CIS 225 Unit 2(Single-Area OSPFv2 Configuration) Quiz

Issue the clear ip ospf process privileged mode command.

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. Configure the network statements. Change the interface priority. Change the OSPFv2 process ID.

default-information originate

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 redistribute connected redistribute static redistribute static subnets

the loopback interface IP address

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 OSPF area ID that is configured on the interface with the highest IP address the loopback interface IP address the IP address of the interface that is configured with priority 0 the highest IP address on the LAN interfaces the highest IP address that is configured on the WAN interfaces

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

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 192.168.1.0 255.255.255.255 area 0 router(config-router)# network 192.168.0.0 0.0.15.255 area 0 router(config-router)# network 192.168.1.0 0.0.0.0 area 0 router(config-router)# network 192.168.1.0 0.0.0.255 area 0

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

What are two features of the OSPF routing protocol? (Choose two.) used primarily as an EGP uses Dijkstra's algorithm to build the SPF tree calculates its metric using bandwidth automatically summarizes networks at the classful boundaries has an administrative distance of 100

The path that includes the fastest cumulative bandwidth links.

What does the SPF algorithm consider to be the best path to a network? The path with the smallest delays. The path with the least number of hops. The path that includes the fastest single bandwidth link. The path that includes the fastest cumulative bandwidth links.

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 identifies the OSPF area. The router ID can be used to break a tie in the election process. The router ID indicates the router priority value. The router ID indicates the highest IPv4 address of all routers that are participating in OSPF routing.

highest priority

What is the first criterion used by OPSF routers to elect a DR? highest priority highest MAC address highest router ID highest IP address

show ip ospf interface

Which command can be used to view the OSPF hello and dead time intervals? show ip ospf route show ip protocols show ip ospf neighbor show ip ospf interface

show ip ospf neighbor

Which command could be used on a router to ensure that an OSPF adjacency is formed with another router? show ip protocols show ip ospf neighbor show ip interface brief show ip ospf interface show ip route

(config-router)# auto-cost reference-bandwidth 1000

Which command, if applied on an OSPF router, would give a Gigabit Ethernet interface a lower cost than a Fast Ethernet interface? (config-if)# ip ospf priority 1 (config-if)# bandwidth 100 (config-if)# ip ospf cost 100 (config-router)# auto-cost reference-bandwidth 1000

the router-id rid command

Which criterion is preferred by the router to choose a router ID? the IP address of the highest configured loopback interface on the router the IP address of the highest active OSPF-enabled interface the router-id rid command the IP address of the highest active interface on the router

subnet mask OSPFv2 type of network hello timer

Which three parameters should match in order for a pair of routers to form an adjacency when running OSPFv2? (Choose three.) interface priority subnet mask OSPFv2 process number router ID hello timer OSPFv2 type of network

show ip protocols

Which verification command would identify the specific interfaces on a router that were configured with the passive-interface command? show ip protocols show ip route eigrp show ip eigrp neighbors show ip interface brief

0.0.0.31

Which wildcard mask would be used to advertise the 192.168.5.96/27 network as part of an OSPF configuration? 0.0.0.31 255.255.255.224 0.0.0.32 255.255.255.223
