Actual exam question from Microsoft's MS-100

Question #: 64
Topic #: 2

HOTSPOT -
You have a Microsoft 365 subscription linked to an Azure Active Directory (Azure AD) tenant named contoso.onmicrosoft.com.
In the subscription, an administrator adds two custom domains named sub1.contoso.onmicrosoft.com and sub2.contoso.onmicrosoft.com and the objects shown in the following table.

You plan to delete sub1.contoso.onmicrosoft.com and sub2.contoso.onmicrosoft.com.
Which objects must you delete or modify manually before you can delete the domains? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Show Suggested Answer

Suggested Answer:

Anything with an email address in the subdomain needs to be removed or moved to another domain. This includes users, mail-enabled security groups, distribution groups and contacts. Office 365 groups will also need to be removed from the subdomains (they cannot be moved to another domain). However, the only Office 365 group in this question is in the parent domain, not the subdomains.

As usernames revert automatically, but email addresses do not, shouldn't the answer be: Sub1: Group1 only Sub2: Contact2 and Group2 only

Totally agree. You can't delete a domain with any resources still assigned to that domain. Even if using PS and using a -Force the operation will fail. So, yes; Sub1: User1 and Group1 Sub2: Contact2 and Group2

Why Group 3? It doesn't belong to either of the subdomains. If it mattered, it would have to be in both answers! Nope! 1: User 1 and Group 1 2: Contact 2 and Group 2

For Sub1, you need to delete User1 & Group1 For Sub2, you need to delete only Group2, you don't need to delete the contact, this is not a resource in the tenant, is a contact as its name says, so all users within the tenant can see the organization contacts https://learn.microsoft.com/en-us/azure/active-directory/enterprise-users/domains-manage#delete-a-custom-domain-name

Before you can delete the custom domains sub1.contoso.onmicrosoft.com and sub2.contoso.onmicrosoft.com, you must delete or modify the following objects: For sub1.contoso.onmicrosoft.com: Group1: Delete the distribution group or change its email address. user1: Modify the user's username to use a different domain. For sub2.contoso.onmicrosoft.com: Group2: Delete the mail-enabled security group or change its email address. contact2: Delete the contact or change its email address.

Thank you all for confirming what I was thinking. Makes no sense as Group 3 has nothing to do with what they are asking for.

Sooooooo here is the deal. If you use admin panel you can remove domain that still has users assigned (provided you can fall back to something). So technically you don't HAVE TO change any user/group/contact manually. If you use PS, than yes, it will error out and you need to change objects manually (switch -force doesn't force anything. It responds "yes" to confirmation dialog). Assuming M$ want's you to find what will be afected the answeer provided seems correct.

The question has no sense beacuse is not possible to delete a subdomain of onmicrosoft.com after creation. You can add at most 5 onmicrosoft.com subdomains, but you cannot remove them later even if no objects are linked to them - test it!

I don't know what you have actually tested, because I CANNOT delete my sub.mytestdomain.onmicrosoft.com after creation, as official MS doc states: You can't remove your onmicrosoft domain. Microsoft 365 needs to keep it around because it's used behind the scenes for your subscription. But you don't have to use the domain yourself after you've added a custom domain. If you choose to create a new onmicrosoft.com domain, it cannot be removed. You are limited to five onmicrosoft.com domains in your Microsoft 365 environment, so make sure to check for spelling and to assess your need if you choose to create a new one. https://docs.microsoft.com/en-us/microsoft-365/admin/setup/domains-faq?view=o365-worldwide

Not all o onmicrosoft.com are its subdomains. You cannadd new root onmicrosoft.com domain which can't be deleted without suport ticket and subdomain which can be deleted if three are no identity using it in their names or UPNs.

I genuinely believe some of these questions are wrong on purpose because they don't want people getting 100% on these tests. There is absolutely no way the parent domain matters, at all. I thought contacts might, but tell me where in this MS document does it mention changing/deleting contacts? https://docs.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/remove-a-domain?view=o365-worldwide

Sub1: User1 & Group1 Sub2: Contact2 & Group2 Even though contact can exist without domain, we need to think from working scenario point of view. If Contact2 is not deleted/modified then mail sent to contact2 will result in delivery failure

But the question is explicitly asking, "Which objects must you delete or modify manually before you can delete the domains?" It isn't asking about anything other than what is absolutely required to remove the sub domains. Since your answer indicates that a contact can survive without a domain, the answer would suggest that we don't NEED to delete the contact.

Meant to say we don't NEED to delete or modify the contact.

Another one where we have to guess a bit what they want and is a bit ambigous (too common unfortunately) I would probably go for : Sub1: User 1 and Group1 only Sub2: Group2 only Even though I agree that user1 would automatically revert anyway, I am working on the assumption that they are looking for you to choose the objects that will be impacted. A contact can have any domain and it doesnt in fact even check to see if it is a valid domain when you create them (try it by adding a contact with a made up domain, sub domain, sub domain of your tenants onmicrosoft.com - all work without error)

Contacts do not need to be deleted as their external to your tenant. I agree with davem90

I also agree with davem90 and FumerLaMoquette as contacts can be for external users, as such if Group2 has it's UPN suffix changed then there should be no errors raised when the domain is removed from 365. I have had tenants before where I have removed the domain despite having a contact present with the domain name (Used for testing) and there were no issues.

Based on the following link https://docs.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/remove-a-domain?view=o365-worldwide The answer should be: A: - User1 - Group1 B: Group2 In the article there is nothing related to contact

Correct - you don't need a verified domain to add exchange contacts (as they'll mostly be external domains)

I think nothing is neccesarry to be deleted before deleting domain. Also, I think that would be too easy question - you can actually check for each entity which domain it belongs to and solve question that way. That's why I would go with NO resources MUST be deleted or modified
