- A
Amazon S3 bucket versioning
Why wrong: Versioning protects S3 objects, not block storage volumes attached to EC2.
- B
Amazon EBS snapshots
EBS snapshots are the native backup mechanism for EBS volumes. They capture point-in-time copies that can later be used to create a new volume, making them a simple and reliable way to restore data after a server or volume loss. Snapshots are incremental, so repeated backups are efficient and suitable for ongoing protection.
- C
AWS Security Hub
Why wrong: Security Hub helps with security findings, not data backup or restore operations.
- D
Amazon CloudFront invalidations
Why wrong: CloudFront invalidations affect cached web content, not EBS data durability or recovery.

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 production application stores critical data on an Amazon EBS volume. The team wants a simple backup method that allows the volume to be restored later if the server is lost. What should they use?
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
✓
Amazon EBS snapshots
Amazon EBS snapshots are the correct choice because they provide a simple, incremental backup method for EBS volumes. Snapshots capture the data on the volume at a specific point in time and are stored in Amazon S3, allowing the volume to be restored to a new EC2 instance if the original server is lost. This directly meets the requirement for a backup that enables restoration after server failure.
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.
- ✗
Amazon S3 bucket versioning
Why it's wrong here
Versioning protects S3 objects, not block storage volumes attached to EC2.
When this WOULD be correct
A question asks for a backup method for files stored in an S3 bucket, where the requirement is to preserve previous versions of objects to recover from accidental deletions or overwrites. In that scenario, S3 bucket versioning is the correct answer.
- ✓
Amazon EBS snapshots
Why this is correct
EBS snapshots are the native backup mechanism for EBS volumes. They capture point-in-time copies that can later be used to create a new volume, making them a simple and reliable way to restore data after a server or volume loss. Snapshots are incremental, so repeated backups are efficient and suitable for ongoing protection.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
AWS Security Hub
Why it's wrong here
Security Hub helps with security findings, not data backup or restore operations.
When this WOULD be correct
A question asks: 'Which AWS service should be used to centrally view and manage security alerts and compliance status across multiple AWS accounts?' In that context, Security Hub would be the correct answer.
- ✗
Amazon CloudFront invalidations
Why it's wrong here
CloudFront invalidations affect cached web content, not EBS data durability or recovery.
When this WOULD be correct
A company uses CloudFront to distribute a static website and updates the origin content. They need to ensure users see the latest version immediately. CloudFront invalidations would be the correct answer to clear the cache.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SAA-C03 exam frequently reuses these exact scenarios with slightly different constraints.
✓Amazon EBS snapshotsCorrect answer▾
Why this is correct
EBS snapshots are the native backup mechanism for EBS volumes. They capture point-in-time copies that can later be used to create a new volume, making them a simple and reliable way to restore data after a server or volume loss. Snapshots are incremental, so repeated backups are efficient and suitable for ongoing protection.
✗Amazon S3 bucket versioningWrong answer — click to see why▾
Why this is wrong here
Amazon S3 bucket versioning protects objects within S3 from accidental deletion or overwrite, but it does not back up EBS volumes. EBS volumes are block-level storage attached to EC2 instances, and S3 versioning cannot capture or restore the volume's state.
★ When this WOULD be the correct answer
A question asks for a backup method for files stored in an S3 bucket, where the requirement is to preserve previous versions of objects to recover from accidental deletions or overwrites. In that scenario, S3 bucket versioning is the correct answer.
Why candidates choose this
Candidates may think S3 versioning is a general-purpose backup feature, or they confuse it with EBS snapshots which are stored in S3, leading them to believe S3 versioning can back up EBS volumes.
✗AWS Security HubWrong answer — click to see why▾
Why this is wrong here
AWS Security Hub is a security posture management service that aggregates and prioritizes security findings from various AWS services; it does not provide backup or restore capabilities for EBS volumes.
★ When this WOULD be the correct answer
A question asks: 'Which AWS service should be used to centrally view and manage security alerts and compliance status across multiple AWS accounts?' In that context, Security Hub would be the correct answer.
Why candidates choose this
Candidates may confuse 'security' with 'backup' or think that Security Hub includes backup features because it is a security-related service, leading them to select it incorrectly.
✗Amazon CloudFront invalidationsWrong answer — click to see why▾
Why this is wrong here
CloudFront invalidations are used to remove cached content from edge locations, not for backing up or restoring EBS volumes.
★ When this WOULD be the correct answer
A company uses CloudFront to distribute a static website and updates the origin content. They need to ensure users see the latest version immediately. CloudFront invalidations would be the correct answer to clear the cache.
Why candidates choose this
Candidates may confuse 'invalidations' with 'backups' or think that clearing cache is a form of data protection, but it serves a completely different purpose.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might confuse EBS snapshots with S3 versioning, thinking that S3 can directly back up EBS volumes, but EBS snapshots are the native, designed service for this purpose.
Detailed technical explanation
How to think about this question
EBS snapshots are stored in Amazon S3, but they are not directly accessible as S3 objects; they are managed through the EBS API. Snapshots are incremental, meaning only the blocks that have changed since the last snapshot are saved, reducing storage costs and backup time. When restoring a volume from a snapshot, the new volume is lazily loaded from S3, so performance may be lower initially until all blocks are accessed and loaded.
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
