OSPF Routing

Which OSPF component is identical in all routers in an OSPF area after convergence?

• routing table
• link-state database
• SPF tree
• adjacency database

A router is participating in an OPSFv2 domain. What will always happen if the dead interval expires before the router receives a hello packet from an adjacent DROTHER OPSF router?

• SPF will run and determine which neighbor router is “down”.
• OSPF will run a new DR/BDR election.
• OSPF will remove that neighbor from the router link-state database.
• A new dead interval timer of 4 times the hello interval will start.

Which command will provide information specific to OSPFv3 routes in the routing table?

• show ip route ospf
• show ip route
• show ipv6 route ospf
• show ipv6 route

Which wildcard mask would be used to advertise the 192.168.5.96/27 network as part of an OSPF configuration?

• 0.0.0.32
• 0.0.0.31
• 255.255.255.223
• 255.255.255.224

A network administrator enters the command ipv6 router ospf 64 in global configuration mode. What is the result of this command?

• The OSPFv3 process will be assigned an ID of 64.
• The router will be assigned a router ID of 64.
• The router will be assigned an autonomous system number of 64.
• The reference bandwidth will be set to 64 Mb/s.

Fill in the blank.
OSPF uses    ” _______ ”    as a metric.

Which command should be used to check the OSPF process ID, the router ID, networks the router is advertising, the neighbors the router is receiving updates from, and the default administrative distance?

• show ip protocols
• show ip ospf interface
• show ip ospf
• show ip ospf neighbor

Which OSPFv3 function works differently from OSPFv2?

• authentication
• metric calculation
• hello mechanism
• election process

Which command will verify that a router that is running OSPFv3 has formed an adjacency with other routers in its OSPF area?

• show ipv6 ospf neighbor
• show ipv6 route ospf
• show ipv6 interface brief
• show running-configuration
