  1. List some considerations for redundant networks.

  2. How does address summarization help keep a network stable?

  3. List some path control tools.

  4. Indicate whether each statement is referring to OSPF or EIGRP.

    Statement

    Routing Protocol

    Metric can be changed only for external routes at redistribution points.

    Next hop can be set for all routes under various conditions.

    Can be configured only on ABRs and ASBRs.

  5. Select the true statements.

    2. Offset lists increase the incoming metric of routes.
    3. A distribute list allows an access list to be applied to routing updates.
    4. If a prefix is permitted, the route is used. If a prefix is denied, the route is not used.
    5. Offset lists decrease the incoming metric of routes.

    2. If the statement is marked as deny, a packet meeting the match criteria is dropped.
