- A
Transition objects to S3 Standard-IA after 60 days.
Standard-IA reduces storage cost for infrequently accessed objects while still keeping retrieval in minutes, which fits the post-production review period.
- B
Transition objects to S3 Glacier Deep Archive after the review period ends.
Glacier Deep Archive provides the lowest S3 storage cost for long-term retention when retrieval can take hours, matching the oldest files.
- C
Expire objects after 7 years.
Lifecycle expiration at the end of the retention window prevents paying for storage beyond the policy requirement and keeps the design cost efficient.
- D
Store the same files in EBS snapshots instead of S3 to lower archive costs.
Why wrong: EBS snapshots are for block storage backups, not object lifecycle management, and they do not match the access pattern described here.
- E
Replicate the bucket to another Region to reduce storage charges.
Why wrong: Cross-Region replication improves resilience, not storage cost. It also increases cost because it duplicates data and replication traffic.
Quick Answer
The answer is to transition objects to S3 Standard-IA after 60 days, then to S3 Glacier Deep Archive after six months, and finally expire them after 7 years. This sequence directly achieves S3 lifecycle policy cost optimization by matching storage tiers to access patterns: Standard-IA reduces cost for occasional legal reviews while retaining millisecond retrieval, and Glacier Deep Archive provides the lowest-cost storage for the oldest files where retrieval can take hours. On the SAA-C03 exam, this scenario tests your ability to map lifecycle transitions to specific business requirements, with a common trap being choosing Glacier Flexible Retrieval instead of Deep Archive when retrieval time is not critical. Remember the memory tip: “Hot, warm, cold, expire” — heavy access (Standard), occasional access (Standard-IA), archival (Deep Archive), then deletion. This question reinforces that lifecycle policies are the primary tool for automating cost savings without sacrificing compliance or retrieval needs.
SAA-C03 Design Secure Architectures Practice Question
This SAA-C03 practice question tests your understanding of design secure architectures. 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 media company stores raw project files in Amazon S3. Files are accessed heavily for the first 60 days, occasionally for legal review during the next six months, and must be retained for 7 years. Retrieval for the oldest files can take hours. Which three actions should the architect recommend? Select three.

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
Transition objects to S3 Standard-IA after 60 days.
Option A is correct because S3 Standard-IA is designed for data accessed less frequently but requires rapid access when needed. After 60 days of heavy access, transitioning to Standard-IA reduces storage costs while maintaining low-latency retrieval for occasional legal reviews.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Cross-Region replication improves resilience, not storage cost. It also increases cost because it duplicates data and replication traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse S3 replication (which increases costs) with a cost-saving mechanism, or incorrectly assume EBS snapshots are a cheaper alternative for long-term archival, when in fact S3 Glacier Deep Archive is the most cost-effective option for data that can tolerate hours of retrieval time.
Detailed technical explanation
How to think about this question
S3 Lifecycle policies use the `Transition` action to move objects between storage classes based on age. S3 Glacier Deep Archive has a retrieval time of 12–48 hours, which aligns with the requirement that retrieval for the oldest files can take hours. The 7-year expiration uses the `Expiration` action to permanently delete objects, ensuring compliance with retention policies without manual intervention.
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.
TExam Day Tips
- 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.
