Actual exam question for CompTIA's 220-1202 exam
Question #: 70
Topic #: 1

A software vendor releases an emergency "out-of-band" patch to address a critical zero-day vulnerability that could allow remote code execution on all corporate workstations. The IT manager is concerned about the security risk but also wants to ensure that the patch does not cause widespread system crashes or application incompatibility. Which of the following is the BEST course of action for the technician to take?

A. Wait until the next monthly patch is issued and deploy it with those updates. B. Immediately deploy the patch to all company-owned computers. C. Delay the patch deployment to not interfere with the production environment. D. Deploy the patch to a small number of computers in order to test it in a lab.

Suggested Answer: D Vote an answer

A patch released outside the normal schedule for a critical flaw is an out-of-band update, but proper operational procedure still requires controlled testing before broad production rollout. Quentin Docter explains that vendors release patches "usually every month and sometimes outside of the normal release cycle," and that " out-of-band patches " are often responses to " a critical vulnerability ." Because an urgent patch can also cause outages or incompatibilities, you should validate it in a safe environment first. Docter's change management best practices emphasize sandbox testing: " Sandbox testing is extremely useful when you want to test a change before placing it into production ." The All-in-One guide defines sandbox testing as using an isolated environment to test changes " without putting the systems and data you depend on at risk ," typically via virtualization/snapshots. That aligns exactly with deploying to a small pilot group/lab first.
So the best first action is to test the patch on a limited set of systems in a lab/pilot (D), then expand deployment after validation and rollback planning.
