- A
Configure the volumes as a RAID 0 array and take a snapshot of the array.
Why wrong: RAID 0 does not provide built-in snapshot consistency; snapshots of individual volumes are still independent.
- B
Take snapshots of each volume individually while the instance is running.
Why wrong: Individual snapshots are not crash-consistent across volumes; writes may happen between snapshots.
- C
Stop the EC2 instance, take snapshots of all volumes, then start the instance.
Why wrong: Stopping the instance ensures consistency but causes downtime, which may not be acceptable for production.
- D
Use AWS Backup with application-consistent snapshots using pre- and post-scripts.
AWS Backup can orchestrate snapshots across multiple volumes and run scripts to freeze the filesystem and database, ensuring consistency.
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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.
An SAP administrator needs to ensure that Amazon EBS snapshots of SAP HANA data volumes are crash-consistent. The HANA database is on a single EC2 instance with multiple EBS volumes. What is the correct 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
Use AWS Backup with application-consistent snapshots using pre- and post-scripts.
Option D is correct because AWS Backup with application-consistent snapshots uses pre- and post-scripts to quiesce the SAP HANA database, ensuring that all EBS volumes are captured in a crash-consistent state. This approach coordinates the snapshot process across multiple volumes without stopping the EC2 instance, maintaining data integrity for SAP HANA's data volumes.
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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume stopping the instance (Option C) is the only way to ensure crash consistency, overlooking AWS Backup's ability to achieve the same result without downtime using application-consistent snapshots.
Detailed technical explanation
How to think about this question
Crash consistency across multiple EBS volumes requires that all snapshots represent the same point in time, which is achieved by freezing I/O operations via application-aware scripts (e.g., using SAP HANA's hdbsql to enter backup mode). AWS Backup orchestrates this by executing pre-scripts to quiesce the database and post-scripts to resume operations, leveraging the EBS Multi-Volume Snapshot API that snapshots volumes atomically. In real-world scenarios, failing to coordinate snapshots can lead to database corruption during recovery, especially with SAP HANA's log and data volumes.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
