Modules 1-2

A network engineer has manually configured the hello interval to 15 seconds on an interface of a router that is running OSPFv2. By default, how will the dead interval on the interface be affected?

• The dead interval will not change from the default value.
• The dead interval will now be 15 seconds.
• The dead interval will now be 30 seconds.
• The dead interval will now be 60 seconds.

A network technician issues the following commands when configuring a router:

R1(config)# router ospf 11
R1(config-router)# network 10.10.10.0 0.0.0.255 area 0

What does the number 11 represent?

• the administrative distance that is manually assigned to R1
• the area number where R1 is located
• the autonomous system number to which R1 belongs
• the cost of the link to R1
• the OSPF process ID on R1

After modifying the router ID on an OSPF router, what is the preferred method to make the new router ID effective?

• HQ# clear ip ospf process
• HQ# clear ip route *
• HQ# copy running-config startup-config
• HQ# resume
