Domain 2.5: Performance Objectives

A gaming company is launching a new multiplayer game. The backend uses Amazon DynamoDB. The game requires microsecond latency for read operations to ensure a smooth user experience. The read traffic is highly unpredictable and read-heavy. Which solution provides the required performance with the LEAST application code changes?

A data analytics company runs heavy machine learning workloads on Amazon EC2 instances. The workloads require massive network throughput and low latency between instances in the same cluster. They are currently using standard EC2 networking but are experiencing network bottlenecks. What is the BEST architectural change to optimize network performance?

A media streaming company delivers content globally. They are using Amazon CloudFront with an S3 origin. Users in certain remote regions are experiencing high latency because the content is not cached at their local edge location, resulting in frequent origin fetches to the central S3 bucket. How can the architect improve performance and reduce the load on the S3 origin?

A company is running a high-performance computing (HPC) workload on AWS. The workload consists of thousands of EC2 instances that need to read and write to a shared file system simultaneously. The file system must provide sub-millisecond latencies and millions of IOPS. Which storage solution should the architect choose?

A company is building a data analytics platform. They have petabytes of data in Amazon S3. They want to allow their data scientists to run complex SQL queries against this data without provisioning any infrastructure. The queries often take several minutes to run. The results of these queries need to be visualized in dashboards. Which combination of services should they use? (Select TWO)
