So you know, "Cluster Mode" is no longer the term we use. We now use Data ONTAP or just ONTAP. I would recommend that you start with the NetApp Certified Data Administrator, ONTAP certification. You can find more about this certification here. To help prepare for this certification, I would check out this page which lists the recommended steps to help prepare you for the exam. This includes NetApp approved training courses, a Reference Document which lists documentation, white papers and other sites that can be referenced to help prepare you for the exam, as well as a practice test. Then, when you are ready to take the exam, you can go to Pearson VUE to register for the exam.
Once you pass the NS0-158 exam to earn your NCDA ONTAP certification, I would recommend looking into the NetApp Certified Implementation Engineer certifications, either the NCIE SAN ONTAP or the NCIE Data Protection.
Please let me know if you have any additional questions.
