Greetings, The Exam Lab for HDPCA is painfully slow and it hangs all the time, Is there a way to make it perform better?

Is there any assistance I can get in this. I am planning to schedule for the HDPCA Exam very soon but my problem now is this. My fair is that I will face the same problem in the exam.

Hello, Mohamed.

What AWS instance type did you use for the practice?

The actual exam uses a slightly larger instance size than the recommended size on the practice. However, latency can also be caused by other factors like bandwidth. We recommend using a fast network in your area while taking the exam.

If you have any more questions regarding your particular case, please write to certification@hortonworks.com.

Hello @William Gonzalez,

Thanks for your reply. I tried instances from two different regions: US West ( Oregon) and US East (N. Virginia) and both were very slow. The internet speed is 16 MB and I don't think the problem is coming from here.

The type of the instances are: C3.Xlarge.

Mohamed-

You probably need at least a c3.2xlarge, if not c3.4x or c4.2x, since a c3.xlarge only has 7.5GB of memory. You should plan on having 16GB-32GB to run the VM smoothly.
