A lab guest must start each class from a clean state. Changes the previous class made inside the guest must not remain. Which action does that?
Select an answer to reveal the explanation.
Short Explanation
You want the guest put back to the clean photograph before the next group arrives. You revert to that snapshot. Keeping the previous changes, mirroring disks, or joining an industry cloud does not reset the guest.
Full Explanation
Reverting to a clean snapshot returns the guest to the saved state and drops the previous class's changes. That is how each class starts clean. Leaving those changes in place does the opposite. A disk mirror on the host protects disks. It does not reset a guest between classes. A community cloud is a shared cloud model. The lab does not need one in order to revert a snapshot. Exam caveat: revert before students need anything that was saved only inside the guest. A snapshot revert is not a backup of their work. Operational check: make a change, revert, and confirm the change is gone before you seat the next class. Seat the next class only after the guest matches the clean snapshot. Record the result on the ticket.
