MCSE in windows server 2012 goes, you will be able to get down and earn the MCSA 2012 first. The MCSA gets you past exams 70-410 (installing & configuring), 70-411 (administering), and 70-412 (configuring advanced services), after which you need to complete only two more infrastructure exams: 70-413 (designing and implementing) and 70-414 (implementing and advanced) to finish up your MCSE. If you do decide to go for this — and I think you should — look around for bundle or package deals on self-study materials (including Exam Crams which should be coming out in the next 2-3 months for all these topics), exams, and classroom or online training (if your budget and interest extend that far). You can usually save 15-25% or more off the cost of single-shot purchases of any of these things by buying them in bulk instead. In Microsoft exams they will provide you some offers like second attempt in one chance if you see such options can get the Microsoft Second Shot deal when you buy your exams (or vouchers for some, which is often a better deal) so that if you should happen to fail a first try on any one of those exams, you’ll be eligible to take a second try for no additional cost. That’s the advantage you will get in this options, but bundles stay good through the end of this year, which is another inducement to buy a bundle as well.
In companies they don’t change the server OS quickly it will take some time to change by that time you can update to the new server OS if you know server 2012 you can learn server 2016 very fastly and get certification in a single update exam. One server OS is released it will take 4-5 years of time to release the next server OS. This should give you time to train up, pass the exams, and jump on the Server 2012 bandwagon in this time most of the companies are using windows server 2012 OS The Companies will take some time to further updation so you still have a future in windows server 2012 OS. If you take your time, you should be able to finish your MCSA and MCSE 2012 in a year or so. If you want to put the pedal to the metal, it will still take you at least 5-6 months to work your way through all 5 exams.
