Question 57

Correct answer: D

A. AWS CloudFormation is a service that allows you to create and manage AWS infrastructure as code. While it is essential for provisioning resources in a repeatable and automated manner, it is not specifically designed to help identify the root cause of performance issues in real-time.

B. Amazon Inspector is a security assessment service that helps improve the security and compliance of applications deployed on AWS. While it can help identify security vulnerabilities and compliance issues, it may not be the best choice for identifying the root cause of intermittent performance issues on an e-commerce website during peak hours.

C. Amazon CloudWatch is a monitoring service that provides data and insights into your AWS resources and applications. While it can help monitor performance metrics and set alarms based on thresholds, it may not provide detailed insights into the root cause of intermittent performance issues during peak hours.

D. AWS X-Ray is a service that helps developers analyze and debug distributed applications, including those built using microservices architecture. It can provide end-to-end visibility into requests as they travel through your application, making it a suitable choice for identifying the root cause of intermittent performance issues during peak hours.
