The company wants to optimize costs associated with encrypting S3 objects without making additional calls to AWS KMS.

Which solution will meet these requirements?

Options:

Use server-side encryption with Amazon S3 managed keys (SSE-S3).

Use an S3 Bucket Key for server-side encryption with AWS KMS keys (SSE-KMS) on the new objects.

Use client-side encryption with AWS KMS customer managed keys.

Use server-side encryption with customer-provided keys (SSE-C) stored in AWS KMS.

Question 105

A company is performing a security review of its Amazon EMR API usage. The company's developers use an integrated development environment (IDE) that is hosted on Amazon EC2 instances. The IDE is configured to authenticate users to AWS by using access keys. Traffic between the company's EC2 instances and EMR cluster uses public IP addresses.

A solutions architect needs to improve the company's overall security posture. The solutions architect needs to reduce the company's use of long-term credentials and to limit the amount of communication that uses public IP addresses.

Which combination of steps will MOST improve the security of the company's architecture? (Select TWO.)

Options:

Set up a gateway endpoint to the EMR cluster.

Set up interface VPC endpoints to connect to the EMR cluster.

Set up a private NAT gateway to connect to the EMR cluster.

Set up IAM roles for the developers to use to connect to the Amazon EMR API.

Set up AWS Systems Manager Parameter Store to store access keys for each developer.

Question 106

A company is developing a social media application. The company anticipates rapid and unpredictable growth in users and data volume. The application needs to handle a continuous high volume of user requests. User requests include long-running processes that store large amounts of user-generated content and user profiles in a relational format. The processes must run in a specific order. The company requires an architecture that can scale resources to meet demand spikes without downtime or performance degradation. The company must ensure that the components of the application can evolve independently without affecting other parts of the system. Which combination of AWS services will meet these requirements?

Options:

Deploy the application on Amazon Elastic Container Service (Amazon ECS) with the AWS Fargate launch type. Use Amazon RDS as the database. Use Amazon Simple Queue Service (Amazon SQS) to decouple message processing between components.

Deploy the application on Amazon Elastic Container Service (Amazon ECS) with the AWS Fargate launch type. Use Amazon RDS as the database. Use Amazon Simple Notification Service (Amazon SNS) to decouple message processing between components.

Use Amazon DynamoDB as the database. Use AWS Lambda functions to implement the application. Configure Amazon DynamoDB Streams to invoke the Lambda functions. Use AWS Step Functions to manage workflows between services.

Use an AWS Elastic Beanstalk environment with auto scaling to deploy the application. Use Amazon RDS as the database. Use Amazon Simple Notification Service (Amazon SNS) to decouple message processing between components.
