The NKPA course explains that NKP uses Grafana Loki as part of its logging stack to implement a multi-tenant logging system, allowing teams to access their logs securely within their respective namespaces. The exhibit indicates two namespaces, tenant-innovation and tenant-analytics, each with a ConfigMap for logging configuration. The requirement is to set a retention period of 30 days for tenant-innovation and 7 days for tenant-analytics.

The correct YAML output (Option A) configures Loki’s retention period using ConfigMaps in the appropriate namespaces:

For tenant-innovation, the ConfigMap logging-innovation-config in the tenant-innovation namespace sets retention_period: 30d.

For tenant-analytics, the ConfigMap logging-analytics-config in the tenant-analytics namespace sets retention_period: 7d.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “In NKP, configure multi-tenant logging with Grafana Loki by creating a ConfigMap per namespace, specifying retention periods under loki.structuredConfig.limits_config.retention_period (e.g., 30d for 30 days, 7d for 7 days).” The d suffix denotes days, aligning with the requirement for 30 days and 7 days retention periods.

Incorrect Options:

B: The second ConfigMap incorrectly uses the tenant-innovation namespace instead of tenant-analytics, breaking the multi-tenant isolation.

C: The retention periods are set to 30h and 7h (hours), not 30d and 7d (days), which does not meet the requirement.

D: Both ConfigMaps use a generic tenant namespace, which does not match the specific namespaces (tenant-innovation, tenant-analytics) shown in the exhibit.
