How many previous versions of policies does the PCE keep for better performance?

The correct choice is based on the capacity of the Policy Compute Engine (PCE) to store historical data for policy management, which is essential for maintaining performance and facilitating rollback if needed. The PCE retains 1,000 previous versions of policies. This allows organizations to track changes over time, revert to prior configurations if necessary, and analyze the effect of policy changes on their environment.

Having a substantial number of stored policies enhances operational flexibility, as teams can investigate past policies when troubleshooting or optimizing configurations. Maintaining this historical context is crucial in ensuring that organizations can react swiftly and effectively to unexpected issues that might arise from changes to their security policies. This aspect of policy management aligns with best practices in governance, risk, and compliance within cybersecurity frameworks, emphasizing the importance of data retention for both historical analysis and operational continuity.
