Exam N10-009 Topic 2 Question 299 Discussion

Actual exam question for CompTIA's N10-009 exam
Question #: 299
Topic #: 2
Users 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?

Suggested Answer: A Vote an answer

If a ping to 10.0.100.19 is unreachable, the most likely issue is that users are on the wrong subnet and cannot communicate with the server.
Breakdown of Options:
A:The users are on the wrong subnet. # Correct answer. If users are on a different subnet without proper routing, they won't reach the server.
B:The DHCP server renewed the lease. - Would change the client's IP, but the server's static IP should remain unchanged.
C:The IP address was not reserved. - DHCP reservations matter for dynamic IPs, but RDP servers typically have static IPs.
D:The hostname was changed. - Would affect DNS resolution, but pinging the IP directly would still work.
