When setting up a Time Machine for a newly-provisioned database in NDB, the GUI allows the administrator to configure the frequency of snapshots for data protection. The maximum number of snapshots per day that can be configured in the NDB GUI is 6. This limit ensures a balance between data granularity (for point-in-time recovery) and storage overhead, preventing excessive resource consumption. The administrator can schedule these snapshots at regular intervals (e.g., every 4 hours) within the Time Machine configuration wizard.
Other options are incorrect based on NDB’s design:
A. 4: This is below the maximum supported limit.
C. 8: Exceeds the GUI-configurable maximum.
D. 12: Far exceeds the limit, suggesting manual or unsupported customization.
Thus, the verified answer is B, aligning with NDB’s snapshot scheduling constraints.
