HOTSPOT
You have a SharePoint Server 2013 server farm. The farm contains the following servers:
Six front-end Web servers
Four application servers
Four databases servers
All of the databases in the farm are mirrored by using Microsoft SQL Server database mirroring.
The farm contains the following service applications:
PerformancePoint Service Application
Managed Metadata Service
The PerformancePoint Service Application is configured as shown in the PerformancePoint exhibit. (Click
the Exhibit button.)
The Managed Metadata Service application is configured as shown in Managed Metadata exhibit. (Click
the Exhibit button.)
Select Yes if the statement can be shown to be true based on the available information; otherwise select
No.
Answer: 
I think the third item should be yes, since no alternate database server is configured. A SQL Server failover cluster is referred to by a single name. If you don’t want to change the service applicaton configuration, you must create a SQL Server Failover Cluster.
PerformancePoint Services database supports both synchronous mirroring with SQL 2008 R2 & 2012, and asynchronous mirroring or log-shipping with SQL 2008 R2
