The MCITP Enterprise Support Technician only requires two exams – 70-620 and 70-622. The 70-620 can be used for other certifications as well – so look carefully to maximize your testing experience.
If you are interested in the 70-620: TS: Windows Vista, Configuring exam, than you should have at least one year of experience in the IT field (working with Vista). You typically provide phone support at the tier-1 or tier-2 level in a wide range of environments, including retail stores and medium-sized organization or enterprise environment.
You should have extensive experience resolving issues concerning network connectivity, desktop operating systems, security, and applications. You should also have experience addressing logon problems, performing password resets, and resolving most issues with desktop applications.
The other exam required for the MCITP Enterprise support Technician assumes you have experience working in larger network environments. The 70-622: PRO: Supporting and Troubleshooting Applications on a Windows Vista Client for Enterprise Support Technicians exam (quite the title there) is aimed at IT professionals who primarily work in an upper mid-sized organization or enterprise environment that uses Windows Vista. You should have experience with previous versions of the Windows operating system (or even with Windows 7 – not testedbut good to know). You may also have experience with one of the Windows Server operating systems (2003 or 2008).
If you are planning on earning your MCITP Enterprise Support Technician you should have experience deploying Windows Vista, managing security, and troubleshooting network-related issues with Windows Vista. In contrast to the 70-620 exam which only required one year of experience, you should have at least three to five years of experience as a tier-2-level or lead desktop support technician.
