Exam AZ-204 topic 5 question 16 discussion

Based on the doc, I believe B is correct. https://docs.microsoft.com/en-us/azure/azure-monitor/app/availability-azure-functions

I think the answer should be URL Ping Test. It can send an alert when the website is unavailable or unresponsive. See test timeouts and alerts in the link. https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability

From Chatgpt: You need to monitor availability and responsiveness of REST API endpoints — this is exactly what URL ping tests in Application Insights are designed for. URL Ping Test Features: Periodically sends requests to your endpoints (e.g., every 5 minutes) Monitors availability, response time, and dependent resource load Allows custom success criteria (e.g., response code, time threshold) Retries automatically before reporting a failure Can trigger alerts via Azure Monitor

It should be URL ping test

The URL Ping will only log the response time if the timeout is reached. To always monitor it, the trackavailability method shall be used. It's nuanced, but I think this is the differentiator.

Based on the information, creating a timer triggered function that calls TrackAvailability() and sends the results to Application Insights is the best option for monitoring the availability and responsiveness of the functions.

It has to be C - The URL ping test uses advanced HTTP request functionality to validate whether an endpoint is responding. They measure the performance associated with that response. They also add the ability to set custom success criteria, coupled with more advanced features like parsing dependent requests and allowing for retries. https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability#actions-if-you-see-failures

Adding a new diagnostic setting (Option D) can enable logging for the Azure Function app, but it will not provide the ability to monitor the availability and responsiveness of the REST API endpoints or generate an alert when they are unavailable or responding too slowly.

Creating a timer triggered function (Option B or C) can also be used to call the REST API endpoints and report the results to Application Insights. However, this approach requires additional development effort and maintenance overhead, which is not necessary for this scenario. Moreover, it will not provide an immediate alert when the function endpoints are unavailable or responding too slowly.

the best option is to create a URL ping test to monitor the availability and responsiveness of the REST API endpoints. This can be easily configured in Azure Application Insights with minimal effort and can provide immediate alerts when the endpoints are unavailable or responding too slowly.

its B........

B is correct

A - Because the URL ping test automatically measures availability and response times.

B is correct answer. https://docs.microsoft.com/en-us/azure/azure-monitor/app/availability-azure-functions

"You need to monitor the availability and responsiveness of the functions." You want it to be on application insights

"You need to monitor the availability and responsiveness of the functions." You want it to be on application insights

I would go with A - URL Ping satisfy all the requirements. It does not check SSL validity BUT there is no requirement to do so, buddies https://docs.microsoft.com/en-us/azure/azure-monitor/app/availability-standard-tests
