Updating the Cluster DBA Exam

It is time to update the MySQL Cluster exam. The current exam was written when the Cluster software was at version 5.1 and 7.0.5 is available for download. Reviewing the old exam questions shows some of them are badly dated.

But updating the exam requires more than simple edits of the questions. The MySQl 5.1 Cluster DBA Certification Study Guide is the book to use for studying for the exam. And having a study guide is a vital tool for those of us who prefer to self study for an exam. Sadly, some of the authors are no longer with Sun and I am sure those still around have minimal spare cycles in their schedule.

And it would be a waste of time if the revised exam is based on a version of software that is soon to be superseded. The Cluster product has evolved rapidly since it was introduced at a users conference years ago in Orlando and each release provides more features.

My 'virtual cluster', a Mac laptop with VirtualBox data nodes, is running a 6.0.x version and needs to be updated. I encourage those using any of the MySQL Study Guides to use the software with the examples in the book. Sometimes you can learn more by 'fat fingering' a command or finding something destined for the book's errata than reading the text alone.

But the first step is reviewing each question and determining if it requires updating. And, as the old adage goes, even the longest journey starts with the first step.

I do wish that I could help. I've got quite a lot of time and the software along with a fresh new(ish) copy of the 5.1 cluster dba certification study guide. And I'm great with turning the odd phrase.

But it might be best if this was performance-based, like the new 5.1 MySQL DBA exam. That would, of course, require a new Cluster DBA activity poll (yay).

Either way, allow me to express my disdain for multiple-answer questions (simple multiple choice is fine, but where you have questions that have correct answers of B, C and E is just annoying).
