Exam MS-100 topic 2 question 16 discussion

Answer: C Explanation The question states that only five of the synchronized users have usernames that use a UPN suffix of onmicrosoft.com. Therefore the other 45 users have the correct UPN suffix. This tells us that the adatum.com domain has already been added to Office 365 as a custom domain.The forest is named adatum.local and uses adatum.com as a UPN suffix. User accounts in the domain will have adatum.local as their default UPN suffix. To use adatum.com as the UPN suffix, each user account will need to be configured to use adatum.com as the UPN suffix. Any synchronized user account that has adatum.local as a UPN suffix will be configured to use a UPN suffix of onmicrosoft.com because adatum.local cannot be added to Office 365 as a custom domain. Therefore, the reason that the five synchronized users have usernames with a UPN suffix of onmicrosoft.com is because their accounts were not configured to use the UPN suffix of contoso.com.

Correct Answer is C.

From Active Directory Users and Computers, modify the UPN suffix of the five user accounts.

Can't change the user in the cloud in a hybrid environment. Needs to be changed in AD to begin with and the reason they have the default MS UPN is because their UPN is set to domain.local.

Correct answer is C

Still a valid question as of July 30th 2022.

C correct answer

in today's exam too. seems like whatever Ash473 encountered, i oso have.

In today's exam

"The forest contains 500 users and uses adatum.com as a UPN suffix" If users are synchronised to Azure AD and they don't have a custom domain name in their UPN, this means either a) the custom domain has not been set in Azure AND/OR b) the UPN suffix is incorrect on-premise. Seeing as the question is saying that five of the accounts are affected only, we can only assume the other 45 accounts have the correct UPNs with @adatum.com. Agreed that the wording of the question is confusing but C IS THE ONLY CORRECT ANSWER based on the above.

Team 'C', why you may ask: For instance you have 2 domains on-prem "adatum.de" and "adatum.com", only 1 of those domains is actually added as a custom domain in o365 (the "adatum.com" one). If you create any accounts on-prem with a UPN containing "adatum.com" they will replicate the UPN to o365 (when AAD has been setup). With any accounts created On-prem containing the "adatum.de" domain they will turn to "adatum.onmicrosoft.com" as the domain is unknown. Thus you should modify the UPN on-prem to achieve this goal

should this not be A? We kind of need to address the adatum.local issue before we do anything else right? we should make it adatum.com if available so that it can be routable on the inter webs? I think those 5 users were the distraction to sie fundamentals

ignore above - there is no suggestion in the question that the remaining 450 users are to be synced - so from the wording you can only focus on the 5 - C.

this is a staged migration. The question tells you to make sure ALL users retain the on-prem address. So it is wrong to focus on the 5 incorrect ones in the current batch. You are told to stop this problem occurring for ALL users. A.

C for sure!

The question say "The forest contains 500 users and uses adatum.com as a UPN suffix." And the question mentioned only 5 users accounts, not mention anything for the rest of accounts. Then I go for 'A', no change at on-premise, but change setting on Azure AD.

correct
