CompTIA A+ Core 1 (220-1101) — Question 531

A technician needs to ensure all data communications on all network devices are encrypted when logging in to the console. Which of the following protocols should the technician enable?

Answer options

• A. SSH
• B. LDAP
• C. FTPS
• D. SMTP

Correct answer: A

Explanation

The correct answer is A, SSH, as it provides a secure channel over an unsecured network by encrypting the data transmitted during login. The other options do not primarily focus on securing console logins: LDAP is for directory services, FTPS is for secure file transfers, and SMTP is used for email transmission.
