Question 7

What is the purpose of Azure Resource Graph?

Accepted Answer

To query and explore Azure resource inventory and properties at scale using KQL. Azure Resource Graph is a service in Azure designed to enable efficient querying and exploration of resource inventory and properties across subscriptions at scale. It uses Kusto Query Language (KQL) to allow complex filtering, grouping, and aggregation of resource data, making it ideal for governance, compliance, and operational audits. This capability is distinct from visualization, diagramming, or billing tools.

Answer

To visualize the network topology of Azure virtual networks

Answer

To create visual diagrams of Azure architectural deployments

Answer

To track changes in Azure subscription billing

Question 8

What is the primary purpose of Azure subscriptions?

Accepted Answer

To serve as the billing unit and access boundary for Azure resources. Azure subscriptions serve as the primary billing unit, aggregating resource usage into a single invoice, and as an access boundary where Azure RBAC policies and management groups define administrative scope. Without a subscription, resources cannot be deployed or tracked for cost. This dual role makes B correct.

Answer

To provide a private network for Azure resources

Answer

To authenticate users accessing Azure resources

Answer

To enforce compliance policies across resource groups

Question 9

Which Azure tool provides personalized recommendations to optimize Azure resources for cost, security, reliability, performance, and operational excellence?
