JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 14

You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.
In this scenario, which configuration would you use?

Answer options

• A. single supplicant mode
• B. multiple supplicant mode
• C. single-secure supplicant mode
• D. MAC authentication mode

Correct answer: C

Explanation

The correct answer is C, single-secure supplicant mode, as it is specifically designed to allow only one authenticated device at a time on the port. Option A, single supplicant mode, is similar but may not enforce the same level of security as single-secure supplicant mode. Option B, multiple supplicant mode, allows multiple devices to authenticate, which does not meet the requirement. Option D, MAC authentication mode, focuses on MAC addresses rather than device authentication through supplicants.
