You have an Exchange Server 2010 organization. You plan to enable Federated Sharing.
You need to create a DNS record to store the Application Identifier (AppID) of the domain for
the federated trust.
Which type of record should you create?
A.
A
B.
CNAME
C.
SRV
D.
TXT
application identifier (AppID)
A unique number generated by the Microsoft Federation Gateway to identify Exchange organizations. The AppID is generated when you create a federation trust with the Microsoft Federation Gateway.
Microsoft Exchange Server 2010 uses Federation for federated delegation. Federation requires a federation trust with the Microsoft Federation Gateway. After you create the trust, you must configure the federated organization identifier with any accepted domains you want to federate.
To provide proof of ownership of the registered Internet domain, you must create a text (TXT) record in the Domain Name System (DNS) zone of each accepted domain you want to federate. The TXT record contains the federated domain proof encryption string generated when you run the Get-FederatedDomainProof cmdlet for each domain.
