A company uses Amazon ElastiCache for Redis to cache frequently accessed data. The cache cluster is a single node (cache.r5.large). Over time, the cache hit ratio has decreased, and the CPU utilization is consistently above 80%. What should a solutions architect do to improve performance?

A company uses Amazon S3 to store critical data. They need to ensure that data is automatically replicated to another AWS Region for disaster recovery. Which configuration meets this requirement with minimal operational overhead?

A company runs a containerized application on Amazon ECS with Fargate launch type. The application needs to access an S3 bucket. The ECS task role has the necessary S3 permissions. However, the application is unable to upload files to S3. What is the MOST likely cause?

A company applies the above IAM policy to an IAM user. The user attempts to upload an object to my-bucket using the AWS CLI with the command: aws s3 cp file.txt s3://my-bucket/. What is the outcome?

A company is designing a disaster recovery strategy for a multi-tier application hosted on AWS. The application uses Amazon RDS for MySQL with Multi-AZ deployment. The Recovery Time Objective (RTO) is 15 minutes and Recovery Point Objective (RPO) is 1 hour. Which solution meets these requirements with the LEAST operational overhead?

A company runs a batch processing job on Amazon EC2 instances that are part of an Auto Scaling group. The job runs every night and takes approximately 2 hours. The instances are launched using a launch template with a Spot Instance request. Recently, the job has been failing because Spot Instances are being reclaimed before the job completes. The company wants a cost-effective solution that ensures the job completes reliably. The job can handle interruptions by checkpointing. Which solution should the company implement?

A media company uses AWS CloudFront to distribute video content. They notice that some users in Europe experience high latency. CloudFront metrics show low cache hit ratios for European edge locations. The origin is an S3 bucket in us-east-1. What is the MOST effective optimization?

A healthcare company runs a HIPAA-compliant web application on AWS. The application consists of an Application Load Balancer (ALB), a fleet of Amazon EC2 instances in an Auto Scaling group, and an Amazon RDS for PostgreSQL database with Multi-AZ. The security team requires that all data in transit be encrypted using TLS 1.2 or higher. The current setup uses an SSL certificate on the ALB to terminate HTTPS, but traffic between the ALB and EC2 instances is over HTTP. The company wants to enforce end-to-end encryption without changing the application code. Which solution meets these requirements?

Refer to the exhibit.

$ aws ec2 describe-instances --region us-east-1 --filters Name=tag:Name,Values=WebServer --query 'Reservations[].Instances[].{ID:InstanceId,State:State.Name,Type:InstanceType,LaunchTime:LaunchTime}' --output table

A DevOps engineer runs the above command. The Auto Scaling group for WebServer instances has a desired count of 3, but the engineer notices that there are 5 instances with the same tag. What is the MOST likely cause?

A company uses AWS CloudFormation to deploy infrastructure. A recent deployment failed with a stack update error. The error message indicates that a resource was being updated but was in a failed state. What should the engineer do to resolve this issue?

A company has an Amazon S3 bucket that stores sensitive data. The company wants to ensure that all data in the bucket is encrypted at rest. Which action should the Solutions Architect take?

A company runs a web application on EC2 instances behind an Application Load Balancer. The application stores session state in an Amazon ElastiCache Redis cluster. During a traffic spike, the Redis cluster's CPU utilization reaches 90%, causing increased latency. The company wants to reduce the load on Redis without changing the application code. Which solution should the company implement?

A company uses Amazon DynamoDB for a gaming application. The table has a partition key of user_id and a sort key of timestamp. During a new game launch, the table experiences throttling on a few partitions. The company wants to improve the partition distribution. Which TWO actions should the company take? (Choose two.)

A company uses Amazon DynamoDB for a gaming application. During a new game launch, they experience higher than expected latency on write operations. The table has on-demand capacity. What is the best way to improve write performance?

A company runs a web application on EC2 instances in an Auto Scaling group. The application stores session data in an Amazon ElastiCache for Redis cluster. The operations team reports that after scaling events, users lose their sessions. Which TWO actions should the Solutions Architect take to resolve this issue?

A company runs a containerized microservices application on Amazon ECS using Fargate. The application includes a service that processes messages from an Amazon SQS queue. The service is CPU-bound and takes longer to process messages as the queue depth increases. The team wants to automatically scale the number of tasks based on the queue depth. Which solution is MOST effective?

A startup runs a containerized microservices application on Amazon ECS with Fargate. They use an Application Load Balancer to distribute traffic. The application consists of 10 services, each with its own ECS service. Recently, the startup launched a marketing campaign and traffic increased 10x. The application started returning HTTP 503 errors. The ECS service metrics show that the number of running tasks is at the maximum desired count for each service. The ALB target group health checks are failing intermittently. The startup needs to handle the increased traffic and prevent 503 errors. What should they do?

A company is running a web application on AWS using an Application Load Balancer (ALB) in front of an Auto Scaling group of EC2 instances. The application experiences periodic traffic spikes that cause increased latency. The company wants to implement a solution to automatically adjust capacity in anticipation of traffic changes. What should a solutions architect do?

A company has a monolithic application running on a single Amazon RDS for MySQL DB instance. The application is experiencing performance issues due to heavy read traffic. The company wants to implement a solution that offloads read traffic with minimal application changes. What should a solutions architect do?
