Difficulty: HardAzure Resource Manager (ARM) and ARM Templates/Bicep

An organization is using an Azure Resource Manager (ARM) template to deploy a virtual machine and a virtual network. Is it true that the virtual machine will automatically wait for the virtual network to be fully deployed first as long as the virtual network resource is defined earlier in the template file than the virtual machine resource?

Answer: Answer

Answer

The statement is false because Azure Resource Manager templates deploy resources in parallel by default, regardless of their order in the template file, unless explicit dependencies are defined.
The correct answer is False because ARM templates do not execute sequentially based on their file order. They are declarative, meaning resources are deployed in parallel unless explicit dependencies are established using 'dependsOn' or implicit reference links.

Step-by-Step Solution

1
Analyze the deployment model of Azure Resource Manager (ARM) templates.
ARM templates use a declarative syntax, meaning you define the desired end state of the infrastructure rather than the sequential steps to create it.
Understanding the difference between declarative and imperative models is key to knowing how resource creation is orchestrated.
2
Evaluate how ARM schedules resource creation and determines order.
ARM deploys resources in parallel by default to optimize deployment speed. It only enforces a sequence if an explicit dependency is defined using properties like 'dependsOn' in ARM templates or resource references in Bicep.
This determines whether the physical order of resources in the template file has any effect on execution sequence.
