SAP-C02 Accelerate Workload Migration and Modernization Practice Test 15 — 15 Questions

Question 1

A company is migrating a critical database server to Amazon EC2. The root volume (EBS) is configured with DeleteOnTermination=false. After migration, the company needs to ensure that if the EC2 instance fails, a new instance can be quickly launched using the same data. The company takes regular snapshots of the volume. Which statement is correct regarding the root volume's behavior?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

The root volume will persist after instance termination and can be attached to another instance.. When DeleteOnTermination is set to false, the root volume persists after the EC2 instance is terminated. This allows the volume to be attached to another instance, enabling quick recovery. Option A is incorrect because the root volume can be used as a boot volume for a new instance when attached. Option B is incorrect because the volume is not automatically deleted; deletion only occurs when DeleteOnTermination is true. Option D is incorrect because snapshots are independent of the DeleteOnTermination setting and are not automatically deleted upon instance termination.

Answer

The root volume cannot be used as a boot volume for a new instance.

Answer

The root volume will be automatically deleted when the instance is terminated.

Answer

Snapshots of the volume will be automatically deleted when the instance is terminated.

Question 2

Question 4

A company is migrating a monolithic application to AWS and wants to modernize it into microservices. The application currently uses a single relational database. Which migration strategy is most appropriate to minimize risk while starting the modernization process?

Accepted Answer

Incremental migration using the Strangler Fig pattern. The Strangler Fig pattern (Option A) is the most appropriate strategy because it allows incremental replacement of monolithic components with microservices, reducing the risk associated with a full rewrite or big bang migration. Option B (big bang migration to containers) is risky as it requires simultaneous migration of all components. Option C (replatform to Amazon RDS) only changes the database platform without addressing application architecture. Option D (rehost using VM Import/Export) simply lifts and shifts the monolith without modernization.

Answer

Big bang migration of the entire application to containers

Answer

Replatform to Amazon RDS for MySQL

Answer

Rehost the application using AWS VM Import/Export

Question 5

A company is migrating a .NET application from Windows Server to AWS. The application uses Microsoft SQL Server. The company wants to reduce licensing costs and minimize operational overhead. Which migration strategy should be recommended?

Accepted Answer
