Suggested rule

As per APRL recommendation, zone redundancy should be enabled by default in supported regions.
When using the Azure portal, zone redundancy is automatically enabled. However, some Infrastructure as Code (IaC) tools may default this to false. To ensure replication of metadata and events across data centers in an availability zone, always verify that zone redundancy is enabled.
