A scheduler wants to try a risky change to an application without the staff seeing it. A separate virtual copy of that application is available. Which use of the copy fits?
Select an answer to reveal the explanation.
Short Explanation
You can try the risky change on the separate virtual copy, using it as a test environment before staff see it. Keep the live application unchanged; a RAID mirror protects disks, and a community cloud is not required to test the change.
Full Explanation
A test environment is a separate copy of an application where you can try a change before users see it. The available virtual copy fits this purpose: apply the risky change there, rather than exposing staff to it on the live application. The live application is the system staff use, so changing it first would put the risk in front of the people the scheduler wants to protect. A RAID mirror protects disks by keeping mirrored disk data; it is not a virtual copy of an application and does not provide an isolated place to try a software change. A community cloud is shared by several organizations, but nothing in this scenario requires that cloud model before an application can be tested. Exam caveat: refresh the test copy from production data carefully, so a test does not email real customers or write back to the live system. Practical check: apply the change only on the virtual copy, confirm the staff application remains unchanged, and promote the change only after the test passes. Also ensure the test copy cannot send mail to real customers.
