- A
Use AWS DMS to migrate the database to Amazon RDS for Oracle, but then configure RDS for Oracle RAC.
Why wrong: RDS for Oracle does not support RAC configuration.
- B
Use AWS DataSync to copy the Oracle database files to EBS volumes, then restore on an EC2 instance.
Why wrong: DataSync is not suitable for database replication; this would cause significant downtime and complexity.
- C
Use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.
This reduces licensing costs and simplifies the architecture. DMS supports Oracle as source and target RDS Oracle.
- D
Lift-and-shift the Oracle RAC cluster to EC2 using AWS Application Migration Service.
Why wrong: Oracle RAC is not supported on AWS in a fully supported manner for SAP; also licensing costs remain high.
Quick Answer
The answer is to use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance, and AWS MGN for the application servers. This is the most efficient strategy because AWS does not support Oracle RAC in a fully supported manner for SAP, and moving to a single-instance RDS for Oracle eliminates the costly Oracle RAC licensing while simplifying the architecture. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your understanding of the SAP-certified migration path that prioritizes licensing reduction and operational simplicity over maintaining on-premises high-availability patterns. A common trap is assuming you can keep Oracle RAC on AWS, but the exam expects you to recognize that RAC is unsupported for SAP workloads on AWS, making RDS or a single EC2 instance the correct target. Memory tip: “RAC is a trap—RDS cuts the licensing sap.”
PAS-C01 Migration Practice Question
This PAS-C01 practice question tests your understanding of migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 its SAP ERP system (with Oracle database) to AWS using the SAP-certified approach. The current on-premises environment uses Oracle RAC for high availability. The company wants to reduce licensing costs and simplify the architecture on AWS. Which of the following is the MOST efficient migration strategy?
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 AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.
AWS does not support Oracle RAC in a fully supported manner for SAP. The best practice is to migrate to Amazon RDS for Oracle or use Oracle single instance on EC2. Using AWS DMS with ongoing replication can minimize downtime. Option B is correct because it uses DMS and moves to RDS, which reduces licensing overhead. Option A uses RAC which is not recommended on AWS. Option C uses DMS but then keeps RAC, which is costly and unsupported. Option D uses DataSync which is not for database replication.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS DMS to migrate the database to Amazon RDS for Oracle, but then configure RDS for Oracle RAC.
Why it's wrong here
RDS for Oracle does not support RAC configuration.
- ✗
Use AWS DataSync to copy the Oracle database files to EBS volumes, then restore on an EC2 instance.
Why it's wrong here
DataSync is not suitable for database replication; this would cause significant downtime and complexity.
- ✓
Use AWS DMS to migrate the Oracle database to Amazon RDS for Oracle with a single instance. Use AWS MGN for the application servers.
Why this is correct
This reduces licensing costs and simplifies the architecture. DMS supports Oracle as source and target RDS Oracle.
Related concept
Standard ACLs match source addresses.
- ✗
Lift-and-shift the Oracle RAC cluster to EC2 using AWS Application Migration Service.
Why it's wrong here
Oracle RAC is not supported on AWS in a fully supported manner for SAP; also licensing costs remain high.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
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.
