You have an IP-PBX that uses four-digit extensions. You plan to deploy Enterprise Voice. You implement a SIP trunk between the Lync Server infrastructure and the IP-PBX. You configure all users to use the following LineURI: tel:+3120123 <4digitextension>;ext=<4digitextension> You need to ensure that the IP-PBX only receives the four-digit extension of a user when a call is placed to the IP- PBX. What should you do?

You have a Lync Server 2013 infrastructure.
You plan to deploy E911 services.
You configure Lync Server to require that each user has a location.
You configure a location for each subnet. Users report that when they sign in to Microsoft Lync 2013 on the
internal network, they are prompted for their location information. You need to prevent the users from being
prompted for their location information when they sign in to Lync on the internal network. Which cmdlet
should you run?

You are designing the Lync Server 2013 infrastructure. You need to identify the minimum number of Lync Server 2013 Mediation Servers, Lync Server 2013 trunks, and PSTN gateways that must be added to the New York office. The solution must meet the Enterprise Voice requirements. What should you identify? To answer, configure the appropriate number for each component in the answer area.

Ensure that the New York users and the Boston users who have IP-PBX phones can call each other without
using the PSTN.
2 Mediation server matches Enterprise Voice Requirement.
MUST not depend on a single component.
2 lync trunks are to Chicago and Boston
NY already has 2 gateways. No more need to be added.
[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.

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.
You need to recommend which ports must be configured on the hardware load balancer to meet the technical requirements.
Which TCP ports should you include in the recommendation?

You have a Lync Server 2013 infrastructure.
A user named Executive1 has an assistant named Assistant1. Assistant1 is configured as a delegate and
receives all of the calls for Executive1.
You need to modify the current voice solution to meet the following requirements:
-Ensure that some of the calls from other executives to Executive1 only ring on the Microsoft Lync 2013 client of Executive1.
-Ensure that Executive1 can receive the calls from the other executives when his presence status is set to Do Not Disturb.
What should you configure?

You have a Lync Server 2013 infrastructure that contains two offices. The offices are located in Amsterdam and Seattle. The offices have the phone number ranges shown in the following table.
You plan to deploy Enterprise Voice.
You also plan to use a global dial plan that will use three-digit dialing. You need to create the normalization
rules for the planned deployment. Which match patterns should you use to create the normalization rules?
To answer, drag the appropriate match patterns to the correct translation patterns in the answer area. Each
match pattern 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.

TechNet CLEARLY tells, with black letters on white background:
1) A/V EDGE to get involved in CAC-related Subnet definition and 2) YES we DO use 32-bit mask...
so for New York this is 131.107.100.3/32 ...
NO .../24: why include WHOLE subnet where we only need public IP of A/V Edge?
First all, the question is 'for CAC and media bypass'.
Now, from link: http://technet.microsoft.com/en-us/library/gg398585.aspx, we know
####
Media bypass and bandwidth reservation are mutually exclusive. If a media bypass is employed for a call,
call admission control is not performed for that call. The assumption here is that there are no links with
constrained bandwidth involved in the call. If call admission control is used for a particular call that involves
the Mediation Server, that call cannot employ media bypass.
#####
For CAC itself, link: http://technet.microsoft.com/en-us/library/gg398334.aspx. Read bottom of the page, "it
is important that subnets entered during network configuration on the server are actual subnets instead of
virtual subnets". It explained why 192.168.8.0/21, 30.0/23, ..
Now considering A/V edge server, link: http://technet.microsoft.com/en-us/library/gg425827.aspx. It says: If you deploy Audio/Video Edge Servers, the public IP addresses of each Edge Server must be associated with the network site where the Edge Server is deployed. Each public IP address of the A/V Edge Server must be added to your network configuration settings as a subnet with a subnet mask of 32
NY: 131.107.100.0/24 192.168.8.0/21
LA: 192.168.30.0/23
Miami: 192.168.20.0/24
Houston: 192.168.40.0/24
The 192.168.x.x configurations as per defined in scenario.
Then we need a public network address for New York. We must not use the /32 network mask.
