JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2024) — Question 45

You are deploying an 802.1X solution and must determine what would happen if clients are unable to re-authenticate to the RADIUS server.
In this scenario, which configuration would provide access to the network if the supplicant is already authenticated?

Answer options

• A. move
• B. permit
• C. deny
• D. sustain

Correct answer: D

Explanation

The correct answer is D, 'sustain', because it allows access to the network for clients that have already been authenticated, even if they cannot re-authenticate. Options A, B, and C would either change the client's status or completely deny access, which does not meet the requirement of maintaining access for already authenticated supplicants.
