Which two cmdlets should you run?

Your company has an Exchange Server 2013 organization named Contoso.
A partner company has an Exchange Server 2013 organization named Fabrikam. Neither company
has any trusts between their forests.
Users from both organizations access their mailbox from the Internet by using Outlook Anywhere.
You need to ensure that the users from both organizations can share free/busy information.

Which two cmdlets should you run? (Each correct answer presents part of the solution. Choose two.)

A.
New-AcceptedDomain

B.
Add-AvailabilityAddressSpace

C.
Set-AvailabilityConfig

D.
New-SharingPolicy

E.
Add-ADPermission

Explanation:
B: Use the Add-AvailabilityAddressSpace cmdlet to define the access method and associated
credentials used to exchange free/busy data across forests.

organization can share calendar and contact information with users outside the organization. Users
can only share this information after federation has been configured in Exchange.
