What happens when new policies are fetched from the PCE due to network issues?

When new policies are fetched from the Policy Compute Engine (PCE) and network issues occur, the system resorts to fallback options to maintain continuous operation. This means that while it may not be able to pull the latest policies due to connectivity problems, it will still function using existing, previously fetched policies or predefined defaults that ensure protection and compliance without interruption.

Fallback options are critical for maintaining operational continuity during network disruptions, as they allow the servers or endpoints to continue adhering to security policies that were in place prior to the network issues. This ensures that operations can proceed without requiring any manual intervention, thus preventing operational downtime and minimizing security risks that could arise from unprotected states.

The other choices do not correctly describe the behavior of the system; policies are not discarded, operations do not come to a complete halt, and there is no need for manual input when fallback options can handle the situation automatically.
