Question No: 236 – (Topic 3)

You want to ensure that all traffic arriving on interface fe-0/0/0.0 will be routed to next-hop 10.1.1.1, regardless of the more specific routes that might appear in the routing table. How can you accomplish this configuration?

  1. Configure a default route with a next hop of 10.1.1.1 and configure the always-use flag for the route.

  2. Configure and apply a firewall filter that sends all traffic to a routing instance, configure a default route in that routing instance, and configure the router to install interface routes in that routing instance.

  3. Configure a routing policy that matches all traffic and sets the next hop to 10.1.1.1, and configure a RIB group to ensure that the routing policy can resolve the next hop to 10.1.1.1.

  4. Configure a firewall filter that matches all traffic and sets the next hop to 10.1.1.1, apply the firewall filter to a RIB group, and assign the fe-0/0/0.0 interface to that RIB group.

Answer: B

Question No: 237 – (Topic 3)

What describes the action of the qualified-next-hop parameter in a configuration?

  1. It performs a recursive lookup on the destination network to confirm that the route is reachable.

  2. It allows for the configuration of independent preferences for static routes to the same destination.

  3. It periodically pings the next hop to validate its existence thereby assigning the static route to the forwarding table.

  4. It verifies the maximum hop count limit before validating the static route.

Answer: B

Ensurepass 2018 PDF and VCE

Router 2 is receiving two announcements of a route to 10.0.0.0/8. Router 2 learned one version of the route from ISP-2; this announcement of the route was received first. The second announcement of the route was received from Router 1 using IBGP. What will Router 2 do with the routes shown in the exhibit?

  1. Router 2 will choose to forward traffic toward ISP 2 because this route was learned first.

  2. Router 2 will choose to forward traffic toward Router 1 because newer routes are preferable.

  3. Router 2 will choose to forward traffic toward ISP 2 because EBGP-learned routes are preferred over IBGP-learned routes.

  4. Router 2 will choose to forward traffic toward Router 1 because IBGP-learned routes are preferred over EBGP-learned routes.
