Sadanand Khatri, I assume that your question is about the availability zone and zone redundancy support for Application Insights (if your question is about something else, please share additional context to help us understand it better).
Application Insights supports Zone redundant resiliency, when it is workspace-based, and the workspace uses a dedicated cluster. For supported regions with this support, see the following link - Azure Monitor: Data resilience - supported regions
For more details, also see - Availability zone service and regional support.
Hope this helps. If your question was about something else, please share additional context/information to help us better understand it.
