A company will deployed a web application on AWS. The company hosts the backend database on Amazon RDS for MySQL with a primary DB instance and five read replicas to support scaling needs. The read replicas must log no more than 1 second bahind the primary DB Instance. The database routinely runs scheduled stored procedures.As traffic on the website increases, the replicas experinces addtional lag during periods of peak lead. A solutions architect must reduce the replication lag as much as possible. The solutions architect must minimize changes to the applicatin code and must minimize ongoing overhead.Which solution will meet these requirements?Migrate the database to Amazon Aurora MySQL. Replace the read replicas with Aurora Replicas, and configure Aurora Auto Scaling. Replace the stored procedures with Aurora MySQL native functions.Deploy an Amazon ElasticCache for Redis cluser in front of the database. Modify the application to check the cache before the application queries the database. Repace the stored procedures with AWS Lambda funcions.

• Migrate the database to a MYSQL database that runs on Amazn EC2 instances. Choose large, compute optimized for all replica nodes. Maintain the stored procedures on the EC2 instances.
• Deploy an Amazon ElastiCache for Redis cluster in fornt of the database. Modify the application to check the cache before the application queries the database. Replace the stored procedures with AWS Lambda functions.
• Migrate the database to a MySQL database that runs on Amazon EC2 instances. Choose large, compute optimized EC2 instances for all replica nodes, Maintain the stored procedures on the EC2 instances.
• Migrate the database to Amazon DynamoDB, Provision number of read capacity units (RCUs) to support the required throughput, and configure on-demand capacity scaling. Replace the stored procedures with DynamoDB streams.

A company has deployed a Java Spring Boot application as a pod that runs on Amazon Elastic Kubernetes Service (Amazon EKS) in private subnets. The application needs to write data to an Amazon DynamoDB table. A solutions architect must ensure that the application can interact with the DynamoDB table without exposing traffic to the internet.Which combination of steps should the solutions architect take to accomplish this goal? (Choose two.)

• Attach an IAM role that has sufficient privileges to the EKS pod.
• Attach an IAM user that has sufficient privileges to the EKS pod.
• Allow outbound connectivity to the DynamoDB table through the private subnets' network ACLs.
• Create a VPC endpoint for DynamoDB.
• Embed the access keys in the Java Spring Boot code.

A social media company runs its application on Amazon EC2 instances behind an Application Load Balancer (ALB). The ALB is the origin for an Amazon CloudFront distribution. The application has more than a billion images stored in an Amazon S3 bucket and processes thousands of images each second. The company wants to resize the images dynamically and serve appropriate formats to clients.Which solution will meet these requirements with the LEAST operational overhead?

• Install an external image management library on an EC2 instance. Use the image management library to process the images.
• Create a CloudFront origin request policy. Use the policy to automatically resize images and to serve the appropriate format based on the User-Agent HTTP header in the request.
• Use a Lambda@Edge function with an external image management library. Associate the Lambda@Edge function with the CloudFront behaviors that serve the images.
• Create a CloudFront response headers policy. Use the policy to automatically resize images and to serve the appropriate format based on the User-Agent HTTP header in the request.

A company wants to migrate its MySQL database from on premises to AWS. The company recently experienced a database outage that significantly impacted the business.

• Create an Amazon RDS DB instance with synchronous replication to three nodes in three Availability Zones.
• Create an Amazon RDS MySQL DB instance with Multi-AZ functionality enabled to synchronously replicate the data.
• Create an Amazon RDS MySQL DB instance and then create a read replica in a separate AWS Region that synchronously replicates the data.
• Create an Amazon EC2 instance with a MySQL engine installed that triggers an AWS Lambda function to synchronously replicate the data to an Amazon RDS MySQL DB instance.

A company has a mulli-tier application that runs six front-end web servers in an Amazon EC2 Auto Scaling group in a single Availability Zone behind an Application Load Balancer (ALB). A solutions architect needs lo modify the infrastructure to be highly available without modifying the application.Which architecture should the solutions architect choose that provides high availability?

• Create an Auto Scaling group that uses three Instances across each of tv/o Regions.
• Modify the Auto Scaling group to use three instances across each of two Availability Zones.
• Create an Auto Scaling template that can be used to quickly create more instances in another Region.
• Change the ALB in front of the Amazon EC2 instances in a round-robin configuration to balance traffic to the web tier.

A company is launching a new application and will display application metrics on an Amazon CloudWatch dashboard. The company's product manager needs to access this dashboard periodically. The product manager does not have an AWS account. A solution architect must provide access to the product manager by following the principle of least privilege.Which solution will meet these requirements?

• Share the dashboard from the CloudWatch console. Enter the product manager's email address, and complete the sharing steps. Provide a shareable link for the dashboard to the product manager.
• Create an IAM user specifically for the product manager. Attach the CloudWatch Read Only Access managed policy to the user. Share the new login credential with the product manager. Share the browser URL of the correct dashboard with the product manager.
• Create an IAM user for the company's employees, Attach the View Only Access AWS managed policy to the IAM user. Share the new login credentials with the product manager. Ask the product manager to navigate to the CloudWatch console and locate the dashboard by name in the Dashboards section.
• Deploy a bastion server in a public subnet. When the product manager requires access to the dashboard, start the server and share the RDP credentials. On the bastion server, ensure that the browser is configured to open the dashboard URL with cached AWS credentials that have appropriate permissions to view the dashboard.

A company uses a popular content management system (CMS) for its corporate website. However, the required patching and maintenance are burdensome. The company is redesigning its website and wants anew solution. The website will be updated four times a year and does not need to have any dynamic content available.
