   R4 is directly connected to both RPs (R2 and R3). R4 is currently sending all joins upstream to R3 but you want all joins to go to R2 instead. Referring to the exhibit, which configuration change will solve this issue?

   • AChange the bootstrap priority on R2 to be higher than R3.
   • BChange the local address on R2 to be higher than R3.
   • CChange the default route in inet.2 on R4 from R3 as the next hop to R2.

   You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. Your PE-2 device connects to two sites within the same VPN. In this scenario, which statement is correct?

   • AYou must create a unique Layer 2 VPN routing instance for each site on the PE-2 device.
   • BBy default on PE-2, the site’s local ID is automatically assigned a value of 0 and must be configured to match the total number of attached sites.
   • CYou must use separate physical interfaces to connect PE-2 to each site.
   • DBy default on PE-2, the remote site IDs are automatically assigned based on the order that you add the interfaces to the site configuration.
