AAD tenants

Hi all,

In the AZ-900 course (chapter 8 – "AAD") it says:

"One User – One Tenant – each user in Azure can only belong to a single tenant. Users can be guests of other tenants though"

However, in the quiz, that is connected to this chapter, there is a question about this:
"How many tenants can a single user belong to in Azure Active Directory?"

And the correct answer is "500".

Also, the official MS Azure doc says that a single user can belong to a maximum of 500 Azure AD tenants as a member or a guest.

https://docs.microsoft.com/en-us/azure/active-directory/enterprise-users/directory-service-limits-restrictions

Would be good to correct this chapter (of course if my understanding is correct :)).
