Correct Answer: BTo collect detailed configuration information after completing an ONTAP cluster installation, the most suitable tool is the NetAppDocs output report. This tool can provide comprehensive documentation of the system's settings in various formats, which is necessary for creating a Service Event Report (SER). Active IQ scheduled reports and Active IQ Config Advisor worksheet do not offer the same level of detailed configuration documentation required for this task, and the ONTAP System Manager is more suited for management tasks rather than producing detailed configuration reports.
