A development team uses multiple AWS accounts for its development, staging, and production environments. Team members have been launching large Amazon EC2 instances that are underutilized. A solutions architect must prevent large instances from being launched in all accounts.

How can the solutions architect meet this requirement with the LEAST operational overhead?
  • A. Update the IAM policies to deny the launch of large EC2 instances. Apply the policies to all users.
  • B. Define a resource in AWS Resource Access Manager that prevents the launch of large EC2 instances.
  • C. Create an IAM role in each account that denies the launch of large EC2 instances. Grant the developers IAM group access to the role.
  • D. Create an organization in AWS Organizations in the management account with the default policy. Create a service control policy (SCP) that denies the launch of large EC2 instances, and apply it to the AWS accounts.

A company hosts an ecommerce application that stores all data in a single Amazon RDS for MySQL DB instance that is fully managed by AWS. The company needs to mitigate the risk of a single point of failure.

Which solution will meet these requirements with the LEAST implementation effort?
  • A. Modify the RDS DB instance to use a Multi-AZ deployment. Apply the changes during the next maintenance window.
  • B. Migrate the current database to a new Amazon DynamoDB Multi-AZ deployment. Use AWS Database Migration Service (AWS DMS) with a heterogeneous migration strategy to migrate the current RDS DB instance to DynamoDB tables.
  • C. Create a new RDS DB instance in a Multi-AZ deployment. Manually restore the data from the existing RDS DB instance from the most recent snapshot.
  • D. Configure the DB instance in an Amazon EC2 Auto Scaling group with a minimum group size of three. Use Amazon Route 53 simple routing to distribute requests to all DB instances.

A company wants to send all AWS Systems Manager Session Manager logs to an Amazon S3 bucket for archival purposes.

Which solution will meet this requirement with the MOST operational efficiency?
  • A. Enable S3 logging in the Systems Manager console. Choose an S3 bucket to send the session data to.
  • B. Install the Amazon CloudWatch agent. Push all logs to a CloudWatch log group. Export the logs to an S3 bucket from the group for archival purposes.
  • C. Create a Systems Manager document to upload all server logs to a central S3 bucket. Use Amazon EventBridge to run the Systems Manager document against all servers that are in the account daily.
  • D. Install an Amazon CloudWatch agent. Push all logs to a CloudWatch log group. Create a CloudWatch logs subscription that pushes any incoming log events to an Amazon Kinesis Data Firehose delivery stream. Set Amazon S3 as the destination.

A company is migrating its on-premises workload to the AWS Cloud. The company already uses several Amazon EC2 instances and Amazon RDS DB instances. The company wants a solution that automatically starts and stops the EC2 instances and DB instances outside of business hours. The solution must minimize cost and infrastructure maintenance.

Which solution will meet these requirements?
  • A. Scale the EC2 instances by using elastic resize. Scale the DB instances to zero outside of business hours.
  • B. Explore AWS Marketplace for partner solutions that will automatically start and stop the EC2 instances and DB instances on a schedule.
  • C. Launch another EC2 instance. Configure a crontab schedule to run shell scripts that will start and stop the existing EC2 instances and DB instances on a schedule.
  • D. Create an AWS Lambda function that will start and stop the EC2 instances and DB instances. Configure Amazon EventBridge to invoke the Lambda function on a schedule.

A company has a new mobile app. Anywhere in the world, users can see local news on topics they choose. Users also can post photos and videos from inside the app.

Users access content often in the first minutes after the content is posted. New content quickly replaces older content, and then the older content disappears. The local nature of the news means that users consume 90% of the content within the AWS Region where it is uploaded.

Which solution will optimize the user experience by providing the LOWEST latency for content uploads?
  • A. Upload and store content in Amazon S3. Use Amazon CloudFront for the uploads.
  • B. Upload and store content in Amazon S3. Use S3 Transfer Acceleration for the uploads.
  • C. Upload content to Amazon EC2 instances in the Region that is closest to the user. Copy the data to Amazon S3.
  • D. Upload and store content in Amazon S3 in the Region that is closest to the user. Use multiple distributions of Amazon CloudFront.
