CompTIA Network+ (N10-006) — Question 53
A user is unable to connect to a server in another building. A technician is troubleshooting the issue and determines the following:
1) Client PC 1 has an IP address if 192.168.10.25/25
2) PC 1 can successfully ping its gateway of 192.168.10.1/25 which is an interface of router A
3) Server A is named 'BLDGBFILESRVR01' and has an IP address of 192.168.10.145/25
4) PC 2 with an IP address of 192.168.10.200/25 can successfully ping server A
However, when PC 1 pings server A, it receives a destination host unreachable responds. Which of the following is the MOST likely cause?
Answer options
- A. Link from touter A to PC 1 are on different subnets
- B. Link from router A to server A is down
- C. Link from PC 1 to router A has duplex issues
- D. Link from server A top PC 2 is down
Correct answer: A
Explanation
The correct answer is A because PC 1 and server A are on the same subnet (192.168.10.0/25), but since PC 1 cannot reach server A, it suggests a subnetting issue. Answers B, C, and D do not apply because PC 1 can reach its gateway and PC 2 can communicate with server A, indicating those links are functioning correctly.
