I feel like C is more about preventing other types of attacks. I’m not confident it directly relates to sniffer attacks, though.

I practiced a similar question, and I think D makes sense too. Reducing the network range could limit exposure to sniffers.

I’m not entirely sure about B. I think switches do help, but I need to recall if they completely prevent sniffing.

I remember studying that using encrypted protocols is a solid way to protect against sniffers. So, A seems right.
