SAP-C02 Accelerate Workload Migration and Modernization Practice Test 18 — 15 Questions

Question 1

A company is migrating a monolithic application to AWS. The application currently runs on a single on-premises server with a MySQL database. The company wants to reduce operational overhead and improve scalability. Which combination of AWS services should the company use?

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

Accepted Answer

Use AWS Elastic Beanstalk to deploy the application and Amazon RDS for MySQL as the database.. AWS Elastic Beanstalk automates application deployment, capacity provisioning, load balancing, and scaling, reducing operational overhead. Amazon RDS for MySQL manages the database, providing scalability and reducing administrative tasks. Option A is incorrect because while ECS with Fargate and Aurora Serverless can reduce overhead, containerizing a monolithic application requires refactoring and may not be straightforward; Elastic Beanstalk is more suitable for a lift-and-shift migration of a monolithic app. Option B is incorrect because DynamoDB is a NoSQL database and not compatible with the existing MySQL database without significant schema changes, and AWS Lambda is event-driven and not ideal for a monolithic application. Option C is incorrect because running the application on EC2 instances still requires manual management of operating system patches, scaling, and availability, which does not reduce operational overhead as much as Elastic Beanstalk.

Answer

Containerize the application and run on Amazon ECS with AWS Fargate, and use Amazon Aurora Serverless for MySQL.

Answer

Migrate the database to Amazon DynamoDB and host the application on AWS Lambda.

Answer

Host the application on Amazon EC2 and use Amazon RDS for MySQL.

Question 2

A company is migrating a legacy application to AWS using the rehost (lift-and-shift) strategy. The application uses a proprietary database that is not supported by Amazon RDS. The company wants to automate the migration of multiple servers and minimize downtime. Which AWS service should be used to automate the server migration?

Accepted Answer

AWS Application Migration Service (AWS MGN).. AWS Application Migration Service (MGN) automates lift-and-shift with minimal downtime. Option A is wrong because AWS CloudFormation is for infrastructure provisioning, not migration. Option C is wrong because AWS Server Migration Service (SMS) is older and less automated compared to MGN. Option D is wrong because AWS Database Migration Service (DMS) is for databases, not servers.

Answer

AWS CloudFormation to recreate the server configuration.

Answer

AWS Server Migration Service (SMS).

Answer

AWS Database Migration Service (AWS DMS) for the database and manual server migration.

Question 3

A company is migrating a web application to AWS and wants to use a blue/green deployment strategy to minimize downtime. The application runs on EC2 instances behind an Application Load Balancer (ALB). Which approach should be used?

Accepted Answer

Create a new target group for the green environment, register the new instances, test, and then modify the ALB listener rule to forward traffic to the green target group.. Blue/green deployment involves creating a new target group for the green environment, registering the new instances, testing, and then modifying the ALB listener rule to forward traffic to the green target group. Option A is wrong because stopping old instances before starting new ones would cause downtime. Option B is wrong because an in-place update of the Auto Scaling group would cause downtime. Option D is wrong because using a different ALB and updating DNS is not a typical blue/green deployment with ALB; it adds unnecessary complexity and may cause delays.

Answer

Stop the old instances, start the new instances, and update the ALB target group.

Answer

Use an AWS CloudFormation stack update to replace the Auto Scaling group and instances in place.

Answer

Deploy the new instances behind a different ALB and update DNS to point to the new ALB.

Question 4

A company is migrating a batch processing workload to AWS. The workload runs on a scheduled basis and processes large files from an on-premises NFS share. The company wants to use AWS services to replace the on-premises server and minimize operational overhead. Which solution is MOST suitable?

Accepted Answer

Mount the on-premises NFS share to Amazon EFS using AWS Direct Connect, and use AWS Batch with AWS Fargate to process the files.. AWS Batch with AWS Fargate is a serverless compute service that integrates with Amazon EFS. By mounting the on-premises NFS share to EFS via AWS Direct Connect, files are accessible in AWS without copying. AWS Batch can then process the files on a scheduled basis, minimizing operational overhead. Option A is wrong because AWS Lambda has execution time and file size limits, and directly reading from NFS over VPN may be unreliable. Option C is wrong because Snowball Edge is a one-time transfer tool, not suitable for ongoing scheduled processing. Option D is wrong because while DataSync can copy files to S3, triggering Lambda has similar limitations, and using EC2 adds management overhead.

Answer

Use AWS Lambda to directly read from the NFS share over VPN and process the files.

Answer

Use AWS Snowball Edge to transfer files to Amazon S3 and then process with EC2 instances.

Answer

Use AWS DataSync to copy files to Amazon S3 and trigger an AWS Lambda function to process.

Question 5

A company is migrating a stateful application to AWS. The application uses sticky sessions (session affinity) on the current on-premises load balancer. The company wants to use an Application Load Balancer (ALB) in AWS. Which feature should be enabled?

