This has been somewhat discussed before:
Are DBA certification questions appropriate?
Can I ask conversational questions? (Training)
I think the vast majority of questions about certification will be off-topic for one of the usual reasons, but that's not quite the same as saying that any question that mentions certification will be automatically off-topic.
We should continue to evaluate each question on its merits.
Regarding the specific examples:
How to validate and upgrade my knowledge of SQL Server with MCSA - closed.
What are the necessary course requirements to become a DBA? - closed
I couldn't immediately find a (non-deleted) example for "How do I get certified for [xyz]" but similar questions seemed very likely to be closed or deleted already.
There are only two questions in total tagged certification, both of which are now closed, so I'm not sure I see any value in this tag at all.
I'm tempted to say we should delete the two closed off-topic questions so the tag naturally expires.
I just submitted a tag wiki edit for certification containing the following:
It seems odd to edit the wiki to say certification questions are off-topic while at the same time asking if that is so on meta! Also, there are only 2 questions tagged this way today. My feeling is that this sort of advice in tag excerpts or wikis is not particularly effective (or desirable in general).
On the basis that we haven't established that all questions tagged certification will always be off-topic, I have rejected the wiki edit.
- I have removed certification from the two questions mentioned. It will cease to exist in due course.
- Now completed - the tag has gone.
