Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What Azure service can help in monitoring application performance?

1. Azure Monitor

2. Application Insights

3. Azure Service Health

4. Azure Security Center

The correct answer is: Application Insights

Application Insights is a service specifically designed to monitor application performance. It provides real-time monitoring capabilities, which include tracking the availability, performance, and usage of your applications. This service helps developers and IT professionals gain insights into their applications by detecting anomalous behavior, diagnosing issues, and understanding how users interact with the application. By utilizing Application Insights, you can collect telemetry data, such as request rates, response times, and failure rates, which can be crucial for performance tuning and improving user experiences. It integrates easily with various frameworks and languages, making it a versatile choice for diverse application environments. Azure Monitor is also an important service for monitoring. While it does encompass a broader range of monitoring functions, including infrastructure and network monitoring, Application Insights is specifically tailored for application performance, making it more optimal for that particular use case. Azure Service Health focuses on the health of Azure services and resources, informing users about service incidents, issues, and planned maintenance, but it does not provide application performance monitoring. Azure Security Center, on the other hand, is aimed at security posture management and threat protection but does not address application performance metrics. In summary, Application Insights stands out as the most appropriate service for monitoring application performance, with specialized tools and capabilities tailored for that purpose
