Which of the following statements about Peer-to-Peer networks is true?

• A. They require a centralized server
• B. They are always faster than client-server networks
• C. They use cloud infrastructure exclusively
• D. They are best for small networks with few computers

Answer: (D)

Peer-to-Peer networks connect directly between computers, with no dedicated central server coordinating all resources. This approach works well when there are only a few machines because setup is simple and costs are low—you can share files, printers, or other resources directly between devices without configuring and maintaining a separate server.

As networks grow, managing and securing many direct connections becomes more complex, and performance can become unpredictable since there’s no single point of coordination to optimize requests. That’s why P2P isn’t typically favored for large networks.

The statements about needing a centralized server, being always faster, or relying exclusively on cloud infrastructure don’t fit the typical behavior of Peer-to-Peer networks. They don’t require a central server, aren’t guaranteed to be faster, and aren’t limited to cloud use.

So the best description is that Peer-to-Peer networks are best for small networks with few computers, because their simplicity and low cost fit that scale well.
