- A
Scale up the source HANA instance to a larger instance type to speed up replication.
Why wrong: Instance size does not affect network transfer speed; replication speed is limited by network and storage I/O.
- B
Increase the network bandwidth between the two Availability Zones to 10 Gbps.
Why wrong: Even with high bandwidth, transferring 2 TB of data takes a significant amount of time; initial sync still lengthy.
- C
Use HANA System Replication with initial snapshot by taking a backup of the source, restoring on the target, and then setting up replication.
Initial snapshot reduces sync time by using a backup restore instead of full data transfer over the network.
- D
Use Amazon RDS for SAP HANA instead of self-managed EC2.
Why wrong: RDS does not support SAP HANA; HANA is self-managed on EC2.
Quick Answer
The answer is to use HANA System Replication with an initial snapshot by taking a backup of the source, restoring it on the target, and then setting up replication. This approach is correct because it dramatically reduces the initial synchronization time for a blue/green deployment for SAP HANA major version upgrade; instead of copying the entire 2 TB of memory over the network during the failover window, the bulk data transfer happens offline via the backup and restore, leaving only incremental changes to be replicated via HSR. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of how to optimize HANA System Replication for large-memory instances, where network transfer time is the bottleneck—a common trap is assuming that increasing bandwidth alone solves the issue, but even with high throughput, copying terabytes of data will exceed a 2-hour SLA. Remember the memory tip: “Backup first, replicate second—don’t let the network be your bottleneck.”
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 SAP ERP on AWS using a single Availability Zone. The system includes an SAP HANA database on an EC2 instance with 2 TB of memory. The operations team plans to perform a major version upgrade of the SAP HANA database, which requires approximately 4 hours of downtime. The company's SLA allows a maximum of 2 hours of downtime. The team decides to use a blue/green deployment strategy by creating a new HANA instance in a different Availability Zone and replicating data using HANA System Replication (HSR). After setting up replication, they perform a failover to the new instance. However, the failover takes 3 hours due to the large amount of data that needs to be synchronized. What should the team do to meet the 2-hour downtime requirement?
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 HANA System Replication with initial snapshot by taking a backup of the source, restoring on the target, and then setting up replication.
Option C is correct. Using initial snapshot with HSR reduces the initial sync time significantly because it avoids copying all data over the network. Instead, the snapshot is restored on the target and then replication catches up. Option A is wrong because increasing bandwidth may help but not enough for 2 TB of memory; the initial sync will still take hours. Option B is wrong because multi-AZ for RDS is for RDS databases, not for self-managed HANA on EC2. Option D is wrong because scaling up the source does not help; the issue is data transfer time.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
