Why should an enterprise categorize applications as part of its secure digital transformation to a...

The correct answer is C. In Zero Trust architecture, applications must be identified, defined, and differentiated so that policy can be applied at a granular level. Zscaler’s Zero Trust User-to-App Segmentation guidance explains that organizations should identify, define, and characterize applications and application segments as part of the move from legacy network-based access to a user-based approach using application segments and access policies. That directly supports the idea that application categorization is necessary to distinguish one destination from another and apply the correct user-to-application policy.

This is important because Zero Trust does not grant broad network access and then rely on downstream controls. Instead, it gives access to the right application for the right initiator under the right conditions. Without meaningful application categorization, organizations cannot create granular segmentation or precise access policies. Naming conventions and CMDB storage may be useful operationally, but they are not the core reason. Likewise, ACL planning belongs to legacy firewall thinking rather than Zero Trust design. Therefore, the strongest architecture-aligned answer is that applications are categorized in order to differentiate destinations and enable granular control from valid initiator to valid destination application.
