Which of the following are examples of secure network protocols? (Choose two)

The correct answer is A. SSH B. HTTPS. SSH (A) and HTTPS (B) are correct because both encrypt data in transit - SSH uses asymmetric cryptography to secure remote shell sessions, while HTTPS wraps HTTP inside TLS/SSL to protect web traffic. FTP (C) transmits data and credentials in plaintext, making it trivially…

Explanation

SSH (A) and HTTPS (B) are correct because both encrypt data in transit - SSH uses asymmetric cryptography to secure remote shell sessions, while HTTPS wraps HTTP inside TLS/SSL to protect web traffic. FTP (C) transmits data and credentials in plaintext, making it trivially interceptable. Telnet (D) similarly sends everything unencrypted, including passwords, over the wire.

Memory tip: Think "S = Secure" - the protocols with an S in their name (SSH, HTTPS) are the encrypted ones, while the older protocols without it (FTP, Telnet) predate modern security practices and should be avoided on any network you care about.
