CertNexus are a vendor for professional certifications in the fields of IT, development and information security. I hold their CSC certifications (my CFR lapsed) and teach their CSC (cyber secure coder) class.
CSC-210 is a few years old, so they're now replacing it with the new CSD-110: cyber secure software developer. A few weeks ago they published the curriculum and exam blue print and this week they opened the beta-testing for the CSD-110 exam.
I have not had a chance to see their new training materials, which I assume they are still updating and making changes to. But today I sat the CSD-110 exam, to help them improve and test the new test.
In short: it was good!
I feel that these questions were well written! Some were a bit long to read, but overall the exam questions are not dry factual, but ask questions that require understanding and insight. The won't ask "what is the definition of phase X of the ATT&CK framework?", but more along the lines of "you observe X, Y and Z in your network and your team has determined that A and B. At which point in their kill chain are the attackers right now?".
With CompTIA beta exams I frequently leave large amounts of comments and feedback, pointing at bad wording or answers and questions that need improvement. With this exam I left very little feedback, meaning I really didn't see anything that wasn't good.
There was a decent diversity to the 80 questions I saw, although I would have liked to see more code and technical questions. It's called cyber secure software developer after all. But I assume that CertNexus has a large pool of questions and I simply got one particular mix of questions.
Having taken both CSC-210 and CSD-110 I will continue to stand behind this exam and training materials. I have now taught this class six times and every time the students come away feeling they learned a lot of useful new background. And as I said: I think this is honestly a good exam.
