The main recommendation for EAP-auth is that the round-trip latency between the NAD and the authentication servers not exceed 250 ms.
Here you can find the resiliency testing that was done with Central NAC

Subject: Global Cloud Auth from US tenant
Has anyone had issues running Cloud Auth globally when using a US hosted Central instance. I know Central has no issues with monitoring and management of devices globally from a single Central instance, however I imagine there would be more sensitivity to latency when running Cloud Auth since RADIUS will time out if it takes too long to complete an authentication. I couldn't find any documentation on the requirements here, but what would be the considerations if running cloud auth with EntraID for all sites globally? Any issues?
Thanks
