• Question 122:

  Which three statements are true about tunneling IPv6 traffic over IPv4 networks? (Choose three.)

  A. The source tunnel endpoint encapsulates the native IPv6 packet inside IPv4
  B. The source tunnel endpoint disassembles the IPv6 packet and reassembles it as IPv4
  C. The intermediary hops are responsible for de-encapsulating and re-encapsulating the IPv4 packet to process the IPv6 payload
  D. The source tunnel endpoint forwards the IPv4 network with the encapsulated IPv6 payload through the IPv4 network
  E. The destination tunnel endpoint de-encapsulates the IPv6 packet and forwards/processes the packet natively
  A. The source tunnel endpoint encapsulates the native IPv6 packet inside IPv4
  D. The source tunnel endpoint forwards the IPv4 network with the encapsulated IPv6 payload through the IPv4 network
  E. The destination tunnel endpoint de-encapsulates the IPv6 packet and forwards/processes the packet natively

  Referring to the exhibit, the GRE tunnel between R-1 and R2 allows connectivity between User-1 and Server-1. User-1 can communicate with Server-1 with packets that are up to 1448 bytes in size. However, if the packet size is larger than 1448, User-1 cannot communicate with Server-1. In this scenario, how do you solve the communication problem?

  A. Change the physical MTU on the ge-0/0/3 interfaces on R-1 and R-2 to 1448 bytes.
  B. Change the physical MTU on the gr-0/0/0 interfaces on R-1 and R-2 to 1448 bytes.
  C. Apply the allow-fragmentation statement to the GRE tunnel configuration.
  D. Apply the path-mtu-discovery statement to the GRE tunnel configuration.
  C. Apply the allow-fragmentation statement to the GRE tunnel configuration.

• Question 124:

  What is the role of the route distinguisher (RD) in a Layer 3 VPN?

  A. The RD controls the allocation of MPLS labels within a VRF.
  B. The RD allows different VRFs to contain the same IP prefixes.
  C. The RD is used to create unique routing processes within the global routing instance.
  D. The RD is used to control the import and export of routes within a VRF.
  B. The RD allows different VRFs to contain the same IP prefixes.

• Question 125:

  Click the Exhibit.

  

  You have just configured a GRE tunnel, but you notice that the GRE tunnel is flapping. Referring to the exhibit, which two would you take to solve this problem? (Choose two.)

  A. Add a specific static route to the local peer's network with the remote devices'loopback address as the next-hop gateway.
  B. Add a specific route to the remote device's loopback address with the next-hop device defined as the next-hop gateway.
  C. Set the GRE interface with a larger TTL value.
  D. Remove the existing 192.168.2.0/30 static route.
  B. Add a specific route to the remote device's loopback address with the next-hop device defined as the next-hop gateway.
  D. Remove the existing 192.168.2.0/30 static route.

  Based on the illustration shown in the exhibit, what would PE-B do with a VPLS packet received from PE-A if the matching entry in its VPLS routing table showed the destination was connected to PE-D?

  A. PE-B would flood the packet to all attached PEs
  B. PE-B would forward the packet to the root PE device
  C. PE-B would forward the packet to all attached CE devices
  D. PE-B would discard the packet
  C. PE-B would forward the packet to all attached CE devices
