Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 95

An administrator adds a new network device to the Cisco ISE configuration to authenticate endpoints to the network. The RADIUS test fails after the administrator configures all of the settings in Cisco ISE and adds the proper configurations to the switch.
What is the issue?

Answer options

• A. The endpoint profile is showing as ''unknown"
• B. The endpoint does not have the appropriate credentials for network access
• C. The certificate on the switch is self-signed, not a CA-provided certificate
• D. The shared secret is incorrect on the switch or on Cisco ISE

Correct answer: D

Explanation

The correct answer is D because the shared secret must match on both the switch and Cisco ISE for authentication to succeed. If the shared secret is incorrect, the RADIUS test will fail. Options A, B, and C may indicate other issues but do not directly relate to the failure of the RADIUS test in this context.
