The answer is to verify that network connectivity and firewall rules allow HSR traffic, that the source and target systems use the same hostname or proper name resolution, and that both systems run the same SAP HANA major version. These three items are critical because SAP HANA System Replication relies on consistent hostname resolution to establish a secure connection, compatible software versions to ensure data consistency, and open ports—specifically port 3<instance>01 for HSR traffic—to synchronize logs and data between the primary and secondary databases. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of common misconfigurations during HANA migration, often appearing as a trap where candidates mistakenly focus on storage types or licenses, which are irrelevant to replication sync. A useful memory tip is “HNR”: Hostname, Net (firewall), and Release version—always check these three before troubleshooting deeper issues.
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. 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. 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 is migrating an SAP HANA database from on-premises to AWS using SAP HANA System Replication (HSR). They have set up the replication but the target database is not in sync. Which THREE configuration items should the migration team verify? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The hostname resolution between source and target
Option A is correct because HSR requires the same hostname or proper name resolution. Option C is correct because the HANA version must be compatible (same major version). Option E is correct because the system replication port must be open. Option B is incorrect because the source and target can have different storage types. Option D is incorrect because the HANA license is not required for replication (it's per system).
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The hostname resolution between source and target
Why this is correct
HSR uses hostnames; DNS or /etc/hosts must be correct.
Related concept
Static NAT maps one inside address to one outside address.
✓
The HANA version and build number are compatible
Why this is correct
Version mismatch can prevent replication.
Related concept
Static NAT maps one inside address to one outside address.
✗
The SAP HANA license is activated on the target
Why it's wrong here
License is not required for replication setup.
✓
The network connectivity and firewall rules allow HSR traffic
Why this is correct
Port 30101 (or custom) must be open between systems.
Related concept
Static NAT maps one inside address to one outside address.
✗
The storage type (SSD vs HDD) is identical
Why it's wrong here
Storage type does not affect HSR replication.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
Migration — This question tests Migration — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: The hostname resolution between source and target — Option A is correct because HSR requires the same hostname or proper name resolution. Option C is correct because the HANA version must be compatible (same major version). Option E is correct because the system replication port must be open. Option B is incorrect because the source and target can have different storage types. Option D is incorrect because the HANA license is not required for replication (it's per system).

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is migrating an SAP HANA database to AWS. They have set up HANA System Replication (HSR) between the on-premises primary and an AWS secondary. The initial data synchronization is complete, but during the final cutover, the replication breaks due to network latency. What should the company do to complete the migration successfully?
medium
✓ A.Perform a manual takeover to promote the AWS secondary to primary.
B.Set up a new HSR connection with a different port.
C.Increase the HSR timeout settings on the primary.
D.Restart the initial synchronization from scratch.
Why A: The correct action is to perform a manual failover using HSR takeover, which will promote the AWS secondary to primary and allow the system to continue. Increasing timeout may not resolve underlying latency. Restarting replication will take time. Setting up a new replication is unnecessary.
Variation 2. A company is migrating an SAP HANA database using SAP HANA System Replication (HSR) to AWS. The target EC2 instance is in a different AWS Region than the source. The network latency between regions is high. What should the migration team configure to ensure successful replication?
medium
A.Set up a VPN connection to the target region
B.Disable HSR preload on the target
✓ C.Use AWS Global Accelerator to route traffic over the AWS global network
D.Increase the HSR timeout values significantly
Why C: Option A is incorrect because increasing timeout may hide issues but not solve latency. Option B is incorrect because using a VPN over internet adds overhead and latency. Option C is correct because using AWS Global Accelerator optimizes the network path and reduces latency impact. Option D is incorrect because disabling preload may reduce performance but not address latency.
