- A
Deploy a second EC2 instance in a different Availability Zone and configure SAP HANA system replication.
Deploying a second EC2 instance in a different AZ with SAP HANA system replication ensures a synchronous standby that can take over within minutes, reducing RTO to under 15 minutes.
- B
Use AWS Backup to create more frequent snapshots.
Why wrong: AWS Backup snapshots require restoring the volume and replaying logs, which can take 45 minutes or more; more frequent snapshots do not reduce the time for log replay.
- C
Increase the provisioned IOPS of the EBS volume.
Why wrong: Increasing provisioned IOPS improves I/O performance but does not reduce recovery time; recovery is dominated by log replay and volume attachment.
- D
Move the database to Amazon S3 for faster access.
Why wrong: Amazon S3 is not a block storage solution for databases; it is object storage and cannot be used as a primary database storage for SAP HANA.
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. 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 company runs its SAP HANA database on an EC2 instance in a single Availability Zone. The system is critical and requires high availability. The current setup uses an EBS volume for data storage. During a recent failure simulation, the database took 45 minutes to recover because the EBS volume had to be reattached and the database had to replay logs. The operations team wants to reduce recovery time to less than 15 minutes. Which solution should they implement?
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
Deploy a second EC2 instance in a different Availability Zone and configure SAP HANA system replication.
Option A is correct because deploying a second EC2 instance in a different Availability Zone with SAP HANA system replication (synchronous replication) provides a standby database that can be promoted quickly, reducing recovery time to minutes. Option B is incorrect because more frequent snapshots still require restoring and log replay, which takes longer. Option C is incorrect because increasing provisioned IOPS improves performance but does not affect recovery time during failure. Option D is incorrect because Amazon S3 is an object storage service not suitable for low-latency database operations like SAP HANA.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 |
