After passing the Implementing Data Models and Reports with Microsoft SQL Server 2012 (70-466) exam, you complete the requirements for the MCSE: Business Intelligence certification.

- Type of Questions: This test format is multiple choice and multiple choice multiple answer. You may also see several scenario questions.
- Passing Score: 700
- Time Limit: 120 minutes
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.
- Data Analysis Expression (DAX) is the expression language you use when creating calculated columns, measures, and KPIs for tabular models and PowerPivot models. The current release of SQL Server 2012 extends DAX to include many new statistical, information, logical, filter, and math functions.
- An Analysis Services instance can run in multidimensional, tabular, or PowerPivot for SharePoint server modes. Each server mode supports a different type of database by using different memory architectures, storage structures and engines.
- PowerPivot for Excel is a client application that incorporates SQL Server technology into Excel 2010 as an add-in product. In order to install the PowerPivot for Excel add-in, you must have Excel 2010 and Visual Studio 2010 Tools for Office Runtime installed. If you had already been using SQL Server 2008 R2 PowerPivot for Excel, you will have to uninstall first because there is no upgrade path for the add-in.
- PowerPivot for SharePoint requires that you install SharePoint Server 2010 and SharePoint Server 2010 Service Pack 1. Many people find it easier to install the PowerPivot for SharePoint instance and then use the PowerPivot Configuration Tool to complete the configuration of both the SharePoint farm and PowerPivot for SharePoint.
