• Question 91:

  

  CE-1, CE-2, and CE-3 are part of a single VPLS VPN. An Ethernet frame has just arrived at PE-3 from CE-3. It has a source MAC address of CE-3 and a destination MAC address of CE-1. You want to know what PE-3 does with the Ethernet frame.

  Referring to the exhibit, which statement is correct?

  A. It drops the packet because the destination MAC address is not in PE-3's MAC table.
  B. It forwards the packet to PE-1 and PE-2.
  C. It forwards the packet to PE-1 only.
  D. It drops the packet because the destination MAC address is not for PE-3.
  B. It forwards the packet to PE-1 and PE-2.

• Question 92:

  

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

  A. Configure the join-load-balance parameter under PIM on R4.
  B. Configure the default route in inet.2 on R4 from R3 as the next hop to both R3 and R2.
  C. Configure the group-range parameter to be the same on R2 and R3.
  D. Configure the bootstrap priority on R2 to be the same as R3.
  A. Configure the join-load-balance parameter under PIM on R4.

• Question 93:

  Which two statements are true about what a route reflector does by default when distributing routes it has received from reflector clients? (Choose two.)

  A. It does not change any received BGP attributes.
  B. It changes the default BGP attributes to inform peers that it is a route reflector.
  C. It sets the next hop of all routes to "self" to prevent routing loops.
  D. It adds its cluster ID to the client-received routes.
  A. It does not change any received BGP attributes.
  D. It adds its cluster ID to the client-received routes.

• Question 94:

  You have a mixed vendor EVPN environment and you need to ensure VXLAN interoperability between all devices. In tins scenario, winch statement is correct?

  A. You should only use pure Type 2 routes.
  B. You should only use pure Type 5 routes.
  C. You should only use Type 2 and Type 5 routes.
  D. You should only use Type 6 and Type 2 routes.
  C. You should only use Type 2 and Type 5 routes.

• Question 95:

  

  You have the LDP signaled VPLS topology as shown in the exhibit. CE-B at Site-2 is multihomed to both PE-2 and PE-3. In this scenario, where would you configure loop prevention?

  A. PE-1
  B. CE-B
  C. PE-3
  D. PE-2
  A. PE-1

• Question 96:

  You are creating a new LDP signaled Layer 2 circuit between three customer sites. In this scenario, which two statements are correct? (Choose two.)

  A. BGP is used to exchange the virtual circuit labels with other PEs.
  B. You are allowed to tunnel your LDP sessions through RSVP LSPs.
  C. You are not allowed to use any RSVP-signaled LSPs in your core network.
  D. LDP is used to exchange the virtual circuit labels with other PEs.
  B. You are allowed to tunnel your LDP sessions through RSVP LSPs.
  D. LDP is used to exchange the virtual circuit labels with other PEs.
