When should passwords be allowed to be sent as plain text over a public network?
  1. Never
  2. When the password protected resources are fairly unimportant
  3. When using Secure Shell
  4. When the communications are secured by SSL or TLS
Explanation
Answer: A - Passwords should never be sent as plain text over a public network.

Key Takeaway: Passwords should never be sent over a public network in plain text. Doing so defeats the purpose of having a password. If a resource is password protected, it is important enough to only send the password in a secure way. Secure Shell and SSL/TLS encrypt all communications including passwords.
