At Citrix Education, we are often asked the following question:

What is the difference between CXA-201-2I Implementing Citrix XenApp 5.0 for Windows Server 2008 and CTX-1259BI Citrix Presentation Server 4.5 and XenApp 5.0 for Windows Server 2003?

The easiest answer to this is simply, the operating system. CTX-1259BI applies to XenApp 5.0 for Windows Server 2003 and CXA-201-2I applies to XenApp 5.0 for Windows Server 2008. However, the more complicated answer is…a lot of smaller differences, like features.

During the development of courseware, Citrix products, including XenApp, continue to evolve and change. We manage this constant change in two primary ways:

  1. We plan an update/maintenance cycle
  2. We include features late in development (if they have been announced)

These two approaches, while capturing most changes, cannot reflect all changes to the product. That’s why you may see a difference between what the courseware describes and what you can actually view in the live product. This, essentially, is the other fundamental difference between CXA-201 and CTX-1259. They each represent XenApp (on a different OS) at different times in XenApp evolution.

CXA-201-2I, available October 2, 2009, is the latest full course update on Citrix XenApp. It contains the most current and complete picture of XenApp on Windows Server 2008. CXA-201-1I, was the first release for the WS 2008 platform, and released in May of 2009. The features included in that course reflected XenApp 5 and nothing that has happened since…clearly, it was time for an update! Learn more about the delta between CXA-201-1I and CXA-201-2I (document also posted below).

In November 2009, we will release an update to CTX-1259BI. It will contain information including Feature Pack 2. Because it is available after the release of CXA-201-2I, it will become the course with the most current feature set of XenApp (WS 2003). Learn more about the delta between CTX-1259BI and CTX-1259CI (document also posted below).

In short, the main difference is the OS. The best choice for which class to take should be based on the OS on which you wish to learn. Or, if you are preparing for a platform migration from 2003 to 2008, we recommend CXA-201. To stay up to the minute current on new XenApp features, you can always reference the XenApp product pages.
