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.
- An SIP trunk is an IP connection that establishes a SIP communications link between your organization and an Internet telephony service provider (ITSP) beyond your firewall. An SIP trunk is typically used to connect your organization’s central site to an ITSP. It may also be possible to use SIP trunking to connect your branch site to an ITSP.
- Conferences are secure and confidential because users who join using the Lync client, Lync Phone Edition, or Lync mobile client are already authenticated using Active Directory.
- Lync includes support for Windows PowerShell, which can be used to automate many administrative tasks. If you understand how to use PowerShell, you can be more efficient and effective performing these tasks.
- Monitoring communication services is necessary in order to ensure that end users are getting the desired service. You can use the monitoring features in Lync to determine if performance or outages are affecting communication services. Synthetic transactions allow you to quickly and easily determine real-time communication services health by performing transactions on client computers that simulate typical actions performed by users (such as initiating conference calls). Synthetic transactions provide an accurate representation of the end user experience. You can also use the Active Monitoring feature. This feature monitors resources to ensure they are adequate to support the current demands, including pools, servers, and available network bandwidth. If you are also using System Center 2012 or System Center 2007 R2 Operations Manager, you can monitor Lync health. Operations Manager provides centralized alerting of health issues and logging so that you can resolve issues before they affect user performance or availability.
