CCNA Routing and Switching (legacy) — Question 140

Which statement about RADIUS security is true?

Answer options

• 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.

Correct answer: A

Explanation

Option A is correct because RADIUS does indeed support EAP authentication, which is crucial for wireless network connections. The other options are incorrect as RADIUS does not encrypt all device-administration packets, does not provide full anonymity for user activity, and while it supports various protocols, it does not specifically provide encrypted multiprotocol support.
