Question 10 (Exam Pool A)

A solutions architect is evaluating the reliability of a recently migrated application running on AWS. The front end is hosted on Amazon S3 and accelerated by Amazon CloudFront. The application layer is running in a stateless Docker container on an Amazon EC2 On-Demand Instance with an Elastic IP address. The storage layer is a MongoDB database running on an EC2 Reserved Instance in the same Availability Zone as the application layer.

Which combination of steps should the solutions architect take to eliminate single points of failure with minimal application code changes? (Select TWO.)

Select all that apply, then click Submit answer.

  • ○

    Create a REST API in Amazon API Gateway and use AWS Lambda functions as the application layer.
  • ○

    Create an Application Load Balancer and migrate the Docker container to AWS Fargate.
  • ○

    Migrate the storage layer to Amazon DynamoD8.
  • ○

    Migrate the storage layer to Amazon DocumentD8 (with MongoDB compatibility).
  • ○

    Create an Application Load Balancer and move the storage layer to an EC2 Auto Scaling group.
Question 11 (Exam Pool A)

A group of research institutions and hospitals are in a partnership to study 2 PBs of genomic data. The institute that owns the data stores it in an Amazon S3 bucket and updates it regularly. The institute would like to give all of the organizations in the partnership read access to the data. All members of the partnership are extremety cost-conscious, and the institute that owns the account with the S3 bucket is concerned about covering the costs tor requests and data transfers from Amazon S3.

Which solution allows for secure datasharing without causing the institute that owns the bucket to assume all the costs for S3 requests and data transfers'?

Select an option, then click Submit answer.

  • ○

    Ensure that all organizations in the partnership have AWS accounts. In the account with the S3 bucket, create a cross-account role for each account in the partnership that allows read access to the data. Have the organizations assume and use that read role when accessing the data.
  • ○

    Ensure that all organizations in the partnership have AWS accounts. Create a bucket policy on the bucket that owns the data The policy should allow the accounts in the partnership read access to the bucket. Enable Requester Pays on the bucket. Have the organizations use their AWS credentials when accessing the data.
  • ○

    Ensure that all organizations in the partnership have AWS accounts. Configure buckets in each of the accounts with a bucket policy that allows the institute that owns the data the ability to write to the bucket Periodically sync the data from the institute's account to the other organizations. Have the organizations use their AWS credentials when accessing the data using their accounts

Question 12 (Exam Pool B)

A greeting card company recently advertised that customers could send cards to their favourite celebrities through the company's platform Since the advertisement was published, the platform has received constant traffic from 10.000 unique users each second.

The platform runs on m5.xlarge Amazon EC2 instances behind an Application Load Balancer (ALB) The instances run in an Auto Scaling group and use a custom AMI that is based on Amazon Linux. The platform uses a highly available Amazon Aurora MySQL DB cluster that uses primary and reader endpoints The platform also uses an Amazon ElastiCache for Redis cluster that uses its cluster endpoint

The platform generates a new process for each customer and holds open database connections to MySQL for the duration of each customer's session However, resource usage for the platform is low.

Many customers are reporting errors when they connect to the platform Logs show that connections to the Aurora database are failing Amazon CloudWatch metrics show that the CPU load is tow across the platform and that connections to the platform are successful through the ALB.

Which solution will remediate the errors MOST cost-effectively?

Select an option, then click Submit answer.

  • ○

    Set up an Amazon CloudFront distribution Set the ALB as the origin Move all customer traffic to the CloudFront distribution endpoint
  • ○

    Use Amazon RDS Proxy Reconfigure the database connections to use the proxy
  • ○

    Increase the number of reader nodes in the Aurora MySQL cluster
  • ○

    Increase the number of nodes in the ElastiCache for Redis cluster
