A solutions architect is designing an application that helps users fill out and submit registration forms. The solutions architect plans to use a two-tier architecture that includes a web application server tier and a worker tier.

The application needs to process submitted forms quickly. The application needs to process each form exactly once. The solution must ensure that no data is lost.

Which solution will meet these requirements?

A. Use an Amazon Simple Queue Service (Amazon SQS) FIFO queue between the web application server tier and the worker tier to store and forward form data.
B. Use an Amazon API Gateway HTTP API between the web application server tier and the worker tier to store and forward form data.
C. Use an Amazon Simple Queue Service (Amazon SQS) standard queue between the web application server tier and the worker tier to store and forward form data.
D. Use an AWS Step Functions workflow. Create a synchronous workflow between the web application server tier and the worker tier that stores and forwards form data.

Which solution will meet these requirements MOST cost-effectively?

A. Read the data from the tapes on premises. Stage the data in a local NFS storage. Use AWS DataSync to migrate the data to Amazon S3 Glacier Flexible Retrieval.
B. Use an on-premises backup application to read the data from the tapes and to write directly to Amazon S3 Glacier Deep Archive.
C. Order multiple AWS Snowball devices that have Tape Gateway. Copy the physical tapes to virtual tapes in Snowball. Ship the Snowball devices to AWS. Create a lifecycle policy to move the tapes to Amazon S3 Glacier Deep Archive.
D. Configure an on-premises Tape Gateway. Create virtual tapes in the AWS Cloud. Use backup software to copy the physical tape to the virtual tape.

A company has a custom application with embedded credentials that retrieves information from a database in an Amazon RDS for MySQL DB cluster. The company needs to make the application more secure with minimal programming effort. The company has created credentials on the RDS for MySQL database for the application user.

Which solution will meet these requirements?

A. Store the credentials in AWS Key Management Service (AWS KMS). Create keys in AWS KMS. Configure the application to load the database credentials from AWS KMS. Enable automatic key rotation
B. Store the credentials in encrypted local storage. Configure the application to load the database credentials from the local storage. Set up a credentials rotation schedule by creating a cron job.
C. Store the credentials in AWS Secrets Manager. Configure the application to load the database credentials from Secrets Manager. Set up a credentials rotation schedule by creating an AWS Lambda function for Secrets Manager.
D. Store the credentials in AWS Systems Manager Parameter Store. Configure the application to load the database credentials from Parameter Store. Set up a credentials rotation schedule in the RDS for MySQL database by using Parameter Store.

A company is using an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The company must ensure that Kubernetes service accounts in the EKS cluster have secure and granular access to specific AWS resources by using IAM roles for service accounts (IRSA).

Which combination of solutions will meet these requirements? (Choose two.)

A. Create an IAM policy that defines the required permissions Attach the policy directly to the IAM role of the EKS nodes.
B. Implement network policies within the EKS cluster to prevent Kubernetes service accounts from accessing specific AWS services.
C. Modify the EKS cluster's IAM role to include permissions for each Kubernetes service account. Ensure a one-to-one mapping between IAM roles and Kubernetes roles.
D. Define an IAM role that includes the necessary permissions. Annotate the Kubernetes service accounts with the Amazon ResourceName (ARN) of the IAM role.
E. Set up a trust relationship between the IAM roles for the service accounts and an OpenID Connect (OIDC) identity provider.

A company is building a cloud-based application on AWS that will handle sensitive customer data. The application uses Amazon RDS for the database, Amazon S3 for object storage, and S3 Event Notifications that invoke AWS Lambda for serverless processing.

The company uses AWS IAM Identity Center to manage user credentials. The development, testing, and operations teams need secure access to Amazon RDS and Amazon S3 while ensuring the confidentiality of sensitive customer data. The solution must comply with the principle of least privilege.

Which solution meets these requirements with the LEAST operational overhead?

A. Use IAM roles with least privilege to grant all the teams access. Assign IAM roles to each team with customized IAM policies defining specific permission for Amazon RDS and S3 object access based on team responsibilities.
B. Enable IAM Identity Center with an Identity Center directory. Create and configure permission sets with granular access to Amazon RDS and Amazon S3. Assign all the teams to groups that have specific access with the permission sets.
C. Create individual IAM users for each member in all the teams with role-based permissions. Assign the IAM roles with predefined policies for RDS and S3 access to each user based on user needs. Implement IAM Access Analyzer for periodic credential evaluation.
D. Use AWS Organizations to create separate accounts for each team. Implement cross-account IAM roles with least privilege. Grant specific permission for RDS and S3 access based on team roles and responsibilities.

A financial services company plans to launch a new application on AWS to handle sensitive financial transactions. The company will deploy the application on Amazon EC2 instances. The company will use Amazon RDS for MySQL as the database. The company’s security policies mandate that data must be encrypted at rest and in transit.

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

A. Configure encryption at rest for Amazon RDS for MySQL by using AWS KMS managed keys. Configure AWS Certificate Manager (ACM) SSL/TLS certificates for encryption in transit.
B. Configure encryption at rest for Amazon RDS for MySQL by using AWS KMS managed keys. Configure IPsec tunnels for encryption in transit.
C. Implement third-party application-level data encryption before storing data in Amazon RDS for MySQL. Configure AWS Certificate Manager (ACM) SSL/TLS certificates for encryption in transit.
