Has there been any word on when the NS0-156 test will use the CDOT 8.3 information? The classes are switched over now and are in a split format so I wasn't sure when the testing would change. Our instructor said it would be when GA hit, which it has.
Just wondering how long I have to wait to determine if I want to focus on another certification track before NetApp.
There have been no official annoucements in regards to the certification content being updated to clustered Data ONTAP 8.3. However, your instrucutors advice is sound. Unless you're planning on taking an exam in the new few weeks I would focus my studying on clustered Data ONTAP 8.3.
Updating an exam is a strenuous process that takes months of work so its impossible to time a new release to a GAs go live.
