Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which of the following is NOT a data storage tier?

1. Archived

2. Warm

3. Hot

4. Cold

The correct answer is: Warm

The concept of data storage tiers is essential for managing data efficiently in cloud environments like Azure. Storage tiers are designed to help organizations store their data based on how frequently it will be accessed and the cost associated with that access. The correct answer, which is identified as "Warm," is noteworthy because the recognized tiers in Azure's data storage context are Hot, Cool, and Archive. The Hot tier is for data that is accessed frequently, while the Cool tier is intended for data that is infrequently accessed but still needs to be readily available. The Archive tier is suitable for data that is rarely accessed and can tolerate higher access times and costs. In this context, "Warm" does not represent an official storage tier in Azure's offerings, which is why it stands out in the list. Understanding these tiers helps users optimize the storage of their data according to its usage patterns, cost factors, and access requirements, ultimately leading to better management of resources and expenses.
