次の表に示すAzure Key Vaultを含むSub1という名前のAzureサブスクリプションがあります。 Sub1では、次の構成を持つ仮想マシンを作成します。 * Name: VM1 * Size: DS2v2 * Resource group: RG1 * Region: West Europe * Operating system: Windows Server 2016 You plan to enable Azure Disk Encryption on VM1. In which key vaults can you store the encryption key for VM1?
正解:C
"Your key vault and VMs must be in the same subscription. Also, to ensure that encryption secrets don't cross regional boundaries, Azure Disk Encryption requires the Key Vault and the VMs to be co-located in the same region." https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disk-encryption-key-vault
