Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 51

An administrator is troubleshooting an endpoint that is supposed to bypass 802.1X and use MAB. The endpoint is bypassing 802.1X and successfully getting network access using MAB, however the endpoint cannot communicate because it cannot obtain an IP address.
What is the problem?

Answer options

• A. The endpoint is using the wrong protocol to authenticate with Cisco ISE.
• B. The 802.1X timeout period is too long.
• C. The DHCP probe for Cisco ISE is not working as expected.
• D. An ACL on the port is blocking HTTP traffic.

Correct answer: B

Explanation

The correct answer is B because a long 802.1X timeout could delay DHCP requests, preventing the endpoint from obtaining an IP address. Options A and C are incorrect since they do not specifically address the issue of IP address acquisition, while D is not relevant to the inability to obtain an IP address in this context.
