Storage premium Table entity A Table entity is one record in Azure Table Storage. It behaves like a flexible row: it must have a PartitionKey and RowKey, it gets a service-managed Timestamp, and it can carry custom properties that your application defines.

Management and Governance premium Policy compliance state Policy compliance state is the status Azure Policy reports after evaluating a resource against an assigned rule. It tells you whether the resource appears compliant, non-compliant, exempt, conflicting, or not fully known for that evaluation. This is not just a dashboard color. It is the evidence operators use to decide whether a deployment broke a rule, whether a remediation task is needed, or whether an exemption is hiding risk. A learner should connect compliance state to a specific resource, policy assignment, definition, timestamp, and scope.

Management and Governance premium Policy state Policy state is the evidence record behind an Azure Policy compliance result. It answers practical questions such as which resource was evaluated, which policy assignment applied, whether the resource was compliant, and when Azure last knew that result. The portal summarizes these states, but operators often query them directly through Azure CLI, REST, or Resource Graph when they need proof. Policy state is especially useful when a dashboard says “non-compliant” and the team needs to locate the exact resource, policy, scope, and reason.

Management and Governance learning-path-anchor Tag value A tag value is the answer attached to a tag name. If the tag name is Environment, the value might be Production, Test, or Sandbox. If the name is CostCenter, the value might be a finance code. Values are where governance becomes meaningful, because they separate one owner, workload, data class, or lifecycle state from another.

Management and Governance learning-path-anchor Tagging strategy A tagging strategy is the playbook for using tags without making a mess. It answers simple but important questions: which tags are required, who owns the list, which values are allowed, where tags are applied, and what happens when a resource is missing one. Without a strategy, tags become random notes. With a strategy, tags become a dependable system for cost allocation, ownership, lifecycle cleanup, compliance evidence, and operational routing.
