Hi Taofik.
The 70-410 and 70-411 exams are part of the
MCSA Windows Server 2012 certification, the 70-742 is related to the
MCSA Windows Server 2016 certification: you have to complete all the exams for each Windows Server version to get the related MCSA certification (e.g.: 70-410, 70-411 and 70-412 for MCSA Windows Server 2012).
Bye.
