Correct Answer

Deploy Azure Key Vault with a Private Endpoint in the same VNet as the HANA VM, and configure Key Vault firewall to deny public access

Why This Answer Is Correct

Azure Private Endpoint creates a private IP address in your VNet that maps to the Key Vault. Traffic from the HANA VM to Key Vault stays entirely within the Azure backbone and never traverses the internet. Combined with Key Vault firewall set to deny public network access, this ensures fully private key retrieval. Service Endpoints allow VNet traffic to reach Key Vault via the public endpoint (but over the Microsoft backbone), while Private Endpoints are preferred for stricter isolation. Storing TDE keys in blob is insecure and unsupported.
