If an administrator creates a report with no retention policy configured, how many instances of the report are retained by default?

When an administrator schedules a report in Nutanix Prism Central and does not specify a retention policy, the system applies a default setting. By default, Prism Central retains the 10 most recent instances of the generated report. When the 11th instance is generated, the oldest instance is automatically purged to maintain this limit. This default behavior helps manage storage consumption on the Prism Central virtual machine by preventing an indefinite accumulation of report files.

A. 5: This is an incorrect value. The default number of retained report instances is 10, not 5.
C. 15: This is an incorrect value. While a user can configure retention for 15 instances, it is not the system default.
D. 20: This is an incorrect value. The default retention count is 10, which is lower than this option.

1. Nutanix Prism Central Guide (pc-v2023.3), Section: Reporting, Subsection: Creating a Report. The guide states in the scheduling options: "In the Number of reports to retain field, enter the number of report instances to save. The default is 10."

2. Nutanix University, Nutanix Hybrid Cloud Fundamentals Courseware, Module: Prism Central, Section: Operations and Monitoring. The course material describes the reporting feature and explicitly mentions that if the retention count is not specified during report creation, it defaults to 10 saved instances.
