A technician is assisting a customer who is experiencing frequent network issues.

The technician should not disclose information about other customers’ issues, environments, or outcomes because that violates professional confidentiality expectations. Instead, the best response is to explain the general troubleshooting process the technician will follow—such as gathering symptoms, checking logs/connection status, isolating whether the problem is local vs. ISP, testing known-good hardware, and documenting results—without referencing other clients’ specific cases. Quentin Docter emphasizes that as a computer professional you must uphold confidentiality and ensure sensitive information “goes no further,” reinforcing that you should not reveal work-related details to others. The All-in-One guide similarly states that anything you see or are told should be treated as a “personal confidence” and not repeated to customers or others, underscoring why option A is inappropriate. Mike Meyers’ Lab Manual echoes this privacy expectation: treat what you see as confidential and handle customers’ private materials appropriately. Option B dismisses the customer’s concern, and option D is unprofessional and speculative.
