Microsoft Azure Data Fundamentals — Question 154

Blob rehydration occurs in Azure Blob storage when a blob moves between which access tiers?

Answer options

• A. Hot to Cool
• B. Hot to Archive
• C. Cool to Archive
• D. Archive to Cool

Correct answer: D

Explanation

Blob rehydration happens when moving a blob from the Archive tier to the Cool tier, as this process involves making the data accessible again. The other options either involve transitions that do not require rehydration or involve tiers where data is already accessible.
