In Nutanix Database Service (NDB), alert retention is a configurable setting that determines how long alerts (e.g., system issues, performance warnings, or database events) are stored in the system for review and analysis. Based on NDB’s design and administrative policies, the maximum number of days allowed for alert retention is 180 days. This duration allows administrators to maintain a reasonable historical view of system health while preventing excessive data accumulation that could impact performance. This value is typically set as a default maximum in the NDB settings or via Prism Central integration, and administrators can adjust retention periods within this limit based on organizational needs.
Option A (90) is incorrect as it represents a shorter retention period, which may be a configurable minimum or intermediate value but not the maximum.
Option D (306) is incorrect as it is not a supported retention limit in NDB’s configuration options.
Administrators should verify this setting in the NDB UI under alert management or consult Nutanix support for custom configurations.
