SOA-C02 Cost and Performance Optimization Practice Question
This SOA-C02 practice question tests your understanding of cost and performance optimization. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company is using Amazon S3 to store data for analytics. The data is accessed frequently for the first 30 days, then rarely after that. The company wants to optimize storage costs. Which THREE actions should the SysOps administrator recommend?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use S3 Intelligent-Tiering to automatically optimize storage costs.
Option B is correct because S3 Intelligent-Tiering automatically moves data between tiers. Option C is correct because lifecycle policies can transition objects to colder storage. Option E is correct because S3 Glacier Deep Archive is the cheapest for long-term archival. Option A is wrong because S3 Standard is more expensive than Standard-IA for infrequent access. Option D is wrong because S3 One Zone-IA is for infrequent access but does not provide high availability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use S3 Intelligent-Tiering to automatically optimize storage costs.
Why this is correct
Intelligent-Tiering moves data between tiers based on access patterns.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
Use S3 One Zone-IA for all data after 30 days to reduce costs.
Why it's wrong here
One Zone-IA is not recommended for data that needs high availability.
✓
Create a lifecycle policy to transition objects to S3 Glacier Deep Archive after 90 days.
Why this is correct
Glacier Deep Archive is the cheapest storage class for archival.

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.
