Exam MS-720 topic 3 question 13 discussion

DRAG DROP -
You have a Microsoft Teams Phone deployment.
When you attempt to deploy a Session Border Controller (SBC) named sbc1.contoso.com, you receive the following error message: "We can't use the
"SBC1.contoso.com" domain as it hasn't been set up in the organization. Try again. If you continue to have problems, contact Microsoft customer support."
You need to add the SBC to the tenant.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:

Suggested Answer:
Step 1: From Microsoft 365 admin center, add and validate the contoso.com domain
Add a base domain to the tenant and verify it.
1. In the Microsoft 365 admin center, go to Setup > Domains > Add domain.
2. In the Enter a domain you own box, type the FQDN of the base domain. In the following example, the base domain is customers.adatum.biz.
3. Click Next.
4. If you add an FQDN that has not been verified before, you'll need to go through the process of verification.
5. Etc.
Step 2: From Microsoft 365 admin center, add a licensed user that has a UPN to the contoso.com domain.
Activate the domain name.
After you have registered a domain name, you need to activate it by adding at least one user with a Phone System license and assigning a SIP address with the
FQDN portion of the SIP address matching the created base domain.
Step 3: From Microsoft 365 admin center, add the SBC as sbc1.contoso.com
Add the FQDNs for the SBC. In this case sbc1.contoso.com.
