While NetApp training is recommended to help prepare you for the exams, they are not required to take the exams. If you do not take the training, you should read as much material as possible related to the topics in the exam, and get some hands-on experience working with NetApp products.
If you have any questions related to trainings, please contact NetApp University at NetAppUSupport@netapp.com or if you have any questions about certifications, please contact ncp@netapp.com.
