Given the following configuration on a Cisco IOS-XE device:

router ospf 1
 network 10.0.0.0 0.255.255.255 area 0

!

interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
 ip ospf cost 10

!

interface GigabitEthernet0/1
 ip address 10.2.2.1 255.255.255.0

!

Which statement is true about OSPF operation?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

GigabitEthernet0/0 will have an OSPF cost of 10, and GigabitEthernet0/1 will have a default cost based on its bandwidth.

The 'ip ospf cost' command overrides the default cost calculation based on bandwidth. The network command matches both interfaces because they fall under 10.0.0.0/8.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Both interfaces will have an OSPF cost of 10.

    Why it's wrong here

    Incorrect. Only GigabitEthernet0/0 has the explicit cost of 10. GigabitEthernet0/1 will use the default cost based on its bandwidth (e.g., 1 for GigabitEthernet).

  • GigabitEthernet0/0 will have an OSPF cost of 10, and GigabitEthernet0/1 will have a default cost based on its bandwidth.

    Why this is correct

    Correct. The explicit cost applies only to the interface it is configured on. The other interface uses the default cost.

  • Both interfaces will have the same OSPF cost because they are in the same area.

    Why it's wrong here

    Incorrect. OSPF cost is interface-specific and not determined by area membership alone.

  • OSPF will not run on either interface because the network command uses a wildcard mask of 0.255.255.255.

    Why it's wrong here

    Incorrect. The wildcard mask 0.255.255.255 matches all addresses starting with 10.x.x.x, so both interfaces are included.

RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
