OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as intended. Which configuration change would ensure that R1 would receive a default route from R2?
A. Add the area 1 stub command on routers R1.
B. Add the always keyword to the default-information originate configuration command on router R2.
C. Remove the default information originate configuration command from router R2 and place it on router R1.
D. Add the ip route 184.108.40.206 255.255.255.0 0.0.0.0 command to router R2.
Refer to the exhibit.
OSPF has been configured on all routers in the network and Area 1 has been configured as a NSSA. Which statement is true about the NSSA Area 1?
A. Redistributed RIP and IGRP routes will appear in Area 1. They will be advertised via type 5 LSAs.
B. Only redistributed RIP routes will appear in Area 1. They will be advertised via type 7 LSAs.
C. Only redistributed IGRP routes will appear in Area 1. They will be advertised via type 7 LSAs.
D. No redistributed routes can appear in Area 1, only summary routes.
According to RFC 2328, what is the stateful order in which an OSPF router transitions to a full adjacency with a neighbor router?
A. Down, Init, 2-Way, Exstart, Exchange, Loading, and Full
B. Down, Init, 2-Way, Exchange, Exstart, Loading, and Full
C. Down, 2-Way, Init, Loading, Exstart, Exchange, and Full
D. Down, 2-Way, Init, Exchange, Exstart, Loading, and Full
E. Down, Init, 2-Way, Loading, Exstart, Exchange, and Full
F. Down, 2-Way, Init, Exstart, Exchange, Loading, and Full
You have been tasked with setting up OSPF on an existing company router usingIPv6. Which command enables OSPF for IPv6 on a router?
A. ipv6 router ospf process-id
B. router ospf process-id
C. router ospf ipv6 process-id
D. ipv6 ospf process-id area-id
E. None of the above
One of the most important characteristics of OSPF is multiple areas. Which statement best describes why this feature is such an important enhancement to earlier routing protocols?
A. The network domain, when divided into areas, allows for the use of both IANA classful addressing and private addressing.
B. The use of multiple areas allows for the use of prioritization.
C. All computation is kept within the area, with minimum communication between the areas, allowing the network to scale to larger sizes.
D. It is easier to implement security.
When learning a new route, if a LSA received is not found in the topological database, what will an internal OSPF router do?
A. The sequence numbers are checked, and if the LSA is valid it is entered into the topology database.
B. The LSA is placed in the topological database and an acknowledgement is sent to the transmitting router.
C. The LSA is dropped and a message is sent to the transmitting router.
D. The LSA is flooded immediately out of all the OSPF interfaces, except the interface from which the LSA was received.
Which statement is correct based upon the following output from the show command on RT1?
A. OSPFv3 establishes neighbor adjacencies by using Link-local addresses.
B. OSPFv3 establishes neighbor adjacencies by using IPv4 addresses.
C. OSPFv3 establishes neighbor adjacencies by using global IPv6 addresses.
D. RT1 owns a subnet mask of 64 bits.
Refer to the exhibit.
OSPF is configured on all routers in the network. Area 5 is configured as an NSSA area. The RIPv2 routes are redistributed into the OSPF domain on router R5. What two types of LSAs will be originated by router R5? (Choose two.)
A. type 1 Router LSA
B. type 2 Network LSA
C. type 3 Network Summary LSA
D. type 4 ASBR Summary LSA
E. type 5 AS External LSA
F. type 7 NSSA External LSA
A network administrator has enabled OSPF across an NBMA network and has issued the command ip ospf network nonbroadcast. Given those facts, which two statements are true? (Choose two.)
A. DR and BDR elections will occur.
B. DR and BDR elections will not occur.
C. All routers must be configured in a fully meshed topology with all other routers.
D. The neighbor command is required to build adjacencies.
E. Interfaces will automatically detect and build adjacencies with neighbor routers.
Refer to the topology diagram.
