First box: Mobile https://docs.microsoft.com/en-us/python/api/azure-mgmt-cdn/azure.mgmt.cdn.models.isdevicematchconditionparametersmatchvaluesitem Third box: iPhone. We are not looking for other Apple devices running iOS. It's the iPhone we're looking for.

You are right, also the HTTP_USER_AGENT can be iPhone, iPad, etc... There isn't iOS. Even because iPhone and iPad I believe both could have iOS running in it.

1 DeliveryRuleDeviceConditionParameters - we are first checking for a device condition, hence we need to use the condition of DeliveryRuleDeviceConditionParameters 2.Mobile - The devices can be either Desktop or Mobile. These are the two accepted values. Here since we need to route requests based on mobile devices, we need to choose the value of Mobile. 3.DeliveryRequestHeaderConditionParameters. we need to understand the type of operating system running on the device. We can get this information from the request headers. Hence, we need to use the parameter of DeliveryRequestHeaderConditionParameters. 4.HTTP_USER_AGENT - we can check the HTTP_USER_AGENT property in the request header. In the user agent property of the request header, you will normally get information about the environment where the request is originating from. An example is given below where I am showing the request header from my own machine when I browse to a site. 5.iOS - we need to check the operating system which will be iOS.

I agree on the first four points, but the fifth point is incorrect. The correct answer is iPhone. Here you can see lots of iOS User Agent examples: https://developers.whatismybrowser.com/useragents/explore/operating_system_name/ios/ "iPhone" appears all the time and "Mac OS X" is used instead of "iOS" Example: Mozilla/5.0 (iPhone; CPU iPhone OS 9_3_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13E238 Safari/601.1

I got this question on my exam, 2023Dec, go with what I remember was the most voted answer. Score 902, most of the questions were here, slightly different on wording because the Azure Ad <-> Entra Id change. Case was City Power & Light. Good luck! Important tip, you have access to microsoft learn during the exam!

This quote is both misleading and dishonest: "You have access to Microsoft Learn during the exam." Such messages should be deleted by the admins, but there are many similar ones in the forum.

I agree this is insane.. how could they ask us to remember all this specific stuff.. I mean look at this table alone: https://learn.microsoft.com/en-us/dotnet/api/microsoft.azure.management.cdn.models?view=azure-dotnet and that's only a single question.. :(

reference: https://docs.microsoft.com/en-us/azure/cdn/cdn-standard-rules-engine-match-conditions the filter rule for device may only accept the value of mobile and desktop. So mobile/iphone is my vote.
