The 70-337 exam is meant to be taken by those who are IT consultants and telecommunications consulting professionals who design, plan, deploy, and maintain solutions for unified communications (UC). You should be able to translate business requirements into technical architecture and design for a UC solution.
Microsoft recommends that anyone taking this exam have a minimum of two years’ experience with Microsoft Lync technologies and be familiar with supported migration scenarios. Proficiency in deploying Lync Server 2013 solutions for end users, endpoint devices, telephony, audio/video and web conferences, security, and high availability are also required. In addition, you need to be proficient with Active Directory Domain Services, data networks, and telecommunications standards and components that support the configuration of Lync Server 2013 and should be familiar with the requirements for integrating Lync Server 2013 with Microsoft Exchange Server and Office 365.
After passing the Enterprise Voice & Online Services with Microsoft Lync Server 2013 (70-337) exam, you complete the requirements for the Microsoft Certified Solutions Expert (MCSE): Communication certification.

This passing score does not mean that you must answer 70 percent of the items correctly in order to pass the exam. The actual percentage varies from exam to exam and may be more or less than 70 percent. There is no penalty for guessing. No points are deducted for incorrect answers. If a question specifies that you must choose multiple correct answers, you must choose the exact number of correct answers specified in the question in order to earn a point for that item. Some of the questions on the exam may not count toward the calculation of your score. Microsoft will often throw a question in that is meant to gather data that will help them improve the exam.
As with any exam, it will vary from person to person as to what is deemed to be difficult. Be sure you are familiar with each of the topics in the exam objectives listed below.
- The improvements for Disaster recovery and high-availability include server pools with redundant roles. Although this is the same as Lync 2010, it is now possible to pair front-end pools in different data centers. This is important because if one pool goes down, the administrator can fail over to the other pool. You can also provide back-end server availability through SQL mirroring for the Lync databases.
- There are several new Enterprise voice features in Lync Server 2013, such as new routing features designed to improve enterprise voice. Support for multiple trunks between mediation servers and gateways and intertrunk routing will allow Lync Server to act as a go-between among different phone systems to include IP-PBX and a PSTN gateway. Also included is voice features such as manager/delegate simultaneous ringing (multiple designated phones ring at the same time), voicemail escape (which lets business calls on personal lines pass through to corporate voicemail), and caller ID presentation.
- Instead of having separate server roles for monitoring and archiving, new topology in Lync 2013 has moved both roles into the Front End Server role as optional features.
- Lync Server 2013 supports integration with Exchange Unified Messaging (UM) for combining voice messaging and email messaging into a single messaging infrastructure. In Microsoft Exchange Server 2013, Exchange UM runs as a service on an Exchange Mailbox server. In a Lync Server 2013 Enterprise Voice deployment, Unified Messaging combines voice messaging and email messaging into a single store that is available from a telephone (Outlook Voice Access) or a computer. Unified Messaging and Lync Server 2013 work together to provide call answering, Outlook Voice Access, and auto-attendant services to users of Enterprise Voice.
