What is the role of real-time updates in Application Control and URL Filtering?

The correct answer is A. Application Control and URL Filtering depend on accurate identification and categorization of applications, sites, and URL categories. Real-time or regularly updated classification data helps ensure that new applications, changed SaaS services, new domains, and updated web categories are recognized correctly. Option B is wrong because gateway-to-gateway encryption is VPN/IPsec functionality, not Application Control or URL Filtering updates. Option C is wrong because user authentication and identity mapping are handled by Identity Awareness sources such as AD Query, Browser-Based Authentication, Identity Collector, RADIUS Accounting, Identity Agents, or Identity Web API. Option D is wrong because updated categorization does not remove the need for HTTPS Inspection; encrypted traffic may still require inspection or metadata-based categorization for accurate enforcement. The core value of updates is classification accuracy, which directly affects policy matching, blocking, allowing, and logging.
