Explanation:
Box 1: Set-CsMeetingConfiguration
Box 2: Set-CsClientVersionPolicy
Box 3: Set-CsExternalAccessPolicy
Note:
* Set-CsMeetingConfiguration enables you to modify the meeting configuration settings
currently in use in your organization. Meeting configuration settings help dictate the type of
meetings (also called conferences) that users can create, and also control how (or even if)
anonymous users and dial-in conferencing users can join these meetings. Note that these settings
only affect scheduled meetings; they do not affect ad-hoc meetings created by clicking the Meet
Now option in Microsoft Lync.
* Set-CsClienetVersionPolicy
Modifies an existing client version policy. Client version policies enable you to specify which
clients (such as Microsoft Office Communicator 2007 R2) will be allowed to log on to your Lync
Server system.
* Set-CsExternalAccessPolicy
Enables you to modify the properties of an existing external access policy. External access

policies determine whether or not your users can: 1) communicate with users who have Session
Initiation Protocol (SIP) accounts with a federated organization; 2) communicate with users who
have SIP accounts with a public instant messaging (IM) provider such as MSN; and, 3) access
Lync Server over the Internet, without having to log on to your internal network.
* Incorrect: Set-CsConferencingPolicy
Modifies an existing conferencing policy. Conferencing policies determine the features and
capabilities that can be used in a conference; this includes everything from whether or not the
conference can include IP audio and video to the maximum number of people who can attend a
meeting.
*Incorrect: Set-CsConferencingConfiguration
Modifies an existing collection of conferencing configuration settings. Conference settings
determine such things as the maximum allowed size for meeting content and handouts; the
content grace period (that is, the amount of time content will be stored before being deleted); and
the URLs for the internal and external downloads of the supported client.
