To get Terraform ready using Microsoft Azure Cloud Shell, you need to perform the following steps:

Set up a storage account in Azure.This is required to store the Terraform state file in a blob container, which enables collaboration and persistence of the infrastructure configuration1.

Use the wget (terraform_version) command to upload Terraform.This command downloads the latest version of Terraform from the official website and saves it as a zip file in the current directory2.

Move the Terraform file to the bin directory. This step extracts the Terraform executable from the zip file and moves it to the bin directory, which is part of the PATH environment variable.This allows you to run Terraform commands from any directory in Cloud Shell2.

The other options are incorrect because:

You do not need to use the -O command to download Terraform.This command is used to specify a different output file name for the downloaded file, but it is not necessary for this task3.

You do not need to subscribe to Terraform in Azure.Terraform is an open-source tool that can be used with any cloud provider, and there is no subscription or registration required to use it with Azure4.Reference:

A is incorrect because the terraform plan command will not deploy any resources at all. It will only show the changes that would be made if the terraform apply command was run.The error message in the exhibit indicates that the service principal details are invalid, which means that Terraform cannot authenticate to Azure and cannot create any resources1.

B is incorrect because you can run the terraform apply command without running the terraform plan command first.The terraform apply command will automatically generate a new plan and prompt you to approve it before applying it2. However, running the terraform plan command first can help you preview the changes and avoid any unwanted or unexpected actions.

C is correct because you must run the terraform init command once before the terraform plan command. The terraform init command initializes a working directory containing Terraform configuration files.It downloads and installs the provider plugins required for your configuration, such as the Azure provider2.It also creates a hidden directory called .terraform to store the plugin binaries and other metadata1. Without running the terraform init command, the terraform plan command will fail because it cannot find the required plugins or modules.

D is correct because the terraform plan command makes Terraform do a dry run. A dry run is a simulation of what would happen if you executed a certain action, without actually performing it.The terraform plan command creates an execution plan, which is a description of the actions that Terraform would take to make your infrastructure match your configuration2. The execution plan shows you what resources will be created, modified, or destroyed, and what attributes will be changed.The execution plan does not affect your infrastructure or state file until you apply it with the terraform apply command1.

This is because the Linux1 EC2 instance is not accessible directly from the internet using its public IP address in AWS.

An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet. Without an internet gateway, the Linux1 EC2 instance cannot receive or send traffic to or from the internet, even if it has a public IP address assigned to it.

To fix this issue, you need to attach an internet gateway to the Spoke VPC A and configure a route table that directs internet-bound traffic to the internet gateway. You also need to ensure that the Linux1 EC2 instance has a security group that allows inbound and outbound traffic on the desired ports.

The correct answer is A and C. A transport attachment and a connect attachment are necessary to connect a transit gateway to an existing VPC with BGP.

According to the AWS documentation for Transit Gateway, a transit gateway is a network transit hub that connects VPCs and on-premises networks. To connect a transit gateway to an existing VPC with BGP, you need to do the following steps:

Create a transport attachment. A transport attachment is a resource that connects a VPC or VPN to a transit gateway. You can specify the BGP options for the transport attachment, such as the autonomous system number (ASN) and the BGP peer IP address.

Create a connect attachment. A connect attachment is a resource that enables you to use your own appliance to provide network services for traffic that flows through the transit gateway. You can use a connect attachment to route traffic between the transport attachment and your appliance using GRE tunnels and BGP.

The other options are incorrect because:

A BGP attachment is not a valid type of attachment for a transit gateway. BGP is a protocol that enables dynamic routing between the transit gateway and the VPC or VPN.

A GRE attachment is not a valid type of attachment for a transit gateway. GRE is a protocol that encapsulates packets for tunneling purposes. GRE tunnels are established between the connect attachment and your appliance.

Based on the provided exhibit showing an active-passive FortiGate High Availability (HA) pair with external and internal Azure load balancers and without the use of an SDN connector, the administrator should implement a Probe IP address with two static routes (Option B).

Probe IP Address: Azure load balancers use a health probe to determine the health of the instances in the backend pool. The health probe ensures that the load balancer only directs traffic to the active (primary) FortiGate in an HA pair.

Two Static Routes: Given that this is an active-passive setup, static routing should be used to ensure deterministic traffic flow. Two static routes would be configured to ensure that traffic can flow to the active unit and be correctly routed to the protected subnets in failover scenarios.
