VMware have extended the deadline for VCP3 holders to qualify for VCP4 certification without having to attend an official vSphere training course, you now have until January 31st 2010.
This move has been taken as many are finding it difficult to find a seat at a Pearson Vue testing centre before the previous deadline, December 31st 2009. In other words, in a similar fashion to Christmas shopping, too many people have left it until the last minute. VMware announced the VCP3 to VCP4 path back in the summer, and the exam has been available since the end of August.
Four of the Global Knowledge UK training centres are also Pearson Vue testing centres, and I know at the minute there are a huge number of people doing their VCP3 and VCP4 exams at our centres.
I've just finished delivering another VCP4 exam prep workshop, and we are now looking at scheduling another in London in January 2010, send me an email if you would be interested in attending our intensive 1-day prep session.
