Topic 6, Contoso, LTD 2
Contoso, Ltd. is a Canadian business law firm that currently employs 300 people. The company operates a main office in Vancouver that houses 250 employees and a branch office in Seattle that houses 50 employees. All Contoso users are Skype for Business- enabled. Contoso is launching a hybrid configuration of Office 365 to validate the cloud- based Exchange Online service.
Contoso plans to introduce a remote disaster recovery data center to host remote replicas of key services, including Active Directory Domain Services (AD DS), Skype for Business, Exchange, and files and legal software. The company also plans to acquire a small law firm in Vancouver called Litware, Inc., which has 80 employees. Litware currently uses a 10- megabit per second (Mbps) Internet connection.
Half of Litware employees will use Skype for Business services. All Skype for Business- enabled users in Litware will use Instant Messaging only. Currently, Instant Messaging concurrent usage at Litware is 50 percent during peak hours.
There is a possibility that Contoso will make two more acquisitions during the next three years. Vancouver and Seattle employees have submitted support tickets to report poor quality of outbound Skype for Business calls to external users. A user activity report collected by the help desk department is shown in the User Activity Report section.
There is a concern that in the future, the volume of Skype for Business traffic may reach up to 50 percent of the current bandwidth available in the Vancouver office.
User Activity Report
Existing Environment
The core portion of the infrastructure is located in the Vancouver data center, although the
Seattle data center also has two servers (listed below) to provide redundancy of Active Directory and data services.
The following services and applications comprise Contoso’s infrastructure in Vancouver and Seattle.
Vancouver Data Center:
Seattle Data Center:
An overview of the network infrastructure of Vancouver and Seattle data centers is shown in the exhibit. (Click the Exhibit button.)
All users in the Vancouver and Seattle offices use the Microsoft Windows 8 Enterprise operating system and phones that are enabled for Enterprise voice.
Contoso expects to see a growing number of remote users. They anticipate that up to 20 percent of users in Vancouver might work remotely.
Contoso has defined a team of 35 users who will participate in a pilot deployment of the Office 365 hybrid configuration.
The offices in Vancouver and Seattle are using 5-Mbps Internet connections. Contoso has a site-to-site VPN between the Vancouver office and the Seattle office.
All external outbound calls from the Vancouver and Seattle offices are routed outside through the office in Vancouver.
Business Requirements
Contoso needs to review the existing network topology as well as the Skype for Business Server 2015 infrastructure to ensure that network capacity is sufficient to accommodate the Litware, Inc. Skype for Business users in the future.
Contoso expects to see up to 85 percent of simultaneous instant messaging, 1% of peer- to-peer traffic and 25 percent of public switched telephone network (PSTN) calls over the WAN during business hours.
All existing issues that relate to poor quality of outbound Skype for Business calls need to be addressed as well.
Contoso wants to ensure the following:
Current network bandwidth allocated to the Vancouver office is sufficient to sustain the future volume of Skype for Business traffic and guarantee high quality of Skype for Business calls.
Volume the Skype for Business traffic does not exceed 25 percent of the WAN bandwidth.
Contoso plans to redesign the existing site-to-site VPN solution between the Vancouver and Seattle offices to implement a robust and reliable WAN solution with end-to-end support of Quality of Service (QoS).
The recommended design solution needs to eliminate the possibility of WAN oversubscription by Skype for Business traffic.
The proposed Skype for Business Server 2015 solution needs to be: Scalable to accommodate the company’s future acquisitions. Readily available for Vancouver and Seattle users.
In case of a disaster, a manual switchover of Skype for Business services to the disaster recovery datacenter should be available.
Technical Requirements
All Session Initiation Protocol traffic (SIP) traffic must be encrypted.
All external Skype for Business Server 2015 services must be protected by a firewall. A commercial third-party certificate must be used on the external interface of Skype for
Business Server 2015 Edge servers.
The Role-Based Access Control (RBAC) model will be implemented to delegate basic administrative tasks to the Skype for Business help desk team.
All maintenance of Skype for Business servers must be performed outside of business hours.
The proposed architecture solution must support interoperability between Skype for Business Server 2015 and Exchange 2013.
The Skype for Business Bandwidth Calculator must be used to analyze Skype for Business traffic. The QoS end-to-end support needs to be implemented.

Topic 4, Trey Research
Trey Research is a global marketing research organization that has a main office in Moscow and branch offices in Los Angeles, London, Berlin, Copenhagen, and Jakarta.
The number of users per office is shown below:
The company has existing IP-PBX systems that are reaching end of life. They use an automatic call distribution (ACD) system for their help desk. This system provides interactive voice response options to users so that they can choose the location for support. This system is also reaching end of life.
The Copenhagen office uses a call group pickup solution that runs on an existing IP-PBX system. All users with the exception of users in Copenhagen have Direct Inward Dialing (DID) numbers.
Trey Research has Skype for Business Enterprise pools in the Moscow, London, and Berlin offices, respectively. They run a Unified Communications Managed API (UCMA) based application in a trusted application pool.
Two users who recently joined the company in the finance department report that they are not able to use the Aries phone even when tethering the phone to their PC.
Executives conduct global town hall meetings each quarter. Each meeting occurs in a different office. Employees attend the global town hall meetings in meeting rooms which are equipped with full high definition (HD) screens for video. Ten percent of the employees attend the audio portion of the global town hall meetings from their desk.
Trey Research plans to implement Skype for Business Enterprise Voice across the company to replace the existing IP-PBX systems.
You have the following requirements:
You must reduce international long distance calling costs, and lower support and administration costs foe the IP-PBX and ACD solutions.
You must implement voice survivability for all the sites in case of a wide area network (WAN) link failure.
Germany experiences high public switched telephone network (PSTN) call volume. All calls for Germany must breakout from Berlin in the event of Mediation Server pool failure in Berlin.
Existing gateways do not support the REFER method. You must use the existing gateways with Skype for Business to provide PSTN connectivity.
Where possible, you must optimize media paths.
All calls placed to Russia from any office must route through the Moscow gateways.
In the event of a failure of both gateways at any office, all international calls from that office must route through the Moscow gateways.
The solution must be resilient to the failure of mediation server pools.
All PSTN calls to Germany must use Berlin gateways in the event of Mediation Server pool failure in Berlin.
The maximum concurrent peer-to-peer connections between Moscow and Berlin will be 196.
Response groups must be managed by dedicated response group administrators.
You must use the following typical bandwidth values to determine the bandwidth requirements in kilobits per second (Kbps) for the solution:
Video resolution bandwidth:
Audio codec bandwidth:
