Microsoft Enterprise Voice & Online Services with Microsoft Lync Server 2013 Sample Questions:
You need to recommend a solution to prevent calls to the Boston office from being routed over the PSTN. The solution must meet the Lync Server requirements. What should you include in the recommendation?
- A. Two Lync Server 2013 trunks
- B. Two Lync Server 2013 Edge Servers
- C. A Lync Server 2010 A/V Conferencing pool
- D. A Lync Server 2013 Director pool
Correct Answer: A 🗳️
Explanation: Only visible for DumpTorrent members. You can sign-up / login (it's free).
You have a Lync Server 2013 infrastructure. You have one Enterprise Edition pool named pool1. contoso.com. Enterprise Voice is enabled for all users. You have a PSTN gateway named mg1.contoso. com that does not support secure signaling. The Encryption support level of the global trunk configuration is set to Not Supported. You add a second PSTN gateway named mg2.contoso.com. The SIP General parameters for mg2.contoso.com are configured as shown in the following table.
On mg2.contoso.com, you generate and install a certificate from an internal certification authority (CA). You need to ensure that Lync Server 2013 can use both PSTN gateways to make calls on the PSTN. Which four actions should you perform? To answer, move the four appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Correct Answer:

Explanation:
When defining a PSTN gateway in Topology Builder, you must define a root trunk to successfully add the
PSTN gateway to your topology.
The root trunk cannot be removed until the associated PSTN gateway is removed.

Each orbit range typically encompasses 100 or fewer orbits, but it can be much larger as long as it includes fewer than 10,000 orbits. For example, instead of specifying a starting number of "7000000" and an ending number of "8000000," consider specifying a starting number of "7000000" and an ending number of "7000100." 0-99 is too dew. 100-199 makes better sense
200-9999 and Pool1.contoso.com, which I agree with.
From the Scenario - at any given time, a maximum of 25% of users in NY are on the phone. A max of 20%
of calls are to the PSTN.
4000 users in NY office so 4000 * .25 * 0.20 = 200 max number of users that can be put on hold. The range
needs to be at least 200.
I think the answer should be:
Range: 200-9999
Application Server: Pool1.contoso.com

Note: The Mediation Server translates signaling and, in some configurations, media between your internal Lync Server 2013, Enterprise Voice infrastructure and a public switched telephone network (PSTN) gateway or a Session Initiation Protocol (SIP) trunk. On the Lync Server 2013 side, Mediation Server listens on a single mutual TLS (MTLS) transport address. On the gateway side, Mediation Server listens on all
associated listening ports associated with trunks defined in the Topology document. All qualified gateways
must support TLS, but can enable TCP as well. TCP is supported for gateways that do not support TLS.
The main functions of the Mediation Server are as follows:
The following figure shows the signaling and media protocols that are used by the Mediation Server when
communicating with a basic PSTN gateway and the Enterprise Voice infrastructure.
