SAP-C02 Accelerate Workload Migration and Modernization Practice Test 17 — 15 Questions

Question 1

A company is planning to migrate a web application to AWS. The application currently runs on a single on-premises server with a few thousand users. The company wants to use a managed container service and minimize operational overhead. Which AWS service should the company use to run the application?

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

Accepted Answer

Amazon ECS with AWS Fargate. Amazon ECS with AWS Fargate is a managed container service that eliminates the need to manage underlying EC2 instances, reducing operational overhead. Option A (Amazon EKS) is wrong because it is Kubernetes-based and more complex to manage, which does not align with minimizing operational overhead. Option B (AWS Lambda) is wrong because it is designed for short-running functions, not for running a web application as a container. Option C (Amazon EC2) is wrong because it requires manual management of instances and containers, increasing operational overhead.

Answer

Amazon EKS

Answer

AWS Lambda

Answer

Amazon EC2

Question 2

A company is migrating a critical application from on-premises to AWS. The application uses a shared file system for user uploads and logs. The company wants a highly available, durable, and low-latency solution. Which AWS storage service should the company use?

Accepted Answer

Amazon EFS. Amazon EFS provides a shared NFS file system with high availability and durability, making it suitable for user uploads and logs. Option B (Amazon EBS) is block storage and not shared across instances. Option C (Amazon FSx for Windows File Server) is designed for Windows workloads and not ideal for general Linux-based applications. Option D (Amazon S3) is object storage, not a shared file system.

Answer

Amazon EBS

Answer

Amazon FSx for Windows File Server

Answer

Amazon S3

Question 3

A company is migrating a multi-tier application to AWS. The application has a web tier, application tier, and database tier. The company wants to use AWS services to improve scalability and reduce costs. Currently, the on-premises infrastructure is underutilized. What is the most cost-effective migration strategy?

Accepted Answer

Rehost (lift-and-shift) to Amazon EC2 using AWS Application Migration Service, then right-size instances and purchase Reserved Instances.. The most cost-effective strategy for a migration with underutilized on-premises infrastructure is to lift-and-shift to EC2, right-size the instances to match actual usage, and purchase Reserved Instances to save costs. This approach minimizes changes and leverages AWS discounts. Options A and B involve rearchitecting or replatforming which are more costly and time-consuming. Option D does not consider right-sizing and leads to overspending.

Answer

Refactor the application to run on containers using Amazon EKS with Fargate.

Answer

Replatform the web tier to AWS Elastic Beanstalk and the database to Amazon RDS.

Answer

Purchase compute-heavy EC2 instances to handle peak loads and use On-Demand pricing.

Question 4

A company is migrating an application that uses a commercial database to Amazon RDS. The database size is 500 GB. Which migration approach minimizes downtime?

Accepted Answer

Use AWS Database Migration Service (AWS DMS) with ongoing replication (change data capture).. AWS Database Migration Service (AWS DMS) with ongoing replication (change data capture) allows the source database to remain fully operational during migration, with only a brief downtime during the final cutover. This minimizes overall downtime. Option A is incorrect because using native database tools for export and import requires taking the source database offline for the duration of the export and import. Option B is incorrect because AWS Snowball Edge is an offline data transfer device; it requires copying database files to the device and shipping it, which does not support ongoing replication and results in significant downtime. Option D is incorrect because copying database files to Amazon S3 and restoring to RDS involves creating a backup of the database, which can cause downtime, and the restore process also takes time.

Answer

Use native database tools to export and import data.

Answer

Use AWS Snowball Edge to transfer the database files.

Answer

Copy database files to Amazon S3 and restore to RDS.

Question 5

A company is migrating a stateful application to AWS. The application runs on a single on-premises server and uses local storage for persistent data. The company wants to achieve high availability and scalability. Which migration approach should the company use?

Accepted Answer

Refactor the application to store state in Amazon ElastiCache or Amazon DynamoDB.. The application is stateful and needs high availability and scalability. Refactoring to store state in managed services like Amazon ElastiCache or DynamoDB decouples state from compute, allowing compute to scale and be replaced without data loss. Option A is wrong: while an ALB with sticky sessions distributes traffic, it ties sessions to specific instances, making scaling and failover complex and not fully HA. Option B is wrong: a single EC2 instance is a single point of failure and cannot scale. Option D is wrong: EBS snapshots are for backup/disaster recovery, not real-time HA or state persistence during scaling. Only option C properly addresses state management for HA and scalability.

Answer

Use multiple EC2 instances behind an Application Load Balancer with sticky sessions.

Answer

Lift and shift to a single Amazon EC2 instance with an EBS volume.

Answer

Use an EC2 Auto Scaling group with lifecycle hooks to persist state to EBS snapshots.

Question 6

A company is migrating a critical application to AWS. The migration plan includes a pilot light strategy. The company has set up a small replica of the environment in AWS. During a disaster, the company wants to quickly provision the full production environment. Which AWS service is best suited for this purpose?

