The best answer is A. Implementing an update after a board grants approval.

Change management is the formal process used to request, review, approve, test, document, and implement changes to systems and environments in a controlled manner. A common example is submitting a proposed change to a change advisory board (CAB) or other approval authority, receiving approval, and then implementing the update according to procedure.

This answer reflects the structured governance process that Security+ associates with proper change management.

Why the other options are incorrect:

B. Setting a new password for a userThis is a routine administrative or support task, not a formal example of change management.

C. Performing a penetration test before deploying a patchPenetration testing is a security assessment activity. It may support decision-making, but it is not itself the best example of the change management process.

D. Auditing all system equipment before sending the list to the Chief Executive OfficerThis is closer to inventory or audit work, not change management.

From a SY0-701 perspective, change management is about controlled, approved, and documented changes to the environment. Therefore, A is the correct answer.
