If you have Silver or Gold with Microsoft your employer can save money on stuff like software. It's a worthwhile investment.

That's probably the biggest deal. I have the conception that a lot of the questions are about API specifics, which I tend to think is often easy to learn on the fly. Perhaps except for heavy-duty APIs such as WPF. I'd still like to get some more certifications, if only for the CV benefits it has.
