Which solution will meet these requirements with the LEAST operational overhead?

1. A. Store the credentials as secrets in AWS Secrets Manage
2. B. Use multi-Region secret replication for the required Regions Configure Secrets Manager to rotate the secrets on a schedule
3. C. Store the credentials as secrets in AWS Systems Manager by creating a secure string parameter Use multi-Region secret replication for the required Regions Configure Systems Manager to rotate the secrets on a schedule
4. D. Store the credentials in an Amazon S3 bucket that has server-side encryption (SSE) enabled Use Amazon EventBridge (Amazon CloudWatch Events) to invoke an AWS Lambda function to rotate the credentials
5. E. Encrypt the credentials as secrets by using AWS Key Management Service (AWS KMS) multi-Region customer managed keys Store the secrets in an Amazon DynamoDB global table Use an AWS Lambda function to retrieve the secrets from DynamoDB Use the RDS API to rotate the secrets.

A company is developing an ecommerce application that will consist of a load-balanced front end, a container-based application, and a relational database. A solutions architect needs to create a highly available solution that operates with as little manual intervention as possible.
Which solutions meet these requirements? (Select TWO.)

1. A. Create an Amazon RDS DB instance in Multi-AZ mode.
2. B. Create an Amazon RDS DB instance and one or more replicas in another Availability Zone.
3. C. Create an Amazon EC2 in stance-based Docker cluster to handle the dynamic application load.
4. D. Create an Amazon Elastic Container Service (Amazon ECS) cluster with a Fargate launch type to handle the dynamic application load.
5. E. Create an Amazon Elastic Container Service (Amazon ECS) cluster with an Amazon EC2 launch type to handle the dynamic application load.

Correct Answer: AD

* 1. Relational database: RDS
* 2. Container-based applications: ECS
"Amazon ECS enables you to launch and stop your container-based applications by using simple API calls. You can also retrieve the state of your cluster from a centralized service and have access to many familiar Amazon EC2 features."
* 3. Little manual intervention: Fargate
You can run your tasks and services on a serverless infrastructure that is managed by AWS Fargate. Alternatively, for more control over your infrastructure, you can run your tasks and services on a cluster of Amazon EC2 instances that you manage.

A company has an application that generates a large number of files, each approximately 5 MB in size. The files are stored in Amazon S3. Company policy requires the files to be stored for 4 years before they can be
deleted Immediate accessibility is always required as the files contain critical business data that is not easy to reproduce. The files are frequently accessed in the first 30 days of the object creation but are rarely accessed after the first 30 days
Which storage solution is MOST cost-effective?

1. A. Create an S3 bucket lifecycle policy to move Mm from S3 Standard to S3 Glacier 30 days from object creation Delete the Tiles 4 years after object creation
2. B. Create an S3 bucket lifecycle policy to move tiles from S3 Standard to S3 One Zone-infrequent Access (S3 One Zone-IA] 30 days from object creatio
3. C. Delete the fees 4 years after object creation
4. D. Create an S3 bucket lifecycle policy to move files from S3 Standard-infrequent Access (S3 Standard-lA) 30 from object creatio
5. E. Delete the ties 4 years after object creation
6. F. Create an S3 bucket Lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation Move the files to S3 Glacier 4 years after object carton.
