- A
Use an IAM user in Account B and hard-code the narrower S3 path in its access key policy.
Why wrong: This reintroduces long-term credentials and defeats the purpose of using STS assumed-role access. It also creates a separate identity instead of reusing the central deployment role.
- B
Add a bucket ACL that grants write access only to the TeamA pipeline session name.
Why wrong: S3 ACLs cannot evaluate STS session names or enforce per-session restrictions. They are also a poor fit for least-privilege automation because they are coarse and difficult to manage safely at scale.
- C
Attach a permissions boundary to the central role so every pipeline session inherits the narrower prefix automatically.
Why wrong: A permissions boundary limits the maximum permissions of an IAM principal, but it does not let different callers apply different temporary restrictions when they assume the same role. The boundary would apply to the role itself, not dynamically to one TeamA session versus other pipeline sessions.
- D
Pass an STS session policy when TeamA assumes the role to further restrict the temporary credentials to the teamA/prod prefix.
An STS session policy is specifically designed to reduce the permissions of temporary credentials for a single assume-role session. The reusable base role can remain broad enough for multiple pipelines, while TeamA can pass a session policy that limits effective permissions to the teamA/prod prefix. This preserves the shared role model and achieves least privilege without creating a separate IAM role.
SAA-C03 Design Secure Architectures Practice Question
This SAA-C03 practice question tests your understanding of design secure architectures. 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.
Based on the exhibit, a central deployment role in Account A is assumed by several CI/CD pipelines from Account B. The role must remain reusable, but the team wants the TeamA pipeline to upload artifacts only to s3://artifact-bucket/teamA/prod/ without creating a separate IAM role. What is the best approach?

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
Pass an STS session policy when TeamA assumes the role to further restrict the temporary credentials to the teamA/prod prefix.
Option D is correct because when the TeamA pipeline assumes the central IAM role in Account A, it can pass an STS session policy that further restricts the temporary credentials to only allow actions on the s3://artifact-bucket/teamA/prod/ prefix. This approach keeps the role reusable for other pipelines while enforcing a narrower permission scope at the session level, without requiring a separate IAM role.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Use an IAM user in Account B and hard-code the narrower S3 path in its access key policy.
Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think a permissions boundary (Option C) can dynamically restrict individual sessions, but permissions boundaries set a hard limit on the role's overall permissions and cannot be applied per-session like an STS session policy can.
Detailed technical explanation
How to think about this question
When an IAM role is assumed via STS AssumeRole, the resulting temporary credentials are governed by the intersection of the role's trust policy, the role's permissions policy, and any session policy passed in the request. The session policy acts as a further filter, allowing you to scope permissions down to a specific resource path (e.g., s3://artifact-bucket/teamA/prod/*) without modifying the role itself. This is commonly used in CI/CD scenarios where a central deployment role must be shared across teams but each team needs isolated access to specific S3 prefixes.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
