Selected Answer: D
Troubleshoot Port Flapping Issues Intermittent connectivity might manifest as port flapping , which means that the NIC or switch interface transitions continually between up and down states. This is often caused by bad cabling or external interference or a faulty NIC at the host end. You can use the switch configuration interface to report how long a port remains in the up state.

Port flapping, or link flapping, occurs when a switch's port state goes up and down repeatedly in a short amount of time. It can be caused by bad cables or link synchronization issues.
