Microsoft 365 Administrator Expert MS-102 Practice Question

Contoso Ltd. hosts contoso.com with a third-party DNS provider and currently routes all email through an on-premises mail system. You are adding contoso.com to a Microsoft 365 tenant but must guarantee that production mail flow will be unaffected during the verification phase. Which change should you make in the external DNS zone before you finish the domain setup wizard?

  • Change the domain's authoritative NS records to Microsoft 365 nameservers.

  • Replace the current MX record with the Microsoft 365 MX endpoint assigned to the tenant.

  • Add a TXT record that contains the unique verification value supplied by Microsoft 365.

  • Create a CNAME record for autodiscover that points to autodiscover.outlook.com.
