Free Microsoft 70-337 Exam Dumps Questions & Answers

[A40] Your company has a Lync Server 2013 infrastructure that contains four servers. The servers are configured as shown in the following table.

The Lync Server infrastructure contains a hardware load balancer named HLB1. The company has an IPPBX. The IP PBX does not support media bypass. The IP-PBX has a SIP trunk configured. Each user has a desktop phone that connects to the IP-PBX. Each laptop user has a Lync-certified headset. The company plans to implement Enterprise Voice and to relocate the SIP trunks to the Lync Server infrastructure. You need to recommend a Mediation Server deployment to meet the following requirements:
Internal users must be able to place outbound calls from their desktop phone if a single server fails.
Remote users must be able to place calls to any desktop phone if a single server fails.
The degradation of call quality must be minimized during peak usage hours.
What should you recommend?

• A.  Create a Mediation Server pool that contains two new servers.
• B.  Install the Mediation Server role on Server3 and Server4.
• C.  Install the Mediation Server role on Server1 and Server2.
• D.  Create a Mediation Server pool that contains HLB1 and one new server.

You have a Lyric Server 2013 infrastructure. The infrastructure contains one central site. The infrastructure contains a Standard Edition server that has the Mediation Server role installed and is located in the central site.
You configure a trunk to an IP-PBX. The IP-PBX is on the Unified Communications Open Interoperability
program.
You have 300 users who are enabled for Enterprise Voice.
You need to provide PSTN services to the Enterprise Voice users if the IP-PBX fails.
What should you do?

• A.  Install a new trunk to a certified SIP trunk provider. Add the trunk to the existing PSTN usage. Add the PSTN usage to the voice policy.
• B.  Install a Survivable Branch Server that connects directly to the PSTN. Configure a new trunk and add the trunk to the existing route. Add the route to the PSTN usage and add the PSTN usage to the voice policy.
• C.  Install an additional IP-PBX that connects directly to the PSTN. Configure the existing trunk to use both IP-PBXs in resiliency mode.
• D.  Install a PSTN gateway that connects directly to the PSTN. Configure a new trunk to the new PSTN gateway. Create a new route and a new PSTN usage. Add the route to the PSTN usage and add the PSTN usage to the voice policy.

[C10] You need to identify which configurations must be implemented for the planned Lync Server 2013 deployment. The solution must meet the network requirements. Which features should you use? To answer, drag the appropriate features to the correct requirements in the answer area. Each feature may be used once, more than once, or not at all. Additionally, you may need to drag the split bar between panes or scroll to view content.

Correct Answer:

Explanation/Reference: Real-time communications are sensitive to the latency and packet loss that can occur on congested networks. Call admission control (CAC) determines, based on available network bandwidth, whether to allow real-time communications sessions such as voice or video calls to be established. Media bypass is a Lync Server capability that enables an administrator to configure call routing to flow directly between the user endpoint and the public switched telephone network (PSTN) gateway without traversing the Mediation Server. Media bypass improves call quality by reducing latency, unnecessary translation, possibility of packet loss, and the number of potential points of failure. Where a remote site without a Mediation Server is connected to a central site by one or more WAN links with constrained bandwidth, media bypass lowers the bandwidth requirement by enabling media from a client at a remote site to flow directly to its local gateway without first having to flow across the WAN link to a Mediation Server at the central site and back.This reduction in media processing also complements the Mediation Server's ability to control multiple gateways. Differentiated Services code points (DSCPs) mark IP packets with the type of traffic that is contained in each packet. This information is used by QoS to determine the priority of the packet relative to other network traffic. If QoS is enabled on your network, you can take advantage of it by enabling DSCP marking on servers running Microsoft Lync Server and on Lync clients. Because Lync Server and Lync clients require that different media use different port ranges, the Windows or Windows Server operating system can identify the traffic type and apply the appropriate DSCP to each packet according to the port that it uses.

[A20] Users frequently travel between the offices. The company plans to deploy Lync Server 2013 and Enterprise Voice. A pool will be deployed to each office. You need to ensure that if a user dials 911 from any of the offices, the call is routed to the local emergency services provider for that office.
What should you do?

• A.  From the Lync Server 2013, Topology Builder, create one central site. Deploy all pools to the central site. From the Microsoft Lync Server 2013 Control Panel, create a single location policy.
• B.  From the Lync Server 2013, Topology Builder, create one central site. Deploy all pools to the central site. From the Microsoft Lync Server 2013 Control Panel, modify the global location policy.
• C.  From the Lync Server 2013, Topology Builder, create a central site for each office. Deploy one pool to each site. From the Microsoft Lync Server 2013 Control Panel, create a location policy for each location.
• D.  From the Lync Server 2013, Topology Builder, create a central site for each office. Deploy one pool to each site. From the Microsoft Lync Server 2013 Control Panel, create a user-level location policy for each location. Assign the respective user-level location policy to the users in each office.

You are evaluating the use of Microsoft Lync Online and Lync Server 2013. Your company has a sales department, a marketing department, and a research department. Each department gives you a list of required features as shown in the following table.

You need to identify which type of Lync deployment can be used for each department. What should you identify? To answer, select the valid type of Lync deployments for each department in the answer area.
