CompTIA Network+ (N10-008) — Question 634

A network technician is configuring a new subnet on the distribution switch to support 15 network printers. Which of the following available subnets is the best choice to support all 15 printers on the LAN?

Answer options

• A. 10.1.15.0/27
• B. 10.8.4.0/30
• C. 10.10.8.0/28
• D. 10.15.1.0/29

Correct answer: A

Explanation

The correct answer is A, as a /27 subnet provides 32 IP addresses, which is sufficient to accommodate 15 printers while allowing for additional devices. Option B, with a /30 subnet, only offers 2 usable addresses, which is inadequate. Option C, a /28 subnet, provides only 16 addresses, which can accommodate the printers but does not leave much room for future expansion. Option D, with a /29 subnet, provides only 6 usable addresses, making it unsuitable for the requirement.
