Migration and Transfer

Correct Answer: IBM Db2

IBM Db2 is not a supported target database engine for AWS Database Migration Service (AWS DMS). AWS DMS supports various popular databases as target engines, including Amazon Aurora MySQL-Compatible Edition, Microsoft SQL Server, and Oracle Database. However, IBM Db2 is not mentioned in the list of supported target engines for AWS DMS.

Correct Answer: Migrating databases from on-premises to AWS cloud with minimal downtime

The best answer is 'Migrating databases from on-premises to AWS cloud with minimal downtime'. This is a key use case for AWS Database Migration Service (AWS DMS) because it allows for the migration of databases from on-premises environments to the AWS cloud while minimizing downtime. AWS DMS supports both homogeneous migrations (such as Oracle to Oracle) and heterogeneous migrations (such as Oracle to Amazon Aurora). It can continuously replicate data with low latency, allowing the source database to remain fully operational during the migration process. The other options, while valid AWS use cases, are not the primary focus or key use case of AWS DMS specifically.

Correct Answer: Minimizes downtime during migration with continuous data replication

AWS Application Migration Service (MGN) is designed to simplify and expedite the migration of applications to the cloud with minimal downtime. The key benefit mentioned in the correct answer is that MGN enables continuous data replication, which allows the source servers to remain fully operational during the migration process. This minimizes downtime and disruption to the business. The other options, while potentially beneficial in certain scenarios, do not represent the core value proposition of MGN. Code conversion and optimization, containerization and deployment, and built-in monitoring and auto-scaling are not the primary focuses of this specific service.
