Answer:
Authorization is responsible for determining what a user can and cannot do with network resources.
Explanation:
AAA stands for Authentication , Authorization and Accounting. As the name suggests, Authorization is responsible for what a user can and cannot do with the network resources. Any user should get authorized to get access to the network resources. Every user can have different access levels to all of the network resources. For example, a Network Administrator might have access to all of the network resources ( as the administrator is responsible for all the network resources on the network ) whereas a Developer might have access to only some of the particular network resources.
