A firewall is experiencing intermittent drops on a specific interface, and the administrator sees 'interface down' messages in the system log, but the interface is currently up. The administrator suspects a flapping interface. What is the MOST likely cause of this runtime issue?

The interface is configured with the wrong IP address

The interface is administratively down

A faulty network cable or a bad SFP module is causing the interface to go up and down

The security policy is blocking traffic on the interface

A firewall is experiencing intermittent packet loss on a specific interface. The administrator checks the interface counters and sees 'rx errors' increasing. The administrator suspects a duplex mismatch. What is the MOST systematic next step to confirm this diagnosis?

Check the interface's negotiated speed and duplex settings and compare them with the connected switch port

Disable the interface and re-enable it to force renegotiation

Replace the network cable to rule out a physical issue

Reboot the firewall to reset the interface counters
