Correct answer & explanation
✓
Azure Key Vault integration with Storage Service Encryption
Azure Key Vault integration with Storage Service Encryption. This feature allows ADLS Gen2 to use customer-managed keys stored in Azure Key Vault for encryption at rest. Option B is incorrect because Azure Information Protection is for data classification and labeling, not encryption. Option C is incorrect because Storage Service Encryption with Microsoft-managed keys is the default, but the requirement specifies customer-managed keys. Option D is incorrect because Azure Disk Encryption applies to VM disks, not ADLS Gen2 storage.
