The answer is to set an S3 Lifecycle policy to expire objects after 7 years, combined with transitions to S3 Standard-IA after 30 days and to S3 Glacier Deep Archive after a suitable period. This approach directly addresses the compliance and cost optimization requirements by moving frequently accessed logs to lower-cost infrequent access storage, then to the cheapest archival tier for long-term retention, with a final expiration action to delete the data exactly when the 7-year retention period ends. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your ability to apply multiple lifecycle transitions for compliance and cost without violating retention rules—a common trap is selecting Intelligent-Tiering, which incurs monitoring costs that negate savings for predictable access patterns, or prematurely deleting logs. Remember the memory tip: "Hot to Cold to Grave"—transition from Standard to Standard-IA, then to Glacier Deep Archive, and finally expire at the retention deadline.
SOA-C02 Cost and Performance Optimization Practice Question
This SOA-C02 practice question tests your understanding of cost and performance optimization. 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.
An application writes logs to an S3 bucket. The logs are accessed frequently for the first 30 days, then rarely after that, but must be retained for 7 years. Which THREE steps should be taken to optimize cost? (Choose three.)

Correct answer & explanation
✓
Use an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 90 days.
Options A, C, and E are correct. S3 Lifecycle rules can transition objects to lower-cost storage classes. S3 Standard-IA is for infrequent access, and Glacier Deep Archive is for long-term archiving. Option B is incorrect because Intelligent-Tiering has monitoring costs. Option D is incorrect because deleting logs violates retention requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

Variation 1. A company is using Amazon S3 to store log files. The logs are accessed frequently for the first 30 days and then rarely, but must be retained for 7 years for compliance. Which THREE actions would optimize storage costs while maintaining accessibility?
hard
A.Delete objects older than 90 days.
✓ B.Transition objects to S3 Glacier Deep Archive after 365 days.
✓ C.Create a lifecycle policy to transition objects to S3 Standard-IA after 30 days.
D.Transition objects directly to S3 Glacier after 30 days.
E.Use S3 Intelligent-Tiering to automatically move objects.
Why B: S3 Lifecycle policies automate transitions to lower-cost storage classes. Moving to S3 Standard-IA after 30 days reduces cost for infrequent access. Moving to S3 Glacier Deep Archive after 1 year is cost-effective for long-term retention while still allowing retrieval within hours. Option A is wrong because S3 Intelligent-Tiering incurs monitoring costs and may not be cheapest for predictable access. Option B is wrong because deleting after 90 days violates compliance. Option D is wrong because moving directly to Glacier after 30 days may be too early for infrequent access.
