The statement is true. The temporary disk in Azure is used primarily for storing data that is temporary in nature, such as page files, swap files, or other transient data that can be lost without impacting the overall operation of the virtual machine.

The primary characteristic of a temporary disk is that it is ephemeral, meaning the data it holds can be lost during various scenarios, including maintenance events or when a virtual machine (VM) is redeployed. When a VM is deallocated or when there is underlying hardware maintenance, the temporary disk may not retain its data, making it unsuitable for critical or persistent storage needs.

This understanding is key in designing applications and services in Azure. It’s crucial to store important data on durable storage solutions such as Azure Disks, Azure Blob Storage, or other persistent data stores to ensure data integrity and availability during such events.
