Microsoft AB-900 Exam - Topic 1 Question 6 Discussion

Posted by Carma on Apr 01, 2026 at 07:20 AM

Your organization has a Microsoft 365 subscription.

Which two tasks can you perform by using the Exchange admin center? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Suggested Answer: A, D

The correct answers are A and D because both tasks are supported directly in the Exchange admin center (EAC). Microsoft Learn states that administrators can manage mail flow rules in Exchange Online from the EAC under Mail flow > Rules, which includes creating and managing transport rules for organizational email handling. Microsoft Learn also states that administrators can create shared mailboxes in the EAC under Recipients > Mailboxes, where a shared mailbox can be added and then delegated to users.

Option B is incorrect because adding a custom domain is normally done in the Microsoft 365 admin center, specifically on the Domains page. Although Exchange can later work with accepted domains and related mail flow settings, the act of adding and verifying a custom domain is not an Exchange admin center task. Option C is incorrect because license assignment is handled through Microsoft 365 or Microsoft Entra administrative tools, not the Exchange admin center.

I feel like B could also be right. Adding a custom domain is important too.

I thought you could assign licenses in Exchange too, but I guess not!

B is not right, you do that in the Microsoft 365 admin center, not Exchange.

Wait, can you really add a custom domain through the Exchange admin center?

I know for sure that creating a shared mailbox is an option in the Exchange admin center; I practiced that in a lab scenario!

I feel like assigning a Microsoft Exchange license might be done in a different part of Microsoft 365, not specifically in the Exchange admin center.

I remember practicing with adding a custom domain, but I can't recall if that was in the Exchange admin center or somewhere else.

I think creating a mail flow rule is definitely something we can do in the Exchange admin center, but I'm not sure about the second option.
