The dead interval will now be 60 seconds.

A network engineer has manually configured the hello interval to 15 seconds on an interface of a router that is running OSPFv2. By default, how will the dead interval on the interface be affected? The dead interval will not change from the default value. The dead interval will now be 30 seconds. The dead interval will now be 60 seconds. The dead interval will now be 15 seconds.

R5 was not elected DR or BDR.

Refer to the exhibit. Which of the following would explain the neighbor state between R5 and neighbor 4.4.4.4? The OSPF neighbor negotiation process needs more time to finish. R5 already has a FULL state with 2.2.2.2 and 1.1.1.1 and it does not support any more FULL neighbors R5 was not elected DR or BDR. On a shared network segment, FULL neighbor relations with other routers will only form between two DROTHER routers.

The OSPF Hello packets are sent to a BDR.

R1's OSPF hello-interval is 10 seconds.

Refer to the exhibit. A network administrator is troubleshooting a failed OSPF neighbor relationship between the routers R1 and R2. The administrator can ping R2 from R1 but still, the neighbor relationship between R1 and R2 is not formed. Based on the given output, what is causing the problem? 1 and R2 are not connected to the same area. R1's OSPF hello-interval is 10 seconds. R2 is an ABR. R1's interface FastEthernet 0/0 is configured in the wrong area. The OSPF process number is the same on both routers.

AREA 23 is not directly connected to the backbone AREA.

Refer to the exhibit. A network administrator noticed that routes from AREA 23 are showing in AREA 12 but not showing up in AREA 0. At the same time, routes from AREA 12 are showing up in AREA 0. Which of the following is most likely the cause? AREA 23 is not directly connected to the backbone AREA. A prefix-list on the ABR is filtering all the routes coming into AREA 0 from AREA 23. A prefix-list on the ABR is filtering all the routes coming into AREA 12 from AREA 23. R3 is not configured as an ABR and can't send type 3 LSA's

The route to 172.16.1.0/24 will not propagate to other routers in area 0.

Refer to the exhibit. A network administrator typed three "show..." commands into router R2. Based on the given output, what did the administrator accomplish? The route to 172.16.1.0/24 will not propagate to other routers in area 0. The route to 172.16.1.0/24 will not propagate to other routers in area 12. The route to 172.16.1.0/24 will propagate to other routers in area 0, other routes from area 12 will be filtered. The route to 172.16.1.0/24 will propagate to other routers in area 12, other routes from area 0 will be filtered.

192.168.1.1

Refer to the exhibit. An administrator enables OSPF on the router R2. Based on the output in the graphic, what will be R2's Router ID in the OSPF process? 192.168.1.1 2.0.0.2 212.222.234.233 10.12.0.2

R2 will drop the packet.

Refer to the exhibit. Router R2 receives an IP packet with a destination address of 172.16.0.241. Based on the given output, what action will R2 take regarding this packet? R2 will forward the packet out interface FastEthernet0/0. R2 will forward the packet out interface FastEthernet0/1. R2 will drop the packet. R2 will flood the packet out of all it's active interfaces.

LSA type 3

Refer to the exhibit. What LSA type did R1 receive to learn about the 172.30.23.0/24 network? LSA type 1 LSA type 2 LSA type 3 LSA type 4 LSA type 5 LSA type 7

R2 is a BDR. The OSPF network type between R2 and 3.3.3.3 is point-2-point

Refer to the exhibit. What can be assumed based on the given output? (Choose two.) R2 is a BDR. The OSPF network type between R2 and 3.3.3.3 is point-2-point. R2 is the DR. R2 is an ABR. The OSPF network type between R2 and 3.3.3.3 is BROADCAST. R2 is an ASBR.

The Administrator did not change the default hello and dead timers This router is the BDR.

Refer to the exhibit. Which of the following can be learned from the given output? (Choose two.) The command router ospf 11 was used on R4. The Administrator did not change the default hello and dead timers. This router is the DR. This router is the BDR. This router is an ABR. This router has only one neighbor.

dead interval hello interval Area ID

To establish a neighbor adjacency two OSPF routers will exchange hello packets. Which three values in the hello packets must match on both routers? (Choose three.) dead interval router priority list of neighbors router ID hello interval Area ID

routers that have the same information in their link-state data-base.

What does an OSPF area include? routers that share the same router ID routers whose SPF trees are identical routers that have the same information in their link-state data-base. routers that share the same process ID

bandwidth

What factors are used to calculate the OSPF cost? Bandwidth, delay Bandwidth Delay Bandwidth, MTU

to discover neighbors and build adjacencies between them

What is a function of OSPF hello packets? to send specifically requested link-state records to discover neighbors and build adjacencies between them to ensure database synchronization between routers to request specific link-state records from neighbor routers

Any 32-bit sequence in IP address format hat is configured using the router-id command.

Which of the following would an OSPF router prefer to use first as a router ID? a loopback interface that is configured with the highest IP address on the router Any 32-bit sequence in IP address format hat is configured using the router-id command. the highest active interface IP that is configured on the router. the highest active interface that participates in the routing process because of a specifically configured network statement.

It is a link-state database that represents the network topology. When converged, all routers in an area have identical topology tables. 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.

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.
