The answer is the AWS Schema Conversion Tool (AWS SCT). This is the correct choice because AWS SCT is specifically designed to automate the conversion of database schemas and code, including Oracle PL/SQL stored procedures, into the PostgreSQL dialect used by Amazon Aurora. It handles the heavy lifting of translating proprietary Oracle syntax, such as packages and cursors, into PostgreSQL-compatible code, which directly addresses the need to minimize manual changes during migration. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your understanding of the distinct roles of migration tools: AWS DMS moves data, while AWS SCT converts schema and code. A common trap is confusing DMS with SCT, but remember that DMS handles rows, not code. For a quick memory tip, think "SCT for Scripts, DMS for Data."
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. 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 an on-premises Oracle database to Amazon Aurora PostgreSQL. The database has several stored procedures that use Oracle-specific PL/SQL. The team needs to minimize manual code changes. Which AWS service or tool should be used to automate the conversion of the stored procedures?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Schema Conversion Tool (AWS SCT)
Option B is correct because the AWS Schema Conversion Tool (AWS SCT) is designed to convert database schemas, including stored procedures, from one engine to another. Option A is wrong because DMS is for data migration, not schema or code conversion. Option C is wrong because SCT can handle the conversion, and a manual rewrite is not necessary; SCT automates most of it. Option D is wrong because the PostgreSQL compatibility mode in Amazon Aurora does not automatically convert Oracle PL/SQL.
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.
✓
AWS Schema Conversion Tool (AWS SCT)
Why this is correct
AWS SCT automates the conversion of database schemas and code, including PL/SQL, to target database engines.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon Aurora PostgreSQL native compatibility
Why it's wrong here
Aurora PostgreSQL does not natively convert Oracle PL/SQL; manual rewriting would be needed.
✗
AWS Database Migration Service (AWS DMS)
Why it's wrong here
AWS DMS migrates data, not schema or code; it does not convert stored procedures.
✗
Manual rewrite using PostgreSQL PL/pgSQL
Why it's wrong here
Manual rewrite is not minimizing manual changes; AWS SCT can automate a significant portion.
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.

Are there clue words in this question I should notice?
Yes — watch for: "minimum / minimize". Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
