Explanation

The technician has already eliminated the most common causes: network configuration is correct, the cable tested fine, and a known-good workstation on the same cable reproduces the issue. Since the problem follows the cable/port path rather than any specific machine, the fault lies in the physical environment or network infrastructure at that segment. External interference - such as nearby fluorescent lights, electrical motors, or other EMI sources - can corrupt signals on a copper cable even when the cable itself passes basic continuity tests. This matches the intermittent drop-reconnect pattern. Adding new hardware (A) doesn't address a signal-quality issue. A static IP (B) won't fix a physical-layer problem. Checking logs for port flapping (D) is a valid follow-up but comes after ruling out environmental causes that would explain why the port is flapping in the first place.
