You have a SharePoint Server 2010 server farm.

You need to ensure that a user named User1 can manage all of the sites in a site collection.

You must achieve this goal while preventing User1 from managing the SharePoint Recycle Bin.

What should you do?

A.
From Site Settings, configure the site permissions.

B.
From Site Settings, configure the site collection administrators.

C.
From Central Administration, configure the site collection administrators.

D.
From Central Administration, configure the Web Application General Settings.

Explanation:
BURGOS MNEMO: Manage sites WITHOUT "Recycle Bin" = "Site Settings … site collection administrators"

@Kielowski explanation:
I agree, B is the right answer. Why? If you take a domain user and make him Site Collection admin in Site Settings, he can log in and administer the site collection. He CANNOT logon to the CA and enable/disable the recycle bin. If you make him site collection admin through CA, he will be able to logon to the CA and manage the recycle bin at that level.
