CompTIA Network+ (N10-009) — Question 309

A network engineer configures the network settings in a new server as follows:

IP address = 192.168.1.15 -

Subnet mask = 255.255.255.0 -

Gateway = 192.168.1.255 -

The server can reach other hosts on the same subnet successfully, but it cannot reach hosts on different subnets. Which of the following is most likely configured incorrectly?

Answer options

• A. Subnet mask
• B. Gateway
• C. Default route
• D. IP address

Correct answer: B

Explanation

The most probable issue is with the Gateway configuration. The gateway address should be within the same subnet range, typically an address like 192.168.1.1 or similar, rather than 192.168.1.255, which is a broadcast address. The other options, such as the subnet mask and IP address, are correctly set for the given network, allowing local communication.
