Review Questions

Answer the following questions, and then refer to Appendix A, "Answers to Review Questions," for the answers.

  1. Which three address blocks are summarizable?

    1. to
    2. to
    3. to
    4. to
    5. 2001:0DB8:C3B7:10A0::/64 to 2001:0DB8:C3B7:10DF::/64
    6. 2001:0DB8:1234:FB40::/64 to 2001:0DB8:1234:FB5F::/64
    7. to
  2. Which two can bit-splitting techniques be used for? (Choose two.)

    1. OSPF area design
    2. Summarizable address blocks with convenient role-based subnets
    3. Access list convergence
    4. Detecting summarizable address blocks
    5. Manual route summarization
  3. Which is the recommended design approach for OSPF?

    1. Configure a static default route everywhere for predictability.
    2. Configure static default routes using recursive routing for consistency.
    3. Originate the default at the edge and redistribute it into dynamic routing.
    4. Make the OSPF backbone area 0 stubby.
    5. Do not use additional parameters with the originate default command.
  4. Which two statements best describe redistribution?

    1. Redistribution works poorly with an arbitrary mix of routing protocols anywhere.
    2. Redistribution seldom requires route filters.
    3. Redistribution is not useful after a merger.
    4. Redistribution works well with a limited number of redistribution points.
    5. Redistribution prevents summarization.
  5. Select the best statement concerning EIGRP and OSPF routing design.

    1. Routing design needs to be done most carefully for small networks.
    2. OSPF should not be used for small networks.
    3. Routing design needs to be done most carefully for large networks.
    4. Route summarization must be used in all network designs.
    5. OSPF works best with a full mesh.
  6. Which three factors are the biggest influences on OSPF scalability?

    1. Flooding paths and redundancy
    2. Amount of routing information in the OSPF area or routing domain
    3. Number of routers capable of Cisco Express Forwarding
    4. Number of adjacent neighbors
    5. Other routing protocols in use
  7. Which statement best describes basic IBGP?

    1. IBGP is a link-state protocol.
    2. IBGP requires a full mesh of peers because it has no other way to prevent looping of routing information.
    3. IBGP inherently handles all full-mesh scalability issues.
    4. IBGP uses split horizoning to prevent looping of routing information.
    5. IBGP uses the autonomous system path to prevent looping of routing information.
  8. A route reflector reflects routes from a route reflector client to which three types of IBGP routers?

    1. Nonclient routers
    2. Sub-autonomous system members
    3. Other route reflector client routers
    4. EBGP peers
    5. IBGP peers configured for EIGRP or OSPF routing
