This DBS-C01 practice question tests your understanding of deployment and migration. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 has a 50 GB MariaDB database on an on-premises server. They want to migrate to Amazon RDS for MariaDB. They have a 100 Mbps network connection. The migration window is 2 hours. The database can be offline for up to 30 minutes. Which migration approach is most appropriate?
Use AWS DMS with ongoing replication.
Why wrong: Overkill for a 50 GB database with 30 min downtime allowed.
Use AWS Snowball to transfer the database files.
Why wrong: Unnecessary for small database.
Create a MariaDB dump, transfer to an EC2 instance in the same region, then import to RDS.
Simple and within window; dump/import time ~20 minutes.
Use AWS SCT to convert schema and then use DMS.
Why wrong: SCT not needed for MariaDB to MariaDB.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a MariaDB dump, transfer to an EC2 instance in the same region, then import to RDS.
Option A is correct: creating a dump and importing is straightforward and can be done within the window. Option B is wrong because DMS may require more setup. Option C is wrong because Snowball is overkill. Option D is wrong because SCT is for schema conversion, not needed here.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Why it's wrong here
Overkill for a 50 GB database with 30 min downtime allowed.
Use AWS Snowball to transfer the database files.
Why it's wrong here
Unnecessary for small database.
Create a MariaDB dump, transfer to an EC2 instance in the same region, then import to RDS.
Why this is correct
Simple and within window; dump/import time ~20 minutes.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
