Quick Answer
Amazon Redshift is the correct choice because it is the only AWS service purpose-built for data warehousing that supports a direct migration from Oracle with minimal effort using the AWS Schema Conversion Tool (SCT). SCT automates the conversion of Oracle schemas, stored procedures, and ETL logic into Redshift-compatible code, drastically reducing manual rework while preserving the analytical workload’s core structure. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to distinguish between OLTP databases (like RDS and Aurora) and OLAP data warehouses, with Redshift being the only valid target for a large Oracle RAC cluster. A common trap is choosing Aurora or RDS because they support Oracle compatibility, but they lack the columnar storage and massive parallel processing needed for data warehouse workloads. Memory tip: think “SCT + Redshift = shift your warehouse with minimal lift.”
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. 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 planning to migrate its on-premises data warehouse to AWS. The data warehouse runs on a large Oracle RAC cluster with complex stored procedures and ETL jobs. The company wants to minimize migration effort while gaining cloud benefits. Which AWS service should be used as the target?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Amazon DynamoDB
Why wrong: DynamoDB is a NoSQL database, not suitable for data warehouse workloads.
Amazon RDS for Oracle
Why wrong: RDS is not designed for data warehouse workloads.
Amazon Redshift
Redshift is AWS's data warehouse service, suitable for migrating from Oracle.
Amazon Aurora PostgreSQL
Why wrong: Aurora is a relational database, not a data warehouse.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon Redshift
Option C is correct because Amazon Redshift is the AWS data warehouse that can migrate from Oracle with minimal changes using SCT. Option A is wrong because RDS is not a data warehouse. Option B is wrong because Aurora is a relational database, not a data warehouse. Option D is wrong because DynamoDB is a NoSQL database.
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
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon DynamoDB
Why it's wrong here
DynamoDB is a NoSQL database, not suitable for data warehouse workloads.
Amazon RDS for Oracle
Why it's wrong here
RDS is not designed for data warehouse workloads.
Amazon Redshift
Why this is correct
Redshift is AWS's data warehouse service, suitable for migrating from Oracle.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
Amazon Aurora PostgreSQL
Why it's wrong here
Aurora is a relational database, not a data warehouse.
Common exam traps
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
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.
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
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
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 SAP-C02 ACL questions on filtering logic and placement.
