SAP-C02 Accelerate Workload Migration and Modernization Practice Test 6 — 15 Questions

Question 1

A company is replatforming a legacy application to use AWS managed services. The application consists of a web server, an application server, and a MySQL database. Which THREE AWS services should the company use to modernize the architecture? (Choose THREE.)

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

Accepted Answer

Amazon ElastiCache. To modernize the legacy application to use AWS managed services, the company should use Amazon RDS for MySQL to replace the self-managed MySQL database, Elastic Load Balancing to distribute traffic across web/application servers, and Amazon ElastiCache to add caching for improved performance. Amazon EBS is a block storage service, not a managed compute or database service. Amazon Route 53 is a DNS service and not relevant to the application architecture modernization in this context. Amazon EC2 is an unmanaged compute service, which does not align with the goal of using managed services.

Answer

Amazon EBS

Answer

Amazon Route 53

Answer

Amazon EC2

Question 2

A company is migrating a batch processing workload to AWS. The workload runs daily and processes large files. Which TWO AWS services are most suitable for this workload? (Choose TWO.)

Accepted Answer

AWS Step Functions. AWS Batch is a purpose-built service for batch computing, handling job scheduling, scaling, and execution. AWS Step Functions orchestrates the workflow, managing dependencies, retries, and parallelism. The other options are less suitable: Amazon ECS is for container orchestration, not specifically batch; Amazon SQS is a message queue; AWS Lambda has execution time and memory limits that make it unsuitable for processing large files daily. Therefore, the two correct choices are AWS Batch and AWS Step Functions.

Answer

Amazon ECS

Answer

Amazon SQS

Answer

AWS Lambda

Question 3

Refer to the exhibit. A company has this IAM policy attached to a group. A user in the group tries to terminate an EC2 instance in us-east-1 with the tag 'Environment: staging'. What happens?

Accepted Answer

The termination is denied because the condition requires the 'Environment' tag to be 'production'.. The TerminateInstances action has a condition that requires the tag 'Environment: production'. Since the instance has 'staging', the condition is not met, so the action is denied. Options A, B, and D are incorrect because the condition explicitly requires 'production'.

Answer

The instance is terminated because the policy allows TerminateInstances.

Answer

The termination is denied because the Resource is not the instance's ARN.

Answer

The instance is terminated because the condition is not evaluated.

Question 4

Refer to the exhibit. A solutions architect runs the AWS CLI command and receives the output shown. The instance was stopped 2 hours ago. The company wants to minimize costs. What should the architect do next?

Accepted Answer

Keep the instance stopped; only storage costs apply.. When an EC2 instance is stopped, you are not charged for instance usage hours, but you continue to pay for any attached EBS volumes. Thus, keeping the instance stopped minimizes costs while retaining the instance configuration and data. Option B (terminate) would delete the instance and its attached volumes, potentially incurring data loss and additional costs for snapshots. Option C (start) would resume instance charges and EBS volume costs. Option D (hibernate) is not available from a stopped state; hibernation can only be initiated from a running instance and saves the memory state to an EBS volume, but it also incurs charges for that volume.

Answer

Terminate the instance to avoid any further charges.

Answer

Start the instance to verify it works.

Answer

Hibernate the instance to save memory state.

Question 5

Refer to the exhibit. A company creates this CloudFormation stack. After 30 days, what happens to objects with the prefix 'logs/'?

Accepted Answer

They are moved to the GLACIER storage class.. The lifecycle rule in the CloudFormation template specifies a transition to GLACIER after 30 days for objects with the prefix 'logs/'. Therefore, after 30 days, those objects are moved to GLACIER. Option A is incorrect because the lifecycle rule is set to transition, not delete. Option B is incorrect because versioning does not prevent lifecycle transitions. Option C is incorrect because expiration is not required for transition; the transition action moves objects to GLACIER after 30 days.

Answer

They are deleted because of the lifecycle rule.

Answer

They remain in Standard storage because versioning is enabled.

Answer

They are deleted after 30 days because no expiration is defined.

Question 6

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that is not supported by Amazon RDS. The migration must minimize downtime and require minimal changes to the application. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 instances and migrate the database using AWS Database Migration Service (DMS) with ongoing replication.. Rehosting (lift-and-shift) the application on Amazon EC2 allows the proprietary database to run without modification. Using AWS Database Migration Service (DMS) with ongoing replication minimizes downtime by keeping the database synchronized until cutover. Option A is incorrect because the proprietary database is not supported by Amazon RDS, so migrating to RDS is not feasible without changing the database engine. Option C is incorrect because refactoring to Amazon Aurora would require modifying the application code to use Aurora's query interface, resulting in significant changes. Option D is incorrect because replacing the database with Amazon DynamoDB would necessitate rewriting the entire database access layer, which is not minimal change.

