CompTIA Network+ (N10-009) — Question 488

Users report connectivity issues after a network switch is replaced. There are three separate subnets for users, voice, and servers. The users cannot reach the resources in the server subnet. Upon investigation, a separate voice switch has thousands of discarded packets, but no users report issues making or receiving calls. Which of the following is most likely the issue?

Answer options

• A. Incorrect cable
• B. Port administratively disabled
• C. VLAN misconfiguration
• D. Duplex setting

Correct answer: C

Explanation

The correct answer is C, as a VLAN misconfiguration can prevent users from accessing resources on the server subnet while still allowing voice traffic to function normally. The other options, such as an incorrect cable or disabled port, would likely cause more widespread issues rather than isolating connectivity problems to specific subnets.
