You must retain container stdout logs for 90 days and query them with KQL. What is the standard configuration?

1. ✓ A Enable Container Insights sending to a Log Analytics workspace with a 90-day retention setting (correct answer)
2. B Mount a persistent volume and write logs to disk
3. C Enable Application Insights profiler
4. D Use kubectl logs with a cron job

Shortcut: Container Insights ships stdout/stderr into the ContainerLogV2 table in Log Analytics, where retention is configurable and data is queryable with KQL.
