Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 150

A network engineer needs to deploy 802.1x using Cisco ISE in a wired network environment where thin clients download their system image upon bootup using PXE. For which mode must the switch ports be configured?

Answer options

• A. closed
• B. restricted
• C. monitor
• D. low-impact

Correct answer: D

Explanation

The correct answer is D, low-impact, because this mode allows devices like thin clients to boot and download images via PXE while still enforcing 802.1x authentication. The other modes, such as closed and restricted, would prevent the devices from accessing the network until authentication is complete, which is not suitable for PXE booting.
