Which of the following is TRUE with regards to Azure Disk Encryption for a Windows VM?

Azure Disk Encryption for Windows Virtual Machines is designed to enhance data security by encrypting the operating system and data disks. The correct answer highlights that it is supported for standard tier VMs, which reflects Microsoft Azure's configurations for offering encryption. Standard tier VMs are equipped with performance and features that meet the requirements for disk encryption, allowing users to secure sensitive data effectively.

The use of Azure Disk Encryption on standard tier VMs benefits from robust performance characteristics, making it suitable for enterprise applications and workloads requiring enhanced security measures. This layer of encryption is crucial for complying with company policies or regulatory requirements, ensuring that data at rest is protected.

In contrast to the standard tier, basic tier VMs do not typically offer the same range of functionalities or performance needed for effective disk encryption. Additionally, configurations such as software-based RAID systems or Storage Spaces Direct (S2D) might introduce complexities or performance implications that are not officially supported for Azure Disk Encryption, emphasizing why the focus on standard tier VMs is the correct context for this feature.
