The answer is the AWS Schema Conversion Tool (SCT) and AWS Database Migration Service (DMS). SCT is the primary service for assessing database compatibility for AWS migration because it analyzes the source MySQL schema and identifies any conversion issues or unsupported features when targeting Amazon RDS for MySQL, providing a detailed action plan for remediation. DMS complements this by performing a data-type assessment and validation during its task creation, flagging potential conversion errors before the actual migration begins. On the AWS Certified Database Specialty DBS-C01 exam, this pairing tests your understanding of the pre-migration assessment phase, where SCT handles schema-level compatibility and DMS handles data-level compatibility—a common trap is confusing DMS solely as a data transfer tool. Remember the memory tip: SCT for the *structure*, DMS for the *data*.
DBS-C01 Deployment and Migration Practice Question
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 is migrating an on-premises MySQL database to Amazon RDS for MySQL. Which TWO AWS services can assist in assessing the source database for compatibility issues?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Database Migration Service (DMS)
AWS SCT can assess source schema for compatibility with RDS. AWS DMS can assess data types and conversion issues as part of its task validation. Trusted Advisor is for cost optimization, not database compatibility. CloudWatch is for monitoring. Inspector is for security assessment.
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 Database Migration Service (DMS)
Why this is correct
DMS can perform a validation to check data type compatibility.
Related concept
Static NAT maps one inside address to one outside address.
✗
AWS Trusted Advisor
Why it's wrong here
Trusted Advisor does not assess database compatibility.
✗
Amazon CloudWatch
Why it's wrong here
CloudWatch monitors performance, not compatibility.
✓
AWS Schema Conversion Tool (SCT)
Why this is correct
SCT analyzes source schema and identifies compatibility issues.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon Inspector
Why it's wrong here
Inspector is for security vulnerability assessment.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
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.
Deployment and Migration — This question tests Deployment and Migration — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: AWS Database Migration Service (DMS) — AWS SCT can assess source schema for compatibility with RDS. AWS DMS can assess data types and conversion issues as part of its task validation. Trusted Advisor is for cost optimization, not database compatibility. CloudWatch is for monitoring. Inspector is for security assessment.
What should I do if I get this DBS-C01 question wrong?
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.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