Accepted Answer

AWS CloudFormation. AWS CloudFormation is the best service for this scenario because it allows you to define the entire infrastructure as code in templates, which can be stored and then quickly executed to provision the full production environment during a disaster. This aligns with the pilot light strategy, where a small replica is already running and CloudFormation can rapidly scale it up. Option A (OpsWorks) is wrong because it is configuration management service for Chef/Puppet, not for quickly provisioning full environments. Option B (Elastic Beanstalk) is wrong because it is designed for deploying web applications, not for provisioning custom infrastructure. Option D (CodeDeploy) is wrong because it handles application deployments, not infrastructure provisioning.

Answer

AWS OpsWorks

Answer

AWS Elastic Beanstalk

Answer

AWS CodeDeploy

Question 7

A company is migrating a legacy application to AWS. The application uses a proprietary database that is not supported by Amazon RDS. The company wants to minimize changes and use a managed service. Which TWO options should the company consider? (Choose TWO.)

Accepted Answer

Run the database on Amazon EC2 with Amazon EBS volumes.. Options C and E are correct. Option C allows running the database on EC2 with EBS, providing full control and compatibility with any database engine, minimizing changes. Option E uses an AWS Marketplace third-party solution that offers a managed service for the specific database. Option A is incorrect because Amazon RDS does not support custom engines; it only supports specific database engines. Option B is incorrect because Amazon S3 is object storage, not a database, and S3 Select is for querying objects, not suitable as a database replacement. Option D is incorrect because DynamoDB is a NoSQL database that would require significant application changes.

Answer

Use Amazon RDS with a custom engine.

Answer

Migrate the database to Amazon S3 and use S3 Select for queries.

Answer

Convert the database to Amazon DynamoDB.

Question 8

A company is migrating a web application to AWS. The application consists of a stateless web tier, a stateful application tier, and a MySQL database. The company wants to use AWS managed services to improve scalability and reduce operational overhead. Which THREE services should the company use? (Choose THREE.)

Accepted Answer

Application Load Balancer. The correct choices are C, D, and E. For the stateless web tier, an Application Load Balancer (ALB) distributes traffic and integrates with Auto Scaling for scalability, but EC2 Auto Scaling itself is not a managed service for the database or stateful tier. The stateful application tier requires a managed in-memory caching service; Amazon ElastiCache for Redis is ideal for session state storage. The MySQL database should be migrated to Amazon RDS for MySQL, a managed relational database service that reduces operational overhead. Option A (EC2 Auto Scaling) is incorrect because it is an infrastructure-level scaling service, not a managed service for the database or stateful tier. Option B (S3) is incorrect because it is object storage, not suitable for stateful application data or session state.

Answer

Amazon EC2 Auto Scaling

Answer

Amazon S3

Question 9

A company is migrating a batch processing workload to AWS. The workload runs on a schedule and processes large files stored on a network file system. The company wants to use serverless services. Which TWO services should the company use? (Choose TWO.)

Accepted Answer

Amazon S3. Amazon S3 (Option C) is a serverless object storage service that can store the large files. AWS Lambda (Option E) is a serverless compute service that can process the files, for example by triggering on S3 events. Options A (Amazon EMR) requires a cluster of EC2 instances and is not serverless. Option B (Amazon EC2) requires provisioning servers and is not serverless. Option D (Amazon EFS) is a managed file system that is serverless, but it does not provide compute capabilities and is not the primary serverless compute service needed for processing. Therefore, the correct answers are C and E.

Answer

Amazon EMR

Answer

Amazon EC2

Answer

Amazon EFS

Question 10

A company is migrating an application that uses an S3 bucket to store user uploads. The IAM policy above is attached to the application's IAM role. The application is experiencing permission errors when trying to list objects in the bucket. What is the most likely cause?

Accepted Answer

The policy allows ListBucket but the application is trying to list objects in a prefix that requires additional permissions.. The policy grants s3:ListBucket on the bucket resource, but it may include a condition that restricts listing to a specific prefix (e.g., s3:prefix). If the application is trying to list objects in a different prefix, the request fails with a permission error. Listing objects requires the s3:ListBucket permission on the bucket, and if the policy has a prefix condition, the application must use the allowed prefix. Therefore, the most likely cause is that the application is attempting to list objects in a prefix that is not permitted by the policy's conditions.

Answer

The resource ARN for the s3:ListBucket action is incorrect. It should be arn:aws:s3:::example-bucket/*.

Answer

The policy is missing the s3:GetObject action on the bucket itself.

Answer

The policy needs a condition to restrict access to specific IP addresses.

Question 11

A company is migrating a web application to AWS. The application runs on EC2 instances behind an Application Load Balancer. The exhibit shows the current running instances. The company wants to ensure high availability across multiple Availability Zones. Which action should the company take?

