Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 336

You want to implement AAA on router R1 for a more robust authentication and authorization system. What is typically the first global command used to do this?

Answer options

• A. aaa new-model
• B. aaa enable
• C. aaa server-group
• D. aaa authentication login

Correct answer: A

Explanation

The command 'aaa new-model' is essential as it activates the AAA framework on the router, allowing for further configurations of authentication, authorization, and accounting. The other options either refer to specific functionalities or commands that cannot be executed until AAA is enabled with 'aaa new-model'.
