• Question 4:

  VPRN 300 is configured between Node 3 and Node 4. Node 4 receives VPN routes from Node 3 and imports them into the VRF. The entire route-table is displayed below for VPRN 300 on Node

  4. When attempting a ping from VPRN 300 on Node 4 to 30.1.1.1 the ping fails. A ping from Node 3 within VPRN 300 to 30.1.1.1 is successful. What is the cause of the problem?

  

  A. No local interface existed in VPRN 300 route-table on Node 4

  B. Syntax problem in the ping command

  C. Prefix 30.1.1.1 does not exist on the far-end

  D. Source address has to be specified in the ping command

  A. Type external has to be configured on Node 2 under group vrf

  B. Autonomous-system has to be configured on Node 4 under vprn 300

  C. Router-id has to be configured on Node 4 under vprn 300

  D. Router-id has to be added under BGP on Node 2

  E. EBGP will not work under VPRN

  Correct Answer: B

• Question 7:

  VPRN 300 is confiugred on Node 3 and Node 4 with LDP as the transport. No VPN routes are exchanged between Node 3 and Node 4. What is the cause of the problem?

  

  

  A. VRF policy configured on Node 3 does not match with vrf-target configured on Node 4

  B. No SDP defined in the VPRN configuration on both nodes

  C. VRF-target mismatch on Node 3 and Node 4

  D. Route-distinguisher mismatch on Node 3 and Node 4

  E. Encapsulation type mismatch on SAPs on Node 3 and Node 4

  Correct Answer: A

• Question 8:

  Node 1 receives some VPRN routes from Node 2, but Node 2 is not receiveing any VPRN routes from Node 1. Routes in VPRN 400 route table are found on Node 1 as follows: Based on the configuration below, why is Node 2 not receiving BGP VPN routes from Node 1?

  

  

  A. VRF import and export policies defined on Node 1 do not match with vrf-target defined on Node 2

  B. Prefix-list exportVPRN100 is applied on Node 1 but not on Node 2

  C. More than one import route targets are defined on Node 1 and only one defined on Node 2

  D. VRF target has to be defined on Node 1 as well

  E. Community target:65535:101 is not defined on Node 1

  Correct Answer: E

• Question 9:
