20+ practice questions focused on Deployment and Migration — one of the most tested topics on the AWS Certified Database Specialty DBS-C01 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Deployment and Migration PracticeA company is migrating an on-premises Microsoft SQL Server database to Amazon RDS for SQL Server. The database uses SQL Server Agent jobs for ETL processes. After migration, the company needs to continue running these jobs. What is the MOST efficient way to manage these jobs in the AWS cloud?
Explanation: AWS Lambda functions triggered by Amazon CloudWatch Events (now Amazon EventBridge) provide a serverless, fully managed alternative to SQL Server Agent jobs. This approach eliminates the need to manage any compute infrastructure, as Lambda handles the execution of ETL logic directly against the RDS for SQL Server instance. It is the most efficient because it requires no additional servers, reduces operational overhead, and integrates natively with AWS monitoring and scheduling services.
A company is deploying a new Amazon RDS for PostgreSQL database. The database will be used by an application that requires read-after-write consistency and low latency. Which deployment configuration is MOST suitable?
Explanation: Read replicas in RDS for PostgreSQL use asynchronous replication and do not guarantee read-after-write consistency. For an application requiring read-after-write consistency and low latency, the best choice is to deploy as a single-AZ instance with increased instance size. This avoids replication lag entirely, ensuring that reads from the primary instance always reflect the latest writes, while scaling up provides low latency for both reads and writes.
A company is migrating a 2 TB MySQL database to Amazon Aurora MySQL. They need to minimize downtime and ensure data consistency. Which TWO actions should they take? (Choose two.)
Explanation: Both Option C and Option E are correct. Option C: Creating an Amazon Aurora MySQL read replica from an existing Amazon RDS MySQL DB instance uses MySQL native replication. The Aurora replica stays synchronized with minimal performance impact. When the replica lag reaches zero, you can promote the Aurora instance to a standalone primary, resulting in very low downtime and full data consistency. Option E: Enabling binary logging (binlog) on the source RDS MySQL instance and setting up replication to Aurora MySQL (for example, by creating an Aurora read replica or configuring an external replication channel) ensures continuous synchronization. This method also minimizes downtime and maintains data consistency. Both approaches avoid the need for a full export/import and are ideal for large databases like 2 TB. Options A (mysqldump) would require a long maintenance window, Option B (SCT) handles schema conversion only, and Option D (DMS with CDC) is a valid migration tool but is not the preferred approach here because native replication is simpler and more efficient for MySQL-to-Aurora MySQL migrations.
A developer deploys the CloudFormation stack. After testing, they delete the stack. What happens to the RDS instance?
Explanation: By default, when a CloudFormation stack containing an RDS DB instance is deleted, the instance is deleted and a final snapshot is taken automatically (unless the SkipFinalSnapshot property is explicitly set to true). The stem does not mention any custom DeletionPolicy or DeletionProtection, so the default behavior applies. Option B correctly describes this outcome.
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?
Explanation: AWS DMS and AWS Schema Conversion Tool (SCT) are both used to assess source MySQL databases for compatibility when migrating to Amazon RDS for MySQL. AWS DMS provides a premigration assessment that checks for unsupported data types, table storage engines, and other potential blockers. AWS SCT helps identify schema incompatibilities and can automatically convert the database schema to match the target RDS for MySQL environment. Together, they help identify issues before migration begins, reducing the risk of failures.

Start with 10 questions to gauge your current understanding of Deployment and Migration. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Deployment and Migration questions on the DBS-C01 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
