Microsoft Network Readiness and Assessment for Lync 認定 074-335 試験問題：
問題 #1
==========================
Topic 5, Lucerne Publishing
Background
Lucerne Publishing is an international publishing company headquartered in Seattle. Lucerne specializes in computer technology books and popular science magazines. The company was founded in 2001 and has since expanded significantly through multiple acquisitions. Lucerne Publishing has four main editorial offices, located in Seattle, Denver, London, and Beijing. The company also has more than 50 bookstores and publishing units distributed worldwide, with the biggest bookstore and library located in Glasgow.
Today the company has 2,900 employees worldwide:
Proof of Concept Deployment
Lucerne Publishing has a proof of concept (POC) deployment of Lync 2013.
During the POC testing, users reported the following: - In the Seattle office, there were significant delays in the Presence status updates. - In the Seattle office, the quality of audio calls is often poor during business hours. - In the London office, users often experience issues with video calls during
business hours, such as video freezing or video not being available during conferences.
The management team would like to rectify the issues which users have reported before proceeding with an implementation.
Existing Environment
The existing application environment includes the following components: - An Active Directory (AD) domain named lucepub.com with two regional subdomains named uk.lucepub.com and ch.lucepub.com. - A Microsoft Exchange 2010 organization with MS Exchange 2010 servers in Seattle and London.
The Beijing office has an Office Communications Server (OCS) 2007 R2 deployment, including Group Chat.
Each editorial office has a datacenter to support local infrastructures. The existing network infrastructure is configured as shown in the Network Topology Diagram exhibit.
The data centers connect to each other by using a Multiprotocol Label Switching (MPLS) network with wide area network (WAN) links that have the following characteristics:
Peak phone usage in the main offices is as follows:
Client computers in each office are connected to a switched 100 Mbps Power over Ethernet (PoE) port, and servers are connected to 1-Gigabyte per second (Gbps) Ethernet ports. Corporate firewalls are installed at all locations, and Quality of Service (QoS) is available globally on the network equipment.
Business Requirements
Lucerne Publishing has the following requirements to validate the POC Lync Server 2013 deployment:
- Evaluate audio call quality and confirm that the public switched telephone network (PSTN) long distance calls are not required for interoffice communication.
- Evaluate the new collaboration tools and services (including conference calls, audio and video calls, instant messaging (IM), and screen sharing) and obtain user feedback.
- Model the call flow of video conference calls for the Beijing office users who will need to continue using OCS 2007 R2 client software during the coexistence phase of the deployment.
- Estimate the effectiveness of replacing the local PSTN connections in each office with centralized session initiation protocol (SIP) trunking services (one per region: North America, Europe, and Asia).
- Ensure optimal audio quality of phone calls and conferences between all company offices.
- Support stereo audio for marketing and sales executives for internal conference calls to provide a high quality user experience.
Lucerne Publishing also requires that the following Lync 2013 components and maintenance tasks be evaluated:
- Back-end and network performance reports for business hours are generated on a daily basis. - Today's performance reports for the Seattle office and the London office are shown in the Performance Reports section. - The existing solution for monitoring network utilization between all major locations will trigger an alert if utilization becomes high.
Also, Lucerne Publishing has the following minimum requirements for the Beijing office: - Ensure that the office link is not saturated with Lync 2013 traffic, and that other
network services are not impacted by it. - Implement Call Admission Control (CAC) to ensure the quality of the connection. - Implement QoS to ensure that services other than Lync 2013 are not
compromised.
Scalability of the solution is very important to Lucerne Publishing. The company has future acquisition plans, and it must be easy to integrate new offices and sites into the existing infrastructure to provide enterprise voice, messaging, and email solutions. It should also be easy to add additional servers to the existing locations in case those location experience growth and add users.
Finally, the solution must provide high availability (HA) and disaster recovery (DR) capabilities. It must provide failover and voice resilience mechanisms in case of single server or entire pool or site failure. For branch offices, voice resilience must be increased by using Survivable Branch Appliances (SBAs) or Survivable Branch Servers (SBSs).
Technical Requirements
Lucerne Publishing will need to be able place a server offline for maintenance without impacting Enterprise Voice.
All Lync traffic should be encrypted, and integrated security of Lync devices should be used when possible.
The solution must support: - Microsoft Lync Phone Edition - Connections from the Lync app from Windows Store for Windows 8 and Windows
RT, and from Lync apps on mobile devices
- Interoperability with devices manufactured by participants in the Lync
Interoperability program
- Interoperability with Skype clients
The existing implementation of WAN/LAN/Wi-Fi and QoS must also be supported.
==========================
