    Study Notes

    AWS Solutions Architect Practice Exams - Questions

    • A company using AWS S3 buckets wants to ensure unauthorized configuration changes don't occur. To achieve this, they should enable AWS Config with appropriate rules.
    • A company needs to allow a product manager without an AWS account to access an Amazon CloudWatch dashboard. Creating an IAM user specifically for the product manager, attaching the CloudWatchReadOnlyAccess managed policy, and sharing the dashboard URL with the product manager is the best solution adhering to least privilege.
    • For an application deployed across different AWS accounts managed by AWS Organizations, the recommended SSO solution is to use AWS Organizations to manage user credentials and policies for all accounts.
    • A company running an image-processing application in a single VPC across multiple Availability Zones, using a single NAT gateway for S3 communication faces data transfer costs. The most cost-effective way to avoid regional data transfer charges is to deploy a gateway VPC endpoint for Amazon S3.
    • To ensure an ingestion workflow that includes an SNS topic and Lambda function can handle occasional network connectivity issues, implement the following:
      • Create an Amazon SQS queue and subscribe it to the SNS topic.
      • Modify the Lambda function to read from the SQS queue.
    • A company's marketing application using SFTP for data upload needs to handle traffic spikes efficiently. Using a DynamoDB table in on-demand capacity mode provides flexibility and adapts to quick traffic changes.
    • To securely share an encrypted AMI with an MSP Partner's AWS account, the solutions architect should modify the launchPermission property of the AMI to share it with the MSP Partner's account. Additionally, they should modify the KMS key policy to grant access to the MSP Partner's account for using the key.
    • For a stateless processor application that needs to handle jobs in parallel, a loosely coupled design with durable job storage is required. The best solution is to create an Amazon SNS topic to send jobs, use an Auto Scaling group with an AMI for the processor application, and store the uploaded documents in an Amazon S3 bucket with a Lifecycle policy for periodic archiving.
    • A company wants to securely connect multiple web servers to an Amazon RDS MySQL Multi-AZ DB instance while frequently rotating user credentials. The recommended solution is to store the database user credentials in AWS Secrets Manager and grant the web servers necessary IAM permissions to access Secrets Manager.
    • To handle database upgrade events where Lambda functions fail to connect to an Aurora MySQL database, the recommended solution is to provision an Amazon RDS proxy between the Lambda functions and the database. This allows the Lambda functions to continue connecting through the proxy, ensuring database connectivity during upgrades.
    • A company wants to minimize data transfer costs when sharing 3TB of data with a European marketing firm using S3 buckets. Using S3 Cross-Region Replication from the company's S3 bucket to one of the marketing firm's S3 buckets is the most cost-effective solution for data transfer between regions.
    • To secure confidential audit documents in an S3 bucket, where accidental deletion is a concern, enabling versioning and MFA Delete features on the S3 bucket is the recommended solution.
    • A company's SQL database used for storing movie data suffers from performance issues during script execution. The recommended solution is to configure the script to execute outside business hours, avoiding impact on development tasks during peak times.
