- A
Use AWS Snowball Edge to transfer the database files and then use SCT to convert the schema.
Why wrong: Snowball transfers files, but the database must be stopped; SCT would need to be applied after transfer.
- B
Use AWS Schema Conversion Tool (SCT) to convert the schema and AWS Database Migration Service (DMS) to migrate the data.
SCT converts the schema including Oracle-specific features, and DMS migrates the data efficiently.
- C
Use AWS Database Migration Service (DMS) with the Oracle as source and Aurora PostgreSQL as target.
Why wrong: DMS migrates data but does not convert schema; Oracle-specific features would not be translated.
- D
Use AWS Schema Conversion Tool (SCT) to convert the schema and then manually export/import data.
Why wrong: SCT converts schema but does not migrate data; manual export/import is error-prone and not recommended.
DBS-C01 Deployment and Migration Practice Question
This DBS-C01 practice question tests your understanding of deployment and migration. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 a 500 GB Oracle database to Amazon Aurora PostgreSQL. They need to convert the schema and migrate the data. The application uses Oracle-specific features like hierarchical queries and stored procedures. Which combination of services should they use?
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 Schema Conversion Tool (SCT) to convert the schema and AWS Database Migration Service (DMS) to migrate the data.
Option D (SCT for schema conversion, DMS for data migration) is correct because SCT converts Oracle schema including stored procedures and hierarchical queries, and DMS migrates the data. Option A (DMS only) does not convert schema. Option B (SCT only) does not migrate data. Option C (Snowball with SCT) is for large data transfers but not for ongoing replication or schema conversion of complex features.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Snowball Edge to transfer the database files and then use SCT to convert the schema.
Why it's wrong here
Snowball transfers files, but the database must be stopped; SCT would need to be applied after transfer.
- ✓
Use AWS Schema Conversion Tool (SCT) to convert the schema and AWS Database Migration Service (DMS) to migrate the data.
Why this is correct
SCT converts the schema including Oracle-specific features, and DMS migrates the data efficiently.
Related concept
Static NAT maps one inside address to one outside address.
- ✗

Why it's wrong here
DMS migrates data but does not convert schema; Oracle-specific features would not be translated.
- ✗
Use AWS Schema Conversion Tool (SCT) to convert the schema and then manually export/import data.
Why it's wrong here
SCT converts schema but does not migrate data; manual export/import is error-prone and not recommended.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
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. 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
Got this wrong? Here's your next step.
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.
