Step-by-step explanation:
The correct answer is option b) enable password 7.
In Cisco devices, the command enable password 7 is used to configure an already encrypted password using type 7 encryption.When configuring passwords on Cisco devices, there are two types of encryption commonly used: type 5 and type 7. Type 5 encryption uses the stronger MD5 algorithm, while type 7 encryption is a weaker form of encryption that is reversible.For example, to configure an encrypted password using type 7 encryption, you would enter the command enable password 7 <encrypted_password>, where <encrypted_password> is the encrypted password you want to configure.
