You plan to deploy a Microsoft Lync Online subscription that will contain a single SIP domain named contoso.com.
You need to identify which DNS records must be created to meet the following requirements:
-Provide users with the ability to sign in automatically by using Microsoft Lync 2013.
-Provide users with the ability to sign in automatically by using the Lync mobile application.
Which DNS records should you identify? (To answer, select the appropriate record name and destination for each requirement in the answer area.)

[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.

An administrator makes several security changes to the firewalls.
After you deploy Enterprise Voice, remote users report that they fail to access their voice mail by using the
Call Voice Mail option in the Lync client.
You verify that the users can access their voice mail by dialing the subscriber access number.
You need to ensure that the users can access their voice mail by clicking Call Voice Mail.
Which two sets of ports should you open? (Each correct answer presents part of the solution. Choose two.)

• A. TCP 5062 and 8057 on the external firewall
• B. TCP 443 and UDP 3478 on the internal firewall
• C. TCP 5062 and 8057 on the internal firewall
• D. UDP 50,000 to 59,999 on the internal firewall
• E. TCP 443 and UDP 3478 on the external firewall
• F. UDP 50,000 to 59,999 on the external firewall

You need to recommend which Lync Server 2013 solution must be deployed to the New York and Montreal offices to support the planned changes. The solution must meet the business goals.
What should you recommend? (To answer, select the appropriate components for each office in the answer area.)
Hot Area:

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.
Select and Place:

Explanation:
First match pattern: 5 or 7 followed by any two numbers.
Second match pattern: 2 followed by any two numbers.
