SAA-C03 Design Resilient Architectures Practice Question
This SAA-C03 practice question tests your understanding of design resilient 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 inventory service exposes a static website from S3 and CloudFront. Users should still receive cached pages if the S3 origin has a short outage. Which feature helps most?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CloudFront caching with appropriate TTLs
CloudFront caches responses from the S3 origin based on configured TTLs (Cache-Control or Expires headers). If the S3 origin experiences a short outage, CloudFront can still serve cached pages to users from its edge locations, maintaining availability. This is the most direct way to ensure users receive content during origin failures.
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.
✓
CloudFront caching with appropriate TTLs
Why this is correct
CloudFront can serve cached content from edge locations when the origin is temporarily unavailable.

✗
AWS Backup Vault Lock
Why it's wrong here
Backup Vault Lock protects backups, not CloudFront delivery.
✗
IAM Access Analyzer
Why it's wrong here
Access Analyzer reviews permissions and does not serve cached content.
✗
S3 Select
Why it's wrong here
S3 Select retrieves subsets of object data and does not increase origin outage tolerance.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse CloudFront's caching with other AWS services like S3 Transfer Acceleration or S3 Cross-Region Replication, which do not provide cached responses during origin outages.
Detailed technical explanation
How to think about this question
CloudFront caching works by storing responses at edge locations based on TTL values set via Cache-Control max-age or s-maxage directives. During an origin outage, CloudFront can serve stale responses if the origin is unreachable, provided the cached object is still within its TTL window or if you configure custom error responses to serve stale content. This behavior is governed by CloudFront's origin failover capabilities and cache invalidation policies.
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.
