I am a Magento 1.x developer and preparing for Magento certification. I may appear in exam for certification in next 5 to 6 months. If Magento 2.x is released before my exam then will i have to prepare for Magento 2.x also?
No. The Magento 2 certification will be a separate exam. You will not see Magento 2 content on the existing certification exams.
For awhile, being officially Magento 2 trained will substitute for Magento 2 certification until Magento 2 certification is available.
I am a Magento developer from Magestore.
About your questions, Magento 2.x certification is now still not available. Maybe the template will be different from Magento 1.x certification.
Don't worry. Let's practice and try hard for your exam.
