Which statement is correct?

Question

Options

• AClass A is ideal for small networks (20 hosts).
• BClass A is ideal for large networks (70,000 hosts).
• CClass B is ideal for large networks (70,000 hosts).
• DClass C is ideal for middle networks (500 hosts).

• A
  6% (1)
• B
  76% (13)
• C
  6% (1)
• D
  12% (2)

Explanation

Class A reserves 8 bits for the network and 24 bits for hosts, supporting over 16 million hosts per network - making it the only class capable of handling 70,000+ hosts efficiently. Option B is correct because Class A's massive host range makes it purpose-built for very large networks.

Why the distractors fail:

• A is wrong because Class A's enormous host capacity would be wasted on a tiny 20-host network - Class C (up to 254 hosts) fits that scenario perfectly.
• C is wrong because Class B supports up to ~65,534 hosts, which actually falls just short of 70,000, making it unsuitable for that specific requirement.
• D is wrong because Class C maxes out at 254 hosts, so a 500-host network exceeds its capacity; Class B would be the right fit for mid-sized networks in that range.

Memory tip: Think of A/B/C as Large/Medium/Small - Awesome for massive networks, Big-but-not-biggest for medium, Cozy for small. When you see a host count above 65,534, only Class A can handle it.
