I would like to know the study plan of Certification (401). can you help me the sites to download the dumps.
Here are some example questions but make sure you read the official documentation to get yourself prepared. I don't think you'll find actual exam dumps, but a lot of questions are the same, if not similar to what you find online. Just use google, he's your best friend!
Also go through the Study Guide for more detailed explanation of what the exam will look like.
And this is another question asked previously on this site regarding how to prepare.
