This integration means that you can control the actions your AWS IAM users and groups can take to manage your file systems (such as creating and deleting file systems).Amazon FSx is integrated with AWS Identity and Access Management (IAM).Lustre is a popular open-source parallel file system.Īlso supports concurrent access to the same file or directory from thousands of compute instances. Keyword: Concurrent Access to files + Deliver High Performance Amazon FSx –Ī high-performance file system optimized for fast processing of workloads. Which storage option should the solutions architect recommend? A.Ĭreate an Amazon S3 bucket for the application and establish an IAM role for Fargate toĬreate an Amazon FSx for Lustre file share and establish an IAM role that allows Fargate to communicate with FSx for Lustre.Ĭreate an Amazon Elastic File System (Amazon EFS) file share and establish an IAM role that allows Fargate to communicate with Amazon EFS.Ĭreate an Amazon Elastic Block Store (Amazon EBS) volume for the application and establish an IAM role that allows Fargate to communicate with Amazon EBS. This application runs on AWS Fargate and the connected storage needs to have concurrent access to files and deliver high performance. It is therefore not suitable for key-value data storage requirements.Ī solutions architect needs to design a managed storage solution for a company’s application that includes high-performance machine learning. INCORRECT: “Amazon RDS” is incorrect as this is a relational database not a No-SQL database. INCORRECT: “Amazon EC2 Auto Scaling” is incorrect as this uses EC2 instances which will incur costs even when no requests are being made. INCORRECT: “AWS Fargate” is incorrect as containers run constantly and therefore incur costs even when no requests are being made. CORRECT: “Amazon DynamoDB” is also a correct answer. This is therefore a cost effective solution for unpredictable workloads.ĬORRECT: “AWS Lambda” is a correct answer. Lambda can scale concurrent executions to meet demand easily and DynamoDB is built for key-value data storage requirements and is also serverless and easily scalable. In this case AWS Lambda can perform the computation and store the data in an Amazon DynamoDB table. Which combination of AWS services would meet these requirements? (Select TWO ) A.
The total size of the data that needs to be persisted in a backend database is currently less than 1 GB with unpredictable future growth Data can be queried using simple key-value requests. The request patterns for the service will be unpredictable and can change suddenly from 0 requests to over 500 per second. A solutions architect is designing a new service behind Amazon API Gateway.
