  • At least one year of previous hands-on Lync Server experience designing, installing, configuring and supporting across all workloads, with an emphasis on voice and video, in small and mid-size enterprise deployments.
  • Functional understanding of Lync Server architecture and design including designs that feature multiple locations/pools, all Lync workloads and requirements for high availability.
  • Candidates new to Lync/OCS should complete formal training in 10533AD Deploying, Configuring and Administering Microsoft Lync Server 2010 and10534AD Planning and Designing a Microsoft Lync Server 2010 Solution.
  • It is also recommended for candidates to have passed both the TS and PRO Exams (100/200 level):

Exam Details

  • Number of Questions: Approximately 45-55 questions (Since Microsoft does not publish this information, the number of exam questions may change without notice.)
  • Types of Questions: This test format is multiple choice and multiple choice multiple answer. You may also see several scenario questions.
  • Passing Score: 700
  • 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.

  • Time Limit: 120 minutes

Trouble Spots

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.

  • Lync Server 2010 is not available in a 32-bit version. Lync Server 2010 is available only in 64-bit, which requires 64-bit hardware and 64-bit editions of Windows Server. All server roles and computers running Lync Server administrative tools run a 64-bit edition operating system.
  • Lync Server 2010 does not support SQL Server 2008 32-bit edition, SQL Server 2008 R2 32-bit edition, or SQL Server 2005 32-bit edition. You must use the 64-bit edition. SQL Server Web edition and SQL Server Workgroup edition are not supported and cannot be used with Lync Server 2010.
  • The Lync Server 2010 Mobility Service can support mobile clients only over your internal Wi-Fi network, but you must configure the internal Web Services VIPS for cookie
  • If your organization requires that you locate IIS and all Web Services on a drive other than the system drive, the installation location path for the Lync Server files can be changed in the Setup dialog box. If you install the Setup files to this path, including OCSCore.msi, the rest of the Lync Server 2010 files will be deployed to this drive as well.
  • Whether you are deploying audio or video devices, the device rollout and user training are important issues for you to consider and plan.
  • If the Lync Server databases are co-located with other databases, it is recommended assessing all factors that might affect availability and performance to show that if a node fails, the remaining node can handle the load. It is recommended that you test your failover scenarios.
  • To protect the necessary bandwidth on your network, you can deploy a Quality of Service (QoS) protocol such as Differentiated Services (DiffServ). You should coordinate the Lync Server 2010 CAC bandwidth policies you define with any QoS settings that you might deploy.
  • Lync Server 2010 has three advanced Enterprise Voice features:
    • Call admission control (CAC)
    • Emergency services (E9-1-1)
    • Media bypass.
  • These features share certain configuration requirements for network regions, network sites, and association of each subnet in the Lync Server topology with a network site.
  • CAC requires that every network region have an associated Lync Server central site, which manages media traffic within the region.