Accepted Answer

Sticky sessions (session affinity) using a cookie generated by the load balancer.. ALB supports sticky sessions (session affinity) using a cookie generated by the load balancer, which meets the requirement to maintain session state from the on-premises environment. Option A (connection draining) is used to allow in-flight requests to complete during instance deregistration, not for session affinity. Option C (health checks) ensures traffic is only sent to healthy instances, but does not maintain session stickiness. Option D (cross-zone load balancing) distributes traffic evenly across all availability zones, but does not affect session affinity.

Answer

Connection draining (deregistration delay).

Answer

Health checks to ensure only healthy instances receive traffic.

Answer

Cross-zone load balancing.

Question 6

A company is migrating a critical application to AWS using a rehost (lift-and-shift) approach. The application consists of a web tier and a database tier. The company wants to ensure high availability and disaster recovery. Which TWO actions should the company take? (Choose TWO.)

Accepted Answer

Deploy the web tier across multiple Availability Zones.. The correct answers are B and C. Deploying the web tier across multiple Availability Zones provides high availability within a region. Using Amazon RDS Multi-AZ provides automatic failover for the database, ensuring high availability. Option A is incorrect because Auto Scaling across multiple regions is not typical for a lift-and-shift migration and adds unnecessary complexity; cross-region deployment is more suited for disaster recovery, not high availability within a rehost. Option D is incorrect because RDS read replicas are for scaling read traffic, not for high availability or automatic failover. Option E is incorrect because using a single Availability Zone for the database creates a single point of failure and does not provide high availability.

Answer

Configure Amazon EC2 Auto Scaling to launch instances across multiple AWS Regions.

Answer

Use Amazon RDS read replicas to offload read traffic.

Answer

Use a single Availability Zone for the database to reduce latency.

Question 7

A company is migrating a large-scale application to AWS. The application uses a message queue for decoupling components. The current on-premises solution uses RabbitMQ. The company wants a managed service that supports message durability and at-least-once delivery. Which THREE AWS services meet these requirements? (Choose THREE.)

Accepted Answer

Amazon MQ (managed RabbitMQ broker).. Options B, C, and E are correct. Amazon MQ is a managed message broker service that supports RabbitMQ, providing message durability and at-least-once delivery. Amazon SQS FIFO queues guarantee exactly-once processing while also offering at-least-once delivery and durability. Amazon SQS standard queues provide at-least-once delivery and durability. Option A is incorrect because Amazon SNS is a pub/sub messaging service, not a queue, and does not support the same durability and delivery semantics as a message queue. Option D is incorrect because Amazon Kinesis Data Streams is designed for real-time streaming data ingestion, not as a traditional message queue, and does not guarantee at-least-once delivery in the same way.

Answer

Amazon Simple Notification Service (SNS) topic.

Answer

Amazon Kinesis Data Streams.

Question 8

A company is migrating an on-premises application to AWS. The application stores files on a Windows file server. The company wants to replace the file server with a managed AWS service that supports SMB protocol and integrates with Active Directory. Which TWO AWS services should the company consider? (Choose TWO.)

Accepted Answer

Amazon FSx for Windows File Server.. The correct options are D and E. Amazon FSx for Windows File Server (D) is a fully managed Windows file server that supports the SMB protocol and integrates with Active Directory. AWS Storage Gateway File Gateway (E) provides on-premises access to cloud storage via SMB and can integrate with Active Directory. Option A (EBS) is block storage, not a file server. Option B (EFS) uses NFS, not SMB. Option C (S3 with S3 File Gateway) does not support SMB natively; S3 File Gateway only presents objects as files via NFS or SMB, but it is not a managed SMB file server like FSx.

Answer

Amazon Elastic Block Store (EBS).

Answer

Amazon Elastic File System (EFS).

Answer

Amazon S3 with S3 File Gateway.

Question 9

A company is migrating a monolithic application to AWS. The application currently runs on a single on-premises server with a MySQL database. The company wants to reduce operational overhead and improve scalability. Which combination of AWS services should the company use?

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

Accepted Answer

Store session data in Amazon ElastiCache for Redis.. Amazon ElastiCache for Redis provides a fast, in-memory data store that can be shared across multiple containers, enabling horizontal scaling and fault tolerance. Option C (sticky sessions) ties a client to a specific container, preventing true statelessness and causing uneven load distribution. Option B (Amazon S3) has high latency unsuitable for session data. Option D (Amazon DynamoDB) is a NoSQL database that can store sessions but is slower and more costly than a dedicated caching layer like Redis for session management.

Answer

Use Amazon S3 to store session data.

Answer

Use sticky sessions (session affinity) on the Application Load Balancer.

Answer

Migrate session data to Amazon DynamoDB.

Question 10

A company is using AWS Application Migration Service (MGN) to migrate hundreds of on-premises servers to AWS. After the migration, some servers fail a health check. What is the most efficient way to remediate the failed servers?

