- A
S3 Standard: Designed for frequently accessed data with low latency and high throughput.
S3 Standard is the default storage class for frequently accessed data, providing low latency and high throughput.
- B
S3 Intelligent-Tiering: Automatically moves data between access tiers to optimize costs.
S3 Intelligent-Tiering monitors access patterns and moves data to the most cost-effective tier.
- C
S3 Glacier: Long-term archival with retrieval times from minutes to hours.
S3 Glacier is designed for archival data that is accessed infrequently, with retrieval times ranging from minutes to hours.
- D
S3 Standard-IA: Lowest-cost storage class for long-term retention with retrieval times of 12 hours.
Why wrong: Incorrect. This describes S3 Glacier Deep Archive, which has the lowest cost and retrieval times of 12 hours. S3 Standard-IA is for infrequently accessed data requiring rapid access.
- E
S3 Glacier Deep Archive: For data accessed less frequently but requires rapid access when needed.
Why wrong: Incorrect. This describes S3 Standard-IA (Infrequent Access), which is for data accessed less frequently but with rapid access needs. S3 Glacier Deep Archive is for long-term archival with very slow retrieval.
DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Match each AWS storage class to its description.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
S3 Standard: Designed for frequently accessed data with low latency and high throughput.
Correct matches: S3 Standard for frequently accessed data, S3 Intelligent-Tiering for automatic cost optimization, and S3 Glacier for archival. Common confusions involve mixing up Standard-IA and Glacier Deep Archive definitions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
