CE1, CE2, and CE3 are part of a single VPLS VPN. R1, R2, and R3 are PEs in the provider network, and have just been powered on. The VPLS domain has converged, and frames have passed between all CEs in the last minute. An Ethernet frame has just arrived at R3 from CE3. It has a source MAC address of CE3 and a destination MAC address of CE1.What does R3 do with the Ethernet frame?

• A.Drops the packet as the destination MAC address is not for R3.
• B.Forwards the packet to R1 and R2.
• C.Forwards the packet to R1 only.
• D.Drops the packet as the destination MAC address is not in R3's MAC table.

In the exhibit, R1 and R2 have a static default route configured that points toward the provider. Both routers redistribute the default route into OSPF. R2 is the preferred gateway to reach the provider. R1 is the backup gateway. All link metrics are equal. Which two steps ensure that traffic to the provider flows through R2 while the network is working properly? (Choose two.)

• A.Modify the preference value of the default route on router R2 so that it is more preferred than OSPF external routes.
• B.Redistribute the default route as a Type 1 external route on router R1 and a Type 2 external route on router R2.
• C.Modify the preference value of the default route on router R1 so that it is less preferred than OSPF external routes.
• D.Redistribute the default route as a Type 2 external route on router R1 and a Type 1 external route on router R2.

You are asked to provide redundancy to avoid a single point of failure for your route reflector cluster groups.
Which action will accomplish this task?

• A.Configure unique cluster IDs for each client within a route reflector cluster group.
• B.Configure two route reflectors for each route reflector cluster group.
• C.Configure a full IBGP peer mesh between clients within the route reflector cluster group.
• D.Configure the no-client-reflect parameter on the route reflector.
