Good morning and thanks for all.i have problem opening thé labs exercice15 votes
We have reworked the Cognitive Class Labs infrastructure to make it much more resilient and highly available. We have also increased performance in the process especially as it applies to the time it takes to start a lab.
I have attempted for one test and was failed to score 60% mark. I have prepared for the exam again , but there is no option for second attempt.
You should provide option for re-attempt after 10 days or some limit.419 votes
Thank you all for your suggestion to allow retaking of the final exam. We are very happy to report that we have added this capability to our platform and are in the process of updating all courses to allow for multiple attempts at passing an exam.
Each course author will create their own policy for the number of attempts allowed as well as the waiting period between attempts.

According to our tests and our mailer logs the emails have been sent.
It seems there’s an issue on
cognizant.com email service preventing users to receive emails from adminbigdatauniversity.com.
Please contact your system administrator to resolve it.

We had an issue that was preventing scores to be synchronized with Big Data University but that’s already fixed now.
Please follow the course FAQ instructions to update your missing scores:
My score for a lab is missing?
If the score of a chapter is not present, try clicking the link to that chapter again and submitting the first answer (your score is recalculated and sent back each time you submit an answer for the Chapter). Make sure to log out and log in to Big Data University after that!
If a mere visit to the site can lead to contracting virus or malware, what's the point in joining here? Or is it some specific downloads that one must beware of?1 vote

There is a typo in the option. Unfortunately the typo is in the right answer. This is not good. Nobody will get it right.
