Considering the situation where the administrator is unable to access the FortiGate VM using its public IP address and no traffic is reaching the FortiGate's external interface, the administrator should check:

D.Check the inbound network security group rules.

• Network Security Group Rules:AWS uses security groups as a virtual firewall that controls inbound and outbound traffic to AWS resources such as EC2 instances. If the FortiGate VM’s public interface is not receiving HTTPS or SSH traffic, it's likely because the inbound security group rules associated with that interface are not allowing access on the necessary ports (HTTPS - port 443, SSH - port 22).
• Troubleshooting:The administrator should verify that the security group rules for the FortiGate VM’s network interface allow inbound traffic on the specific ports used for management access. If these rules are absent or misconfigured, the intended traffic will be blocked, resulting in the inability to connect.

References:The role of security groups in network traffic management is a core concept in AWS and is outlined in AWS documentation. Checking security group rules is a standard troubleshooting step when dealing with connectivity issues to AWS resources.

In this scenario, the issue is caused by the Azure service principle account nothaving a contributor role. This is required for the FortiGate HA floating IP to work properly. Without this role, the new primary device will not have the previous primary device floating IP address after failover. References: Fortinet Public Cloud Security knowledge source documents or study guide.

• Integration and Functionality:FortiCASB integrates seamlessly with major SaaS platforms, providing a centralized management interface that allows for comprehensive analysis and real-time protection measures. This integration ensures that organizations can maintain control over their data across various cloud services, enhancing the overall security posture in a multicloud environment.

References:Fortinet’s official documentation on FortiCASB details its functionalities and integration capabilities with SaaS applications, highlighting its role in providing enhanced security measures for cloud-based services.

The correct answer is C. Use FortiWebCloud.

FortiWebCloud is a SaaS cloud-based web application firewall (WAF) that protects public cloud hosted web applications from the OWASP Top 10, zero day threats, and other application layer attacks1.FortiWebCloud also includes robust features such as API discovery and protection, bot mitigation, threat analytics, and advanced reporting2.FortiWebCloud supports multiple regions across the world, and you can choose the region that is closest to your applications to minimize traffic cost3.

The other options are incorrect because:

• FortiADC is an application delivery controller that provides load balancing, acceleration, and security for web applications.It is not a dedicated WAF solution and does not offer the same level of protection as FortiWebCloud4.
• FortiCNP is a cloud-native platform that provides security and visibility for containerized applications.It is not a WAF solution and does not protect web applications from the OWASP Top 10 vulnerabilities5.
• FortiGate is a next-generation firewall (NGFW) that provides network security and threat prevention. It is not a WAF solution and doesnot offer the same level of protection as FortiWebCloud for web applications.It also requires additional configuration and management to deploy in the public cloud6.

Terraform manages and tracks the state of infrastructure resources through a file known asterraform.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:Theterraform.tfstatefile 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 theterraform.tfstatefile is used to keep track of the infrastructure Terraform is managing.

The variables.tf file shows that the FortiGate VM will be deployed in the eu-West-Ia region with private and public subnets. The region variable is set to “eu-west-1” and the availability_zone variable is set to “eu-west-1a”. The vpc_id variable is set to “vpc-0e9d6a6f” and the subnets variable is set to a list of two subnet IDs: “subnet-0f9d6a6f” and “subnet-1f9d6a6f”. The license_type variable is set to “on-demand” and the ami_id variable is set to “ami-0e9d6a6f”.

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

According to the AWS documentation for Transit Gateway, a Transit Gateway is a network transit hub that connects VPCs and on-premises networks. To route traffic from Linux instances to the TGW, you need to do the following steps:

• In the TGW route table, associate two attachments. An attachment is a resource that connects a VPC or VPN to a Transit Gateway. By associating the attachments to the TGW route table, you enable the TGW to route traffic between the VPCs and the VPN.
• In the main subnet routing table in VPC A and B, add a new route with destination 0_0.0.0/0, next hop TGW. This route directs all traffic from the Linux instances to the TGW, which can then forward it to the appropriate destination based on the TGW route table.

