CCNA: Cisco Certified Network Associate — Question 42

Which command prevents passwords from being stored in the configuration as plain text on a router or switch?

Answer options

• A. enable secret
• B. enable password
• C. service password-encryption
• D. username cisco password encrypt

Correct answer: C

Explanation

The correct command is 'service password-encryption', which encrypts passwords in the configuration file to enhance security. The other options do not provide encryption for stored passwords; 'enable secret' and 'enable password' set passwords but do not encrypt them, while 'username cisco password encrypt' is not a valid command for encrypting passwords in the configuration.
