CCNA2 Chapter 8 Exam  Answer v5.03 2016

  1. A router is participating in an OSPFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OSPF router?

    • OSPF will run a new DR/BDR election.
    • SPF will run and determine which neighbor router is “down”.
    • A new dead interval timer of 4 times the hello interval will start.
    • OSPF will remove that neighbor from the router link-state database.
  2. Which three statements describe the similarities between OSPFv2 and OSPFv3? (Choose three.)

    • They both are link-state protocols.
    • They both use the global address as the source address when sending OSPF messages.
    • They both share the concept of multiple areas.
    • They both support IPsec for authentication.
    • They both use the same DR/BDR election process.
    • They both have unicast routing enabled by default.
  3. Which OSPF component is identical in all routers in an OSPF area after convergence?

    • adjacency database
    • link-state database
    • routing table
    • SPF tree
  4. Which three statements describe features of the OSPF topology table? (Choose three.)

    • It is a link-state database that represents the network topology.
    • Its contents are the result of running the SPF algorithm.
    • When converged, all routers in an area have identical topology tables.
    • The topology table contains feasible successor routes.
    • The table can be viewed via the show ip ospf database command.
    • After convergence, the table only contains the lowest cost route entries for all known networks.

    • adjacency database
    • link-state database
    • forwarding database

  6. What is a function of OSPF hello packets?

    • to send specifically requested link-state records

    • hello
    • DBD
    • LSR
    • LSU
    • LSAck
  8. What are the two purposes of an OSPF router ID? (Choose two.)

    • to facilitate the establishment of network convergence
    • to uniquely identify the router within the OSPF domain
    • to facilitate the transition of the OSPF neighbor state to Full
    • to facilitate router participation in the election of the designated router
    • to enable the SPF algorithm to determine the lowest cost path to remote networks
  9. What is the first criterion used by OPSF routers to elect a DR?

    • highest priority
    • highest IP address
    • highest router ID
    • highest MAC address
  10. Which wildcard mask would be used to advertise the 192.168.5.96/27 network as part of an OSPF configuration?

    • 0.0.0.32
    • 0.0.0.31
    • 255.255.255.224
    • 255.255.255.223
  11. What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? (Choose two.)

    • a mismatched Cisco IOS version that is used
    • mismatched OSPF Hello or Dead timers
    • mismatched subnet masks on the link interfaces
    • use of private IP addresses on the link interfaces
    • one router connecting to a FastEthernet port on the switch and the other connecting to a GigabitEthernet port
  12. Refer to the exhibit. A network administrator issued the command show ip ospf interface on the router R2. What conclusion can be drawn?

    • R2 has not formed an adjacency with any other router.
    • R2 is configured with the OSPF router-id command.
    • R2 is not configured with default Hello and Dead timer values.
  13. What command would be used to determine if a routing protocol-initiated relationship had been made with an adjacent router?

    • ping
    • show ip protocols
    • show ip ospf neighbor
    • show ip interface brief
  14. Which OSPFv3 function works differently from OSPFv2?

    • metric calculation
    • hello mechanism
    • OSPF packet types
    • authentication
    • election process
  15. Which three addresses could be used as the destination address for OSPFv3 messages? (Choose three.)

    • FE80::1
    • FF02::5
    • FF02::6
    • FF02::A
    • FF02::1:2
    • 2001:db8:cafe::1
  16. What does a Cisco router use automatically to create link-local addresses on serial interfaces when OSPFv3 is implemented?

    • the highest MAC address available on the router, the FE80::/10 prefix, and the EUI-48 process
    • the FE80::/10 prefix and the EUI-48 process
    • the MAC address of the serial interface, the FE80::/10 prefix, and the EUI-64 process
    • an Ethernet interface MAC address available on the router, the FE80::/10 prefix, and the EUI-64 process
  17. A network administrator enters the command ipv6 router ospf 64in global configuration mode. What is the result of this command?

    • The router will be assigned an autonomous system number of 64.
    • The router will be assigned a router ID of 64.
    • The reference bandwidth will be set to 64 Mb/s.
    • The OSPFv3 process will be assigned an ID of 64.
