Question

Enables global password encryption:

a) enable secret
b) password 7
c) service password-encryption
d) enable password

Answer 1

The command 'service password-encryption' enables global password encryption on a device, encrypting all current and future passwords in the configuration file.

Step-by-step explanation:

The command that enables global password encryption on a device is c) service password-encryption. This command ensures that all current and future passwords are encrypted when they are stored in the configuration file. This encryption does not provide very strong security, but it does prevent passwords from being easily readable. The options a) enable secret and d) enable password refer to setting the privileged exec mode password, but don't encrypt all passwords. b) password 7 specifies the type of password encryption but is not a command that enables global encryption.
