Nothing was mentioned neither about devices quota in the setting nor the user first time joining .. I would rate this question incomplete.

Answer is correct, because could be A or B, but as says that the other users can join then A doesn't fit, then should be B. There is a isolated user with the issue, so probably he joined more than 20 devices (default setup) and for this reason he can't join news. So, solution it's B.

B is correct

B is correct

there are two questions this one says other users can add here it appears A is correct answer the one below says user could add before https://www.examtopics.com/discussions/microsoft/view/34970-exam-az-104-topic-6-question-10-discussion/ here is appears B is correct

Its stated personal device of user. So 100 client devices are already added. Hence to add additional, the given answer is correct.

Assume one thing: the user's device has been added into Azure AD and can successfully access Azure portal when work in the company at London. He cannot access Azure portal when at home. How to fit this problem? Is my question similar with this question? But this problem is Azure user manager or higher controller set the IP policy that only can access the Azure portal from company Internet IP space.

Could be A or B, damn you MS.

Answer is A because by default users can join 50 machines to Azure AD. The problem is “ Users may join devices to Azure AD” is set to a group which that user is not part of that group.

Answer is B

Seems A and B both can be correct. But what if user gets his Mac or Android tablet and MS doesn't allow it ? or its Widows 7 legacy devise ?

I believe the answer is A. If the question had said the user could not REGISTER their device, then the fact that others could do the action would matter because you can either allow everyone to register or no one. You can't have some being able to register and some not, which would mean that the device limit would naturally be the next logical choice. But in this case, they said JOIN, and you can configure certain users to be able to join devices and others not. So the first thing you'd check is if the user has rights to JOIN devices, and if they do then *maybe* B. The maximum number of devices per user is a universal setting. Before I go and change a setting that affects all users, I would first look to see if this user has an unusually high number of devices and remove some of them. If a lot of my users were nearing 20, then B.

A or B. It could be A if individual users are added to 'Users may join devices' set to 'Selected' and all users except User1 are added, then that's why User1 only can't join their device. So modifying the setting from Selected to All would fix that. It could also be B if they have reached their device quota. It's best guess on this one. I'm going for B - device quota.

Answer is B as if it reaches the maximum number of devices then User will not be able to join device to AD as the questions is.

The current answer should be A

In my opining B is correct. Tricky question: it says "unable to join a personal device" "A remote user named User1 is unable to join a personal device to Azure AD from a home network"

Is this option B just due to the generic statement "You verify that other users can join their devices to Azure AD"? I mean, technically it could be set to specific users and this one user isn't selected. The question also doesn't mention if the user has other devices added already, etc. Just poorly worded? Still, why is it 100% B and not A?
