- A
Transition the objects to S3 Standard-IA after 30 days.
Standard-IA is a good fit after the initial hot period because retrievals become less frequent but still matter. It reduces storage cost compared with S3 Standard while keeping the data quickly accessible for the next several months.
- B
Transition the objects to S3 Glacier Deep Archive after 120 days.
Deep Archive is the lowest-cost storage class for long-term retention when access becomes extremely rare. After 120 days, the logs are almost never read, so moving them to Deep Archive is an appropriate cost-saving step.
- C
Transition the objects to S3 One Zone-IA after 30 days.
Why wrong: One Zone-IA is cheaper than Standard-IA, but it stores data in a single Availability Zone. For log retention data, that is usually a weaker durability choice than needed unless the business explicitly accepts the reduced resilience.
- D
Keep the objects in S3 Standard for the full 400 days.
Why wrong: Keeping all logs in S3 Standard is simple, but it is not cost-optimized for older data that is rarely accessed. The scenario specifically gives a clear decline in access frequency, which is ideal for lifecycle transitions.
- E
Use only S3 Intelligent-Tiering and never add archival transitions.
Why wrong: Intelligent-Tiering can help with unknown or changing access patterns, but this workload has a predictable hot-to-cold progression. Adding explicit lifecycle transitions to colder classes is typically cheaper for long retention with rare later access.
SAA-C03 Design Cost-Optimized Architectures Practice Question
This SAA-C03 practice question tests your understanding of design cost-optimized architectures. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 keeps application logs in Amazon S3 for 400 days. The logs are read heavily for the first 30 days, occasionally for the next 90 days, and almost never after that. The team wants to lower storage cost without affecting retention requirements. Which two lifecycle transitions should it configure? Select two.
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.
Clue:
"never"Why it matters: Absolute qualifier. True only if the statement has zero exceptions — be cautious of options that seem obvious but break down in edge cases.
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 the objects to S3 Standard-IA after 30 days.
Option A is correct because after the first 30 days of heavy read access, transitioning to S3 Standard-IA reduces storage costs while still providing low-latency retrieval for the occasional reads that occur over the next 90 days. S3 Standard-IA is designed for data accessed infrequently but requires rapid access, matching the usage pattern described.
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
The trap here is that candidates often confuse 'occasional access' with 'rare access' and incorrectly choose Glacier Deep Archive too early, or they overlook that S3 Intelligent-Tiering does not include archival tiers, leading to higher costs for long-term retention.

Detailed technical explanation
How to think about this question
S3 lifecycle policies allow you to define transitions based on object age, and the minimum transition age for S3 Standard-IA is 30 days. For data that is almost never accessed after 120 days, S3 Glacier Deep Archive is the lowest-cost storage class, with a retrieval cost that is acceptable for rare access, but it requires a retrieval time of 12–48 hours. The key is to match the access pattern to the appropriate storage class: Standard for frequent access, Standard-IA for occasional access, and Glacier Deep Archive for archival data.
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.
