CompTIA Network+ (N10-007) — Question 370

Two computers are connected to a multilayer switch, and both can access the corporate file server. The computers cannot talk to one another. Which of the following is MOST likely the cause?

Answer options

• A. Duplex/speed mismatch
• B. ACL misconfiguration
• C. Bad port
• D. Crosstalk

Correct answer: B

Explanation

The correct answer is B, as an ACL misconfiguration can prevent communication between devices on the same network while still allowing access to other resources like a file server. Options A, C, and D do not specifically explain the inability for two devices to communicate with each other if they can still reach the file server.
