VMware have announced that the new vSphere: Troubleshooting course also now meets the vSphere training requirement for the VCP4 certification.
That now means you have three training course that meet the requirement for VCP4:
vSphere: Install Configure Manage
vSphere: Fast Track
Although all three of the courses qualify, be aware that the Troubleshooting course assumes that you already have at least the equivalent knowledge of the other two courses (and indeed the VCP4 itself).
The best of the three courses to attend in terms of which one is most closely aligned with the exam topics is currently the Fast Track. Global Knowledge UK already run the Install Configure Manage and Fast Track courses, and will start running the new Troubleshooting course from January 2010.
