2017 CCDE Exam dates has been announced.There are four CCDE exam every year. More precisely there are four CCDE Practical/Lab exam every year. There is no limitation for the CCDE Written exam.
You can join CCDE Written exam anytime in any Pearson Vue Center. It is not only 4 times in a year.
CCDE Practical exam is not only in the Cisco Office anymore, but it is in the Professional Pearson Vue Locations. There are 275 of them and unfortunatelly, not every country has PPC (Professional PearsonVue Center)
If you are in Middle East, India, Turkey, Greece and Europe would be nice location.
I attended and passed the exam in Greece and Athens is one of the most beautiful city guys ? I definitely recommend it.
