Microsoft Azure Architect Design (AZ-304) Practice Test

What is the most effective storage solution for files that must be accessed within 24 hours and cost minimized?

1. Create a v2 storage account set to the Cool access tier.

2. Create a v1 storage account set to the Hot access tier.

3. Create a v2 storage account set to the Hot access tier and set each file to Archive access.

4. Create a Cool access tier storage while maintaining a Hot access tier blob.

The correct answer is: Create a v2 storage account set to the Cool access tier.

The most effective storage solution in this scenario focuses on the requirement for quick access to files within a 24-hour timeframe while also prioritizing cost efficiency. The Cool access tier in a v2 storage account is designed for data that is infrequently accessed but still needs to be available when required. Choosing the Cool access tier allows for lower storage costs compared to the Hot access tier, which is intended for frequently accessed data. In contrast, while the Hot access tier offers immediate access, it incurs higher costs for storage, making it less suitable if cost minimization is a primary concern. Using a v2 storage account provides greater flexibility and features, such as better performance and improved data management capabilities compared to a v1 account. This aligns well with the need for effective storage solutions that balance accessibility with cost. Creating a Cool access tier storage while maintaining a Hot access tier blob, as mentioned in one of the alternatives, would complicate the storage strategy without offering significant cost savings or meeting the demand for quick access, as it mixes tiers unnecessarily. The option that suggests a v2 storage account set to Hot access tier and then attempts to set files to Archive access is also not feasible since Archive access is designed for data that is rarely accessed, contradicting the requirement
