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.
Which TWO of the following are valid methods to migrate an on-premises MySQL database to Amazon RDS for MySQL? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS DMS to migrate from on-premises MySQL to RDS.
AWS DMS (Database Migration Service) is a fully managed service designed to migrate databases to AWS with minimal downtime. It supports homogeneous migrations like MySQL to Amazon RDS for MySQL, handling schema conversion, data replication, and ongoing changes via change data capture (CDC). This makes option B a valid and recommended method for migrating an on-premises MySQL database to RDS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 pg_dump to export the data and import into RDS.
Why it's wrong here
pg_dump is for PostgreSQL.
✓
Use AWS DMS to migrate from on-premises MySQL to RDS.
Why this is correct
DMS supports MySQL as source.

✗
Use SQL Server Integration Services (SSIS) to migrate the data.
Why it's wrong here
SSIS is for SQL Server.
✗
Use Oracle Data Pump to export the data and import into RDS.
Why it's wrong here
Data Pump is for Oracle databases.
✓
Use mysqldump to export the database and import it into RDS.
Why this is correct
mysqldump is a standard MySQL export tool.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse database-specific tools (pg_dump for PostgreSQL, Oracle Data Pump for Oracle, SSIS for SQL Server) with MySQL-compatible tools, leading them to select options that are technically incorrect for migrating a MySQL database to Amazon RDS for MySQL.
Detailed technical explanation
How to think about this question
mysqldump (option E) creates a logical backup of a MySQL database as a set of SQL statements, which can be directly imported into Amazon RDS for MySQL using the MySQL command-line client. AWS DMS (option B) uses a replication instance to connect to the source MySQL database, read the binary log (binlog) for CDC, and apply changes to the target RDS instance, enabling near-zero downtime migrations. For large databases, mysqldump may be slower and require manual handling of foreign key constraints and character set issues, while DMS can handle continuous replication and schema conversion automatically.
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.
TExam Day Tips
→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.
