In your development environment, you designed new versions of a number of features
currently working in a SharePoint 2010 farm. The features are being used throughout the
farm at all scope levels. You need to meet the following requirements: ·All the features on
the farm must be upgraded to the newest version. .All existing feature instances must be
upgraded to the latest version. .The sites using the features must experience as little
downtime as possible. Which approach should you recommend?

A.
Retract the existing versions of the features. Specify the new version number for each
feature in a new Feature.xml file for each feature. Deploy the features as a new solution
package. Activate the new features only in the locations where they are currently activated.

B.
Deploy all of the features as one solution package to the farm. Specify the new version

number for each feature in the current Feature.xml file for the feature. Activate all of the new
features at the farm level.

C.
Deploy each of the features in its own solution package to the farm. Specify the new
version number for each feature in the current Feature.xml file for the feature. Activate the
new features only in the locations where they are currently activated.

D.
Specify the new version number and any upgrade actions required in each of the
Feature.xml files. Run Feature upgrade as a solution package on the farm.
