  D. The routing policies are implemented in a sequential manner.
  E. The routing policies are implemented using route maps.
  C. You can change an existing routing policy by editing individual statements.
  D. The routing policies are implemented in a sequential manner.

• Question 15:

  Refer to the exhibit A. Configure R3 in a new area

  

  Reuters R2. R3, R4 and R5 all reside in the same area, with R1 in a different area R3 is overutilized and the engineer wants to reduce its CPU load

  The engineer configured router R4 to summarize routes that it receives from R5. but R3 is still receiving all of the R5 routes.

  Which action resolves the issue?

  B. Configure R2 as a Level 1 router

  C. Configure the summary routes on R5

  D. Configure R4 as a Level I-Level 2 router

  Correct Answer. A
  A

• Question 16:

  Refer to the exhibit.

  

  R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?

  A. The BGP session does not come up between R1 and R2 and between R1 and R3.
  B. The BGP session comes up between R1 and R2 and between R1 and R3.
  C. The BGP session comes up between R1 and R3, but not between R1 and R2.
  D. The BGP session comes up between R1 and R2, but not between R1 and R3.
  B. The BGP session comes up between R1 and R2 and between R1 and R3.

• Question 17:

  Refer to the exhibit.

  

  After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4.

  When the link from R2 is shut down as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via

  R2.

  Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

  A. Configure two OSPF processes on R2 and R3 and redistribute traffic between them.
  B. Redistribute routes from BGP to OSPF as type El.
  C. Use multiarea adjacency to extend Area 10 to the link between R2 and R3.
  D. Create a virtual channel from R3 to R4.
  B. Redistribute routes from BGP to OSPF as type El.

• Question 18:

  Refer to the exhibit.

  

  While applying the configurations on two routers, an engineer notices that OSPF adjacency between them remains down. Through the ping test, the engineer confirmed that both the routers have Layer 3 reachability between them. Which action should the engineer take to make the adjacencies to full?

  A. Enable OSPF just inside the router OSPF process, not in the interfaces of any router
  B. Delete the area 0 authentication message-digest command from the OSPF process in R1
  C. Enter the command ip ospf authentication in R2 interface
  D. Delete the area 0 authentication message-digest command from the OSPF process in R2
  C. Enter the command ip ospf authentication in R2 interface

• Question 19:

  After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?

  A. commit the configuration
  B. roll back the configuration
  C. save the running configuration
  D. merge the configuration
  A. commit the configuration

• Question 20:

  Refer to the exhibit.

  

  Company X is multihomed to a service provider. With the default settings, the link between PE2 and CE1 is the primary link, but Company X has asked for the link between PE4 and CE2 to operate as the primary instead. A network engineer

  used a route-map with local-preference to manipulate the routes from PE2 to CE1 to be less desirable and applied the route-map on PE2 outbound to CE1. However, the path from PE2 to CE1 is still preferred.

  Which action must the engineer take so that the desired path is chosen?

  A. Apply local-preference on PE2 outbound to CE2 with a value less than 100.
  B. Configure the AS-path prepend attribute to increase the number of hops between CE2 and PE4.
  C. Configure the weight attribute on PE2 in the outbound direction to CE2 with a value less than 65,535.
  D. Apply MED in the outbound direction on PE2 to CE1 with a cost lower than the path from PE4 to CE2.
  B. Configure the AS-path prepend attribute to increase the number of hops between CE2 and PE4.
