An organization implements Call Admission Control for Lync to control bandwidth usage and assure a high quality experience. Users in the Portland office frequently use Lync Enterprise telephony and conferencing features offered from the Lync infrastructure in the Chicago site. An administrator is determining which type of audio and video codecs will optimize bandwidth utilization on a per- session basis. The administrator needs to prevent media that is traversing the network connection between Portland and Chicago from using the G.711 codec without impacting the ability to use the RTAudio wideband codec. Which action meets these requirements?

• A.Change the Audio Session Limit in the bandwidth policy for the Portland site to 105 kbps.
• B.Change the Audio Session Limit in the bandwidth policy for the Portland site to 50 kbps.
• C.Change the Audio Session Limit in the bandwidth policy for the Portland site to 106 kbps.
• D.Change the Audio Session Limit in the bandwidth policy for the Portland site to 100 kbps

Contoso deployed Lytic Front End pools in Redmond and in London. The Redmond pool services 15,000 users and the London pool services 5,000 users. All users should be enabled for Instant Messaging and Conferencing. How should an administrator design the conferencing server topology to meet conferencing requirements and comply with Microsoft recommendations?

• A.Deploy A/V Conferencing pools in Redmond and London.
• B.Configure the London and Redmond pools to use the built in conferencing capabilities of the Front End Servers.
• C.Deploy an A/V Conferencing pool in Redmond. Configure the Front End pools in Redmond and London to use this A/V Conferencing pool.
• D.Deploy an A/V Conferencing pool in Redmond. Configure the London pool to use the built in conferencing capabilities of the Front End Servers.

An organization is deploying Microsoft Lync Server 2010 and needs to identify the numbering plan that will require the smallest amount of change to the legacy PBX environment. The legacy PBX:
Supports 4 digit extension dialing with extensions in the following ranges 4000-5999.
Has been configured to send calls in the range of 6000-7999 to be routed to the Lync Mediation server.
Normalization rules have been added to Lync to convert all inbound calls to E.
164 format
Which approach will allow 4 digit dialing between Lync and the legacy PBX?

• A.Assign Lync users a LineURI in the range of+6000 to +7999. Configure the
  digit manipulation on the Legacy PBX to strip all but the last 4 digits on inbound
  calls from the Lync server.
• B.Assign Lync users a LineURI in the range of+6000 to +7999. Create a Trunk
  Configuration translation rule to send only the last 4 digits to the legacy PBX.
• C.Assign Lync users a LineURI in the range of+14255556000 to +14255557999.
  Configure the digit manipulation on the Legacy PBX to strip all but the last 4
  digits on inbound calls from the Lync server.
• D.Assign Lync users a LineURI in the range of+14255556000 to
  +14255557999. Create a Trunk
  Configuration translation rule to send only the last 4 digits to the legacy PBX.

An organization deployed a Microsoft Lync Server in its primary datacenter.
Many users work in branch offices and currently register to the FrontEnd Pool in the primary datacenter.
Branch office requirements:
Support 1200 users with heavy telephony and conferencing usage.
Minimize the impact on the branch office through poorly performing WAN connectivity.
Keep the costs as low as possible. Which option meets these requirements?

• A.Deploy a Standard Edition Server with a collocated Mediation server and a separate PSTN gateway. Configure calls to and from the PSTN to use local PRIs.
• B.Deploy a Survivable Branch Appliance with a collocated PSTN gateway. Configure calls to and from the PSTN to use local PRIs.
• C.Deploy a Survivable Branch server with a separate PSTN gateway. Configure calls to and from the PSTN to use local PRIs.
• D.Deploy a Survivable Branch server with a collocated Mediation server and a separate PSTN gateway. Configure calls to and from the PSTN to use local PRIs.

A customer plans to deploy Microsoft Lync Server 2010 for all workloads including instant messaging and presence, video and web conferencing, and enterprise voice. The customer needs to determine an appropriate server topology design for this deployment. The requirements from the customer are:
Assume standard user model usage.
Topology must support 20,000 users.
High availability is required within a single data center location for all workloads. Which topology should an administrator recommend?

• A.Two Enterprise Edition pools, each with a FrontEnd server. Each pool configured as the backup registrar for the other pool.
• B.Enterprise Edition pool with two FrontEnd servers. Standard Edition server configured as the backup registrar for the Enterprise Edition pool.
• C.Enterprise Edition pool with two FrontEnd servers. A/V Conferencing pool with two A/V Conferencing servers.
• D.Four Standard Edition servers; each server configured to have one backup registrar. A/V Conferencing pool with two A/V Conferencing servers.)
