Modules 1 - 2: OSPF Concepts and
Configuration Exam Questions With Correct
Answers
What is a function of OSPF hello packets?
to send specifically requested link-state records
to discover neighbors and build adjacencies between them
to ensure database synchronization between routers
to request specific link-state records from neighbor routers - answer✔✔to discover neighbors
and build adjacencies between them
Which OPSF packet contains the different types of link-state advertisements?
hello
DBD
LSR
LSU
LSAck - answer✔✔LSU
Which three statements describe features of the OSPF topology table? (Choose three.)
It is a link-state database that represents the network topology.
Its contents are the result of running the SPF algorithm.
When converged, all routers in an area have identical topology tables.
The topology table contains feasible successor routes.
The table can be viewed via the show ip ospf database command.

, After convergence, the table only contains the lowest cost route entries for all known networks. -
answer✔✔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.
What does an OSPF area contain?
routers that share the same router ID
routers whose SPF trees are identical
routers that have the same link-state information in their LSDBs
routers that share the same process ID - answer✔✔routers that have the same link-state
information in their LSDBs
What is used to facilitate hierarchical routing in OSPF?
the use of multiple areas
frequent SPF calculations
autosummarization
the election of designated routers - answer✔✔the use of multiple areas
