Exam AZ-204 topic 5 question 15 discussion

IMO, B is correct, a URL ping test is enough.

The Given Answer D is correct. Ping URL, does not satisfies : Verify that the websites respond within a specified time threshold. Dependent requests such as images and JavaScript files must load properly

D: Create a multi-step web test to query the home page.

Multi-step web tests is retired: https://azure.microsoft.com/en-us/updates/retirement-notice-transition-to-custom-availability-tests-in-application-insights/

Because of "Dependent requests such as images and JavaScript files must load properly."

Every solution could be fine, but URL Ping Test requires the least amount of effort.

From the documentation: The name URL ping test is a bit of a misnomer. These tests don't use the Internet Control Message Protocol (ICMP) to check your site's availability. Instead, they use more 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.

In URL-Ping test it's possible to set dependent requests, retries, etc...

It looks like its B though: https://learn.microsoft.com/en-us/previous-versions/azure/azure-monitor/app/monitor-web-app-availability

if the answer is D. Create a multi-step web test to query the home page., then it's actually E. from Msoft site: We recommend using TrackAvailability to submit custom availability tests instead of multistep web tests. This option is the long-term supported solution for multi-request or authentication test scenarios. With TrackAvailability() and custom availability tests, you can run tests on any compute you want and use C# to easily author new tests. hmm

Ping test seems to be the least effort solution

Answer B as it satisfies all requirements.Below is the reason for URL ping test. The Azure App Service has built-in URL ping testing that can be configured to check whether a website is responsive every five minutes, and generate alerts if there are issues. The URL ping test can also check that the website responds within a specified time threshold and that dependent requests such as images and JavaScript files load properly. Additionally, the URL ping test will automatically retry up to three times if the website fails to load.

B is correct because: 1. The test requests images, scripts, style files, and other files that are part of the webpage under test. The recorded response time includes the time taken to get these files. The test fails if any of these resources can't be successfully downloaded within the timeout for the whole test. If the option isn't enabled, the test only requests the file at the URL that you specified. Enabling this option results in a stricter check. The test might fail for cases that aren't noticeable from manually browsing through the site. 2. When the test fails, it's retried after a short interval. A failure is reported only if three successive attempts fail. Subsequent tests are then performed at the usual test frequency. Retry is temporarily suspended until the next success. This rule is applied independently at each test location. We recommend this option. On average, about 80 percent of failures disappear on retry. https://learn.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability

B. Set up a URL ping test to query the home page.

https://docs.microsoft.com/en-us/azure/azure-monitor/app/monitor-web-app-availability Test timeout - Decrease this value to be alerted about slow responses. The test is counted as a failure if the responses from your site haven't been received within this period. If you selected Parse dependent requests, all the images, style files, scripts, and other dependent resources must have been received within this period.
