A storage account contains 5,000 blobs accessed by many users. To ensure users can view only specific blobs based on blob index tags, what should you include in the solution?

A role assignment condition is the correct choice because it allows you to refine access to specific blobs based on their index tags. This feature integrates with Azure RBAC, enabling fine-grained, attribute-based access control. You can define conditions that grant access only if a blob's index tags match specified values, directly addressing the requirement to view only specific blobs based on blob index tags. A stored access policy defines permissions and an expiry for a SAS, but doesn't filter access based on blob index tags. Just-in-time (JIT) VM access is for securing administrative access to virtual machines, not for controlling access to storage blobs. A shared access signature (SAS) provides delegated access to resources, but without a role assignment condition, it doesn't inherently filter access based on blob index tags for multiple users dynamically.