Accepted Answer

Change the m5.xlarge instance in us-east-1c to an m5.large in us-east-1c or move it to another AZ.. The current instance distribution shows an m5.large in us-east-1b (or similar) and an m5.xlarge in us-east-1c, which is inconsistent. To ensure high availability across multiple Availability Zones, the company should either change the m5.xlarge to an m5.large to match instance types, or move it to a different AZ to better distribute instances. This avoids a single point of failure and ensures balanced capacity. Option A is incorrect because adding more instances to us-east-1a does not improve AZ diversity. Option C is incorrect because terminating the m5.xlarge and launching an m5.large in the same AZ does not change the AZ distribution. Option D is incorrect because placing all instances in a single AZ eliminates high availability.

Answer

Launch additional m5.large instances in us-east-1a.

Answer

Terminate the m5.xlarge instance in us-east-1c and launch an m5.large in the same AZ.

Answer

Place all instances in a single AZ and use an Auto Scaling group.

Question 12

A company is setting up AWS DMS to migrate a database. The trust policy above is attached to the IAM role used by DMS. When testing the connection, DMS reports an authentication error. What is the most likely cause?

Accepted Answer

The trust policy is correct, but the permissions policy attached to the role does not allow DMS to perform the necessary actions on the source and target databases.. The trust policy is correctly configured to allow the DMS service principal (dms.amazonaws.com) to assume the role, as required. However, an authentication error during connection testing typically indicates that DMS cannot successfully assume the role or that the assumed role lacks the necessary permissions to interact with the source or target databases. Since the trust policy is correct, the most likely cause is that the permissions policy attached to the role does not grant DMS the required actions (e.g., dms:TestConnection, dms:CreateEndpoint) on the database resources. Option D correctly identifies this as the issue.

Answer

The trust policy is missing a condition for the DMS replication instance.

Answer

The service principal should be dms.amazonaws.com, but it is misspelled.

Answer

The trust policy is missing a region-specific condition.

Question 13

A company is migrating a legacy on-premises .NET application to AWS. The application uses a SQL Server database. The company wants to minimize code changes and reduce licensing costs. Which migration strategy should the company choose?

Accepted Answer

Rehost the application on Amazon EC2 with SQL Server or use Amazon RDS for SQL Server with license-included pricing.. The correct answer because rehosting (lift-and-shift) to Amazon EC2 with SQL Server or Amazon RDS for SQL Server with license-included pricing minimizes code changes and reduces licensing costs. The company can migrate the .NET application as-is without significant modifications. Option A is wrong because rebuilding with AWS Lambda and RDS for MySQL would require a complete re-architecture and code changes, increasing cost and complexity. Option C is wrong because replatforming to Amazon Aurora PostgreSQL would require code changes to switch database engines and may not reduce licensing costs. Option D is wrong because refactoring to Amazon DynamoDB would require significant application changes and is not suitable for a SQL Server-based .NET application.

Answer

Rebuild the application using AWS Lambda and Amazon RDS for MySQL.

Answer

Replatform the application to use Amazon Aurora PostgreSQL.

Answer

Refactor the application to use Amazon DynamoDB.

Question 14

A company is planning to migrate 50 TB of data from on-premises to Amazon S3 over a 100 Mbps internet connection. The data is not time-sensitive and can tolerate some latency. Which migration method is MOST cost-effective and suitable?

Accepted Answer

Use AWS Snowball Edge devices to transfer the data.. AWS Snowball Edge is designed for large-scale data transfer when network bandwidth is limited, making it cost-effective for 50 TB over a 100 Mbps link. Option A is wrong because AWS DataSync over the internet would take very long (approximately 46 days) and is not optimal for such a large volume. Option B is wrong because S3 Transfer Acceleration improves speed via optimized routing but cannot overcome the 100 Mbps bandwidth cap; the transfer would still be slow. Option D is wrong because a 1 Gbps Direct Connect connection would be significantly more expensive than Snowball Edge, and since the data is not time-sensitive, physical shipment is more suitable.

Answer

Use AWS DataSync over the existing internet connection.

Answer

Enable S3 Transfer Acceleration on the destination bucket.

Answer

Provision a 1 Gbps AWS Direct Connect connection.

Question 15

A company wants to migrate a legacy Oracle database to AWS with minimal downtime. The database is 2 TB in size and runs on a single on-premises server. The company requires the ability to cut over quickly and roll back if needed. Which AWS service should be used?

Accepted Answer

AWS Database Migration Service (DMS) with ongoing replication from the source to an Amazon RDS for Oracle target.. AWS Database Migration Service (DMS) with ongoing replication enables continuous data replication from the on-premises Oracle database to Amazon RDS for Oracle, allowing minimal downtime during cutover. It also supports rollback by stopping replication and reverting to the source. Option A is incorrect because S3 Transfer Acceleration is for fast uploads to S3, not for database migration with replication. Option C is incorrect because AWS Schema Conversion Tool (SCT) handles schema conversion, not ongoing data replication. Option D is incorrect because AWS Snowball Edge is an offline data transfer device, which does not meet the minimal downtime requirement.

Answer

Use S3 Transfer Acceleration to upload the database dump directly to an EC2 instance.

Answer

AWS Schema Conversion Tool (SCT) to convert the schema and then export the data to flat files for import.

Answer

AWS Snowball Edge to copy the database files and then restore on Amazon RDS.
