AZ-104 Question 101
Single answerYour company stores large volumes of historical compliance data in an Azure Storage account with very infrequent access requests. The data must remain available but can tolerate several hours of retrieval time when needed. Which storage tier provides the most cost-effective solution for these requirements?
- A
Hot tier
- B
Cool tier
- C
Archive tier
- D
Premium block blob tier
Show answer and explanation
Correct answer: C
Explanation
Because your data is rarely accessed yet must remain available, the archive tier is optimal for cost savings. Archive storage has the lowest cost per GB but requires a rehydration process that can take several hours, which is acceptable in your stated scenario.
- A. Incorrect.
Hot tier is best for data that is frequently accessed, offering quick retrieval times but with higher storage costs.
- B. Incorrect.
Cool tier is suitable for infrequently accessed data that might still require near-immediate retrieval, costing less than the hot tier but more than the archive tier.
- C. Correct.
Archive tier is the lowest-cost option for storing rarely accessed data. It can tolerate several hours for rehydration if access is needed.
- D. Incorrect.
Premium block blob tier is tailored for high-performance scenarios with low latency requirements, making it more expensive than other tiers.
