If you plan for a subnet requiring at least 200 host addresses, would a 192.168.0.0/24 subnet meet the requirement, and why?

• A. No, a /24 supports only 128 host addresses.
• B. Yes, a /24 supports up to 200 host addresses.
• C. Yes, a /24 supports up to 500 host addresses.
• D. Yes, a /24 supports up to 254 host addresses, which exceeds 200.

Answer: (D)

A subnet’s size determines how many hosts it can support. For a /24, there are 2^(32-24) = 256 total addresses. Two addresses are reserved for the network and broadcast, leaving 254 usable host addresses. Since you need at least 200, a /24 provides enough addresses because 254 > 200. The other options either understate the capacity (128 usable addresses) or overstate it (500), while a /24 simply cannot offer 500 usable hosts. Therefore, 192.168.0.0/24 meets the requirement.
