CompTIA Network+ (N10-009) — Question 34

A network administrator configured a router interface as 10.0.0.95 255.255.255.240. The administrator discovers that the router is not routing packets to a web server with IP 10.0.0.81/28. Which of the following is the best explanation?

Answer options

• A. The web server is in a different subnet.
• B. The router interface is a broadcast address.
• C. The IP address space is a class A network.
• D. The subnet is in a private address space.

Correct answer: B

Explanation

The correct answer is B because the IP address 10.0.0.95 falls within the range of the broadcast address for the subnet defined by the mask 255.255.255.240, which is 10.0.0.95 to 10.0.0.111. Therefore, the router cannot route packets correctly. Option A is incorrect since both IPs belong to the same subnet; option C is irrelevant to the routing issue; option D does not affect routing functionality.
