Contoso has two main offices. The offices are located in Houston and Frankfurt. Each office has 15,000 users.
The offices connect to each other by using an MPLS network. Each office connects directly to the Internet.
Existing Environment
Lync Server Infrastructure
Contoso has a Lync Server 2013 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 Lync 2010 or Microsoft Lync 2013 installed.
Before deploying Skype for Business Server 2015 and migrating the users, you implement a small pilot project to test the functionality of Skype for Business
Server 2015.
Problem Statements
The users in the pilot report that occasionally, they cannot sign in to Skype for Business 2015.
Requirements
Business Goal
Contoso plans to upgrade to Skype for Business Server 2015 during the next six months. Contoso must deploy all of the 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 a Lync Server 2010
infrastructure.
Contoso must minimize hardware and software purchasing costs, while guaranteeing performance levels for all Skype for Business Server 2015 workloads.
Planned Changes
Contoso plans to implement the following workloads in the Skype for Business Server 2015 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.
[Microsoft-70-334-1.0/xmlfile-14_6.png]
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.
Wide area network (WAN) traffic and Internet traffic must be minimized.
All of the user contacts stored in Skype for Business Server 2015 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 Skype for Business 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 Skype for Business Server 2015, all client computers will have three months to upgrade to Skype for Business. After three months,
[Microsoft-70-334-1.0/xmlfile-14_14.png]
legacy clients must be blocked from accessing the Skype for Business Server 2015 infrastructure.
Security Requirements
Contoso identifies the following security requirements for the planned deployment:
All Skype for Business 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 Skype for Business Server 2015 remotely.

Question #10 (Topic: Testlet 3)
Overview
Background
Alpine Skihouse designs and manufactures skis and ski accessories. The corporate headquarters for the company is located in London. The company has a
design office in Rome and sales offices in Paris, Los Angeles, and Boston. The design team director works in the Rome office.
The company plans to implement Skype for Business Server 2015 to address their unified communications needs. The company currently has traditional PBX
implementations in each office location and uses a dial-in conferencing system that is hosted on their internal PBX.
The number of users in each office is shown in the following table:
[Microsoft-70-334-1.0/xmlfile-24_1.png]
Remote connectivity to all corporate resources and services is provided by SSL virtual private network (VPN) only. The current VPN solution tunnels all traffic to
the office. Internet facing services cannot be reached directly from users’ laptops when they are traveling.
Problem statements
During the requirements gathering process for the Skype for Business deployment project, users reported the following issues:
Users based in the United States report that they experience poor audio and video quality when they conduct meetings with users that are not located in the
United States.
Users based in the United States report that they experience poor audio and video quality when they conduct meetings and calls while they remotely
connected to the office.
The design team director would like customers to be greeted in the Italian language when they use dial-in conferencing to join meetings.
The sales team director organizes daily alignment meetings with local sales teams. He reports that there are issues with the quality of the audio and video.
Proposed solution
London
The following table shows the proposed London Skype for Business Server 2015 server architecture and IP addresses:

Requirements
Business requirements
The company has identified the following business requirements:
Users must be able to access all Skype for Business services when they work remotely.
The solution must support meetings with up to 10,000 users.
The solution must be highly available, and must withstand the loss of a single component at any point in time with as little interruptions of service as possible.
The language used by Skype for Business services must be localized wherever possible.
The leadership team in the Americas regions hosts an All Hands meeting for all employees four times per year. All employees are requested to join this
meeting. You must not install any additional servers to support this requirement.
Technical requirements
The company has identified the following technical requirements:
The SQL team has completed an upgrade of the entire SQL Server to the latest version. They require every SQL Server to use a SQL AlwaysOn Availability
Group as the high availability (HA) option.
There is no data center within the Boston site.
You must use the secondary data center in London to minimize the impact to users in the event of a single-site disaster.
Media traffic must only be encrypted once.
You must use the Skype for Business Management ShellInvoke-CsComputerFailOverandInvoke-CsComputerFailBackcmdlets to perform maintenance actions
during daily operations.
You must implement Domain Name System (DNS) load balancing wherever possible.
The current proposed solution for the Los Angeles site does not meet the business requirements.
You need to review, and if required, recommend changes to the planned implementation.
What should you do?
