The Azure SDN connector uses two types of queries to interact with the Azure management API. The first query is targeted to a special IP address to get a token. This token is used to authenticate the subsequent queries. The second type of query is used to retrieve information about the Azure resources, such as virtual machines, network interfaces, network security groups, and public IP addresses. Some queries are made to manage public IP addresses, such as assigning or releasing them from the FortiGate VM. References: Configuring an SDN connector in Azure, Azure SDN connector using service principal, Troubleshooting Azure SDN connector

Terraform manages and tracks the state of infrastructure resources through a file known as terraform.tfstate. This file is automatically created by Terraform and is updated after the application of a Terraform plan to capture the current state of the resources.

State File Purpose: The terraform.tfstate file contains a JSON object that records the IDs and properties of resources Terraform manages, so that it can map real-world resources to your configuration, keep track of metadata, and improve performance for large infrastructures.

State File Management: This file is crucial for Terraform to perform resource updates, deletions, and for creating dependencies. It's essentially the 'source of truth' for Terraform about your managed infrastructure and services.

References: This behavior is documented in Terraform's official documentation, which explains how the terraform.tfstate file is used to keep track of the infrastructure Terraform is managing.

According to the AWS documentation for Transit Gateway, a transit gateway is a network transit hub that connects VPCs and on-premises networks. A transit gateway route table is a set of rules that determines how traffic is routed among the attachments to the transit gateway1.

A transit gateway can have multiple route tables, and you can associate different attachments with different route tables. This allows you to control how traffic is routed between your VPCs and VPNs based on your network design and security requirements1.

The other options are incorrect because:

Both the TGW attachment and propagation must be in the same TGW route table is not true. You can associate an attachment with one route table and enable propagation from another attachment to a different route table. This allows you to separate the routing domains for your attachments1.

A TGW attachment can be associated with multiple TGW route tables is not true. You can only associate an attachment with one route table at a time. However, you can change the association at any time1.

The TGW default route table cannot be disabled is not true. You can disable the default route table by deleting all associations and propagations from it. However, you cannot delete the default route table itself1.
