Which two statements are correct about reflecting inet-vpn unicast prefixes in BGP route reflection? (Choose two.)

• Route reflectors do not change any existing BGP attributes by default when advertising routes.
• A BGP peer does not require any configuration changes to become a route reflector client.
• Clients add their originator ID when advertising routes to their route reflector
• Route reflectors add their cluster ID to the AS path when readvertising client routes.

In which two ways does OSPF prevent routing loops in multi-area networks? (Choose two.)

• All areas are required to connect as a full mesh.
• The LFA algorithm prunes all looped paths within an area.
• All areas are required to connect to area 0.
• The SPF algorithm prunes looped paths within an area.

Which two statements are correct about VPLS tunnels? (Choose two.)

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

Your organization manages a Layer 3 VPN for multiple customers To support advanced route than one BGP community on advertised VPN routes to remote PE routers.Which routing-instance configuration parameter would support this requirement?

• vrf-export
• vrf-import
• vrf-target export
• vrf-target import

After a recent power outage, your manager asks you to investigate ways to automatically reduce the impact caused by suboptimal routing in your OSPF and OSPFv3 network after devices reboot.Which three configuration statements accomplish this task? (Choose three.)

• set protocols ospf overload timeout 900
• set protocols ospf3 realm ipv4-unicast overload timeout 900
• set protocols ospf overload
• set protocols oapf3 overload timeout 900
• set protocols ospf3 overload

Which two statements describe PIM-SM? (Choose two)

• Routers with receivers send join messages to their upstream neighbors.
• Routers without receivers must periodically prune themselves from the SPT.
• Traffic is initially flooded to all routers and an S,G is maintained for each group
• Traffic is only forwarded to routers that request to join the distribution tree.

Which statement is correct about IS-IS when it performs the Dijkstra algorithm?

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

You are a network architect for a service provider and want to offer Layer 2 services to your customers You want to use EVPN for Layer 2 services in your existing MPLS network.Which two statements are correct in this scenario? (Choose two.)

• Segment routing must be configured on all PE routers.
• VXLAN must be configured on all PE routers.
• EVPN uses Type 2 routes to advertise MAC address and IP address pairs learned using ARP snooping
• EVPN uses Type 3 routes to join a multicast tree to flood traffic.

When building an interprovider VPN, you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unica3t configured.Which parameter must you configure to solve this problem?

• Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
• Under the protocols ospf hierarchy, add the traffic-engineering parameter.
• Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
• Under the protocols mpls hierarchy, add the traffic-engineering parameter

You want to ensure that L1 IS-IS routers have only the most specific routes available from L2 IS-IS routers. Which action accomplishes this task?

• Configure the ignore-attached-bit parameter on all L2 routers.
• Configure all routers to allow wide metrics.
• Configure all routers to be L1.
• Configure the ignore-attached-bit parameter on all L1 routers
