The snap restore command in NetApp ONTAP is an interactive command by default, meaning it prompts the user for confirmation before proceeding with the restore operation. This is a safety measure to prevent accidental data overwrites. For automation and scripting purposes, this interactive prompt must be suppressed. The standard method for achieving this is to use the -f (force) option with the snap restore command. This flag signals to the system to proceed with the operation without asking for confirmation, making it suitable for use in automated scripts.

A: The priv set advanced mode is used to access advanced commands and parameters for troubleshooting, not to suppress confirmation prompts for standard commands like snap restore.

B: The option snaprestorenoprompts does not exist in ONTAP. System-wide options are managed via the options command, but this specific option is fictitious.

D: This statement is incorrect. While the prompts are for data protection, they can be overridden using the -f flag specifically to allow for automation and scripting.

1. NetApp ONTAP 9 Command Reference: The man page for the snap restore command (and its modern equivalent volume snapshot restore-file) explicitly documents the -f or -force parameter. It states that this option forces the operation to proceed without prompting for confirmation.

Reference: NetApp ONTAP 9.8 Commands: volume snapshot restore-file man page. The -force parameter description states: "If you specify this parameter

the command proceeds without prompting for confirmation."

2. NetApp Data ONTAP 8.2 7-Mode Command Reference: For older systems

the snap restore command documentation shows the same behavior.

Reference: Data ONTAP 8.2 7-Mode Command Reference Guide

Page 789. The description for the -f option for snap restore states: "Ordinarily

snap restore asks for confirmation before it overwrites a file... The -f option suppresses this confirmation request."
