You have a public-facing SharePoint 2010 site. The site resides on two Web front-ends that
are not load balanced. You are asked to design an update for a Web Part to the site. The
update requires modifications to the code in the global assembly cache (GAC). You need to
design the update with minimal impact to users who are accessing the site. Which approach
should you recommend?

A.
Deploy the update within a custom Microsoft Windows Installer package that copies the
code into the GAC and performs an IISReset on each Web front-end.

B.
Deploy the update in a SharePoint solution file.

C.
Deploy the update directly to the GAC. Recycle the application pool for the SharePoint
site on each Web front-end.

D.
Deploy the update directly to the GAC. Perform an IISReset on each Web front-end.
