You are evaluating the use of standard gateway devices that support eight T1 interfaces each. The gateways do not support media bypass. You need to recommend a so lution to support PSTN calls from the main office. The solution must meet the companys technical requirements. What should you include in the recommendation?
A.
Deploy four gateways and a single Mediation pool that contains two servers.
B.
Deploy six gateways and a single Mediation pool that contains six servers.
C.
Deploy four gateways and two Mediation pools that each contains a single server.
D.
Deploy six gateways and a single Mediation pool that contains two servers.
Explanation:
Gateways can be calculated: 1000/8/23 = 5.43, so four won’t fulfill the simultaneous calls requirement.There’s no need for six Mediation Servers though, because:
"New for the Mediation Server in Microsoft Lync Server 2010 is the ability for a single Mediation Server to route outbound calls through multiple gateways. In previous releases, there was a 1:1 ratio of Mediation Server to gateways." (http://technet.microsoft.com/en-us/library/gg425806.aspx)
