Wingtip Toys is a toy manufacturer and distributor in North America. The company has a main office and two branch offices. The main office is located in New York. The branch offices are located in Boston and Chicago.
The number of users in each office is shown in the following table.
The network contains an Active Directory forest named wingtiptoys.com.
The New York and Boston offices connect to each other by using a 100-megabit per second (Mbps) WAN link. The New York and Chicago offices connect to each other by using a 40- Mbps WAN link.
Exchange Server Infrastructure:
The company has a Microsoft Exchange Server 2010 Service Pack 2 (SP2) organization. All of the users in the New York and Chicago offices have Exchange Server mailboxes. The users in the Boston offices do not have mailboxes.
The Exchange Server organization contains two servers. The servers are configured as shown in the following table.
Lync Server 2010 Environment:
The company has a Lync Server 2010 infrastructure that contains four components. The components are configured as shown in the following table.
All of the New York and Chicago users use Lync services. The Boston users only use IP- PBX phones.
Only the New York users are configured for on-premises Exchange Server Unified Messaging (UM).
The hardware components of the current voice infrastructure are configured as shown in the following table.
At any given time, a maximum of 25 percent of the users in the New York office are on the phone. A maximum of twenty percent of the calls are to the PSTN.
The company is evaluating Microsoft Lync Online.
The company moves 20 Chicago users to a Lync Online subscription. The subscription is configured to use a SIP domain of tailspintoys.com.
You did not implement directory synchronization or federation.
Currently, all of the calls between the New York and Boston offices are routed through the PSTN.
The audio and video quality during web conferences between the Lync users in the Chicago and New York offices often is poor.
Inbound and outbound PSTN calls from the New York office are not redundant. If a PSTN gateway fails, calls are not rerouted to another PSTN gateway.
The company plans to implement the following changes:
Upgrade the Lync Server 2010 infrastructure to Lync Server 2013.
Pilot Lync Online for 100 users in the Chicago office.
Ensure that Lync Online users can find on-premises Lync users in the Lync Address Book.
Ensure that Lync on-premises users and Lync Online users can communicate with each other by using instant messaging (IM).
Lync Server Requirements:
The company identifies the following Lync Server requirements:
Ensure that the New York users and the Boston users who have IP-PBX phones can call each other without using the PSTN.
Improve the audio and video quality during the web conferences between the Chicago users and the New York users.
Unified Messaging Requirements:
The company identifies the following Unified Messaging requirements:
Pilot integrated voice mail in Microsoft Exchange Online for 100 New York users.
Configure all users to have a five-digit extension.
Ensure that users can retrieve their voice mail remotely by dialing +1 516 555 1212.
Ensure that callers can reach the company directory by dialing +1 516 555 1213.
Prevent users from receiving an email message when they miss a call.
Three company executives require a second phone number for their existing Lync account. This second phone number must not appear in any Lync address books or contact lists generated from Active Directory.
Any planned changes must minimize administrative and financial costs.
You identify the following network requirements for the planned deployment of Lync Server 2013:
Limit the total bandwidth of all audio and video sessions from the Chicago office.
Reduce the network utilization of Mediation servers.
Prioritize Lync audio traffic on the network.
