NetApp Certified Support Engineer (NCSE) – ONTAP — Question 18

You have upgraded your cluster from ONTAP 9.5 software to ONTAP 9.7 software. After the upgrade, you notice that the upgrade causes issues. You decide to revert to ONTAP 9.5 software.
Which revert step is allowed?

Answer options

• A. Revert to ONTAP 9.5 software with the netboot procedure.
• B. Revert from ONTAP 9.7 software to ONTAP 9.5 software by using the boot backup procedure.
• C. Revert directly from ONTAP 9.7 software to ONTAP 9.5 software.
• D. Revert from ONTAP 9.7 software to ONTAP 8.6 software and then to ONTAP 9.5 software.

Correct answer: D

Explanation

The correct answer is D because reverting to an earlier version often requires stepping back through intermediate versions when a direct downgrade is not supported. Options A, B, and C are incorrect as they do not follow the supported downgrade path for ONTAP software.
