NEW QUESTION: 1
Refer to the exhibit.

NEW QUESTION: 2
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 a virtualized sandbox and utilize snapshots
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 an incremental backup of an unpatched PC
Answer: A
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.
Incorrect Answers:
A, C: Creating a full disk image or an incremental backup to restore after each installation could prove useful but less efficient than using snapshots.
B. Replicating a patched PC to all servers does not test the patch, and does not ensure quick recoverability should the patch cause the PC to crash.
