You have an Exchange Server 2010 organization. The organization is authoritative for the domain contoso.com.
You create a federated trust.
You need to ensure that federated partners can automatically locate the Client Access servers in the organization.
What should you create from an external DNS server?
A.
an A record for autodiscover.contoso.com.
B.
an A record for FederatedSharing.contoso.com.
C.
an SRV record for _autodiscover._TCP._msdcs.contoso.com.
D.
an SRV record for _FederatedSharing._UDP._msdcs.contoso.com.
Explanation:
As mentioned in another question, this should actually be a CNAME record, according to Technet, but I left this in here as an A record for contoso.com would need creating before the CNAME for autodiscover.contoso.com. The exam will only mention CNAME records though.Reference:
