JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 44

You are asked to deploy 802.1X on your EX Series switches. You need to ensure authenticated devices continue to have access to the network even if the authentication server fails.
Which action meets this configuration objective?

Answer options

• A. Configure the server fail fallback with a value of sustain.
• B. Set the reauthentication interval to a value of 0.
• C. Configure the static MAC bypass for the authentication server.
• D. Set the reauthentication interval to a value of disable.

Correct answer: A

Explanation

The correct answer is A because configuring the server fail fallback with a value of sustain allows authenticated devices to maintain network access during an authentication server failure. Option B is incorrect because setting the reauthentication interval to 0 does not address server failures. Option C is not suitable as static MAC bypass does not ensure continued access for authenticated devices in this scenario. Option D disables reauthentication, which is not the appropriate solution for maintaining access.
