The statement is incorrect for two primary reasons. First, the sysstat command is a legacy command for displaying a basic, one-line summary of system performance. Its output is customized using command-line flags (e.g., -x, -c, -i), not by external XML files. It is the modern statistics command family that utilizes XML preset files to customize performance data collection and display. Second, the correct directory for user-defined statistics preset files is /etc/stats/presets (plural), not /etc/stats/preset (singular).

True: This option is incorrect because it wrongly associates the sysstat command with the functionality of the statistics command framework. The sysstat command does not read XML files from any directory to modify its output. Furthermore, it specifies an incorrect directory path.

2. NetApp ONTAP 9 Commands Manual Page Reference: The manual page for statistics preset file create explicitly states

"This command creates a user-defined preset file. The preset file is an XML file that is stored in the /etc/stats/presets/ directory on the cluster." This confirms that XML preset files are used by the statistics command family and are stored in the /etc/stats/presets directory.

3. NetApp ONTAP 9 Performance Management Guide for Clustered Data ONTAP: This guide details the performance monitoring tools available in ONTAP. It distinguishes between the legacy sysstat command for quick checks and the comprehensive statistics command framework for detailed analysis

which relies on presets for customized counter collection and reporting.
