The correct answer is B. FastEthernet0/1 C. Serial0/0 D. Serial0/1.102. The network statement 'network 192.168.12.64 0.0.0.63 area 0' uses wildcard mask 0.0.0.63, which corresponds to a /26 prefix. This matches any IP address in the range 192.168.12.64 through 192.168.12.127. Based on the exhibit, the interfaces with IP addresses falling within this

Question

Refer to the exhibit. A network associate has configured OSPF with the command: City(config-router)# network 192.168.12.64 0.0.0.63 area 0 After completing the configuration, the associate discovers that not all the interfaces are participating in OSPF. Which three of the interfaces shown in the exhibit will participate in OSPF according to this configuration statement? (Choose three.)

Options

  • AFastEthernet0/0
  • BFastEthernet0/1
  • CSerial0/0
  • DSerial0/1.102
  • ESerial0/1.103
  • FSerial0/1.104

Explanation

The network statement 'network 192.168.12.64 0.0.0.63 area 0' uses wildcard mask 0.0.0.63, which corresponds to a /26 prefix. This matches any IP address in the range 192.168.12.64 through 192.168.12.127. Based on the exhibit, the interfaces with IP addresses falling within this range are FastEthernet0/1, Serial0/0, and Serial0/1.102. FastEthernet0/0's IP address falls outside this range, and Serial0/1.103 and Serial0/1.104 also fall outside the 192.168.12.64–.127 range, so those three interfaces do not participate in OSPF under this statement.
