A large company recently experienced an unexpected increase in Amazon RDS and Amazon DynamoDB costs. The company needs to increase visibility into details of AWS Billing and Cost Management There are various accounts associated with AWS Organizations, including many development and production accounts There is no consistent tagging strategy across the organization, but there are guidelines in place that require all infrastructure to be deployed using AWS CloudFormation with consistent tagging. Management requires cost center numbers and project ID numbers for all existing and future DynamoDB tables and RDS instances.
Which strategy should the solutions architect provide to meet these requirements?

• A.Use Tag Editor to tag existing resources Create cost allocation tags to define the cost center and project ID and allow 24 hours for tags to propagate to existing resources.
• B.Use an AWS Config rule to alert the finance team of untagged resources Create a centralized AWS Lambda based solution to tag untagged RDS databases and DynamoDB resources every hour using a cross-account role.
• C.Use Tag Editor to tag existing resources Create cost allocation tags to define the cost center and project ID Use SCPs to restrict resource creation that do not have the cost center and project ID on the resource.
• D.Create cost allocation tags to define the cost center and project ID and allow 24 hours for tags to propagate to existing resources Update existing federated roles to restrict privileges to provision resources that do not include the cost center and project ID on the resource.

A company that uses AWS Organizations is creating several new AWS accounts. The company is setting up controls to properly allocate AWS costs to business units. The company must Implement a solution to ensure that all resources include a tag that has a key of costcenter and a value from a predefined list of business units.
The solution must send a notification each time a resource tag does not meet these criteria. The solution must not prevent the creation of resources.
Which solution will meet these requirements with the LEAST operational overhead?

• A.Create an 1AM policy for all actions that create AWS resources. Add a condition to the policy that aws:RequestTag/costcenter must exist and must contain a valid business unit value. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that monitors 1AM service events and Amazon EC2 service events for noncompliant tag policies. Configure the rule to send notifications through Amazon Simple Notification Service (Amazon SNS).
• B.Create an organization tag policy that ensures that all resources have the costcenter tag with a valid business unit value. Do not select the option to prevent operations when tags are noncompliant. Create an Amazon Event8ridge (Amazon CloudWatch Events) rule that monitors all events for noncompliant tag policies. Configure the rule to send notifications through Amazon Simple Notification Service (Amazon SNS).
• C.Create an organization tag policy that ensures that all resources have the costcenter tag with a valid business unit value. Select the option to prevent operations when tags are noncompliant Create an Amazon EventBridge (Amazon CloudWatch Events) rule that monitors all events for noncompliant tag policies. Configure the rule to send notifications through Amazon Simple Notification Service (Amazon SNS).
• D.Create an 1AM policy for all actions that create AWS resources. Add a condition to the policy that awsResourceTag/costcenter must exist and must contain a valid business unit value Create an Amazon EventBridge (Amazon CloudWatch Events) rule that monitors 1AM service events and Amazon EC2 service events for noncompliant tag policies. Configure the rule to send notifications through Amazon Simple Notification Service (Amazon SNS).

A company is hosting an image-processing service on AWS in a VPC. The VPC extends across two Availability Zones. Each Availability Zone contains one public subnet and one private subnet.
The service runs on Amazon EC2 instances in the private subnets. An Application Load Balancer in the public subnets is in front of the service. The service needs to communicate with the internet and does so through two NAT gateways. The service uses Amazon S3 for image storage. The EC2 instances retrieve approximately 1
¢' of data from an S3 bucket each day.
The company has promoted the service as highly secure. A solutions architect must reduce cloud expenditures as much as possible without compromising the service's security posture or increasing the time spent on ongoing operations.
Which solution will meet these requirements?

• A.Replace the NAT gateways with NAT instances. In the VPC route table, create a route from the private subnets to the NAT instances.
• B.Move the EC2 instances to the public subnets. Remove the NAT gateways.
• C.Set up an S3 gateway VPC endpoint in the VPC. Attach an endpoint policy to the endpoint to allow the required actions on the S3 bucket.
• D.Attach an Amazon Elastic File System (Amazon EFS) volume to the EC2 instances. Host the image on the EFS volume.

An online magazine will launch Its latest edition this month. This edition will be the first to be distributed globally. The magazine's dynamic website currently uses an Application Load Balancer in front of the web tier a fleet of Amazon EC2 instances for web and application servers, and Amazon Aurora MySQL. Portions of the website include static content and almost all traffic is read-only The magazine is expecting a significant spike m internet traffic when the new edition is launched Optimal performance is a top priority for the week following the launch Which combination of steps should a solutions architect take to reduce system response antes for a global audience? (Select TWO )

• A.Use an Aurora global database for physical cross-Region replication. Use Amazon S3 with cross-Region replication for static content and resources. Deploy the web and application tiers in Regions across the world
• B.Ensure the web and application tiers are each m Auto Scaling groups. Introduce an AWS Direct Connect connection Deploy the web and application tiers in Regions across the world
• C.Migrate the database from Amazon Aurora to Amazon RDS for MySQL. Ensure all three of the application tiers-web. application, and database-are in private subnets.
• D.Introduce Amazon Route 53 with latency-based routing and Amazon CloudFront distributions. Ensure me web and application tiers are each in Auto Scaling groups
• E.Use logical cross-Region replication to replicate the Aurora MySQL database to a secondary Region Replace the web servers with Amazon S3 Deploy S3 buckets in cross-Region replication mode

A company hosts a Git repository in an on-premises data center. The company uses webhooks to invoke functionality that runs in the AWS Cloud. The company hosts the webhook logic on a set of Amazon EC2 instances in an Auto Scaling group that the company set as a target for an Application Load Balancer (ALB). The Git server calls the ALB for the configured webhooks. The company wants to move the solution to a serverless architecture.
Which solution will meet these requirements with the LEAST operational overhead?

• A.For each webhook, create and configure an AWS Lambda function URL. Update the Git servers to call the individual Lambda function URLs.
• B.Create an Amazon API Gateway HTTP API. Implement each webhook logic in a separate AWS Lambda function. Update the Git servers to call the API Gateway endpoint.
• C.Deploy the webhook logic to AWS App Runner. Create an ALB, and set App Runner as the target. Update the Git servers to call the ALB endpoint.
• D.Containerize the webhook logic. Create an Amazon Elastic Container Service (Amazon ECS) cluster, and run the webhook logic in AWS Fargate. Create an Amazon API Gateway REST API, and set Fargate as the target. Update the Git servers to call the API Gateway endpoint.
