The correct answer combines AWS Database Migration Service with ongoing change data capture, AWS Schema Conversion Tool for schema optimization, and an AWS Snowball Edge device for the initial data load. This approach solves the core challenge of migrating a large MySQL database to Amazon Aurora over a slow network because the Snowball Edge bypasses the 500 Mbps bottleneck entirely, physically transferring the 5 TB baseline while DMS with CDC handles only the incremental changes during the cutover, drastically reducing online transfer time. On the AWS Certified Database Specialty DBS-C01 exam, this scenario tests your understanding of hybrid migration strategies where network bandwidth is the constraint—a common trap is assuming a VPN or read replica alone can perform the migration, but neither moves the initial data load efficiently. Remember the memory tip: “Snowball for the heavy lift, DMS for the drift.”
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 a 5 TB MySQL database to Amazon Aurora MySQL. The migration must have minimal downtime and support ongoing replication. The source database is in a corporate data center with a 500 Mbps internet connection. Which THREE steps should the database specialist take?
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 (AWS SCT) to convert the schema.
Options A, C, and E are correct. Option A: AWS DMS with CDC allows ongoing replication with minimal downtime. Option C: Using AWS SCT helps convert the schema if needed. Option E: Using an AWS Snowball Edge device for initial load reduces the time for large data transfer over slow internet. Option B is wrong because a VPN alone does not migrate data. Option D is wrong because a read replica is not a migration tool; it is a feature of Aurora.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Establish a VPN connection to AWS and use mysqldump.
Why it's wrong here
mysqldump over slow internet would take too long.
✓
Use AWS Schema Conversion Tool (AWS SCT) to convert the schema.
Why this is correct
SCT helps with schema conversion if needed.

✗
Create an Aurora read replica from the source database.
Why it's wrong here
Read replicas are not used for migration.
✓
Set up AWS Database Migration Service (AWS DMS) with change data capture (CDC).
Why this is correct
DMS with CDC enables minimal downtime migration.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
