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. A key principle to apply: s3 Cross-Region Replication (CRR) asynchronously copies objects between S3 buckets in different AWS Regions.. 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 trading dashboard stores uploaded documents in S3. The business requires a copy in another AWS Region for disaster recovery. What should be configured? The architecture review board prefers a managed AWS-native control.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
S3 Cross-Region Replication with versioning enabled
S3 Cross-Region Replication (CRR) is the correct AWS-native managed solution for automatically replicating objects from a source S3 bucket in one region to a destination bucket in another region, meeting the disaster recovery requirement. Versioning must be enabled on both source and destination buckets for CRR to function, as replication relies on version IDs to track and copy objects. This provides asynchronous, automatic replication without custom scripting or third-party tools.
Key principle: S3 Cross-Region Replication (CRR) asynchronously copies objects between S3 buckets in different AWS Regions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
An EBS snapshot schedule
Why it's wrong here
EBS snapshots do not apply to S3 objects.
✓
S3 Cross-Region Replication with versioning enabled
Why this is correct
CRR asynchronously replicates objects to a bucket in another Region and requires versioning.
Related concept
S3 Cross-Region Replication (CRR) asynchronously copies objects between S3 buckets in different AWS Regions.
✗
S3 lifecycle transition to Glacier Flexible Retrieval
Why it's wrong here
Lifecycle transition changes storage class, not Region.
✗
A CloudFront distribution
Why it's wrong here
CloudFront caches content but is not a durable DR copy.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse S3 lifecycle policies (which only manage storage tiers within a region) with cross-region replication, or incorrectly assume CloudFront's global edge caching provides durable DR storage in another region.
Detailed technical explanation
How to think about this question
S3 CRR uses the source bucket's replication configuration, which includes a destination bucket ARN, an IAM role for cross-account access (if needed), and optional filters (e.g., prefix or tags). Replication is asynchronous and typically completes within 15 minutes, but can be slower for large objects; S3 RTC (Replication Time Control) can guarantee replication within 15 minutes for a fee. A subtle behavior: if you enable CRR on an existing bucket, only new objects are replicated by default—existing objects require a batch operation or manual copy.
KKey Concepts to Remember
S3 Cross-Region Replication (CRR) asynchronously copies objects between S3 buckets in different AWS Regions.
CRR requires S3 Versioning to be enabled on both the source and destination buckets.
CRR is a managed, AWS-native service for disaster recovery and compliance.
CRR replicates new objects, object updates, and delete markers.
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
S3 Cross-Region Replication (CRR) asynchronously copies objects between S3 buckets in different AWS Regions.
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.
