Quick Answer
The answer is the AWS Schema Conversion Tool (AWS SCT). This is the correct choice because AWS SCT is specifically designed to convert database schema and complex code objects, such as Oracle stored procedures, into Amazon Redshift compatible code, handling syntax and logic differences between the two engines. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between migration tools: AWS DMS handles data movement, not schema conversion, while AWS Glue and the COPY command serve ETL and data loading purposes respectively. A common trap is confusing AWS DMS with schema conversion, but remember that DMS moves the data, while SCT transforms the code. For a quick memory tip, think "SCT for the script, DMS for the data" to keep their roles straight during the exam.
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.
A company wants to migrate its Oracle data warehouse to Amazon Redshift. The source database is 10 TB and has many complex stored procedures. Which AWS service should be used primarily for converting the stored procedures to Amazon Redshift compatible code?
AWS Glue
Why wrong: Glue is an ETL service, not specialized for schema conversion.
AWS Database Migration Service (AWS DMS)
Why wrong: DMS migrates data but does not convert stored procedures.
Amazon Redshift COPY command
Why wrong: COPY loads data from S3 into Redshift, not for schema conversion.
AWS Schema Conversion Tool (AWS SCT)
SCT converts schema and code objects like stored procedures to target engine syntax.

Correct answer & explanation
AWS Schema Conversion Tool (AWS SCT)
Option A is correct because AWS Schema Conversion Tool (AWS SCT) is designed to convert database schema and code objects like stored procedures from one engine to another. Option B is wrong because AWS DMS migrates data, not schema/code. Option C is wrong because Amazon Redshift's COPY command loads data from S3. Option D is wrong because AWS Glue is an ETL service, not specialized for schema conversion.
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.
AWS Glue
Why it's wrong here
Glue is an ETL service, not specialized for schema conversion.
AWS Database Migration Service (AWS DMS)
Why it's wrong here
DMS migrates data but does not convert stored procedures.
Amazon Redshift COPY command
Why it's wrong here
COPY loads data from S3 into Redshift, not for schema conversion.
AWS Schema Conversion Tool (AWS SCT)
Why this is correct
SCT converts schema and code objects like stored procedures to target engine syntax.
Related concept
Static NAT maps one inside address to one outside address.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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.
