Answer the following questions, and then refer to Appendix A, "Answers to Review Questions," for the answers.
Which three address blocks are summarizable?
- 172.16.20.0/24 to 172.16.27.0/24
- 172.16.20.0/24 to 172.16.23.0/24
- 10.16.0.0/16 to 10.31.0.0/16
- 10.16.0.0/16 to 10.47.0.0/16
- 2001:0DB8:C3B7:10A0::/64 to 2001:0DB8:C3B7:10DF::/64
- 2001:0DB8:1234:FB40::/64 to 2001:0DB8:1234:FB5F::/64
- 10.96.0.0/16 to 10.159.0.0/16
Which two can bit-splitting techniques be used for? (Choose two.)
- OSPF area design
- Summarizable address blocks with convenient role-based subnets
- Access list convergence
- Detecting summarizable address blocks
- Manual route summarization
Which is the recommended design approach for OSPF?
- Configure a static default route everywhere for predictability.
- Configure static default routes using recursive routing for consistency.
- Originate the default at the edge and redistribute it into dynamic routing.
- Make the OSPF backbone area 0 stubby.
- Do not use additional parameters with the originate default command.
Which two statements best describe redistribution?
- Redistribution works poorly with an arbitrary mix of routing protocols anywhere.
- Redistribution seldom requires route filters.
- Redistribution is not useful after a merger.
- Redistribution works well with a limited number of redistribution points.
- Redistribution prevents summarization.
Select the best statement concerning EIGRP and OSPF routing design.
- Routing design needs to be done most carefully for small networks.
- OSPF should not be used for small networks.
- Routing design needs to be done most carefully for large networks.
- Route summarization must be used in all network designs.
- OSPF works best with a full mesh.
Which three factors are the biggest influences on OSPF scalability?
- Flooding paths and redundancy
- Amount of routing information in the OSPF area or routing domain
- Number of routers capable of Cisco Express Forwarding
- Number of adjacent neighbors
- Other routing protocols in use
Which statement best describes basic IBGP?
- IBGP is a link-state protocol.
- IBGP requires a full mesh of peers because it has no other way to prevent looping of routing information.
- IBGP inherently handles all full-mesh scalability issues.
- IBGP uses split horizoning to prevent looping of routing information.
- IBGP uses the autonomous system path to prevent looping of routing information.
A route reflector reflects routes from a route reflector client to which three types of IBGP routers?
- Nonclient routers
- Sub-autonomous system members
- Other route reflector client routers
- EBGP peers
- IBGP peers configured for EIGRP or OSPF routing
