You can configure Cisco UCS to use multiple authentication services by configuring the following features:
Provider groups
Authentication domains
A provider group is a set of providers that the Cisco UCS accesses during the authentication process. All of the providers within a provider group are accessed in the order that the Cisco UCS provider uses to authenticate users. If all of the configured servers are unavailable or unreachable, the Cisco UCS Manager automatically falls back to the local authentication method using the local username and password.
The Cisco UCS Manager allows you to create a maximum of 16 provider groups, with a maximum of 8 providers allowed per group.
Exam Preparation Tasks
As mentioned in the section “How to Use This Book” in the Introduction, you have a couple of choices for exam preparation: the exercises here, Chapter 20, “Final Preparation,” and the exam simulation questions in the Pearson Test Prep software online.
