Refer to the exhibit. What three conclusions can be drawn from the displayed output? (Choose three.)

Refer to the exhibit. Which conclusion can be drawn from this OSPF multiaccess network?​

When checking a routing table, a network technician notices the following entry: O*E2 0.0.0.0/0 [110/1] via 192.168.16.3, 00:20:22, Serial0/0/0 What information can be gathered from this output?

Which command will a network engineer issue to verify the configured hello and dead timer intervals on a point-to-point WAN link between two routers that are running OSPFv2?

A network engineer suspects that OSPFv3 routers are not forming neighbor adjacencies because there are interface timer mismatches. Which two commands can be issued on the interface of each OSFPv3 router to resolve all timer mismatches? (Choose two.)

Refer to the exhibit. What kind of OSPF authentication has been configured on this interface?

Which two pieces of information are used by the OSPF MD5 algorithm to generate a signature? (Choose two.)

What is a recommended method of authentication for OSPFv3?

A network engineer is troubleshooting convergence and adjacency issues in an OSPFv2 network and has noted that some expected network route entries are not displayed in the routing table. Which two commands will provide additional information about the state of router adjacencies, timer intervals, and the area ID? (Choose two.)

When OSPFv2 neighbors are establishing adjacencies, in which state do they elect a DR and BDR router?

A network engineer is troubleshooting an OSPFv2 network and discovers that two routers connected by a point-to-point WAN serial link are not establishing an adjacency. The OSPF routing process, network commands and area ID are all confirmed as correct, and the interfaces are not passive. Testing shows that the cabling is correct, that the link is up, and pings between the interfaces are successful. What is most likely the problem?

A network engineer is troubleshooting OSPFv2 routing issues on two connected routers. Which two requirements to form an adjacency need to be verified? (Choose two.)

Which command is used to verify that OSPF is enabled and also provides a list of the networks that are being advertised by the network?​

A fully converged five router OSPF network has been running successfully for several weeks. All configurations have been saved and no static routes are used. If one router loses power and reboots, what information will be in its routing table after the configuration file is loaded but before OSPF has converged?

Refer to the exhibit. R1 and R2 are connected to the same LAN segment and are configured to run OSPFv3. They are not forming a neighbor adjacency. What is the cause of the problem?

Refer to the exhibit. Four routers are connected to an Ethernet LAN segment and are configured to run OSPFv3. However, none of the routers are receiving routing updates. What is the cause of the problem?

Refer to the exhibit. These two routers are configured to run OSPFv3 but they are not forming a neighbor adjacency. What is the cause of the problem?

During verification or troubleshooting of the OPSFv3 configuration on a router, which three parameters are displayed by the show ipv6 ospf interface command? (Choose three.)

Refer to the exhibit. Fill in the blank. Do not use abbreviations. The command [blank_start]show ipv6 route[blank_end] can be issued on router R2 to verify the propagation of a static default route from R1 to R2.

Fill in the blank. Do not use abbreviations. When IPv4 and OSPFv2 are being used, the command [blank_start]show ip ospf neighbor[blank_end] is used to verify that a router has formed an adjacency with its neighboring routers.

Match each OSPF state to its function. (Not all options are used.)

Match each OSPF election criterion to its sequential order for the OSPF DR and BDR election process. (Not all options are used.)

The PT initialization was skipped. You will not be able to view the PT activity. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Which task has to be performed on Router 1 for it to establish an OSPF adjacency with Router 2?
