OSPF_5.2

Identify command is used to manually configure a router ID in OSPF.

• #ip ospf router-id 1.1.1.1

• #router-id 1.1.1.1

• #router ospf 10 #router-id 1.1.1.1

• #ospf router-id 1.1.1.1

Choose the correct wildcard mask to enable OSPF for network 10.1.1.0/30

• 0.0.0.0
  

• 0.0.0.255

• 0.0.0.3

• 255.255.255.252

Identify the commands enables OSPF directly on an interface.

• router ospf 10
  
  

• ip ospf 10 area 0

• network 10.1.1.0 0.0.0.3 area 0

• ospf enable

Relate the result of configuring ip ospf network point-to-point on an interface

• Disables OSPF on the interface
  

• Prevents Hello packets from being sent

• Disables DR/BDR election on that link

• Converts the link to stub area

Identify the OSPF command is used to advertise a default route into the OSPF domain

• default-route propagate

Select command resets the OSPF process to apply a new router ID.

• restart ospf
  

• clear ip routing

• clear ip ospf process

• reload ospf

In a multiaccess network, which router becomes the DR if all priorities are equal?

• The first router powered on
  
  

• The router with the lowest IP address

• The router with the lowest router ID

• The router with the highest router ID

Identify the purpose of a loopback interface when used in OSPF

• To test connectivity only
  

• To provide a stable router ID

• To simulate DR/BDR election

• To reduce routing table size

What state is shown between two DROTHER routers on a broadcast OSPF network?

• FULL/DR