Answer

Migrate the database to Amazon RDS with a compatible engine and modify connection strings.

Answer

Refactor the application to use Amazon Aurora and modify the code to use the Aurora query interface.

Answer

Replace the database with Amazon DynamoDB and rewrite database access layer.

Question 7

A company is planning to migrate a large-scale e-commerce platform from on-premises to AWS. The platform includes a web tier, application tier, and a MySQL database. The company needs to ensure high availability and scalability. Which combination of AWS services should the company use to modernize the application architecture while minimizing operational overhead?

Accepted Answer

Use Application Load Balancer, Amazon ECS with Fargate for both web and application tiers, and Amazon Aurora MySQL.. It uses a managed container service (ECS with Fargate) for both web and application tiers, eliminating server management overhead, and Amazon Aurora MySQL provides a MySQL-compatible, highly available, and scalable managed database. Option A is incorrect because although it includes a load balancer and ECS with Fargate for the application tier, it uses unmanaged EC2 instances for the web tier, increasing operational overhead. Option C is incorrect because it proposes DynamoDB, which is NoSQL and not suitable for a MySQL-based e-commerce platform. Option D is incorrect because it uses EC2 instances for both tiers, requiring more manual management compared to a containerized solution.

Answer

Use Elastic Load Balancer, Amazon EC2 instances for the web tier, and Amazon ECS with Fargate for the application tier, and Amazon RDS for MySQL.

Answer

Use Amazon CloudFront, Amazon EC2 instances for the application tier, and Amazon DynamoDB.

Answer

Use Amazon EC2 Auto Scaling groups for both web and application tiers, and Amazon RDS for MySQL with Multi-AZ.

Question 8

A company is migrating a monolithic application to AWS and wants to adopt a microservices architecture. The application currently runs on a single server and uses a shared MySQL database. Which AWS service can help the company decouple the microservices and enable asynchronous communication?

Accepted Answer

Amazon Simple Queue Service (SQS). Amazon Simple Queue Service (SQS) is a message queue service that enables asynchronous communication between microservices, which is essential for decoupling components in a microservices architecture. Amazon API Gateway is used for creating RESTful APIs, not for asynchronous messaging. AWS Step Functions orchestrates workflows but does not provide a message queue for asynchronous communication. Elastic Load Balancing distributes incoming traffic across targets, not for decoupling services via messaging.

Answer

Amazon API Gateway

Answer

AWS Step Functions

Answer

Elastic Load Balancing

Question 9

A company is migrating a critical application to AWS and needs to ensure that the migration has minimal downtime. The application uses a SQL Server database. The company wants to use AWS Database Migration Service (DMS) for the migration. What should the company do to minimize downtime during the database migration?

Accepted Answer

Use DMS with ongoing replication (change data capture) to keep the target database synchronized, then perform a brief cutover.. Using change data capture (CDC) with AWS DMS enables ongoing replication of changes from the source SQL Server database to the target. This keeps the target nearly synchronized, so during cutover only a brief pause is needed to apply any final changes, minimizing downtime. Option A is incorrect because enabling validation does not reduce downtime; it only verifies data integrity after migration, and truncating the target before cutover would remove all data, causing potential data loss and additional downtime. Option C is incorrect because a full load only captures a snapshot of the database at a point in time; any changes after that require a separate sync, leading to longer downtime. Option D is incorrect because manually copying remaining data after a full load migration defeats the purpose of using DMS and introduces significant downtime and risk of inconsistency.

Answer

Use DMS with validation enabled and then truncate the target before cutover.

Answer

Use DMS with full load only and schedule the migration during a maintenance window.

Answer

Perform a full load migration using DMS and then manually copy any remaining data.

Question 10

A company is migrating its on-premises data center to AWS. The company has over 200 applications, each with varying dependencies. The migration team wants to use AWS Migration Hub to track the migration progress. Which approach should the team take to ensure successful tracking and minimize manual effort?

Accepted Answer

Use AWS Application Discovery Service to discover dependencies and then use AWS Migration Hub to track the migration of each application.. AWS Application Discovery Service helps discover dependencies and collect data about on-premises servers, which is used to create a migration plan. AWS Migration Hub then tracks the migration progress of each application across multiple tools, automating tracking and minimizing manual effort. Option A is incorrect because Amazon CloudWatch dashboards monitor resource health but do not track migration progress or dependencies. Option B is incorrect because AWS Systems Manager is for operational management, not specifically for migration tracking. Option D is incorrect because manual spreadsheets are error-prone and require significant effort, defeating the purpose of using AWS tools for automation.

Answer

Use Amazon CloudWatch dashboards to monitor the health of on-premises servers.

Answer

Use AWS Systems Manager to automate the migration of each application.

