CCNA 200-125 Exam: Security Questions With Answers

Question 1. Which statement about RADIUS security is true?
A. It supports EAP authentication for connecting to wireless networks.
B. It provides encrypted multiprotocol support.
C. Device-administration packets are encrypted in their entirety.
D. It ensures that user activity is fully anonymous.

Answer: A
RADIUS provides authentication, authorization, and accounting (AAA) services in network environments. When users attempt to access a network device, a RADIUS server verifies that the user is legitimate (authentication). The RADIUS server can then assign certain levels of access to network resources (authorization). Finally, the RADIUS server keeps track of how long that user stayed connected and how much data the user sent or received (accounting).
