Step-by-step explanation:
The purpose of the Microsoft Entrada ID conditional access policy that is applied to the Azure SQL Database is to restrict access based on the user's network location. The policy ensures that only users connecting from a specific network location (such as a corporate network) are allowed access to the sensitive database data. This is a security measure used to prevent unauthorized access, especially when users may connect from various unsecured locations. While it could indirectly affect the accessibility of the associated web app, the main objective of this policy is to secure the Azure SQL Database data against unauthorized access.
