The correct answer is B. Detect Mode . Detect Mode is used when an administrator wants visibility into Threat Prevention behavior without immediately enforcing a blocking decision. In troubleshooting and tuning, this is essential because it allows security teams to identify which protections would have triggered, review logs, validate false positives, and adjust profiles or exceptions before moving to full prevention. Check Point’s official troubleshooting guidance for Autonomous Threat Prevention describes Detect Only mode and states that protections set to Prevent allow traffic to pass while continuing to track threats according to the Track setting.

This makes Detect Mode the correct operational mode for safe tuning. It preserves observability while reducing the risk of production disruption during policy validation, IPS profile changes, new blade rollout, or incident investigation. Observe Mode , Display Mode , and Watch Mode are not the Check Point Threat Prevention operating modes used for this purpose in the exam context. In a certification scenario, Detect Mode should be understood as a non-blocking validation state: it logs and tracks what Threat Prevention would have done, but does not stop the connection based on a Prevent action.
