A company is about to release a very large patch to its customers. An administrator is required to
test patch installations several times prior to distributing them to customer PCs.
Which of the following should the administrator use to test the patching process quickly and often?

A.
Create an incremental backup of an unpatched PC

B.
Create an image of a patched PC and replicate it to servers

C.
Create a full disk image to restore after each installation

D.
Create a virtualized sandbox and utilize snapshots

Explanation:
Sandboxing is the process of isolating a system before installing new applications or patches on it

so as to restrict the software from being able to cause harm to production systems.
Before the patch is installed, a snapshot of the system should be taken. Snapshots are backups
that can be used to quickly recover from poor updates, and errors arising from newly installed
applications.
