The company and the company network have both been growing rapidly. Multiple adds, moves and changes have been applied to the network. Your boss has asked you to troubleshoot a recent OSPF synchronization problem that has arisen. There have been synchronization problems at separate locations in the OSPF area 0. There have been reported link failures during the rapid growth of the company network. You are required to resolve the OSPF problem. OSPF must be able to converge when the network changes.
Refer to the information above to answer the following question.
The R2 router has lost connectivity to R1. The following is R1s current route table:

Which expected route is missing from R1s route table based on the topology during the maintenance period?'

• A. o 172.16.0.0 [110/2] via 10.138.43.1, 00:00:09, FastEthernet0/0
• B. o 8.187.175.82 [110/3] via 10.138.43.1, 00:00:09, FastEthernet0/0
• C. o IA 10.138.0.0 [110/3] via 10.138.43.1, 00:00:09, FastEthernet0/0
• D. o IA 4.249.113.59 [110/2] via 10.138.43.1, 00:00:09, FastEthernet0/0
• E. o IA 10.249.0.0 [110/2] via 10.138.43.1, 00:00:09, FastEthernet0/0
• F. o IA 9.152.105.122 [110/3] via 10.138.43.1, 00:00:09, FastEthernet0/0

Refer to the exhibit. On the basis of the output from the show ipv6 interface command, what two statements must be true? (Choose two.)

• A. The IP address of the designated router (DR) is FE80::A8BB:CCFF:FE00:6E00.
• B. OSPF version 3 is enabled to support IPv6.
• C. Interface Ethernet 0/0 was configured with the ipv6 ospf 1 area 1 command.
• D. This is the designated router (DR) on the Ethernet 0/0 link.
• E. Interface Ethernet 0/0 has been configured with the ipv6 ospf authentication ipsec spi 500 md5 command.

A network administrator is troubleshooting a redistribution of OSPF routes into EIGRP.

Given the exhibited commands, which statement is true?

• A. Redistributed routes will have a default metric of 0 and will be treated as reachable and advertised.
• B. Redistributed routes will have an external type of 1 and a metric of 1.
• C. Redistributed routes will maintain their original OSPF routing metric.
• D. Redistributed routes will have an external type of 2 and a metric of 20.
• E. Redistributed routes will have a default metric of 0 but will be treated as unreachable and not advertised.

When an OSPF design is planned, which implementation can help a router not have memory resource issues?

• A. Have a backbone area (area 0) with 4 routers and 30,000 external routes injected into OSPF.
• B. Have less OSPF areas to reduce the need for interarea route summarizations.
• C. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinations.
• D. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2.

Router RTA is configured as follows:
RTA (config)#router rip
RTA(config-router)#network 10.0.0.0
RTA(config-router)#distribute-list 44 in interface BRIO
RTA(config-router)#exit
RTA(config)#access-list 44 deny 172.16.1.0 0.0.0.255
RTA(config)#access-list 44 permit any What are the effects of this RIP configuration on router RTA? (Choose two)

• A. the routing table on router RTA will be updated with the route to router RTW
• B. router RTA will not advertise the 10.0.0.0 network to router RTX
• C. the route to network 172.16.1.0 will not be entered into the routing table on router RTA
• D. user traffic from the 172.16.1.0 network is denied by access-list 44
• E. no routing updates will be sent from router RTA on interface BRIO to router RTX
