Difficulty: EasyAuthentication, Authorization, and Accounting (AAA)

An IT security administrator is implementing the Authentication, Authorization, and Accounting (AAA) framework for remote access connections. Which of the following tasks directly represent the Accounting component of AAA? (Select TWO.)

  1. Logging user session duration and total network data volume transferredAnswer
  2. Recording login timestamps and authentication attempt outcomes in an audit repositoryAnswer
  3. C
    Validating user credentials using a multi-factor authentication token
  4. D
    Granting read and write permissions to specific network shares based on group policy

Answer

Logging user session duration and total network data volume transferred, and recording login timestamps and authentication attempt outcomes in an audit repository.
Accounting focuses on tracking user activity, auditing actions, and measuring resource consumption such as connection duration, transferred bytes, and login history logs.

Step-by-Step Solution

1
Define the primary responsibility of each AAA pillar
Authentication verifies identity, Authorization determines permissions, and Accounting logs actions, session metrics, and audit histories.
Understanding the distinct boundaries of AAA components allows proper classification of administrative tasks.
2
Evaluate each task option against the Accounting definition
Logging resource usage (session length, byte counts) and keeping audit logs (login timestamps) fall under Accounting. Credential verification falls under Authentication, while permission enforcement falls under Authorization.
Accounting is explicitly responsible for telemetry, data tracking, and historical audit trails.
