You have a SharePoint Server 2013 server farm that uses several back-end data sources.
The
back-end data sources require authentication. You create a Secure Store Service
application. The farm does not have a PerformancePoint Services service application.
Security requirements in your organization prevent the use of Kerberos delegation. You
plan to implement a new PerformancePoint Services service application. You need to
ensure that all new PerformancePoint Services dashboards can successfully access the
back-end data sources. How should you configure thePerformancePoint Services service
application?

A.
Configure the Unattended Service Account setting.

B.
Configure an application pool that has access to the back-end data sources.

C.
Enable the PerformancePoint Services site and site collection features.

D.
Enable the Add this service application’s proxy to the farm’s default proxy list setting.

Explanation:
In order to use PerformancePoint Services in Microsoft SharePoint Server 2013, you must configure a
PerformancePoint Services service application. Onceyou have created the service application, you must
provide data access to the users. This can be done by using the unattended service account, or by configuring
Kerberos delegation.
The Unattended Service Account is an Active Directory account that is used for accessing PerformancePoint
Services data sources. This account is used by PerformancePoint Services on behalf of authorized usersto
provide access to external data sources for the purposes of creating and using dashboards and other
PerformancePoint Services content.
