• Question 33:

  

  You are troubleshooting a problem with a BGP peer where BGP routes are not being accepted from that peer.

  Referring to the exhibit, which two statements are correct? (Choose two.)

  A. Term 0 is missing a terminating action that allows BGP routes to be accepted.

  B. Term 0 is missing a route-filter that specifies the allowed routes.

  C. The reject at the end of the policy is preventing the routes from being accepted.

  D. You cannot have terminating actions outside of terms.

  Correct Answer: AC

• Question 34:

  

  A network administrator is investigating why traffic from R2 is not being forwarded to R1.

  Referring to the show isis database command output shown in the exhibit, what is causing this problem on the network?

  A. R1 and R2 are in different IS-IS areas.

  B. The preferred interface between R1 and R2 is experiencing errors.

  C. R1 is configured to drop all incoming traffic.

  D. R2 is ignoring specific LSPs from R1 in its SPF calculations.

  Correct Answer: D

• Question 35:

  

  Referring to the exhibit, which statement is true?

  A. The BGP session between R1 and R2 will establish correctly and only the inet6 unicast NLRI will pass routing information.

  B. The BGP session between R1 and R2 will fail to establish correctly due to an NLRI mismatch.

  C. The BGP session between R1 and R2 will establish correctly and the inet unicast and the inet6 unicast NLRIs will pass routing information.

  D. The BGP session between R1 and R2 will establish correctly and only the inet unicast NLRI will pass routing information.

  Correct Answer: D

• Question 36:

  You are establishing a Layer 3 VPN between two PE devices. Currently you have a single internal IPv4 BGP peering between the PE devices. You must ensure that the IPv4 and IPv6 routes from both CE devices are exchanged between these sites.

  Which two statements are correct in this scenario? (Choose two.)

  A. You must enable IPv6 tunneling on the LSPs between the PE devices.

  B. You must establish an IPv6 BGP peering between the two PEs.

  C. You must enable the inet6-vpn NLRI on both PE devices.

  D. You must enable the inet-vpn NLRI on both PE devices.

  Correct Answer: CD

• Question 37:

  

  Two CE devices (CE-1 and CE-2) belong to the same customer and connect into a single PE device (PE1). However, the CE devices cannot communicate with each other. You want to allow the CE devices to communicate with each other.

  Referring to the exhibit, which action would solve the problem?

  A. Configure both routing instances with the set routing-options autonomous-system loops 3 statement.

  B. Configure both routing instances with the as-override statement within the BGP protocol.

  C. Configure both routing instances with the vrf-table-label statement.

  D. Configure both routing instances with the set routing-options auto-export statement.

  Correct Answer: D

• Question 38:

  

  You are using EVPN to provide Layer 2 stretched VLANs between two sites. You notice that the MAC addresses in either site are not showing up on the remote site.

  Referring to the exhibit, what are two ways to solve this problem? (Choose two.)

  A. On R1, issue the set switch-options vrf-target target:65101:22030 command.

  B. On R2, issue the delete protocols evpn vni-options vni 22030 command.

  C. On R2, issue the set switch-options vrf-target target:65101:22030 command.

  D. On R1, issue the set protocols evpn vni-options vni 22030 vrf-target target :65101:22030 command.

  Correct Answer: AC

• Question 39:

  

  Referring to the exhibit, you want to reduce the CPU processing load on PE 2 by preventing the receipt of routes belonging to Customer B.

  In this scenario, which layer 3 VPN scaling mechanism provides this functionality?

  A. route refresh

  B. route origin

  C. route reflection

  D. route target filtering

  Correct Answer: D

• Question 40:

  

  You have a Layer 3 VPN established between PE-1 and PE-2 as well as between PE-1 and PE-3. You are using a route reflector (RR-1) to distribute VPN routes to your IBGP peers. You are asked to ensure that only relevant routes are sent from RR-1 to each of the PE routers.

  Referring to the exhibit, which statement is correct?

  A. You should use VRF export policies on RR-1 to control which routes are sent to each PE router.

  B. You should use route target filtering only on RR-1 to control which routes are sent to each PE router.

  C. You should use firewall filtering on RR-1 and all the PE devices to control which routes are sent to each PE router.

  D. You should use route target filtering on RR-1 and all the PE devices to control which routes are sent to each PE router.

  Correct Answer: B
