CompTIA Network+ Question A-32

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?

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: B

Explanation:
PC 1 cannot connect to Server A. PC 1 and Server A are on different subnets that are connected by Router A. PC 1 can connect to Router A; therefore there is no problem with the link or IP address configuration between PC 1 and Router A.
PC 2, which is on the same subnet as Server A, can connect to Server A; therefore Server A is up.
As PC 1 can connect to Router A but cannot connect to Server A, and Server A is up; the problem must be the connection (link) between Router A and Server A.
