Amazon ElastiCache. Amazon RDS for MySQL replaces the self-managed database. Elastic Load Balancing distributes traffic. Amazon ElastiCache adds caching for performance. Option A is wrong because EC2 is not a managed service. Option D is wrong because EBS is block storage. Option E is wrong because Route 53 is DNS.

Answer

Amazon EBS

Answer

Amazon Route 53

Answer

Amazon EC2

Question 3

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 manages batch computing jobs. AWS Step Functions orchestrates workflows. Option A is wrong because Lambda has time limits. Option C is wrong because ECS is for containers, not specifically batch. Option D is wrong because SQS is for message queuing.

Amazon ECS

Answer

Amazon SQS

Answer

AWS Lambda

Question 4

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 5

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.. A stopped instance incurs charges for attached EBS volumes, but not for the instance itself. Option A is wrong because termination would delete the instance. Option B is wrong because hibernation is not possible from stopped state. Option D is wrong because starting the instance incurs costs.

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 6

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 transitions objects with prefix 'logs/' to GLACIER after 30 days. Option A is wrong because the rule is enabled. Option B is wrong because versioning is enabled but doesn't affect the transition. Option D is wrong because the transition is triggered 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 7

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.. Option B is correct because rehosting (lift-and-shift) involves moving the application as-is to Amazon EC2, which can host any database engine, and can minimize changes and downtime using tools like AWS Server Migration Service. Option A is incorrect because refactoring would require significant application changes. Option C is incorrect because replacing the database with a new one would require application modifications. Option D is incorrect because the database is not supported by RDS, so RDS cannot be used.

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 8

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.. Option C is correct because Application Load Balancer distributes traffic, Amazon ECS with Fargate runs containers without managing servers, and Amazon Aurora is a managed MySQL-compatible database with high availability and scalability. Option A is incorrect because it lacks a load balancer and uses unmanaged EC2. Option B is incorrect because it uses unmanaged EC2 for the web tier. Option D is incorrect because it uses unmanaged EC2 for the application tier.

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 9

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). Option A is correct because Amazon SQS is a message queue service that enables asynchronous communication between microservices. Option B is incorrect because API Gateway is for synchronous RESTful APIs. Option C is incorrect because ELB distributes traffic, not for messaging. Option D is incorrect because AWS Step Functions is for orchestrating workflows, not for queuing messages.

Answer

Amazon API Gateway

Answer

AWS Step Functions

Answer

Elastic Load Balancing

Question 10

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.. Option B is correct because using change data capture (CDC) with DMS allows ongoing replication from the source to the target, so when you cut over, only a brief pause is needed. Option A is incorrect because full load only captures a snapshot, requiring downtime for the final sync. Option C is incorrect as it describes a full load. Option D is incorrect because validation does not help minimize downtime.

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 11

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.. Option D is correct because using AWS Application Discovery Service to collect data about on-premises servers and their dependencies helps create a migration plan, and Migration Hub can then track progress across multiple tools. Option A is incorrect because manual tagging is error-prone and not automated. Option B is incorrect because CloudWatch is for monitoring, not tracking migration progress. Option C is incorrect because Systems Manager is for management, not specifically for migration tracking.

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 12

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. Option C is correct because AWS Snowball Edge is a physical device that can handle large data transfers over slow networks. Option A is incorrect because AWS DataSync requires network bandwidth. Option B is incorrect because AWS DMS is for databases. Option D is incorrect because S3 Transfer Acceleration speeds up transfers over the internet but still relies on bandwidth.

Answer

Amazon S3 Transfer Acceleration

Answer

AWS Database Migration Service (DMS)

Answer

AWS DataSync

Question 13

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.. Option A is correct because rehosting on Amazon EC2 with SQL Server and Windows Server licenses included through License Mobility can minimize costs and changes. Option B is incorrect because refactoring to .NET Core and SQL Server on Linux may reduce licensing costs but requires significant changes. Option C is incorrect because replacing with RDS for SQL Server may reduce operational overhead but licensing costs depend on license model. Option D is incorrect because containers add complexity and may not be suitable for legacy .NET without changes.

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 14

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.. Option D is correct because using Placement Groups with EC2 instances ensures low latency and high throughput between components, and the application can run unchanged. Option A is incorrect because VPC peering is for connectivity between VPCs, not for low latency within a VPC. Option B is incorrect because Direct Connect improves connectivity to on-premises but not within AWS. Option C is incorrect because a VPN is not needed for within AWS communication.

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.
