Fortinet Updated NSE7_PBC-7.2 Exam Questions and Answers by scarlet

A. Use the terraform destroy command. This command is used to remove all the resources that were created using the Terraform configuration1. It is the opposite of the terraform apply command, which is used to create resources. The terraform destroy command will first show a plan of what resources will be destroyed, and then ask for confirmation before proceeding. The command will also update the state file to reflect the changes. D. The administrator must manually delete the Linux server. This is because the Linux server was not deployed using Terraform, but using AWS Marketplace2. Therefore, Terraform does not have any information about the Linux server in its state file, and cannot manage or destroy it. The administrator will have to use the AWS console or CLI to delete the Linux server manually.

The other options are incorrect because:

There is no terraform validate command. The correct command is terraform plan, which is used to show a plan of what changes will be made by applying the configuration3. However, this command does not delete any resources, it only shows what will happen if terraform apply or terraform destroy is run.

There is no terraform destroy all command. The correct command is terraform destroy, which will destroy all the resources in the current configuration by default1. There is no need to add an all argument to the command.

A is incorrect because the FortiGate public IP is not the next-hop for all the traffic. The FortiGate public IP is only used for incoming traffic from the internet. The Azure load balancer distributes the incoming traffic to the active FortiGate VM based on a health probe123. The FortiGate public IP is not used for outgoing traffic or internal traffic.

B is correct because an internal load balancer listener is the next-hop for outgoing traffic. The internal load balancer listener is configured with a floating IP address that is assigned to the active FortiGate VM. The internal load balancer listener also has a health probe to monitor the status of the FortiGate VMs123. The internal load balancer listener forwards the outgoing traffic to the internet through the public load balancer.

C is incorrect because you do not need to add a route to the Microsoft VIP used for the health check. The Microsoft VIP is an internal IP address that is used by the Azure load balancer to send health probes to the FortiGate VMs123. The Microsoft VIP is not reachable from outside the Azure network and does not require any routing configuration on the FortiGate VMs.

D is correct because a dedicated management interface can be used for load balancing. In this deployment, port4 is used as a dedicated management interface that connects to the management network3. The dedicated management interface can be used to access the FortiGate VMs for configuration and monitoring purposes. The dedicated management interface can also be used to synchronize the configuration and session information between the primary and secondary devices in an HA cluster2.

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.

For Transit Gateway Connect peers in an IPv4 BGP configuration, the correct statements are:

The inside CIDR blocks are used for BGP peering (Option A): In a BGP configuration for Transit Gateway Connect, the inside CIDR blocks, typically within the 169.254.0.0/16 range, are designated for the BGP peering connections. These blocks are reserved for internal network protocols and are commonly used in AWS for automatic IP address assignment within managed networking services.

You must specify a /29 CIDR block from the 169.254.0.0/16 range (Option C): It is a requirement to specify a /29 CIDR block within the 169.254.0.0/16 range for setting up the network interfaces that facilitate BGP peering. This specific range allows for the necessary number of IP addresses to establish BGP sessions effectively between the transit gateway and on-premises or other virtual appliances.

References: These practices are in line with AWS guidelines for Transit Gateway Connect, which stipulate the use of specified CIDR blocks for internal networking and BGP configurations, ensuring seamless connectivity and routing management.
