Overview
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:
[Microsoft-70-333-1.0/xmlfile-2_1.png]
Existing systems and telephones
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.
All users in Trey Research are using Aries phones. Users authenticate by using PIN codes.
Quarterly global town hall meetings
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.
[Microsoft-70-333-1.0/xmlfile-3_1.png]
Trey Research plans to implement Skype for Business Enterprise Voice across the company to replace the existing IP-PBX systems.
Bandwidth Calculation Values
You must use the following typical bandwidth values to determine the bandwidth requirements in kilobits per second (Kbps) for the solution:
Video resolution bandwidth:
[Microsoft-70-333-1.0/xmlfile-4_1.png]
Audio codec bandwidth:
[Microsoft-70-333-1.0/xmlfile-4_2.png]
Requirements
You have the following requirements:
General
You must reduce international long distance calling costs, and lower support and administration costs for 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.
Where possible, you must optimize media paths.
The solution must be resilient to the failure of mediation server pools.
The maximum concurrent peer-to-peer connections between Moscow and Berlin will be 196.
Response groups must be managed by dedicated response group administrators.
Gateways
Existing gateways do not support the REFER method. You must use the existing gateways with Skype for Business to provide PSTN connectivity.
In the event of a failure of both gateways at any office, all international calls from that office must route through the Moscow gateways.
Outbound calls
All calls placed to Russia from any office must route through the Moscow gateways.
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.
All PSTN calls to Germany must use Berlin gateways in the event of Mediation Server pool failure in Berlin.
Enterprise Voice
You test the Enterprise Voice solution with users in the Copenhagen office. During testing, users reported audio call issues related to the Call Admission Control
(CAC) configuration. The relevant portion of the current configuration is shown in the Table below:
[Microsoft-70-333-1.0/xmlfile-5_12.png]
You create the following policies:
[Microsoft-70-333-1.0/xmlfile-5_13.png]
Problem Statements
Two users who recently joined the company’s finance department report that they are not able to use their Aries phones even when they tether the phone to their
computer.
HOTSPOT
You need to design a solution for the Mediation Server pools and trunks that are required to support London, Berlin, and Moscow users.
How many of each component should you deploy? To answer, select the appropriate number of Mediation Server pools and trunks from the lists in the answer
area.

Overview
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:
[Microsoft-70-333-1.0/xmlfile-2_1.png]
Existing systems and telephones
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.
All users in Trey Research are using Aries phones. Users authenticate by using PIN codes.
Quarterly global town hall meetings
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.
Bandwidth Calculation Values
You must use the following typical bandwidth values to determine the bandwidth requirements in kilobits per second (Kbps) for the solution:
Video resolution bandwidth:
[Microsoft-70-333-1.0/xmlfile-4_1.png]
Audio codec bandwidth:
[Microsoft-70-333-1.0/xmlfile-4_2.png]
Requirements
You have the following requirements:
General
You must reduce international long distance calling costs, and lower support and administration costs for 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.
Where possible, you must optimize media paths.
The solution must be resilient to the failure of mediation server pools.
The maximum concurrent peer-to-peer connections between Moscow and Berlin will be 196.
Response groups must be managed by dedicated response group administrators.
Gateways
Existing gateways do not support the REFER method. You must use the existing gateways with Skype for Business to provide PSTN connectivity.
In the event of a failure of both gateways at any office, all international calls from that office must route through the Moscow gateways.
Outbound calls
All calls placed to Russia from any office must route through the Moscow gateways.
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.
All PSTN calls to Germany must use Berlin gateways in the event of Mediation Server pool failure in Berlin.
Enterprise Voice
You test the Enterprise Voice solution with users in the Copenhagen office. During testing, users reported audio call issues related to the Call Admission Control
(CAC) configuration. The relevant portion of the current configuration is shown in the Table below:
[Microsoft-70-333-1.0/xmlfile-5_12.png]
You create the following policies:
[Microsoft-70-333-1.0/xmlfile-5_13.png]
Problem Statements
Two users who recently joined the company’s finance department report that they are not able to use their Aries phones even when they tether the phone to their
computer.
Users in Copenhagen report frequent audio call issues.
You need to resolve the issues.
Which three actions should you perform? Each correct answer presents part of the solution.
This is a case study. Case studies are not timed separately. You can use as much exam time as you would like to complete each case. However, there
may be additional case studies and sections on this exam. You must manage your time to ensure that you are able to complete all questions included on this
exam in the time provided.
To answer the questions included in a case study, you will need to reference information that is provided in the case study. Case studies might contain exhibits
and other resources that provide more information about the scenario that is described in the case study. Each question is independent of the other question on
this case study.
At the end of this case study, a review screen will appear. This screen allows you to review your answers and to make changes before you move to the next
section of the exam. After you begin a new section, you cannot return to this section.
