The correct answer is to document the finding and move on, and then report it to the client with a recommendation for a follow-up engagement if needed. This aligns with proper time management as it allows the penetration tester to acknowledge the discovery but also prioritizes the completion of the scope within the given time frame. If there is time left after initial goals are completed, the tester may opt to delve deeper into the vulnerability. Continuing the investigation immediately, or disregarding the finding to focus on initial goals, both risk either overextending the timeline or failing to alert the client to a potentially significant risk, both of which are poor time management practices.
