An administrator used the what-if tool to preview the changes to an Azure Bicep file. What will happen if the administrator applies these changes in Azure? (Choose one answer)
Comprehensive and Detailed Explanation From FortiOS 7.6, FortiWeb 7.4 Exact Extract study guide:
Based on the FortiOS 7.6 Azure Administration Guide and standard Azure Resource Manager (ARM) deployment practices, the what-if operation allows administrators to preview how a deployment will affect the current state of resources.
Interpreting the What-If Output (Option A): The exhibit shows the results of a change preview for a Virtual Network (vnet-002).
The symbol ~ (Modify) next to the VNet indicates that an existing resource is being updated rather than created or deleted.
The symbol - (Delete) next to tags.Owner: " Production " indicates that this specific tag will be removed from the VNet.
Crucially, the symbol + (Create) appearing inside the properties.subnets array next to index 0: indicates the addition of a new element. This confirms that a new subnet named subnet001 with the address prefix 10.0.0.0/25 will be added to the existing Virtual Network vnet-002.
Why other options are incorrect:
Option B: The text shows that the tag " Production " is being deleted (-), not that the VNet is being renamed to " Production. "
Option C: The what-if tool only displays the changes . While one subnet is being added (+), the tool does not show the deletion of other existing subnets. Therefore, we cannot conclude the resulting VNet will have only a single subnet; it will have its existing subnets plus the new one.
Option D: There is no mention of addressSpace or addressPrefixes for the VNet itself being modified (~) or added (+) in the exhibit; only a subnet-level address prefix is shown.
