    FF02::A

    FF02::1:2

    2001:db8:cafe::1

    FE80::1*

    FF02::6*

    FF02::5*

  2. Fill in the blank.

    OSPF uses _______ as a metric.
    Correct Answer: cost*

  3. What are the two purposes of an OSPF router ID? (Choose two.)

    to enable the SPF algorithm to determine the lowest cost path to remote networks

    to facilitate the establishment of network convergence

    to uniquely identify the router within the OSPF domain*

    to facilitate router participation in the election of the designated router*

    to facilitate the transition of the OSPF neighbor state to Full

  4. By default, what is the OSPF cost for any link with a bandwidth of 100 Mb/s or greater?

    100

    100000000

    1*

    10000

  5. What happens immediately after two OSPF routers have exchanged hello packets and have formed a neighbor adjacency?

    They exchange DBD packets in order to advertise parameters such as hello and dead intervals.

    They request more information about their databases.

    They exchange abbreviated lists of their LSDBs.*

    They negotiate the election process if they are on a multiaccess network.

  6. Open the PT Activity. Perform the tasks in the activity instructions and then complete the task. What message is displayed on www.ciscoville.com?

    Completion!*

    Success!

    Converged!

    Finished!

  7. What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? (Choose two.)

    a mismatched Cisco IOS version that is used

    one router connecting to a FastEthernet port on the switch and the other connecting to a GigabitEthernet port

    use of private IP addresses on the link interfaces

    mismatched OSPF Hello or Dead timers*

    mismatched subnet masks on the link interfaces*

  8. Which command will verify that a router that is running OSPFv3 has formed an adjacency with other routers in its OSPF area?

    show ipv6 interface brief

    show ipv6 ospf neighbor*

    show ipv6 route ospf

    show running-configuration

  9. Which OSPF component is identical in all routers in an OSPF area after convergence?

    adjacency database

    link-state database*

    SPF tree

    routing table

  10. Which OPSF packet contains the different types of link-state advertisements?

    DBD
    LSR
    hello
    LSAck
    LSU*

  11. A network administrator enters the command ipv6 router ospf 64 in 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.*

  12. What does a Cisco router use automatically to create link-local addresses on serial interfaces when OSPFv3 is implemented?

    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*

    the FE80::/10 prefix and the EUI-48 process

    the highest MAC address available on the router, the FE80::/10 prefix, and the EUI-48 process

  13. Single area OSPFv3 has been enabled on a router via the ipv6 router ospf 20 command. Which command will enable this OSPFv3 process on an interface of that router?

    ipv6 ospf 20 area 20

    ipv6 ospf 0 area 0

    ipv6 ospf 0 area 20

    ipv6 ospf 20 area 0*

  14. Fill in the blank.

    The election of a DR and a BDR takes place on _________ networks, such as Ethernet networks.
    Correct Answer: multiaccess*

  15. Which command will provide information specific to OSPFv3 routes in the routing table?

    show ip route ospf

    show ipv6 route

    show ipv6 route ospf*

    show ip route

  16. Which command should be used to check the OSPF process ID, the router ID, networks the router is advertising, the neighbors the router is receiving updates from, and the default administrative distance?

    show ip ospf neighbor

    show ip ospf

    show ip protocols*

    show ip ospf interface

  17. What is used to create the OSPF neighbor table?

    adjacency database*

    link-state database

    forwarding database

    routing table

  18. When a network engineer is configuring OSPFv3 on a router, which command would the engineer issue immediately before configuring the router ID?

    clear ipv6 ospf process

    interface serial 0/0/1

    ipv6 router ospf 10*

    ipv6 ospf 10 area 0

  19. What will an OSPF router prefer to use first as a router ID?

    the highest active interface that participates in the routing process because of a specifically configured network statement

    the highest active interface IP that is configured on the router

    any IP address that is configured using the router-id command*

    a loopback interface that is configured with the highest IP address on the router
