must be kept in mind about network reconvergence and PBR?

  A. It can limit network scalability

  B. It can create microloops during reconvergence

  C. It increases convergence time.

  D. It reduces convergence time.

  Correct Answer: A

  Policy-based routing adds flexibility and control that other routing techniques do not, however. It gives you a level of control that a routing protocol by itself can't accomplish. With flexibility, there is typically a cost, and in this case, it's scalability and manageability.

• Question 32:

  Refer to the exhibit.

  

  There are multiple trees in the Cisco FabricPath All switches in the Layer 2 fabric share the same view of each tree. Which two concepts describe how the multicast traffic is load- balanced across this topology? (Choose two )

  A. A specific (S.G) traffic is not load-balanced

  B. All trees are utilized at the same level of the traffic rate

  C. Every leaf node assigns the specific (S.G) to the same tree.

  D. A specific (S.G) multicast traffic is load-balanced across all trees due to better link utilization efficiency.

  E. The multicast traffic is generally load-balanced across all trees

  Correct Answer: BD

• Question 33:

  A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed Which two of these actions would reduce that delay? (Choose two.)

  A. Increase network stability.

  B. Reduce the time for the network to reconverge.

  C. Increase the notification of interface flaps.

  D. Enable lower data link layer recovery systems to have an opportunity to restore the interface

  Correct Answer: BD

• Question 34:

  A. the ability to have forwarding tables at each device

  B. more flexible configuration per device

  C. more consistent device configuration

  D. programmatic APIs that are available per device
