Preparation for CCP Data Engineer Exam (DE575)

[#1]

I plan to get a Cloudera certification and need help on following questions:

Question #1. I reviewed the page https://www.cloudera.com/about/training/certification.html, It looks like that CCP Data Engineer is the only certification that has not been suspended or retired.  Am I right on this?

Question #2. To prepare DE575, the only recommended Cloudera course is "Spark and Hadoop Developer" training course. according to this page. https://www.cloudera.com/about/training/certification/ccp-data-engineer.html. Should I consider other courses?

Questions #3. My workplace uses HDP. Do I need to get familiar with products like CDH before taking the exam?

@Seaport If you haven't seen it already, please review the Cloudera Certification FAQ page for further information.

Please contact certification@cloudera.com with any additional questions.

@cjervis Thanks. I reviewed the FAQ page, but it does not answer my questions. I guess I'd better wait until tomorrow, because the page mentioned the date February 1, 2020 several times for new launches or other changes.

The certification team has updated the FAQ and posted an update on the community with new information.

I got the following responses from Cloudera Certification.
Regarding Question #1, the FAQ page has the most the up-to-date information. So right now I'd better hold off purchasing the exam until the DE575 is relaunched.
Regarding Question #2, the course is the "Spark and Hadoop Developer" training course is the one I should take for preparing DE575.
Regarding Question #3, the environment for the exam is fixed and only available on CDH. Candidates do not have the option to take the exam in an HDP environment. The skills tested are applicable to HDP development as well, it is in the developer track, so it should have nothing to do with the environment that it is running in. It is primarily interested in transforming data that sits on the cluster.
