Refer to the exhibit. An administrator needs to disable Cisco Discovery Protocol on the port configured with the last usable address in the 10.0.0.0/30 subnet. Which command set satisfies this requirement?

  • A interface gi0/1no cdp enable
  • B interface gi0/0no cdp run
  • C interface gi0/0no cdp advertise-v2
  • D interface gi0/1clear cdp table
Explanation

The exhibit’s interface addressing shows the intended /30 WAN subnet is 10.0.0.252/30, where the usable host addresses are 10.0.0.253 and 10.0.0.254. The last usable address is 10.0.0.254, which is assigned to Gi0/1. On Cisco IOS, CDP is disabled per interface with the no cdp enable command entered in interface configuration mode. That makes the correct command sequence interface gi0/1 followed by no cdp enable.
