Community Answer: A

AAA stands for Authentication, Authorization and Accounting.
✑ Authentication: Specify who you are (usually via login username & password)
✑ Authorization: Specify what actions you can do, what resource you can access
✑ Accounting: Monitor what you do, how long you do it (can be used for billing and auditing)
An example of AAA is shown below:
✑ Authentication: ג€I am a normal user. My username/password is user_tom/learnforeverג€
✑ Authorization: ג€user_tom can access LearnCCNA server via HTTP and FTPג€
✑ Accounting: ג€user_tom accessed LearnCCNA server for 2 hoursג€. This user only uses ג€showג€ commands.
