What must be enforced to modify settings for scheduled scanning in a cloned threat protection base policy?

To modify settings for scheduled scanning in a cloned threat protection base policy, the correct action is to enforce the policy on the POLICY BYPASSED tab. When a policy is initially cloned, it may not be active until it is enforced, specifically in this tab. This allows changes made to the cloned policy to take effect within the system, enabling administrators to modify and manage the settings related to scheduled scanning effectively.

Enforcement in this context is essential to ensure that any adjustments to the cloned policy are recognized and applied by the security infrastructure. Until the policy is enforced on the POLICY BYPASSED tab, it remains inactive, meaning that scheduled scans or any of the settings within that policy will not operate as intended, thus not providing the desired level of threat protection.

Other options such as enforcing on the ACTIVE tab pertain to policies that are already in effect, while making changes in the PRIMARY SETTINGS tab could be relevant but does not independently ensure that the modifications are recognized system-wide without enforcement. Deleting and recreating the policy is unnecessary and inefficient when the goal is to make modifications to an existing cloned policy.
