CCNA Advanced Routing Protocols Questions

  1. 1. Chapter 8True/FalseIndicate whether the statement is true or false.____ 1. Classful routing protocols can be used in networks with either discontiguous subnets or networks using variable length subnet masks (VLSM).____ 2. The message update format in RIPv1 does not have room for subnet mask information in the IP address field.____ 3. In general, due to the complexity of modern networks and the use of VLSMs, which require subnet mask information to be sent with update messages, most networks use classful routing protocols.____ 4. EIGRP uses nonperiodic, partial, and bounded routing table updates.____ 5. OSPF is ideally suited for large networks because it can use a concept known as areas to bound link-state advertisements.Multiple ChoiceIdentify the choice that best completes the statement or answers the question.____ 6. In general, ____ routing protocols send periodic updates of the entire routing table to their directly connected neighbors. a. link-state c. exterior gateway b. distance-vector d. interior gateway____ 7. In general, ____ routing protocols flood nonperiodic link-state advertisements of only changed routes throughout the entire internetwork. a. link-state c. exterior gateway b. distance-vector d. interior gateway____ 8. ____ routing protocols cannot adapt to work in an environment where discontiguous networks or VLSM exist. a. RIPv1 c. Classful b. Classless d. Class-oriented____ 9. The four bytes set aside for the ____ field allow RIPv2 to send the full 32-bit subnet mask for each network configured on the router’s interfaces. a. Next Hop c. Address Family Identifier b. IP Address d. Subnet Mask____ 10. The ____ command switches RIP to version 2. a. version 2 c. rip2 b. no auto-summary d. rip 2 on____ 11. The ____ command overrides RIPv2’s default behavior of summarizing to major network boundaries. a. no default c. auto-summary off b. no default summary d. no auto-summary____ 12. RIP authentication can occur either by passing the authentication keys in clear text or via ____ authentication. a. SSH c. MD5
  2. 2. b. RC4 d. SHA____ 13. Although it is often described as a hybrid protocol containing the features of both distance-vector and link-state protocols, EIGRP is still a ____ routing protocol at its core. a. link-state c. link-vector b. distance-vector d. distance-state____ 14. EIGRP uses the same metric as IGRP multiplied by ____. a. 32 c. 128 b. 64 d. 256____ 15. ____ allow EIGRP to support multiple Network layer routed protocols such as IP, IPX, and AppleTalk. a. Neighbor discovery and maintenance c. Reliable Transport Protocol b. Protocol Dependent Modules d. Diffusing Update Algorithm (DUAL)____ 16. ____ allow EIGRP to discover neighbors and keep track of their status. a. Reliable Transport Protocol c. Neighbor discovery and maintenance b. Protocol Dependent Modules d. Diffusing Update Algorithm (DUAL)____ 17. EIGRP uses multicast address ____ to multicast Hello packets every five seconds on most networks of T1 speed or greater. a. c. b. d. 18. Because EIGRP is protocol-independent, it cannot use existing Transport layer protocols to carry its various packet types. Instead, Cisco developed an entirely new layer 4 protocol, the ____, for use by EIGRP. a. Protocol Dependent Modules (PDM) c. Neighbor discovery and maintenance b. Reliable Transport Protocol (RTP) d. Diffusing Update Algorithm (DUAL)____ 19. DUAL uses the ____ topology table to track the status of all links in a network. a. EIGRP c. RIPv1 b. OSPF d. RIPv2____ 20. The ____ table contains information about all the networks a router can reach. a. RIP neighbors c. EIGRP topology b. OSPF status d. RIPv1 topology____ 21. In EIGRP, ____ is a good state, as it means all DUAL computations have been completed and the route is stable. a. active c. down b. fixed d. passive____ 22. ____ is an open standards, link-state routing protocol that supports classless routing, variable-length subnet masks, and authentication. a. OSPF c. RIPv1 b. EIGRP d. IGRP____ 23. In OSPF, a(n) ____ is the portion of a network within which LSAs are contained. a. domain c. container b. segment d. area____ 24. A(n) ____ in OSPF is a router’s interface. a. link-state c. link b. cost d. area
  3. 3. ____ 25. In OSPF, the ____ database contains information about all OSPF peers with which a router has successfully exchanged Hello packets. a. link-state c. cost b. adjacencies d. topological____ 26. OSPF uses a(n) ____ database, which holds the common view of the network formed from the link-state advertisements that are received. a. adjacencies c. link-state b. designated routers d. topologicalCompletionComplete each statement. 27. ____________________ routing protocols summarize networks to their major network boundaries (Class A, B, or C) and do not carry subnet mask information in their routing table updates. 28. ____________________ routing protocols offer the ability to carry subnet mask information in the routing table updates. 29. __________________________________________________ is a Cisco proprietary protocol designed to overcome the limitations found in IGRP. 30. ___________________________________ allow EIGRP to carry multiple routed protocols within their own native packet formats. 31. The ___________________________________ is the heart and soul of EIGRP, and is the reason that EIGRP can quickly recover from a link outage and route around network problems.Matching Match each item with a statement below: a.
