Pass the Fortinet Network Security Expert NSE7_CDS_AR-7.6 Questions and answers with ExamsMirror

The Fortinet documentation states: "An IGW in AWS is a VPC component that allows communication between instances in your VPC and the internet... AWS users with less experience may face connectivity issues if they create a new VPC, add EC2 instances to it, but forget that they need an IGW for internet connectivity."

According to theFortiOS 7.6 Azure Administration Guideand theCloud Security 7.4 Public Cloud Study Guide, the integration of FortiGate-VMs with an Azure Gateway Load Balancer (GWLB) requires specific network configurations to ensure packet transit:

IP Forwarding Requirement (Option A):By default, Azure Network Interfaces (NICs) drop any traffic that does not originate from or is not destined for the IP address assigned to that NIC. For a FortiGate to act as a "bump-in-the-wire" or transparent inspector, it must receive traffic destined for other IPs and forward it. This requires theIP Forwardingsetting to be explicitlyenabledon the FortiGate's network interfaces within the Azure portal. If this is disabled, the Azure fabric will discard the traffic being steered through the FortiGate HA cluster by the GWLB.

VXLAN Encapsulation:The Azure GWLB uses VXLAN to encapsulate traffic (adding a VXLAN header with a specific VNI) before sending it to the FortiGate. The FortiGate must terminate this VXLAN tunnel. While the VXLAN configuration is crucial, the underlying infrastructure check for IP Forwarding is the most common cause of traffic being blocked at the NIC level before the FortiOS stack can process the packet.

Why other options are incorrect:

Option B:If health probes fail, the GWLB will typically stop sending traffic to that specific instance. While this affects the HA cluster's availability, the question states traffic is not being routedcorrectlythrough the firewalls (implying an active flow issue), and the primary mechanism for allowing a VM to process third-party traffic in Azure is IP Forwarding.

Option C:NSGs are typically applied to the NIC or Subnet. While incorrect NSG rules can block traffic, "IP Forwarding" is a specific requirement for the FortiGate to function as a network appliance (NVA) regardless of the NSG state.

Option D:Azure GWLB supportscross-subscriptionand cross-tenant chaining. The consumer (protected VMs) and the provider (FortiGate HA cluster) do not need to be in the same subscription, provided the GWLB endpoint is correctly mapped.

Based on theFortiOS 7.6 Automation Guideand the provided documentation for Ansible workflows, the following structure is required for managing multiple FortiGate nodes:

Inventory File (The Target List):The inventory is a single file that defines the list of managed nodes. It specifies critical information such as hostnames, connection details, and specifically theIP addressesof the target devices. According to the study guide, this inventory is atext filethat lists all the systems you want to manage.

Playbook File (The Task List):You create and edit a separate file that acts as theplaybook. This file is written inYAML formatand contains the series of tasks that Ansible performs on the managed nodes to reach a desired state.

Minimum File Count:A basic Ansible workflow consists of exactlytwo files: one inventory file (text) and one playbook file (YAML). By listing the target IP address (e.g., 10.0.206.131) within the inventory text file, the administrator can manage the FortiGate device without needing individual files for every target.

Why other options are incorrect:

Option A & C:Creating a separate playbook or inventory file foreachtarget is inefficient and contradicts the core Ansible workflow, which uses a single inventory to manage multiple hosts.

Option B:While the playbook is a .yaml file, the study guide specifically defines the inventory (where IP addresses are configured) as atext filein the context of the basic workflow.

According to theFortiOS 7.6 AWS Administration Guideand theFortinet 7.4 Public Cloud Securitystudy materials regarding infrastructure as code (IaC) for cloud deployments:

JSON Format Limitations (Option B):The exhibit shows an AWS CloudFormation template inJSON(JavaScript Object Notation) format. JSON, by its official specification,does not support comments. There is no native syntax (like // or /* */) to include remarks that are ignored by the CloudFormation parser.

YAML Support:To add descriptive comments—such as instructing other regional administrators to update the AMI ID—the administrator must convert the template intoYAMLformat. YAML is a superset of JSON and specifically supports comments using the#character.

Best Practice for Multinational Deployments:For organizations operating across multiple AWS regions, using YAML is the recommended standard because it allows for inline documentation, making templates more maintainable and easier for different teams to understand regional requirements.

Why other options are incorrect:

Option A:Comments are part of the template file itself, not a parameter or flag within the aws cloudformation update-stack CLI command.

Option C:While # is the correct character for comments in YAML, it isinvalid syntax in JSONand would cause the CloudFormation stack creation to fail with a parsing error.

Option D:The AWSTemplateFormatVersion "2010-09-09" is currently the only valid version for CloudFormation templates; updating it does not add JSON comment support.

Based on theFortiCNAPP (formerly Lacework) Cloud Securitydocumentation regarding Attack Path Analysis and Explorer functionality:

Attack Path Generation (Option A):In FortiCNAPP, an "Attack Path" is a visualized sequence of potential exploit steps that an external attacker could take to reach a sensitive resource. For the platform to generate and display an attack path, the target resource must beexternally reachable.

Evidence in the Exhibit:* The exhibit shows a list of EC2 and GCP instances.

The first two results (Resource IDs i-0d2d... and i-0e29...) have values populated in thePublic IP Addressescolumn (44.197.... and 3.226....). Consequently, these are the only two resources showing a value of1in theAttack Pathscolumn.

The remaining resources in the list do not have public IP addresses listed in the exhibit's view, and as a result, their Attack Paths count is0. This confirms that FortiCNAPP specifically calculates these paths for resources that have a direct entry point from the internet via a public IP.

Contextual Risk Assessment:FortiCNAPP prioritizes attack path analysis for internet-exposed assets because they represent the highest immediate risk. While internal resources may have vulnerabilities, the lack of a public-facing network interface means there is no direct external "path" to visualize in this specific Explorer view.

Based on theFortinet Cloud Security 7.4documentation and theFortiCASB Administration Guide, secur5ing a multi6cloud environment requires specialized tools for Software-as-a-Service (SaaS) visibility:

SaaS Visibility and Protection (Option B):FortiCASB (Cloud Access Security Broker) is a cloud-native service designed specifically to provideinsight into users and datastored within major SaaS applications like Office 365, Google Drive, and Salesforce.

Key Capabilities:

Data Discovery:It allows administrators to scan and identify sensitive data (PII, PCI, etc.) stored within SaaS platforms to prevent data leakage.

User Behavior Monitoring:It tracks user activities and alerts on anomalous behavior, such as logins from suspicious locations or excessive file downloads, to ensuresecure access.

Threat Protection:It integrates with FortiGuard to scan files within the cloud for malware, providing a layer of security that traditional network firewalls cannot reach once the data is inside the SaaS provider's infrastructure.

Why other options are incorrect:

Option A:FortiSandbox is used for advanced threat detection by executing suspicious files in a safe environment; it does not provide user/data management for SaaS applications.

Option C:FortiWeb is a Web Application Firewall (WAF) designed to protect web applications and APIs hosted on-premises or in the cloud from attacks like SQL injection; it is not a SaaS security broker.

Option D:FortiSIEM is a security information and event management solution used for cross-infrastructure logging and correlation; while it can ingest logs from SaaS, it does not provide the native data-level insights or direct access controls that FortiCASB offers.
