This DBS-C01 practice question tests your understanding of deployment and 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.
Which TWO of the following are required when migrating an on-premises Oracle database to Amazon RDS for Oracle using AWS DMS with change data capture (CDC)? (Select TWO.)
Use AWS SCT to assess schema compatibility.
Required for schema conversion.
Create a full backup of the source database.
Why wrong: Not required; DMS uses logical replication.
Enable supplemental logging on the source Oracle database.
Needed for CDC.
Set up Oracle Data Guard for replication.
Why wrong: DMS handles replication.
Manually create target tables in RDS.
Why wrong: DMS can create them.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use AWS SCT to assess schema compatibility.
For Oracle CDC, DMS requires supplemental logging to capture changes, and an SCT assessment is needed for schema compatibility. Full backup is not required, and native replication is not used. DMS creates target tables automatically.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use AWS SCT to assess schema compatibility.
Why this is correct
Required for schema conversion.
Related concept
Static NAT maps one inside address to one outside address.
Create a full backup of the source database.
Why it's wrong here
Not required; DMS uses logical replication.
Enable supplemental logging on the source Oracle database.
Why this is correct
Needed for CDC.
Related concept
Static NAT maps one inside address to one outside address.
Set up Oracle Data Guard for replication.
Why it's wrong here
DMS handles replication.
Manually create target tables in RDS.
Why it's wrong here
DMS can create them.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. 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 the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DBS-C01 NAT questions on configuration and troubleshooting.
