You have a Lync Server 2013 infrastructure. All client computers have Microsoft Lync 2013 deployed. Monitoring reports show that the client computers are not using media bypass. You run the Get-CsNetworkSubnet cmdlet and you receive the following result:
Identity: 172.16.0.0
MaskBits: 22
Description: New York
NetworkSiteID: New York
SubnetID: 172.16.0.0
Identity: 172.16.4.0
MaskBits: 23
Description: Seattle
NetworkSiteID: Seattle
SubnetID: 172.16.4.0
You need to ensure that all of the client computers use media bypass. What should you do?

A) Delete the existing subnets. Create a single subnet entry for North America that uses a 16-bit mask.
B) Configure the subnet in the New York office and the subnet in the Seattle office to use a 24-bit mask.
C) Delete the existing subnets. Create five subnet entries that each uses a 16-bit mask.
D) Delete the existing subnets. Create five subnet entries that each uses a 24-bit mask.

2. You have a Lync Server 2013 infrastructure and a Microsoft Exchange Server 2010 Service Pack 2 (SP2) organization. All users are enabled for Enterprise Voice and Unified Messaging (UM). Lync Server and Exchange Server are configured to use DTMF only. Your company owns a phone number range of 1

The service will contain a SIP trunk in the Seattle office and a SIP trunk in the Amsterdam office. The solution will use least cost routing. You need to identify the maximum amount of bandwidth that will be used by each SIP trunk. What should you identify?
