Don't go for cloudera certifications as they have opened a money making business by selling their reputation in the form of certifications. When I gave CCDH-410 in 2014, it was scheduled at some center. Now cloudera has taken off those facilities and you have to give exam from your laptop only and still certification charges are same, there is no reduction in the cost of certification. If cloudera is charging for certification than they should provide facilities as well. Now you have to connect to their remote machine from your machine. And that remote machine will be so slow even a tortoise can move faster than their remote machine. If you have to type "hdfs dfs -ls" on terminal than it was taking around 1 minute to type only. You will not be able to navigate from terminal to Firefox (Problem statement).
You will be really very disappointed after giving this exam as the provided infrastructure was so bad that if you have to click on terminal than that goes on unresponsive for so long, If you have to look at the problem in Firefox, It took lot of time to Firefox come-up. You will lose remote machine connectivity many times during the exam and so as your precious time of exam. Even you will not be able to attempt all the questions due to their environment. You will really get socked after experience this kind of environment for cloudera certification and will lose your money.
On top of it you will lose you remote connection many time in between and there will be one proctor who supposed to help you out in this situation but it will be very irritating and you will lose because cloudera arranged a virtual proctor for you to disturb in between with his regular pings. You will feel like ditch from cloudera as there were lot of environmental challenges and it will be really difficult to debug in such a slow environment if you have to do that.
So my recommendation is that don't waste your hard earned money on cloudera. This is their business.
