CompTIA Network+ (N10-007) — Question 134

A technician is configuring a new server with an IP address of 10.35.113.47 on the 10.35.112.0 subnet to allow for the maximum number of hosts. When configuring network settings, which of the following is the correct subnet mask?

Answer options

• A. 10.35.112.0/30
• B. 10.35.112.0/24
• C. 255.255.240.0
• D. 255.255.248.0
• E. 255.255.255.0

Correct answer: C

Explanation

The correct subnet mask is 255.255.240.0, which allows for a larger number of hosts by providing a /20 subnet. The other options either provide too few IP addresses for the number of hosts required, such as /30 and /24, or are not as efficient for the given subnet as 255.255.240.0.
