You have an Exchange Server 2010 Service Pack 1 (SP1) organization named fabrikam.com. A partner company has an Exchange Server 2010 Service Pack 1 (SP1) organization named contoso.com. You plan to implement federated delegation between fabrikam.com and contoso.com.
You need to identify which DNS records must be created to support federated delegation.
Which DNS records should you identify? (Choose all that apply).
A.
Host (A).
B.
Mail exchanger (MX).
C.
Host information (HINFO).
D.
Text (TXT).
E.
Mail group (MG).
Explanation:
Create a TXT record for federated delegation.
Create an Autodiscover DNS record (CNAME).In this case I left the original A record answer in as that would already need to be created to resolve the IP, then a CNAME record would point to the A record (as CNAMEs can’t point to IP addresses).
