Accelerate Workload Migration and Modernization: free practice questions

5 sample questions from our 15-question bank for this domain — answers and explanations included. These are the same scenario-based style as the real AWS exam.

1. As part of modernization, a team wants to replace a batch-oriented monolith component with event-driven, serverless functions triggered by new data arriving in S3. Which service should the architect recommend?

  • A. AWS Lambda triggered by S3 event notifications✓ Correct
  • B. A cron job on a persistent EC2 instance polling S3
  • C. Amazon Redshift Spectrum
  • D. AWS Direct Connect
Explanation

Lambda invoked by S3 event notifications gives event-driven, serverless processing that scales automatically and bills per use — a common modernization pattern. A polling EC2 cron job (B) is server-based and less responsive, Redshift Spectrum (C) queries S3 data for analytics, and Direct Connect (D) is connectivity.

2. A migration program spanning hundreds of servers across several tools needs a single place to discover, plan, track, and visualize migration progress. Which service should the architect recommend?

  • A. AWS Migration Hub✓ Correct
  • B. AWS Trusted Advisor
  • C. Amazon QuickSight only
  • D. AWS Secrets Manager
Explanation

AWS Migration Hub provides a central location to discover servers, plan migrations, and track progress across multiple AWS and partner migration tools. Trusted Advisor (B) gives best-practice checks, QuickSight (C) is BI, and Secrets Manager (D) stores secrets.

3. A team migrating a large on-premises database to Amazon RDS wants continuous replication with minimal downtime, and can convert the schema if moving engines. Which AWS tools should the architect recommend?

  • A. AWS Database Migration Service (DMS), with the AWS Schema Conversion Tool (SCT) for heterogeneous migrations✓ Correct
  • B. Manually exporting and importing a nightly dump
  • C. AWS Snowball only
  • D. Amazon CloudFront
Explanation

AWS DMS replicates data with minimal downtime, and SCT converts schema/code for heterogeneous engine changes (e.g., Oracle → PostgreSQL). A nightly dump (B) requires extended downtime, Snowball (C) is for bulk offline data transfer, and CloudFront (D) is a CDN.

4. During migration planning, an application is found to be unused and can be decommissioned rather than migrated. Which 'R' applies?

  • A. Retire✓ Correct
  • B. Rehost
  • C. Replatform
  • D. Repurchase
Explanation

Retire means decommissioning an application that's no longer needed, saving migration effort and cost. Rehost (B) moves it as-is, replatform (C) makes minor optimizations during the move, and repurchase (D) switches to a different product (e.g., SaaS).

5. A company wants ongoing, incremental synchronization of on-premises file data to Amazon S3/EFS over the network as part of a phased migration. Which service should the architect recommend?

  • A. AWS DataSync✓ Correct
  • B. AWS Snowmobile
  • C. Amazon SNS
  • D. AWS Batch
Explanation

AWS DataSync efficiently and incrementally transfers and synchronizes file/object data between on-premises storage and AWS over the network. Snowmobile (B) is for exabyte-scale one-time physical transfer, SNS (C) is pub/sub messaging, and Batch (D) runs compute jobs.
