- A
Use SAP HANA System Replication (HSR) with DMO to replicate data while the source is running, then perform a final cutover.
HSR with DMO allows minimal downtime by replicating changes during the migration.
- B
Use AWS Database Migration Service (DMS) to continuously replicate from Oracle to HANA.
Why wrong: DMS does not support SAP HANA as a target database.
- C
Use SAP Landscape Management (LaMa) to automate the migration with minimal downtime.
Why wrong: LaMa can automate but does not inherently provide near-zero downtime migration for database migration.
- D
Perform a classic migration using SAP Software Update Manager (SUM) with database migration option (DMO) in a single step, stopping the source system.
Why wrong: This causes significant downtime as the source system must be stopped.
Quick Answer
The correct choice is to use SAP HANA System Replication (HSR) with DMO, as this combination enables near-zero downtime by continuously replicating data from the source Oracle database to the target HANA system while the source remains fully operational, with only a brief final cutover to switch users. This approach leverages HSR’s log-based replication to keep the target synchronized and DMO’s ability to handle the heterogeneous migration process, making it ideal for migrating Oracle to SAP HANA on AWS with minimal downtime. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of high-availability migration strategies versus cold migration traps—many candidates mistakenly choose AWS DMS, but it does not support HANA as a target, or SAP LaMa, which orchestrates but doesn’t provide near-zero downtime replication. Remember the memory tip: “HSR + DMO = HANA Sync, Zero Downtime.”
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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.
Your company is running SAP Business Suite on Oracle on AWS. The database is hosted on an EC2 instance with EBS volumes configured as RAID 0 for performance. You are planning to migrate to SAP HANA on AWS. The new HANA database will be hosted on a single EC2 instance with EBS io2 volumes. You need to ensure minimal downtime during the migration. Which approach should you take?
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 SAP HANA System Replication (HSR) with DMO to replicate data while the source is running, then perform a final cutover.
Option C is correct because using SAP HANA System Replication with a DMO migration allows near-zero downtime by replicating data while the source system is running. Option A (cold migration) causes extended downtime. Option B (AWS DMS) is not suitable for migrating from Oracle to HANA as it does not support HANA as a target. Option D (SAP LaMa) can assist but does not directly provide near-zero downtime migration.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

- ✓
Use SAP HANA System Replication (HSR) with DMO to replicate data while the source is running, then perform a final cutover.
Why this is correct
HSR with DMO allows minimal downtime by replicating changes during the migration.
Related concept
Standard ACLs match source addresses.
- ✗
Use AWS Database Migration Service (DMS) to continuously replicate from Oracle to HANA.
Why it's wrong here
DMS does not support SAP HANA as a target database.
- ✗
Use SAP Landscape Management (LaMa) to automate the migration with minimal downtime.
Why it's wrong here
LaMa can automate but does not inherently provide near-zero downtime migration for database migration.
- ✗
Perform a classic migration using SAP Software Update Manager (SUM) with database migration option (DMO) in a single step, stopping the source system.
Why it's wrong here
This causes significant downtime as the source system must be stopped.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PAS-C01 ACL questions on filtering logic and placement.

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 runs its SAP Business Suite on AWS with an Oracle database on an EC2 instance. The database is stored on multiple EBS volumes configured as a RAID 0 array. The company wants to migrate the database to SAP HANA on a new EC2 instance. The SAP HANA instance will use EBS volumes for data and log storage. The current Oracle database size is 500 GB. The company needs to minimize downtime during the migration. Which migration strategy should they use?
hard- A.Use AWS Application Migration Service to migrate the entire EC2 instance.
- ✓ B.Use SAP HANA System Replication to replicate data from the source Oracle database to the target HANA database.
- C.Export the Oracle database to a flat file and import into SAP HANA.
- D.Use AWS Database Migration Service (DMS) to migrate from Oracle to SAP HANA.
Why B: Option A is correct: Using SAP HANA System Replication with initial load from backup is the standard low-downtime method. Option B is wrong because DMS does not support SAP HANA as a target for homogeneous migration. Option C is wrong because AWS Application Migration Service is for server migration, not database. Option D is wrong because a manual export/import requires significant downtime.
