You have been asked to provide some advice to Fabrikam, a small manufacturing business that migrated to Microsoft 365. Fabrikam needs your advice because the person responsible for Fabrikam's IT recently left the company. During the process, they handed over the credentials of all their Microsoft 365 accounts to the CEO.

The CEO also reports to you that there have been license problems. The company initially purchased a 50-license subscription. Since then, 10 new users have been employed to replace 10 people who left the company over the last few months. The employees who departed still have Microsoft 365 accounts.

Fabrikam has signed up for a Microsoft 365 subscription and is currently using the tenant name Fabrikam.onmicrosoft.com. Fabrikam wants to assign their custom domain, Fabrikam.com, to Microsoft 365 and to have Microsoft DNS servers host this zone. With this information in mind, answer the following questions:

What kind of DNS record must be added to confirm ownership of the Fabrikam.com DNS zone?

Which DNS records must be modified to have Microsoft DNS servers host the Fabrikam.com DNS zone?

Describe the nature of at least one user account that will have global administrator rights for Fabrikam's Office 365 subscription.

What methods can be used to resolve the license conflicts?
