• Question 257:

  Which two statements are correct about a generated route? (Choose two.)

  A. A generated route requires at least two contributing active routes to be active.

  B. A generated route has a route preference of 150.

  C. The primary contributing route is the route with the lowest preference that falls within the aggregate range of prefixes.

• Question 258:

  Which three statements are correct about VRRP? (Choose three.)

  A. It requires speakers to be configured with BFD.

  B. It uses a virtual router MAC address for LAN communications.

  C. It uses multicast address 224.0.0.18.

  D. It is confined to the local network with a TTL of 255.

  Correct Answer: BCD

• Question 259:

  Click the Exhibit button.

  [edit]

  user@host# show protocols ospf3

  area 28.32.69.49 {

  interface all;

  }

  Click the Exhibit button.

  Which statement is true regarding the output shown in the exhibit?

  A. The configuration supports IPv4 multicast routes.

  B. The configuration supports IPv4 unicast routes.

  C. The configuration supports IPv6 unicast routes.

  D. The configuration supports IPv6 multicast routes.

  Correct Answer: C

  By default, OSPFv3 supports unicast IPv6 routes, but you can configure OSPFv3 to support multiple

  address families. To support an address family other than unicast IPv6, you configure a realm that allows

  OSPFv3 to advertise IPv4 unicast, IPv4 multicast, or IPv6 multicast routes.

  Example of a configuration which support both Ipv4 and Ipv6 prefixes:

  user@host# show protocols ospf3

  realm ipv4-unicast {

  area 0.0.0.0 {

  interface fe-0/1/0.0;

  }

  }

  area 0.0.0.0 {

  interface fe-0/1/0.0;

  }

• Question 260:

  Which three statements are true about GRE and IP-IP tunnels? (Choose three.)

  A. All intermediary devices must have reachability to the tunnel endpoints.

  B. Tunnel endpoints must use the loopback interface for reachability.

  C. Tunnel endpoints must have a route that directs traffic into the tunnel.

  D. Tunnel endpoints must have a route to the remote endpoint learned by a dynamic routing protocol.

  E. Tunnel endpoints require a tunnel interface.
