You have a SharePoint Server 2010 server farm.

From the Health Analyzer list, you discover the following messages in the Availability category: “Database has large amounts of unused space.”

You need to reduce the amount of unused space in the database.

Which tool should you use?

A.
Central Administration

B.
Microsoft SQL Server Management Studio

C.
psconfig.exe

D.
stsadm.exe

Explanation:
BURGOS MNEMO: “amount of unused space” = “Central Administration”

@Askin explanation:
because you can shrink database directly from CA.
Microsoft like to show us that everything can be configured directly from administration, without need to install SQL Management Studio.
