Question

Quizplus · Accepted Answer

RADIUS and TACACS are both used for AAA, which stands for authentication, authorization, and accounting. The primary purpose of these protocols is to provide secure access to network resources by verifying the identity of users, controlling their level of access to various resources, and tracking their activity for auditing and billing purposes. Thus, the correct answer is B, which includes all three components of AAA. A, C, and D are incorrect because they either omit one of the AAA components or use a different set of terms.
