CompTIA Network+ (N10-009) — Question 493

Users can usually use RDP to connect to a terminal server with hostname TS19 that points to 10.0.100.19. However, users recently have been unable to connect to TS19. The technician pings 10.0.100.19 and gets an unreachable error. Which of the following is the most likely cause?

Answer options

• A. The users are on the wrong subnet.
• B. The DHCP server renewed the lease.
• C. The IP address was not reserved.
• D. The hostname was changed.

Correct answer: C

Explanation

The correct answer is C because if the IP address was not reserved, it could have been assigned to another device, resulting in connectivity issues. Option A is incorrect as it does not explain the unreachable error when pinging the specific IP. Option B is irrelevant in this context since lease renewal does not typically cause reachability issues, and option D does not apply since the hostname change would not affect the ability to ping the IP address directly.
