What is a function of OSPF hello to discover neighbors and build adjacencies
packets? between them
Which OPSF packet contains the LSU
different types of link-state

Which statements describe features 1.) The table can be viewed via the show ip ospf
of the OSPF topology table? database command.
(Choose three.) 2.) It is a link-state database that represents the
network topology.
3.) When converged, all routers in an area have
identical topology tables.
What does an OSPF area contain? routers that have the same link-state information in
their LSDBs
,A router is participating in an OSPFv2 OSPF will remove that neighbor from the router
domain. What will always happen if link-state database.
the dead interval expires before the
router receives a hello packet from
an adjacent DROTHER OSPF router?
What is the order of packet types Hello, DBD, LSR, LSU, LSAck
used by an OSPF router to establish
convergence?
What is a feature of the OSPF routing It scales well in both small and large networks.
protocol?
What is used to create the OSPF adjacency database
neighbor table?
What is identical on all OSPF routers link-state database
within a single area?
What function is performed by the dissemination of LSAs
OSPF designated router?
What are two reasons for creating an 1.) to reduce use of memory and processor
OSPF network with multiple areas? resources
(Choose two.) 2.) to reduce SPF calculations
At which OSPF state are neighbor Full
routers converged and able to
exchange routing updates?
, The OSPF hello timer has been set to 60 seconds
15 seconds on a router in a point-to-
point network. By default, what is the
dead interval on this router?
What happens immediately after two They exchange abbreviated lists of their LSDBs.
OSPF routers have exchanged hello
packets and have formed a neighbor
adjacency?
Which statement is correct about Arranging routers into areas partitions a large
multiarea OSPF? autonomous system in order to lighten the load on
routers.
Which OSPF data structure is Link-state database
identical in all routers in an OSPF
area after convergence?
What are the purposes of an OSPF 1.) To facilitate router participation in the election of
router ID? (Choose two.) the designated router
2.) To uniquely identify the router within the OSPF
domain
Which statement describes a It has a core backbone area with other areas
multiarea OSPF network? connected to the backbone area.
What are the advantages of using 1.) It improves routing efficiency by reducing the
multiarea OSPF? (Choose two.) routing table and linkstate update overhead.
2.) Topology changes in one area do not cause SPF
recalculations in other areas.
