What should you do?

You have a Lync Server 2010 infrastructure.
You plan to migrate to Lync Server 2013.
You have four client computers. The client computers are configured as shown in the following table.

You need to identify which client computer types can use audio conferencing hosted on Lync Server 2013 without installing any additional software on the client
computers.

Which client computer types should you identify? (Each correct answer presents part of the solution. Choose all that apply.)

You are planning a Lync Server 2013 deployment.
You need to recommend which Lync Server 2013 components are required to meet the following requirements:
Presence, chat, and multiparty video conferencing features must be provided.
Quality of Experience (QoE) data and call detail recording (CDR) must be provided.
Lync Server services must be provided to internal users only.
Licensing costs must be minimized.

Which two components should you recommend? (Each correct answer presents part of the solution. Choose two.)

You plan to deploy a Lync Server 2013 infrastructure.
You plan to use a Microsoft SQL Server database mirror that has a witness.
A database administrator gives you a list of five servers that you can use for the deployment. The servers are configured as shown in the following table.

You need to identify which servers you must use for the SQL Server backend.
Which servers should you identify?

You plan to deploy Lync Server 2013.
Your company uses only certificates that are purchased from a third-party certification authority (CA).
The company uses the following domain names to generate email addresses for users:
Adatum.com
Contoso.com
Fabrikam.com
Wingtiptoys.com
You plan to configure simple URLs for the planned deployment.
You need to recommend which meeting URLs to use. The solution must minimize the cost of purchasing certificates.
Which names should you include in the recommendation?

Your company has a main office and a branch office. The main office is located in Amsterdam. The branch office is located in New York. Each office has a data
center. The offices connect to each other by using a high-bandwidth, low-latency WAN link. You have a Lync Server 2013 infrastructure that contains 5,000 users.
You plan to deploy a persistent chat infrastructure.
You need to ensure that persistent chat rooms remain available if a Persistent Chat Server fails.
What should you do?

You have a Lync Server 2013 infrastructure that contains an Enterprise Edition front end pool.
You plan to add the following server roles to the existing infrastructure:
Edge Server
Archiving Server
Monitoring Server
Persistent Chat Server
You need to identify the minimum number of Microsoft SQL Server servers that must be added to the existing Lync Server 2013 infrastructure. The solution must
not use the existing SQL Server Back End Server.
What is the minimum number of SQL Server servers that you should identify?

Contoso Ltd. Case B
Overview
General Overview
Contoso, Ltd. is an international manufacturing company that has 30,000 users.
Contoso has the following departments: sales, research, marketing, human resources, executive, manufacturing, and legal. The sales department has 2,000 users.
All of the users in the sales department are located in the United States. The research department has 3,000 users. All of the users in the research department are
located in Europe.
Physical Locations
Existing Environment
Lync Server Infrastructure
Contoso has a Lync Server 2010 infrastructure that only uses internal instant messaging (IM) and presence, The infrastructure contains a single Enterprise Edition
Front End pool that services all of the users.
Contoso uses a SIP domain of contoso.com for all of the users.
Client computers have either Microsoft Office Communicator 2007 R2 installed or Microsoft Lync 2010 installed.
Before deploying Lync Server 2013 and migrating the users to Lync Server 2013, you implement a small pilot project to test the functionality of Lync Server 2013.
Problem Statements
The users in the pilot report that occasionally, they cannot sign in to Lync 2013.
Requirements
Business Goals
Contoso plans to upgrade to Lync Server 2013 during the next six months. Contoso must deploy all of the Lync Server conferencing and edge services. Contoso
must also configure federation with its parent company, which is named Proseware, Inc. Proseware is located in Europe and has an Office Communication Server
2007 R2 infrastructure.
Contoso must minimize hardware and software purchasing costs, while guaranteeing performance levels for all Lync Server 2013 workloads.
Planned Changes
Contoso plans to implement the following workloads in the Lync Server 2013 deployment:
Federation
Dial-in conferencing
External user access

Audio, video, and web conferencing
The ability to host Lync meetings that have external participants
The FQDNs of the edge services will be configured as shown in the following table.

Technical Requirements
Contoso identifies the following technical requirements for the planned deployment:
Only federation to Proseware must be allowed.
All of the edge services must use default ports.
WAN traffic and Internet traffic must be minimized.
All of the user contacts stored in Lync Server 2013 must be backed up. The sales department must have a dedicated dial-in conferencing number.
All other users in both the United States and Europe must use a pool of regional dial-in conferencing numbers.
If a single component fails, all Lync services must remain available without the need for manual intervention.
Performance degradation is acceptable during a component failure state.
The conversations of all the sales department users must be archived for 30 days.
The conversations of all the research department users must be archived for 90 days.
No other conversations must be archived. After the migration to Lync Server 2013, all client computers will have three months to upgrade to Lync 2013. After
three months, legacy clients must be blocked from accessing the Lync Server 2013 infrastructure.
Security Requirements
Contoso identifies the following security requirements for the planned deployment:
All Lync Server conferences must use a unique URL.
Each Internet-facing service must have one or more dedicated public IP addresses.
Only the users in the human resources department must be prevented from connecting to Lync Server remotely.
