Task 3.2 Define the AWS global infrastructure

Your company is experiencing increased demand for its real-time gaming app, which requires low-latency interactions with its end-users across various geographies. To optimize for latency, your team is considering leveraging the AWS global infrastructure to deploy the application as close to the users as possible. Given that your users are spread out across urban areas in the United States as well as other global cities, which combination of AWS services and regions would best meet the low-latency requirement for both sets of users?

Task 3.4 Identify AWS database services

A gaming company has developed a new mobile game which requires fast read and write operations to maintain a real-time leaderboard. The company needs a scalable database solution that minimizes latency for their global player base. Which AWS service should they use that specializes in in-memory data storage and retrieval to serve their purpose?

A content delivery network which speeds up the distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users based on their geographic location is essential for your global application. You need to ensure low latency and high transfer speeds when your end-users access this content. Which AWS service would best fit these requirements?

Task 3.6 Identify AWS storage services

A company is looking to implement a cost-effective storage strategy for their documents, which need to be readily accessible for 30 days after creation, but their access frequency drops significantly after that period. After 90 days, documents are rarely accessed but must still be kept for legal reasons. The solution should minimize costs while retaining the ability to retrieve documents within a few hours if needed. Which of the following would be the most appropriate solution?

Task 3.7 Identify AWS artificial intelligence and machine learning (AI/ML) services and analytics services

An independent software vendor (ISV) wants to develop an application that will use a deep learning-enabled video camera to recognize and differentiate between different types of animals in real-time at a safari park. The ISV plans to send the video stream to the AWS Cloud for analysis and take advantage of AWS's AI/ML services to enhance the analytics. Which AWS service should they use together with the deep learning-enabled video camera for real-time analysis and to complete their use case effectively?

Task 3.8 Identify services from other in-scope AWS service categories

A company's remote workforce needs to securely access high-performance desktop applications from various end-user machines, including tablets and laptops, without incurring the overhead of managing physical hardware and complex licensing. The company is looking for a fully managed AWS service that can stream the applications from the cloud.

Task 4.1 Compare AWS pricing models

You have set up a multi-tier application on AWS, which uses services spread across the us-east-1 (N. Virginia) and us-west-2 (Oregon) Regions. To help keep costs under control, you have configured AWS Budgets to alert you when your estimated charges exceed your budgeted amount. Your application recently began to see increased traffic, which led to a rise in data transfer between regions.
