CompTIA Network+ (N10-008) — Question 187

A network administrator is given the network 80.87.78.0/26 for specific device assignments. Which of the following describes this network?

Answer options

• A. 80.87.78.0 - 80.87.78.14
• B. 80.87.78.0 - 80.87.78.110
• C. 80.87.78.1 - 80.87.78.62
• D. 80.87.78.1 - 80.87.78.158

Correct answer: C

Explanation

The correct answer is C, as a /26 subnet provides a range of 64 IP addresses, allowing for host addresses from 80.87.78.1 to 80.87.78.62, with 80.87.78.0 as the network address and 80.87.78.63 as the broadcast address. Options A and B fall outside the valid range, and option D exceeds the maximum host address for this subnet.
