For deploying a FortiGate VM using Terraform in AWS, the administrator must use:

B. Use the Name of the key pair.

Terraform and AWS SSH Keys: When deploying instances in AWS using Terraform, it is required to specify the name of the SSH key pair to enable key-based authentication to the instance post-deployment.

Configuration Syntax: The variable keyname within the Terraform configuration should match the exact name of the SSH key pair as it is stored in AWS. This ensures that Terraform can reference the correct key during the deployment process to set up SSH access to the FortiGate VM.

Terraform Variables: The variable "keyname" block in the Terraform configuration will look for the key pair name as it should be declared in the terraform.tfvars file or passed as a variable during execution. This does not require the key pair's ID or fingerprint, just its name.

References: The need for the SSH key pair's name in Terraform configurations for AWS deployments is outlined in the Terraform AWS Provider documentation, which specifies how resources should be provisioned using Terraform.
