CompTIA Server+ (SK0-005) — Question 102

A systems administrator is trying to determine why users in the human resources department cannot access an application server. The administrator reviews the application logs but does not see any attempts by the users to access the application.

Which of the following is preventing the users from accessing the application server?

Answer options

• A. NAT
• B. ICMP
• C. VLAN
• D. NIDS

Correct answer: C

Explanation

The correct answer is C, as a VLAN configuration could be blocking communication between the HR department and the application server. NAT, ICMP, and NIDS do not inherently restrict access based on departmental segmentation like a VLAN does.
