I have planned to complete NetApp NCDA Certification. just want to know the pre-requisite for the certification. does it require any specific training from NetApp or we can write it by preparing by our own.
There is a wealth of information on the the LearningCenter on Field Portal. I would recommend you do some online training prior to attempting your Certification.
The NCDA bootcamp will also be beneficial to you as this will ensure you have the relevant knowledge to attempt the exam. There is no substitute for hands-on experience and good luck in the pursuit of your Certification.
