2. Which OSPF component is similar in all routers in an OSPF location after convergence?

adjacency database

link-state database*

routing table

SPF tree

3. Which OPSF packet includes the different types of link-state advertisements?






4. What happens immediately after 2 OSPF routers have exchanged hello packets and also have formed a neighbor adjacency?

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

You are watching: Match each ospf packet type to how it is used by a router. (not all options are used.)

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

They research even more information about their databases.

They exadjust abbreviated lists of their LSDBs.*

5. What will certainly an OSPF router favor to use first as a router ID?

any type of IP attend to that is configured making use of the router-id command*

a loopearlier interchallenge that is configured through the highest IP attend to on the router

the highest possible energetic interconfront IP that is configured on the router

the greatest active interface that participates in the routing procedure bereason of a specifically configured network-related statement

6. What are the 2 objectives of an OSPF rexternal ID? (Choose 2.)

to facilitate the facility of network convergence

to uniquely recognize the router within the OSPF domain*

to facilitate the shift of the OSPF neighbor state to Full

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

to allow the SPF algorithm to recognize the lowest price course to remote networks

7. By default, what is the OSPF price for any type of connect through a bandwidth of 100 Mb/s or greater?





8. Which command also need to be offered to inspect the OSPF procedure ID, the rexternal ID, netfunctions the rexternal is advertising, the neighbors the rexternal is receiving updates from, and also the default governmental distance?

display ip protocols*

present ip ospf neighbor

display ip ospf

present ip ospf interface

9. What are 2 factors that will prevent two routers from creating an OSPFv2 adjacency? (Choose two.)

a mismatched Cisco IOS variation that is used

mismatched OSPF Hello or Dead timers*

mismatched subnet masks on the attach interfaces*

use of exclusive IP addresses on the connect interfaces

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

10. Which 3 addresses could be used as the location address for OSPFv3 messages? (Choose 3.)







11. A network administrator enters the command also ipv6 router ospf 64 in international configuration mode. What is the result of this command?

The router will be assigned an autonomous system variety of 64.

The rexternal will certainly be assigned a router ID of 64.

The recommendation bandwidth will certainly be set to 64 Mb/s.

The OSPFv3 procedure will be assigned an ID of 64.*

12. When a netoccupational engineer is configuring OSPFv3 on a rexternal, which command would certainly the engineer worry immediately before configuring the rexternal ID?

ipv6 ospf 10 location 0

ipv6 rexternal ospf 10*

interchallenge serial 0/0/1

clear ipv6 ospf process

13. Single location OSPFv3 has actually been allowed on a rexternal using the ipv6 router ospf 20 command. Which command will certainly permit this OSPFv3 procedure on an interchallenge of that router?

ipv6 ospf 0 location 0

ipv6 ospf 20 location 20

ipv6 ospf 0 area 20

ipv6 ospf 20 area 0*

14. What does a Cisco router use automatically to develop link-regional addresses on serial interencounters as soon as OSPFv3 is implemented?

the greatest MAC address obtainable on the rexternal, the FE80::/10 predeal with, and also the EUI-48 process

the FE80::/10 presolve and also the EUI-48 process

the MAC resolve of the serial interconfront, the FE80::/10 presolve, and the EUI-64 process

an Ethernet interchallenge MAC deal with obtainable on the router, the FE80::/10 predeal with, and also the EUI-64 process*

15. Which command also will verify that a router that is running OSPFv3 has created an adjacency through various other routers in its OSPF area?

show running-configuration

present ipv6 ospf neighbor*

present ipv6 path ospf

display ipv6 interface brief

16. Which command will carry out information particular to OSPFv3 routes in the routing table?

display ip route ospf

present ip route

show ipv6 route

present ipv6 course ospf*

17. Match the OSPF state via the order in which it occurs. (Not all choices are provided.)


Place the options in the complying with order:second state -> Init state– not scored –seventh state -> Full statefifth state -> Exadjust statefirst state -> Dvery own statefourth state -> Exstart state– not scored –3rd state -> Two-means statesixth state -> Loading state

18. Match each OSPF packet kind to just how it is offered by a rexternal. (Not all choices are used.)


establish and also keep adjacencies = hello packet

advertise brand-new indevelopment = link-state update packet

compare local topology to that sent by one more rexternal = database summary packet

query one more router for additional indevelopment = link-state request packet

19. By order of precedence, enhance the selection of router ID for an OSPF-allow rexternal to the possible router ID alternatives. (Not all alternative are supplied.)


loopago interconfront resolve = Third precedence

Serial interconfront IP deal with = Fourth precedence

Configured rexternal ID = First precedence

Loopback interconfront IP address = 2nd precedence

20. Match the information to the command also that is used to obtain the information. (Not all choices are supplied.)


present ip ospf neighbor = Neighbor ID of

show ip ospf = Routing Process “ospf 10” through ID

show ip protocols = Routing Protocol is “ospf 10”

present interchallenge serial 0/0/0 = BW 1544 Kbit/sec

21. Fill in the empty.

OSPF provides “cost” as a metric.

22. Fill in the blank.

The election of a DR and a BDR takes area on “multiaccess” networks, such as Ethernet networks.