Accepted Answer

Launch test instances from MGN, diagnose the issues, then update the source servers and perform a final cutover.. It follows the recommended MGN workflow for remediation: launch test instances to identify issues, fix them on the source server, and then perform a final cutover. Option B is inefficient as it restarts the entire replication and cutover process without testing. Option C is incorrect because restoring from a backup AMI is not part of the MGN migration process and does not allow iterative fixes. Option D is wrong because CloudEndure Migration is the former name of MGN and is not a separate service for re-migration.

Answer

Rerun the MGN replication and perform a new cutover.

Answer

Restore the servers from the latest AMI and re-run the health check.

Answer

Use AWS CloudEndure Migration to re-migrate the servers.

Question 11

A company is refactoring a legacy .NET application to run on AWS Lambda. The application currently uses Windows authentication and Active Directory. Which approach should the company use to support authentication in the new architecture?

Accepted Answer

Use AWS Directory Service for Microsoft Active Directory and connect Lambda to the directory via VPC.. B is correct because AWS Directory Service for Microsoft Active Directory allows Lambda functions to authenticate users against an existing Active Directory. By connecting the Lambda function to the directory via a VPC, the function can perform Windows authentication for the refactored .NET application. Option A is incorrect because Amazon Cognito user pools are designed for external identity providers, not for Windows AD authentication. Option C is incorrect because IAM roles are used for granting AWS service permissions, not for authenticating users with Windows credentials. Option D is incorrect because STS issues temporary tokens for AWS API access, not for Windows authentication.

Answer

Use Amazon Cognito user pools for authentication.

Answer

Use AWS Identity and Access Management (IAM) roles to authenticate users.

Answer

Use AWS Security Token Service (STS) to issue tokens for authentication.

Question 12

A company is migrating a critical application from on-premises to AWS using a lift-and-shift approach. The application requires consistent low-latency access to an on-premises database. Which network solution should the company implement to meet the latency requirement during the migration?

Accepted Answer

Establish an AWS Direct Connect connection between the on-premises data center and AWS.. D is correct because AWS Direct Connect provides dedicated, consistent low-latency connectivity from on-premises to AWS, meeting the latency requirement. A is wrong because a site-to-site VPN over the internet introduces variability and inconsistent latency due to internet routing. B is wrong because VPC peering is for connecting VPCs within AWS, not for on-premises connectivity. C is wrong because AWS Client VPN is designed for individual client connections, not for consistent application-level latency.

Answer

Set up a site-to-site VPN over the internet.

Answer

Create a VPC peering connection between the on-premises network and AWS VPC.

Answer

Use AWS Client VPN to connect from the application servers.

Question 13

A company is modernizing a legacy application by breaking it into microservices. The application has a complex set of dependencies and requires gradual migration. Which design pattern should the company use?

Accepted Answer

Strangler Fig pattern. (Strangler Fig pattern) because it allows incremental replacement of legacy system functionality with microservices, enabling gradual migration despite complex dependencies. Option A (Blue/Green deployment) is a deployment strategy, not a migration pattern. Option B (Saga pattern) is for managing distributed transactions, not incremental replacement. Option D (Circuit Breaker) is a fault-tolerance pattern.

Answer

Blue/Green deployment pattern

Answer

Saga pattern

Answer

Circuit Breaker pattern

Question 14

A company is migrating a legacy application from an on-premises data center to AWS. The application uses a proprietary network protocol that is not supported by AWS Application Migration Service. What should the company do to migrate this application?

Accepted Answer

Perform a manual rehost migration using Amazon EC2 and custom AMIs.. D is correct because performing a manual rehost migration using Amazon EC2 and custom AMIs allows the company to migrate the legacy application without depending on AWS Application Migration Service (MGN), which does not support the proprietary protocol. This approach replicates the on-premises environment in AWS. A is incorrect because refactoring the application to use standard protocols would require significant code changes and is not necessary for migration. B is incorrect because the 7 Rs strategy is a framework for evaluating migration approaches, not a specific solution to the protocol incompatibility. C is incorrect because AWS Application Migration Service with a network bridge appliance does not address the lack of support for the proprietary protocol.

Answer

Refactor the application to use standard protocols before migration.

Answer

Use the 7 Rs migration strategy to evaluate other options.

Answer

Use AWS Application Migration Service with a network bridge appliance.

Question 15

A company is migrating a large-scale Hadoop cluster to Amazon EMR. The migration plan includes moving data from HDFS to Amazon S3. The company wants to minimize costs and ensure data durability. Which approach should the company use?

Accepted Answer

Use Apache DistCp to copy data from HDFS to S3.. B is correct because DistCp is designed for efficient HDFS-to-S3 transfers, and S3's 99.999999999% durability meets requirements. A is wrong because VPN and rsync are not optimized for large-scale data transfer to S3. C is wrong because Snowball Edge adds latency and is not necessary for data already in the cluster. D is wrong because AWS DMS is for databases, not file systems.

Answer

Set up a VPN connection and use rsync to copy data to S3.

Answer

Use AWS Snowball Edge to physically transfer data from the cluster.

Answer

Use AWS Database Migration Service (DMS) to migrate the data to S3.
