Sample Questions

Question #295 / 529

An application is deployed on Amazon EC2 instances within an Auto Scaling group configured with a single instance type. The instances are over-provisioned, leading to higher-than-necessary costs despite stable CPU and memory utilization. A solutions architect must implement a solution to reduce costs and improve resource utilization while minimizing future configuration adjustments. Which solution meets these requirements?

A

Identify instance types with similar compute and memory characteristics as the current type. Update the Auto Scaling group's launch template to include these instance types, enabling it to use multiple instance types.

B

Analyze the application's resource utilization data to select a more cost-effective instance type. Update the Auto Scaling group's configuration to include the new instance type and remove the original instance type.

C

Define CPU and memory requirements in a revised launch template for the Auto Scaling group, removing the current instance type. This allows AWS to automatically select the most suitable instance type based on the specifications.

D

Develop a script that dynamically retrieves cost-optimized instance types from the AWS Price List API. Update the Auto Scaling group's launch template to use these instance types.

Question #482 / 529

A company must utilize an AWS Transfer Family SFTP-enabled server linked to an Amazon S3 bucket to receive daily data feeds from a third-party vendor. The vendor encrypts the data using GNU Privacy Guard (GPG) encryption. The company requires an automated solution to decrypt the data immediately upon receipt.

The solutions architect is tasked with implementing a Transfer Family managed workflow. The company has already established an IAM service role with a policy granting access to AWS Secrets Manager and the S3 bucket. The role's trust relationship permits the transfer.amazonaws.com service to assume the role.

What should the solutions architect do next to enable automatic decryption of the data?

A

Store the GPG public key in Secrets Manager. Add a nominal step in the Transfer Family managed workflow to decrypt files. Configure GPG encryption parameters in the nominal step. Associate the workflow with the Transfer Family server.

B

Store the GPG private key in Secrets Manager. Add an exception-handling step in the Transfer Family managed workflow to decrypt files. Configure GPG encryption parameters in the exception handler. Associate the workflow with the SFTP user.

C

Store the GPG private key in Secrets Manager. Add a nominal step in the Transfer Family managed workflow to decrypt files. Configure GPG decryption parameters in the nominal step. Associate the workflow with the Transfer Family server.

D

Store the GPG public key in Secrets Manager. Add an exception-handling step in the Transfer Family managed workflow to decrypt files. Configure GPG decryption parameters in the exception handler. Associate the workflow with the SFTP user.
