CCNA: Cisco Certified Network Associate — Question 358

The service password-encryption command is entered on a router. What is the effect of this configuration?

Answer options

• A. restricts unauthorized users from viewing clear-text passwords in the running configuration
• B. prevents network administrators from configuring clear-text passwords
• C. protects the VLAN database from unauthorized PC connections on the switch
• D. encrypts the password exchange when a VPN tunnel is established

Correct answer: A

Explanation

The service password-encryption command secures the router's configuration by encrypting passwords, thus preventing unauthorized users from viewing them in clear text. The other options are incorrect because this command does not restrict administrators from configuring clear-text passwords, does not protect the VLAN database, and is unrelated to VPN tunnel password exchanges.
