CNS CISCO 3 MODULE 1 AND 2

What is a function of OSPF five types of packets?

• to discover neighbors and build adjacencies between them

• 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.

Which three statements describe features of the OSPF topology table? (Choose three.)

• to discover neighbors and build adjacencies between them

• 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.

1.    Which OPSF packet contains the different types of link-state advertisements?

What does an OSPF area contain?

• routers that have the same link-state information in their LSDBs

• multiple areas

• link-state database

• exchanges link-state advertisements

What is used to facilitate hierarchical routing in OSPF?

• routers that have the same link-state information in their LSDBs

• the use of multiple areas

• link-state database

• exchanges link-state advertisements

Which OSPF data structure is identical on all OSPF routers that share the same area?

• routers that have the same link-state information in their LSDBs

• the use of multiple areas

• link-state database

• exchanges link-state advertisements

Which step does an OSPF-enabled router take immediately after establishing an adjacency with another router?

• routers that have the same link-state information in their LSDBs

• the use of multiple areas

• link-state database

• exchanges link-state advertisements

1.    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 now be 60 seconds.

• The R1 dead timer expires between hello packets from R2.

• dead interval

• hello interval

1.    Refer to the exhibit. A network administrator has configured the OSPF timers to the values that are shown in the graphic. What is the result of having those manually configured timers?

• The dead interval will now be 60 seconds.

• The R1 dead timer expires between hello packets from R2.

• dead interval

• hello interval

1.    To establish a neighbor adjacency two OSPF routers will exchange hello packets. Which two values in the hello packets must match on both routers? (Choose two.)

• The dead interval will now be 60 seconds.

• The R1 dead timer expires between hello packets from R2.

• dead interval

• hello interval
