C) Configure the gateway as trusted server with Lync.
D) Add gateway as a contact object in Active Directory.
E) Configure a static route to the gateway in Lync.

4. Refer to the exhibits.

Contoso has a Lync infrastructure deployed. At the central site, Lync is integrated with an existing EP-PBX via Direct SIP. At the branch site, a SBA is deployed. There is a 2mbps link between the central and a branch site. During good network conditions, with no call admission control policies in place, there is a call from a user at the branch site to an IP-PBX user in the central site. According to the table, what is the maximum bandwidth in kbps that will be used?

A) 61.6
B) 49.8
C) 102
D) 166

5. Contoso is deploying Lync 2010 Enterprise
Voice with Exchange 2010 SP1 Unified Messaging (UM). A consultant has configured Exchange UM as follows: Exchange UM Dial Plan: Redmond Subscriber Access Number: +14255551000 Exchange UM Auto Attendant: Name: Corp AA Associated Dial Plan: Redmond Pilot Identifier: 9999 During the deployment, a few users indicate that they are unable to dial the Exchange Auto Attendant from the Lync client. Logging
shows the error: "The application specified an invalid request-un". What will correct this problem?

A) Change the Exchange UM Dial Plan VoIP Security setting to Secured.
