20+ practice questions focused on Migration — one of the most tested topics on the AWS Certified SAP on AWS Specialty PAS-C01 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Migration PracticeA company is migrating a legacy .NET application to AWS. The application uses Windows Authentication and relies on Active Directory for user authentication. The company wants to minimize changes to the application code. Which AWS service should be used to integrate Active Directory with the migrated application?
Explanation: AWS Directory Service for Microsoft Active Directory is the correct choice because it provides a fully managed Microsoft Active Directory in the AWS cloud, which natively supports Windows Authentication and Kerberos-based authentication without requiring any code changes. This service allows the migrated .NET application to seamlessly integrate with the existing on-premises Active Directory through a trust relationship or by extending the directory directly into AWS, preserving the application's authentication logic.
A company is migrating a 50 TB Oracle database to Amazon RDS for Oracle using AWS DMS. The source database is running on-premises and the network link has a bandwidth of 100 Mbps. The migration must complete within 5 days. What is the MOST effective approach to meet the deadline?
Explanation: The 50 TB database over a 100 Mbps link would take approximately 48 days for a full load (50 TB * 8 / 100 Mbps / 86400 seconds/day), far exceeding the 5-day deadline. AWS Snowball allows offline transfer of the full database snapshot, bypassing network bandwidth constraints, after which AWS DMS can be used for ongoing change data capture (CDC) to replicate incremental changes. This hybrid approach meets the deadline while ensuring minimal data loss.
A company is migrating a web application from an on-premises data center to AWS. The application uses a MySQL database that is 500 GB in size. The company wants to minimize downtime during the migration. Which approach should the company use?
Explanation: AWS Database Migration Service (DMS) with ongoing replication (change data capture, CDC) allows you to perform a live migration with minimal downtime. You can start a full load of the 500 GB MySQL database while the source remains operational, then enable CDC to replicate ongoing changes until you cut over to the target RDS instance, reducing the downtime window to seconds.
A company is migrating a multi-tier application to AWS. The application includes a load balancer, web servers, and an Oracle database. The migration plan includes using AWS DMS for the database. During the initial full load, the DMS task fails with an error indicating insufficient memory. The source database is on an EC2 instance with 4 GB RAM. What should the migration team do to resolve this issue?
Explanation: Option C is correct because the error 'insufficient memory' during the initial full load in AWS DMS typically indicates that the replication instance does not have enough memory to handle the data volume or LOB processing. Increasing the size of the DMS replication instance provides more memory for caching, transformation, and LOB handling, directly resolving the resource constraint without altering the source database or task structure.
A company is migrating a legacy application to AWS that requires a static IP address for client whitelisting. The application will run on EC2 instances behind an Application Load Balancer (ALB). The company wants to ensure the IP address does not change over time. What should the company do?
Explanation: Option D is correct because a Network Load Balancer (NLB) supports static IP addresses by allowing you to assign Elastic IPs directly to each of its Availability Zone subnets. This provides fixed IP endpoints for client whitelisting, while the NLB can forward traffic to the EC2 instances behind an ALB, preserving the application's architecture.

Practice all Migration questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of 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
Migration questions on the PAS-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.
The exact number varies per candidate. Migration is tested as part of the AWS Certified SAP on AWS Specialty PAS-C01 blueprint. Practicing with targeted Migration questions ensures you can handle any format or difficulty that appears.
