Suggested Answer: A Vote an answer
Detailed Explanation:
* Rationale for Correct Answer: The resource group is declared as a data source, so its name is referenced with data.azurerm_resource_group.example.name. Appending -vnet creates the required virtual network name. Option A correctly produces a string such as my-resource-group-vnet.
* Analysis of Incorrect Options (Distractors):
* B. Incorrect. concat() is used to concatenate lists, not strings.
* C. Incorrect. join() expects a separator and a list of strings, such as join( " - " , [var.
resource_group_name, " vnet " ]). The syntax shown is invalid.
* D. Incorrect. This references a managed resource named azurerm_resource_group.example, but the exhibit shows a data source named data.azurerm_resource_group.example.
* Key Concept: Referencing data source attributes and using string interpolation/concatenation in Terraform expressions.
