RP1 and RP2 are acting as PIM-SM rendezvous points (RPs) in their autonomous system.
Referring to the diagram, which purpose does the MSDP session between RP1 and RP2 serve?

• A.MSDP allows RPs in different PIM domains to advertise any active multicast receivers to each other.
• B.MSDP routes are used by an RP for reverse path forwarding lookups when multicast sources exist in different autonomous systems.
• C.MSDP allows RPs in different PIM domains to advertise any active multicast sources to each other.
• D.MSDP allows RPs in different PIM domains to form PIM neighbor relationship with each other.

A PE provides VLAN VPLS service to a CE attached with two links. You want to prevent Layer 2 loops and provide link redundancy.
Which two actions will accomplish this task? (Choose two.)

• A.Place both interfaces in a link aggregation group.
• B.Configure Spanning Tree Protocol between the PE and the CE.
• C.Configure different VLANs on each interface.
• D.Configure all VLANs on both interfaces, on the PE, and on the CE.

You have a Layer 3 VPN established between Site 1 and Site 2. You are asked to limit the number of OSPF routes that the PE devices will accept from the CEs.
Which statement is correct?

• A.You should use the route-target filtering feature to limit the accepted routes.
• B.You should use the prefix-limit feature to limit the number of accepted routes.
• C.You should use the allow feature to limit the accepted routes.
• D.You should use the maximum-prefixes feature to limit the number of accepted routes.

The exhibit displays an IS-IS topology and an IS-IS configuration for R3 and R4. R4 cannot reach any external destinations or addresses located in Area 49.1111.
How would you ensure that R4 can reach external destinations and addresses located in area 49.1111?

• A.Remove the ignore-attached-bit statement on R4.
• B.Configure R3's authentication key to match R4's authentication key.
• C.Remove the overload statement on R4.
• D.Configure an export policy on R3 that leaks all IS-IS routes from Level 2 to Level 1.

You have configured PIM dense mode on your network. One of your PIM-enabled routers is not in the path of the source-based tree between the source and the receivers, and has no need for the multicast traffic. Which behavior would you expect from that router?

• A.The router will send graft messages to its upstream router.
• B.The router will send prune messages to its upstream router.
• C.The router will send assert messages to the RP.
• D.The router will send register stop messages to the RP.
