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

Which Azure service is designed to monitor and diagnose issues in applications deployed on the Azure platform?

1. Azure Monitor

2. Application Insights

3. Azure Advisor

4. Resource Health

The correct answer is: Application Insights

The Azure service that is specifically designed to monitor and diagnose issues in applications deployed on the Azure platform is Application Insights. This service is part of Azure Monitor and provides deep insights into application performance and user behavior. It allows developers to track application availability, performance metrics, and exceptions. This helps pinpoint the root cause of any issues so that they can be resolved effectively, enhancing the overall user experience. Application Insights also offers powerful analytics capabilities, including the ability to analyze logs, detect anomalies, and track the performance of various components of your application. By providing this level of detail, it supports proactive troubleshooting and performance optimization, making it an essential tool for developers managing applications in Azure. In contrast, Azure Monitor is a broader service that aggregates data and provides insights across all Azure resources, while Azure Advisor offers recommendations for optimizing Azure deployments based on best practices. Resource Health focuses on the status of Azure services and resources but does not specifically diagnose application issues. Thus, Application Insights is the most appropriate choice for monitoring and diagnosing application-specific issues.
