You have an Azure subscription.
You create an Azure Active Directory (Azure AD) tenant named Tenant1 that has a domain name of
tenant1.onmicrosoft.com. You need to add the contoso.com domain name to Tenant1.
Which DNS record should you add to the contoso.com zone to be able to verify from Azure whether you own
the contoso.com domain?
A.
standard alias (CNAME)
B.
mail exchanger (MX)
C.
host (AAAA)
D.
signature (SIG)
Answer is B (MX)
May seem weird since that would mess up your mail. The smart answer would be TXT. But since that’s not a choice, the answer is MX. TXT and MX are the only ways to verify a Azure AD custom domain. I just checked myself.

Question states the requirement to “verify from Azure whether you own the contoso.com domain”
This can only be done using TXT or MX as mentioned; learn this.
If requirement was to forward requests from contoso.com to Azure, it would be A (CNAME).

Both answers are correct.. CNAME and MX.
