Q1. - (Topic 1)
You collect the following call statistics for users in Los Angeles:
✑ Peak call concurrency is 25 percent.
✑ Fifty percent of all placed calls are routed to the public switched telephone network (PSTN)
✑ Thirty percent of all placed calls are internal calls to users in the other offices.
✑ Twenty percent of all placed calls are conference calls.
✑ The average bandwidth for peer-to-peer calls is 65 kilobits per second (Kbps).
✑ The average bandwidth used for conference calls is 100 Kbps.
You need to allocate the minimum amount of bandwidth required on the wide area network (WAN) link for the planned implementation of the voice gateway in the Los Angeles office. All calls to the PSTN will be routed through the local voice gateway in the Los Angeles office.
How much bandwidth in megabits per second (Mbps) should you allocate?
A. 7.20 Mbps
B. 3.95 Mbps
C. 10.00 Mbps
D. 2.25 Mbps
Answer: A
Q2. DRAG DROP - (Topic 7)
Contoso, Ltd., has five offices. The offices are configured as shown in the exhibit. Click the Exhibit button.
Each office has a local connection to the public switched telephone network (PSTN). The peak usage statistics are shown in the following table:
Every audio call consumes 100 kilobits per second (Kbps).
You plan to replace the PSTN connection with a centralized SIP trunking service. The service will contain a Sip trunk in the Seattle office and a SIP trunk in the Amsterdam office. The solution must use least cost routing.
You need to calculate the maximum amount of bandwidth that will be used by each SIP trunk.
What is the maximum amount of bandwidth that will be used by each SIP trunk? To answer, drag the appropriate bandwidth amount to the correct SIP trunk in the answer area. Each bandwidth amount 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.

Q9. - (Topic 7)
You support a Skype for Business Server 2015 environment that consists of the following:
A single Skype for Business Server 2015 Standard Edition pool that is located in a main office.
Four branch offices that are connected by a 9 megabits per second (Mbps) dedicated wide
