Common exam traps

Where candidates lose marks on Monitor, troubleshoot, and optimize Azure solutions

⚠Selecting the most expensive service when a simpler managed option meets the requirement.
⚠Forgetting that cloud resources must be explicitly secured — defaults are rarely secure.
⚠Choosing a global service fix when the issue is region-specific.
⚠Overlooking cost implications of cross-region data transfer in architecture questions.

An Azure web app is experiencing high memory usage. You want to collect memory dumps periodically to analyze the issue without restarting the app. Which Azure App Service diagnostic feature should you use?

An application uses Azure Application Insights for monitoring. You need to write a query to analyze the number of failed requests and exceptions over the past hour. Which query language should you use?

Your web app hosted on Azure App Service is experiencing high memory usage. You need to capture a memory dump for analysis without restarting the app. Which diagnostic feature should you use?

You need to monitor the performance of an Azure web app. You want to track the average response time and the number of failed requests over the last hour. Which Azure service should you use?

You are troubleshooting an Azure Function that intermittently throws exceptions. You have enabled Application Insights. You need to capture the exact line of code that caused the exception, even for exceptions that occur during high load. Which feature should you use?

You are monitoring an Azure Web App with Application Insights. You notice that certain requests have high server response times. You need to identify which specific database queries are causing the delays. Which Application Insights feature should you use?

Your Azure web app is running in a production environment. Users report that the app is slow. You need to identify the root cause without impacting production traffic. Which approach should you use?

You are using Application Insights to monitor a web app. You want to automatically analyze and alert on sudden increases in request failure rates, without manually setting static thresholds. Which Application Insights feature should you use?

You are monitoring an Azure Function app that processes messages from an Event Hub. You want to be alerted if the function is failing to process messages (e.g., exceptions) and automatically restart the function host. Which Azure service should you use?
