A small branch has a simple, stable path to a central network. An administrator wants to specify the destination prefix and next-hop router manually. Which routing approach fits this requirement?

  1. A

    Configure a dynamic link-state protocol to learn the route automatically.

  2. B

    Enter a static route specifying the destination prefix and next hop.

  3. C

    Use a path-vector protocol to advertise the route between autonomous systems.

  4. D

    Rely on the router to infer the route from the destination address alone.

A router has an IPv4 default route and no more-specific route matches a packet's destination. What role does the default route serve?

  1. A

    It replaces every more-specific route in the table.

  2. B

    It is used only for destinations on the router's directly connected network.

  3. C

    It provides a next hop for destinations that have no matching more-specific route.

  4. D

    It prevents the router from forwarding packets to unknown destinations.

A router's manually configured static route uses a next-hop router that has failed. What should be expected if no tracking or failover mechanism is configured?

  1. A

    The router automatically learns a replacement route through the static route.

  2. B

    The route does not automatically adapt unless additional tracking or failover mechanisms are configured.

  3. C

    The route remains usable because a return path is no longer needed.

  4. D

    The router converts the route into a dynamic route when the next hop fails.

A network needs to exchange paths with other autonomous systems and make route choices influenced by policy and path attributes. Which routing protocol best fits this role?

  1. A

    RIP, because it shares hop-count distances with neighboring routers

  2. B

    OSPF, because it builds a topology database from link-state information

  3. C

    A static route, because it is entered manually by an administrator

  4. D

    BGP, because it advertises paths between autonomous systems and supports policy-based decisions
