Quick Answer
The answer is a source endpoint for the on-premises Oracle database, a target endpoint for the Amazon RDS for Oracle instance, and a replication instance. These three components form the core of any AWS DMS task because the replication instance provides the compute and memory resources to connect the source and target endpoints, apply transformations, and capture ongoing changes from the Oracle source to the RDS target. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that ongoing replication—also known as change data capture (CDC)—requires only the infrastructure to move and apply logs, not optional monitoring or notification services like CloudWatch or SNS. A common trap is confusing necessary components with helpful but non-essential add-ons; remember that DMS can function without CloudWatch alarms or SNS topics. Memory tip: think of the three legs of a stool—source, target, and the replication instance that sits between them—and you will never add unnecessary services to your DMS configuration.
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.
An organization is migrating an SAP HANA database to AWS. They plan to use AWS DMS for ongoing replication from an on-premises Oracle database to an Amazon RDS for Oracle instance. Which THREE configurations are necessary for DMS to perform ongoing replication? (Choose THREE.)
An Amazon SNS topic for replication alerts
Why wrong: Optional, not necessary.
A target endpoint for the Amazon RDS for Oracle instance
Required to connect to target.
An Amazon CloudWatch dashboard to monitor replication
Why wrong: Optional, not necessary.
A replication instance in AWS
The compute resource for DMS tasks.
A source endpoint for the on-premises Oracle database
Required to connect to source.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A target endpoint for the Amazon RDS for Oracle instance
DMS needs a source endpoint (Oracle), a target endpoint (RDS Oracle), and a replication instance. Option D (CloudWatch) is for monitoring, not required. Option E (SNS) is for notifications.
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.
An Amazon SNS topic for replication alerts
Why it's wrong here
Optional, not necessary.
A target endpoint for the Amazon RDS for Oracle instance
Why this is correct
Required to connect to target.

A source endpoint for the on-premises Oracle database
Why this is correct

Standard ACLs match source addresses.
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 PAS-C01 ACL questions on filtering logic and placement.
