Single-Area OSPFv2 Configuration

Which command, if applied on an OSPF router, would give a Gigabit Ethernet interface a lower cost than a Fast Ethernet interface?

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

0.0.0.31

A network administrator has just changed the router ID on a router that is working in an OSPFv2 environment. What should the administrator do to reset the adjacencies and use the new router ID?

Issue the clear ip ospf process privileged mode command.

What does the SPF algorithm consider to be the best path to a network?

The router ID can be used to break a tie in the election process.

What is one use of the router ID in OSPF routing?

The router ID can be used to break a tie in the election process.

What are two features of the OSPF routing protocol?

calculates its metric using bandwidth uses Dijkstra's algorithm to build the SPF tree

A router in an OSPF enterprise network has a default static route that has been configured via the interface that connects to the ISP. Which command would the network administrator apply on this router so that other routers in the OSPF network will use this default route?

default-information originate

What is the first criterion used by OPSF routers to elect a DR?

highest priority

The following three networks are directly connected to an OSPF router; 192.168.0.0/24, 192.168.1.0/24, and 192.168.2.0/24. Which OSPF network command would advertise only the 192.168.1.0 network to neighbors?

router(config-router)# network 192.168.1.0 0.0.0.255 area 0

Which command can be used to view the OSPF hello and dead time intervals?

show ip ospf interface

Which command could be used on a router to ensure that an OSPF adjacency is formed with another router?

show ip ospf neighbor

Which verification command would identify the specific interfaces on a router that were configured with the passive-interface command?

show ip protocols

Which three parameters should match in order for a pair of routers to form an adjacency when running OSPFv2? (Choose three.)

subnet mask, hello timer, OSPFv2 type of network

A router with two LAN interfaces, two WAN interfaces, and one configured loopback interface is operating with OSPF as its routing protocol. What does the router OSPF process use to assign the router ID?

the loopback interface IP address

Which criterion is preferred by the router to choose a router ID?

the router-id rid command
