What is a characteristic of AAA accounting?

• Possible triggers for the aaa accounting exec default command include start-stop and stop-only.
• Accounting can only be enabled for network connections.
• Accounting is concerned with allowing and disallowing authenticated users access to certain areas and programs on the network.
• Users are not required to be authenticated before AAA accounting logs their activities on the network.

Explanation: AAA accounting enables usage tracking, such as dial-in access and EXEC shell session, to log the data gathered to a database, and to produce reports on the data gathered. Configuring AAA accounting with the keyword Start-Stop triggers the process of sending a "start" accounting notice at the beginning of a process and a "stop" accounting notice at the end of a process. AAA accounting is not limited to network connection activities. AAA accounting is in effect, if enabled, after a user successfully authenticated. Allowing and disallowing user access is the scope of AAA authorization.
