Azure Disk Encryption requires an Azure Key Vault to control and manage disk encryption keys and secrets.
https://docs.microsoft.com/en-us/azure/virtual-machines/windows/disk-encryption-overviewTo encrypt VM1 using Azure Disk Encryption, you must create an Azure Key Vault before proceeding with the encryption process. The correct answer is B. an Azure Key Vault.
Azure Disk Encryption helps protect the data on your virtual machine disks by encrypting them using industry-standard encryption technology. It uses a cryptographic key to encrypt and decrypt the data. Azure Key Vault is a cloud-based service that safeguards cryptographic keys and secrets used by cloud applications and services.
When you enable Azure Disk Encryption for a virtual machine, the encryption process requires a key to encrypt the disks. This key is securely stored in Azure Key Vault. Azure Key Vault provides centralized key management and allows you to control access to keys and secrets, ensuring strong security for your data.
To enable Azure Disk Encryption, the following steps are typically involved:
Create an Azure Key Vault: Before you can encrypt a virtual machine, you need to create an Azure Key Vault. The Key Vault will store the encryption keys securely. You can create a Key Vault using the Azure portal, Azure CLI, Azure PowerShell, or programmatically using the Azure SDKs.
Configure Key Vault access policies: After creating the Key Vault, you need to configure access policies to allow the virtual machine to access the encryption keys stored in the Key Vault. Access policies determine which users or applications can perform specific operations on the keys.
Enable Disk Encryption for the virtual machine: Once the Key Vault is set up, you can enable Azure Disk Encryption for the virtual machine. This can be done through the Azure portal, Azure CLI, Azure PowerShell, or using Azure Resource Manager templates.
During the encryption process, the Azure Disk Encryption extension running on the virtual machine communicates with the Key Vault to retrieve the encryption key. The encryption key is then used to encrypt the data on the virtual machine disks.
In summary, to encrypt VM1 using Azure Disk Encryption, you need to create an Azure Key Vault first to securely store the encryption keys.
The correct answer is B. an Azure Key Vault.
Azure Disk Encryption is a feature that helps you encrypt your Windows and Linux IaaS virtual machine disks. Azure Disk Encryption leverages the industry-standard BitLocker feature of Windows and the DM-Crypt feature of Linux to provide volume encryption for the OS and the data disks. To use Azure Disk Encryption, you need to create and manage encryption keys securely.
You can use Azure Key Vault to securely store and manage the encryption keys used to encrypt the virtual machine disks. Azure Key Vault helps you safeguard keys and secrets by using industry-standard algorithms, key lengths, and HSMs (Hardware Security Modules).
Therefore, before you can encrypt a virtual machine using Azure Disk Encryption, you must create an Azure Key Vault to securely store the encryption keys that will be used to encrypt the virtual machine disks. Once you have created the Azure Key Vault, you can then configure Azure Disk Encryption for the virtual machine and specify the Azure Key Vault to be used to store the encryption keys.
