Why each option
In the AAA security framework, Authorization determines what an authenticated user is permitted to access, providing filtered access to resources based on identity and policy.
Providing redundancy is not a function of any AAA component; AAA is a security access control framework, not a high-availability mechanism.
Measuring usage against an identity describes Accounting, which logs and tracks user activity, session duration, and resource consumption for auditing and billing.
Authorization is the AAA component responsible for determining what resources or actions a verified user is allowed to access. It applies policy rules to filter user access, ensuring users can only reach the specific systems, data, or functions they are explicitly permitted to use after authentication.
Ensuring the correct identity describes Authentication, the first A in AAA, which verifies that a user is who they claim to be before any access is granted.
