3. Question
Category: CSAP – Continuous Improvement for Existing SolutionsA car parts manufacturing company installed IP cameras along its assembly line. These cameras are part of the quality inspection as they take photos of each car part and find defects by comparing them with a baseline image. To improve the accuracy of detection, the company used Amazon SageMaker to train a machine learning (ML) model that contains baseline images and common defects.
Upon detection, the workers should receive feedback from the Linux server in the on-premises data center that hosts an API for the IP cameras. The company wants to make this solution available even when the factory’s internet connectivity is down.
Which of the following options is the recommended solution for deploying the ML model that meets the company’s requirements?

Question 8 of 15
8. Question
Category: CSAP – Continuous Improvement for Existing SolutionsA company has released a new mobile game and its backend servers are hosted on the company’s on-premises data center. The game logic is exposed using REST APIs that have multiple functions depending on the user state. Access to the backend services is controlled with an API key, while any test traffic is distinguished by a different key. A central file server stores player session data. User traffic is variable throughout the day but the on-premises servers cannot handle traffic during peak hours. The game also has latency issues caused by the slow fetching of player session data. The management tasked the solutions architect to migrate this infrastructure to AWS in order to improve scalability and reduce the latency for data access while keeping the backend API model unchanged.
Which of the following is the recommended solution to meet the company requirements?
CorrectIncorrect -
