Managing Office 365 Identities and Requirements — Question 9

A company plans to use Office 365 to provide email services for users.
You need to ensure that a custom domain name is used.
What should you do first?

Answer options

• A. Add the custom domain name to Office 365 and then verify it.
• B. Verify the existing domain name.
• C. Create an MX record in DNS.
• D. Create a CNAME record in DNS.

Correct answer: A

Explanation

The correct first step is to add the custom domain name to Office 365 and verify it, as this establishes the domain for use. Verifying an existing domain name (option B) is not applicable since a new domain is being added. Creating an MX record (option C) or a CNAME record (option D) are steps that come after the domain has been successfully added and verified.
