1. Which command will verify that a router that is running OSPFv3 has formed an adjacency with other routers in its OSPF area?
- show running-configuration
- show ipv6 ospf neighbor

2. Refer to the exhibit. Which would be chosen as the router ID of R2?
- 2001:DB8:CAFE:2::/64
- LLA: FE80::2
- 2001:DB8:CAFE:A001::/64
- The router ID has to be manually configured.
3. A network engineer is troubleshooting a single-area OSPFv3 implementation across routers R1, R2, and R3. During the verification of the implementation, it is noted that the routing tables on R1 and R2 do not include the entry for a remote LAN on R3. Examination of R3 shows the following:
- that all interfaces have correct addressing
- that the routing process has been globally configured
- that correct router adjacencies have formed
What additional action taken on R3 could solve the problem?
- Enable the OSPFv3 routing process on the interface connected to the remote LAN.
- Use the network command to configure the LAN network under the global routing process.
- Force DR/BDR elections to occur where required.
- Restart the OPSFv3 routing process.
4. An administrator is troubleshooting OSPFv3 adjacency issues. Which command would the administrator use to confirm that OSPFv3 hello and dead intervals are matching between routers?
- show ipv6 ospf interface
- show ipv6 ospf
- show ipv6 protocols
- show ipv6 ospf neighbor
5. An administrator is troubleshooting an OSPFv3 network and wants to view the PID, the RID, the reference bandwidth, and the area parameters for both IPv4 and IPv6 address families. Which single command can be used to display the information?
- show ip protocols
- show ospfv3
- show ipv6 ospf database
- show ipv6 ospf
6. Refer to the exhibit. What type of OSPF router is HQ-3?
- an ABR.
- an ASBR
- an OSPF internal router
- an OSPF edge router
7. Which command will verify that a router running OSPFv3 has received a redistributed default static route from another OSPFv3 router?
- default-information originate
- redistribute static
- show ipv6 route
- show ip route
8. A network administrator has enabled single-area OSPFv3 on a router via the ipv6 router ospf 100 command. Which command will enable this OSPFv3 process on an interface of that router?
- R1(config-router)# network 192.168.10.0 0.0.0.255 area 0
- R1(config-if)# ipv6 ospf 0 area 100
- R1(config-if)# ipv6 ospf 100 area 0
- R1(config-router)# network 192.168.10.0 0.0.0.255 area 100
9. After implementing an IPv6 network, the administrator notices that the OSPFv3 process is not starting on the routers. What could be the problem?
- The routers are configured with the default priority.
- Authentication was not implemented between the routers.
- No router IDs are configured on the routers.
- The routers were not configured with the network command.
10. Which command can be used by an administrator to display a list of interfaces that are enabled for OSPFv3?
- show ipv6 ospf
- show ipv6 neighbor
- show ipv6 route ospf
- show ipv6 protocols
11. Which OSPF LSA type provides information about IPv6 address prefixes associated with a transit network by referencing a network LSA?
- 7
- 8
- 6
- 9
12. Refer to the exhibit. An administrator applies the configurations to routers R1 and R2 respectively. Both routers use the FastEthernet0/0 interface to connect to the same Ethernet switch. However, a neighbor adjacency fails to form. What is a possible cause for the problem?
- The process IDs on R1 and R2 are identical.
- The router IDs on R1 and R2 are mismatched.
- The area numbers on R1 and R2 are mismatched.
- The interval timers have not been set.
