- 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.
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.
The correct approach is to use SAP HANA System Replication (HSR) with a Database Migration Option (DMO) migration. This allows continuous data replication from the source Oracle database to the target SAP HANA database while the source system remains operational, minimizing downtime. The final cutover is performed quickly. Option B (AWS DMS) is not suitable because AWS DMS does not support SAP HANA as a target. Option C (SAP LaMa) is a landscape management tool that can automate some migration steps but does not in itself provide near-zero downtime replication; it would typically be used with other methods. Option D (classic DMO with SUM in a single step) requires stopping the source system, resulting in extended downtime.
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.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
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.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
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.
