Juniper JNCIP-SP JN0-663 Questions & Answers

• Question 11:

  You recently deployed CoS-based forwarding in your network, which uses OSPF as its IGP. You notice that the forwarding of traffic has not changed and is not following the path indicated within your configuration.

  In this scenario, which statement explains this behavior?

  A. The defined policy references IP addresses as the next-hops instead of interface names.

  B. Load balancing has not been enabled under [edit forwarding-options].

  C. The defined policy references interface names as the next-hops instead of IP addresses.

  D. The defined policy has not been applied under [edit class-of-service forwarding-policy].

  Correct Answer: C

• Question 12:

  You are creating a new LDP signaled Layer 2 circuit between three customer sites.

  In this scenario, which two statements are correct? (Choose two.)

  A. BGP is used to exchange the virtual circuit labels with other PEs.

  B. You are allowed to tunnel your LDP sessions through RSVP LSPs.

  C. You are not allowed to use any RSVP-signaled LSPs in your core network.

  D. LDP is used to exchange the virtual circuit labels with other PEs.

  Correct Answer: BD

• Question 13:

  Which two statements regarding ingress replication in EVPN are correct? (Choose two.)

  A. Ingress replication labels are learned from remote PEs through the EVPN Type-3 route.

  B. Ingress replication relies on PIM to build the multicast replication tree.

  C. Ingress replication is only supported in vrf-type routing instances.

  D. Ingress replication will replicate all BUM traffic to all remote PEs in the EVI.

  Correct Answer: AD

• Question 14:

  

  The exhibit shows a BGP peering session for two PE routers. The BGP session is up, but the hosts in the Layer 2 VPN that uses the BGP session are unable to communicate.

  What is the problem in this situation?

  A. The BGP peer does not support the add-path feature.

  B. There is a mismatch in the supported NLRI address families between the BGP peers.

  C. The local BGP router does not support Layer 2 VPN and Layer 3 VPN NLRI address families at the same time.

  D. The BGP peer does not support the restarter functionality.

  Correct Answer: B

• Question 15:

  Which two statements are true about what a route reflector does by default when distributing routes it has received from reflector clients? (Choose two.)

  A. It does not change any received BGP attributes.

  B. It changes the default BGP attributes to inform peers that it is a route reflector.

  C. It sets the next hop of all routes to "self" to prevent routing loops.

  D. It adds its cluster ID to the client-received routes.

  Correct Answer: AD

• Question 16:

  You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network.

  In this scenario, which statement is correct?

  A. This type of VPN is only supported over LSPs that are using traffic-engineering.

  B. You must use a unique route distinguisher value on all PE devices in your environment.

  C. You must ensure that all interfaces within the site's configuration are explicitly defined with their remote site identifier values.

  D. This type of VPN requires the support of the 12vpn signaling NLRI on all route reflectors and participating PE devices.

  Correct Answer: D

• Question 17:

  

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

  A. This router is an ASBR.

  B. There are two interfaces marked as passive.

  C. There is one interface marked as passive.

  D. This router is an ABR.

  Correct Answer: AC

• Question 18:

  A customer recently migrated to IS-IS and is concerned about resource starvation when the routing protocol daemon (RPD) starts.

  To resolve this issue and protect R2 and R3, which feature should you implement?

  A. Double the policy-options damping half-life timer to let the network settle.

  B. Implement the overload bit and timer to signal service availability.

  C. Deploy firewall filters to limit the prefix count in the route table.

  D. Use the forwarding-options ip-options-protocol-queue parameter to increase resources.

  Correct Answer: B

• Question 19:

  

  Referring to the exhibit, you want to make ISP1 your preferred connection for inbound and outbound traffic.

  Which two steps will accomplish this task? (Choose two.)

  A. Create an export policy setting local-preference 200 and next-hop self and apply it to the IBGP peers on R2.

  B. Create an export policy to prepend the ASN on advertised routes and apply it to the EBGP peer on R1.

  C. Create an export policy to prepend the ASN on advertised routes and apply it to the EBGP peer on R2.

  D. Create an export policy setting local-preference 200 and next-hop self and apply it to the IBGP peers on R1.

  Correct Answer: CD

• Question 20:

  

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

  A. The route-distinguisher configuration allows routes to be shared between CE-1 and CE-2.

  B. The vrf-target configuration stops routes from being shared between CE-1 and CE-2.

  C. The route-distinguisher configuration stops routes from being shared between CE-1 and CE-2.

  D. The vrf-target configuration allows routes to be shared between CE-1 and CE-2.

  Correct Answer: AB