Answer

Manually create a spreadsheet of all applications and their dependencies, and update it weekly.

Question 11

A company wants to migrate its on-premises file server to AWS. The file server contains 10 TB of data that changes infrequently. The company has a limited bandwidth internet connection and needs to complete the migration within one week. Which AWS service should the company use for the initial data transfer?

Accepted Answer

AWS Snowball Edge. AWS Snowball Edge. This is the best option for migrating 10 TB of data over a limited bandwidth connection within a week, as it physically transfers the data via a portable storage device, bypassing the need for network bandwidth. Option A (Amazon S3 Transfer Acceleration) is incorrect because it still relies on internet bandwidth, which is insufficient for the given timeline. Option C (AWS DMS) is for database migrations, not file servers. Option D (AWS DataSync) also requires network connectivity and bandwidth, making it unsuitable for the large initial transfer over a slow connection.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Question 12

A company is migrating a legacy .NET application to AWS. The application currently runs on Windows Server and uses a SQL Server database. The company wants to minimize licensing costs and operational overhead. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 Windows instances with SQL Server using License Mobility.. Rehost the application on Amazon EC2 Windows instances with SQL Server using License Mobility. This approach minimizes licensing costs by allowing the company to bring existing SQL Server licenses to AWS via License Mobility, avoiding new license purchases. It also minimizes operational overhead by requiring no application code changes. Option A is incorrect because replatforming to Docker containers on ECS with Windows containers adds complexity and may require modifications to the legacy application. Option C is incorrect because moving the database to Amazon RDS for SQL Server reduces operational overhead but licensing costs depend on the license model and may not be minimal. Option D is incorrect because refactoring to .NET Core on Linux requires significant rework, increasing cost and operational overhead.

Answer

Replatform using Docker containers on Amazon ECS with Windows containers.

Answer

Replatform the application by moving the database to Amazon RDS for SQL Server and the application to Elastic Beanstalk.

Answer

Refactor the application to .NET Core and deploy on Amazon Linux with SQL Server.

Question 13

A company is migrating a distributed application that uses a custom TCP protocol between components. The application is deployed on-premises across multiple servers. The company wants to use AWS without modifying the application code. Which approach should the company take to migrate the application while maintaining low latency between components?

Accepted Answer

Use Amazon EC2 instances in a Placement Group within a single VPC to ensure low latency.. Using a Placement Group ensures that EC2 instances are placed close together within the same Availability Zone, minimizing network latency and maximizing throughput for the custom TCP protocol. This allows the application to run unchanged on AWS. Option B is incorrect because Direct Connect connects on-premises to AWS, but the application components would still be separated by network distance, increasing latency. Option C is incorrect because VPC Peering connects different VPCs, which does not guarantee low latency within a single VPC. Option D is incorrect because a VPN is used for secure connectivity over the internet, which introduces higher latency and is not necessary for components within the same VPC.

Answer

Use AWS Direct Connect to connect the on-premises servers to AWS and keep the application on-premises.

Answer

Use VPC Peering to connect the application components across different VPCs.

Answer

Use a VPN connection between the on-premises environment and AWS VPC.

Question 14

A company is migrating a legacy application to AWS. The application runs on Windows Server and uses a shared file system for storage. The company wants to modernize the application by using a managed file storage service that is POSIX-compliant and can be accessed by multiple EC2 instances concurrently. Which TWO AWS services meet these requirements? (Choose TWO.)

Accepted Answer

Amazon FSx for Lustre. Amazon EFS (Option E) and Amazon FSx for Lustre (Option B) are both POSIX-compliant file systems that can be accessed concurrently by multiple EC2 instances. Option A (Amazon EBS) is block storage that can be attached to only one instance at a time (unless using multi-attach, which has limitations). Option C (Amazon S3) is object storage, not POSIX-compliant. Option D (Amazon S3 Glacier) is archival storage and not suitable for shared file system access.

Answer

Amazon EBS

Answer

Amazon S3

Answer

Amazon S3 Glacier

Question 15

A company is migrating its on-premises applications to AWS. The company has a mix of Windows and Linux servers. The migration team wants to automate the discovery of application dependencies and track the migration progress. Which TWO AWS services should the team use? (Choose TWO.)

Accepted Answer

AWS Application Discovery Service. (AWS Application Discovery Service) and Option E (AWS Migration Hub) are correct. Application Discovery Service automatically discovers application dependencies. Migration Hub tracks migration progress across multiple tools. Option A (AWS Systems Manager) manages instances but does not discover dependencies. Option B (AWS Config) tracks configuration changes but not dependencies. Option D (AWS CloudTrail) logs API calls.

Answer

AWS Systems Manager

Answer

AWS Config

Answer

AWS CloudTrail
