Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q46-Q51):

NEW QUESTION # 46

Click the Exhibit button.
Referring to the exhibit, the PE-to-CE protocol being used is OSPF for the L3VPN. Also, there is an OSPF neighborship between CE-1 and CE-2.
Which statement is correct in this situation?

  • A. Hosts at Site-1 will reach hosts at Site-2 through the CE-1 and CE-2 link by default.
  • B. You must set a high metric on the CE-1 to CE-2 link for hosts at Site-1 to use the L3VPN to reach hosts at Site-2.
  • C. Hosts at Site-1 will reach hosts at Site-2 through the L3VPN by default.
  • D. You must set a high metric on the CE-1 to PE-1 link for hosts at Site-1 to use the CE-1 to CE-2 link to reach hosts at Site-2.

Answer: A

Explanation:
In the exhibit, the PE-to-CE protocol used is OSPF, and there is an OSPF neighborship between CE-1 and CE-2 within the same Area 0. Let's analyze the default OSPF routing behavior in this setup to determine the correct statement.
1. **OSPF Neighborship**:
- CE-1 and CE-2 have an OSPF neighborship directly within Area 0.
- OSPF prefers intra-area routes over inter-area and external routes.
2. **Default Routing Behavior**:
- Since CE-1 and CE-2 are directly connected through an OSPF link within the same area, OSPF will prefer this direct intra-area path over any other paths learned via the PE routers and the L3VPN.
- This is because intra-area routes have a lower metric compared to inter-area or external routes.
3. **Metric Considerations**:
- By default, OSPF will route traffic between Site-1 and Site-2 through the direct link between CE-1 and CE-2, unless the link's metric is artificially increased to make it less preferable.
- There is no need to adjust metrics for the CE-1 to PE-1 link to prefer the CE-1 to CE-2 path, as OSPF already prefers direct intra-area paths.
**Conclusion**:
Given the default behavior of OSPF and the topology shown in the exhibit, the correct statement is:
**B. Hosts at Site-1 will reach hosts at Site-2 through the CE-1 and CE-2 link by default.**

NEW QUESTION # 47
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 only supports Ethernet interfaces when connecting to CE devices.
  • B. This type of VPN requires the support of the inet-vpn NLRI on all core BGP devices
  • C. You must use the same route-distinguiaher value on both PE devices.
  • D. You must assign a unique site number to each attached site's configuration.

Answer: B

Explanation:
BGP signaled Layer 2 VPN is a type of VPN that uses BGP to distribute VPN labels and information for Layer 2 connectivity between sites over an MPLS network. BGP signaled Layer 2 VPN requires the support of the l2vpn NLRI on all core BGP devices1. The l2vpn NLRI is a new address family that carries Layer 2 VPN information such as the VPN identifier, the attachment circuit identifier, and the route distinguisher. The l2vpn NLRI is used for both auto-discovery and signaling of Layer 2 VPNs2. In this scenario, we are configuring a BGP signaled Layer 2 VPN across an MPLS enabled core network. Therefore, we need to ensure that all core BGP devices support the l2vpn NLRI.

NEW QUESTION # 48
Which statement is correct about IS-IS when it performs the Dijkstra algorithm?

  • A. The algorithm will stop processing once the tree database is empty.
  • B. Tuples with the lowest cost are moved from the tree database to the LSDB.
  • C. When a new neighbor ID in the tree database matches a router ID in the LSDthe neighbor ID is moved to the candidate database.
  • D. The local router moves its own local tuples into the candidate database.

Answer: A


NEW QUESTION # 49
Which two statements are correct about VPLS tunnels? (Choose two.)

  • A. LDP-signaled VPLS tunnels only support control bit 0.
  • B. LDP-signaled VPLS tunnels use auto-discovery to provision sites
  • C. BGP-signaled VPLS tunnels require manual provisioning of sites.
  • D. BGP-signaled VPLS tunnels can use either RSVP or LDP between the PE routers.

Answer: A,D

NEW QUESTION # 50
Exhibit

You are running a service provider network and must transport a customer's IPv6 traffic across your IPv4- based MPLS network using BGP You have already configured mpis ipv6-tunneling on your PE routers.
Which two statements are correct about the BGP configuration in this scenario? (Choose two.)

  • A. You must configure family inet6 labeled-unicast between PE routers.
  • B. You must configure family inet6 unicast between PE routers.
  • C. You must configure family inet6 add-path between PE and CE routers.
  • D. You must configure family inet6 unicast between PE and CE routers.

Answer: A,D

Explanation:
To transport IPv6 traffic over an IPv4-based MPLS network using BGP, you need to configure two address families: family inet6 labeled-unicast and family inet6 unicast. The former is used to exchange IPv6 routes with MPLS labels between PE routers, and the latter is used to exchange IPv6 routes without labels between PE and CE routers. The mpis ipv6-tunneling command enables the PE routers to encapsulate the IPv6 packets with an MPLS label stack and an IPv4 header before sending them over the MPLS network.