The other options are incorrect because:

• In the TGW route table, adding route propagation to 192.168.0 0/16 is not necessary, as this is already the default route for the TGW. Route propagation allows you to automatically propagate routes from your VPC or VPN to your TGW route table.
• In the main subnet routing table in VPC A and B, adding a new route with destination 0_0.0.0/0, next hop Internet gateway (IGW) is not correct, as this would bypass the TGW and send all traffic directly to the internet. An IGW is a VPC component that enables communication between instances in your VPC and the internet.

[Transit Gateways - Amazon Virtual Private Cloud]

• 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.

The reason the administrator cannot access the EC2 instance could be:

D.The directory location of the .pem file is incorrect.

• SSH Key Location:When initiating an SSH connection to an AWS EC2 instance, you must specify the private key file (.pem file) location that corresponds to the public key used when the instance was launched. The error "Warning: Identity file Staging-key.pem not accessible: No such file or directory" indicates that the SSH client cannot find the .pem file at the specified location.
• Correct File Path:The administrator needs to ensure that the path to theStaging-key.pemfile is correctly specified when running the SSH command. If the file is not in the current directory from which the command is executed, the full or relative path to the file must be provided.

References:This behavior is in line with standard SSH connection practices and AWS guidelines for accessing EC2 instances. It is a common issue that occurs when the private key file is not located in the directory from which the SSH command is being executed or the path provided is incorrect.

The correct answer is C and D. FortiGate NGFW can inspect north-south container traffic with label aware policies and FortiGate NGFW and FortiSandbox can be used to secure container traffic.

According to the Fortinet documentation for container security1, FortiGate NGFW can provide the following benefits for securing container infrastructure:

• It can inspect north-south traffic between containers and external networks using label aware policies, which allow for dynamic policy enforcement based on Kubernetes labels and metadata.
• It can integrate with FortiSandbox to provide advanced threat protection for container traffic, by sending suspicious files or URLs to a cloud-based sandbox for analysis and detection.
• It can leverage FortiGuard Security Services to provide real-time threat intelligence and updates for container traffic, such as antivirus, web filtering, IPS, and application control.

The other options are incorrect because:

• FortiGate NGFW cannot be placed between each application container for north-south traffic inspection, as this would create unnecessary complexity and overhead. Instead, FortiGate NGFW can be deployed at the edge of the container network or as a sidecar proxy to inspect traffic at the ingress and egress points.
• FortiGate NGFW cannot connect to the worker node and protect the container, as this would not provide sufficient visibility and control over the container traffic. Instead, FortiGate NGFW can leverage the native Kubernetes APIs and services to monitor and secure the container traffic.

• A is correct because in this deployment, the passive FortiGate issues API calls to Azure to update the routing table and the public IP address of the active FortiGate123. This way, the traffic is redirected to the new active FortiGate after a failover.
• B is incorrect because the vdom-exception command is used to exclude specific VDOMs from being synchronized in an HA cluster.This command is not related to this deployment scenario.
• C is incorrect because Microsoft Azure does provide an SLA for API calls. According to the Azure Service Level Agreements, the API Management service has a monthly uptime percentage of at least 99.9% for the standard tier and higher.
• D is correct because by default, the configuration is not synchronized between the primary and secondary devices in this deployment. The administrator needs to manually enable configuration synchronization on both devices123. Alternatively, the administrator can use FortiManager to manage and synchronize the configuration of both devices4.

• 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.

Confirming to delete all the resources in Terraform will have the following impact:

D.It destroys all the resources in the state file.

• Terraform State File Role:Theterraform.tfstatefile contains a real-time mapping of the resources that Terraform manages, including their current configuration and relationships. This file tracks the actual state of resources provisioned by Terraform.
• Impact of Destruction:When Terraform prompts for confirmation to destroy resources, and 'yes' is entered, Terraform reads the state file and systematically removes all the resources that are managed as part of that state. This is not limited to a specific .tfvars file, IAM user, or resource group—it is a global action that affects all resources tracked by the state file associated with the current Terraform workspace and configuration.

References:The function of theterraform.tfstatefile and the impact of resource destruction are detailed in Terraform's official documentation. This behavior is fundamental to how Terraform manages infrastructure as code.
