Which of the following actions allows the indicator to be saved but takes no action?

The action that allows the indicator to be saved without taking any further action is represented by the choice associated with "No Action." When selecting this option, you ensure that the indicator is recorded and can be reviewed or referenced later, but it does not actively influence the system's response or security posture at that moment. This can be beneficial for scenarios where you want to monitor potential threats without interrupting normal operations, such as when you're still assessing the validity or impact of the indicator.

In contrast, the other options involve varying degrees of active intervention, where either blocking or allowing the traffic could affect system performance or security enforcement immediately. Detect Only might log the behavior for observation but is also more proactive than simply saving the data without an immediate action. Overall, choosing "No Action" is focused on preserving information without engaging automatically with the system's security responses.
