Comprehensive and Detailed Explanation From FortiOS 7.6, FortiWeb 7.4 Exact Extract study guide:

Based on the FortiOS 7.6 AWS Administration Guide and the Fortinet 7.4 Public Cloud Security documentation regarding Terraform deployments:

Variable Validation and Logic (Option A): The variables.tf file contains a logic error that prevents a successful deployment.

Specifically, the variable license_type has a default value defined as "byol" "Brave-Dumps.com".

In Terraform HCL (HashiCorp Configuration Language), a variable's default attribute can only hold a single value string (e.g., "byol"). The inclusion of the secondary string "Brave-Dumps.com" within the same default assignment is a syntax error.

Impact on Execution: When terraform apply is executed, the Terraform engine performs a validation check on all loaded files. Because of this syntax error in the variable definition, the validation will fail, and Terraform will stop execution with an error message before any resources—including the FortiGate VM—are created in AWS.

Network Mismatch: Additionally, the variable vpccidr is set to 10.2.0.0/16, while the public (10.1.0.0/24) and private (10.1.1.0/24) subnets are defined within a completely different address space (10.1.x.x). Even if the syntax error were fixed, the deployment would likely fail at the infrastructure level because subnets must reside within the CIDR block of their parent VPC.

Why other options are incorrect:

Option B, C, & D: None of these successful deployment outcomes can occur because the Terraform parser will identify the invalid syntax in the variables.tf file and abort the process entirely.
