NSE7_PBC-7.2 Exam Dumps - Fortinet NSE 7 - Public Cloud Security 7.2

For automating the process of adding new spoke VPCs in a transit VPC architecture within Amazon Web Services (AWS), the two relevant features are:

• AWS Transit Gateway (Option C):This service is crucial for managing connectivity between VPCs and other networks without routing traffic through the public internet. It acts as a hub that controls how traffic is routed among all the connected networks, which simplifies network management and minimizes latency.
• Amazon CloudWatch (Option D):CloudWatch provides monitoring and observability services that are essential for managing the health and performance of the AWS infrastructure, including Transit Gateways. It allows administrators to set alarms and react to changes in AWS resources, which is vital for the dynamic addition and integration of new spoke VPCs into the transit VPC architecture.

References:AWS official documentation on Transit Gateways and CloudWatch details these services' roles in enhancing network management and monitoring, essential for effective and automated transit VPC operations.

B. FortiGate A and FortiGate B are two independent devices. This means that they are not part of a cluster or a high availability group, and they do not share the same configuration or state information. They are configured as standalone FortiGates with standalone configuration synchronization enabled1. This feature allows them to synchronize most of their configuration settings with each other, except for some settings that identify the FortiGate to the network, such as the hostname1. D. It does not synchronize the FortiGate hostname. This is one of the settings that are excluded from the standalone configuration synchronization, as mentioned above. The hostname is a unique identifier for each FortiGate device, and it should not be changed by the synchronization process1.

The other options are incorrect because:

• FortiGate-VM instances are not scaled out automatically according to predefined workload levels. This is a feature of the auto scaling solution for FortiGate-VM on Azure, which requires a different deployment and configuration than the one shown in the exhibit2. The exhibit shows a static deployment of two FortiGate-VM instances behind an Azure load balancer, which does not support auto scaling.
• By default, FortiGate does not use FGCP. FGCP stands for FortiGate Clustering Protocol, which is used to synchronize configuration and state information between FortiGate devices in a cluster or a high availability group3. However, the exhibit shows that the FortiGates are not in a cluster or a high availability group, and they use standalone configuration synchronization instead of FGCP.

 The Azure client secret is a one-time value that is only visible when it is created. If the administrator loses or forgets the client secret, they cannot retrieve it from the Azure portal. However, they can create a new client secret and use it to configure Terraform. To create a new client secret, they need to follow these steps12:

• Sign in to the Azure portal and navigate to the Azure Active Directory service.
• Select the application name under the App Registrations.
• Select Certificates & Secrets > New client secret to create a new client secret.
• Add a description and an expiration date for the client secret and select Add.
• Copy the value of the new client secret immediately as it will not be shown again.

The correct answer is D. CloudWatch and S3.

According to the GitHub repository for the Fortinet aws-lambda-tgw script1, this function requires the following AWS services:

• CloudWatch: A monitoring and observability service that collects and processes events from various AWS resources, including Transit Gateway attachments and route tables.
• S3: A scalable object storage service that can store the configuration files and logs generated by the Lambda function.

By using the Fortinet aws-lambda-tgw script, you can automate the creation and configuration of Transit Gateway Connect attachments for your FortiGate devices.This can help you save time and avoid errors when adding more spoke VPCs to an existing hub and spoke topology1.

The other AWS services mentioned in the options are not required for this task. GuardDuty is a threat detection service that monitors for malicious and unauthorized behavior to help protect AWS accounts and workloads. WAF is a web application firewall that helps protect web applications from common web exploits. Inspector is a security assessment service that helps improve the security and compliance of applications deployed on AWS. DynamoDB is a fast and flexible NoSQL database service that can store various types of data.

• Transit Gateway Connect Specificity: AWS Transit Gateway Connect is a specific feature designed to streamline the integration of SD-WAN appliances and third-party virtual appliances into your Transit Gateway.expand_more It utilizes a specialized attachment type.exclamation
• BGP's Role: While Transit Gateway Connect attachments leverage BGP for dynamic routing, BGP itself is a routing protocol and not the core connectivity mechanism in this context.
• GRE Tunneling: GRE is a tunneling protocol commonly used with Transit Gateway Connect attachments to encapsulate traffic.

The error message indicates that the Connect attachment is already associated with another transit gateway route table. You cannot associate the same attachment with more than one route table. However, you can propagate the same attachment to multiple route tables. Therefore, to fulfill your requirement of configuring a second route table for east-west traffic inspection between two VPCs, you need to create a propagation with the Connect attachment in the second route table. This will allow the second route table to learn the routes from the Connect attachment and forward the traffic to the securityVPC1. You also need to associate the second route table with the Transport attachment, which is the transit gateway attachment for the security VPC1.

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.

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.

The two best connection solutions available between your company headquarters, branch sites, and the Azure vWAN hub are A. ExpressRoute and E. VPN Gateway.

According to the Azure documentation for Virtual WAN, ExpressRoute and VPN Gateway are two of the supported connectivity options for connecting your on-premises sites and Azure virtual networks to the Azure vWAN hub1. These options provide secure, reliable, and high-performance connectivity for your network traffic.

ExpressRoute is a service that lets you create private connections between your on-premises sites and Azure.ExpressRoute connections do not go over the public internet, and offer more reliability, faster speeds, lower latencies, and higher security than typical connections over the internet2.

VPN Gateway is a service that lets you create encrypted connections between your on-premises sites and Azure over the internet using IPsec/IKE protocols.VPN Gateway also supports point-to-site VPN connections for individual clients using OpenVPN or IKEv2 protocols3.

The other options are incorrect because:

• GRE tunnels are not a supported connectivity option for Azure vWAN. GRE is a protocol that encapsulates packets for tunneling purposes.GRE tunnels are established between the connect attachment and your appliance in Azure vWAN4.
• SSL VPN connections are not a supported connectivity option for Azure vWAN. SSL VPN is a type of VPN that uses the Secure Sockets Layer (SSL) protocol to secure the connection between a client and a server.SSL VPN is not compatible with the Azure vWAN hub5.
• An L2TP connection is not a supported connectivity option for Azure vWAN. L2TP is a protocol that creates a tunnel between two endpoints at the data link layer (Layer 2) of the OSI model.L2TP is not compatible with the Azure vWAN hub.

To keep track of sensitive data files located in AWS S3 buckets and protect them from malware, the administrator should use:

C.FortiCNP DLP policies.

• Data Loss Prevention (DLP):DLP policies are designed to detect and prevent unauthorized access or sharing of sensitive data. In the context of AWS S3, DLP policies can be used to scan for sensitive information stored in S3 objects and enforce protective measures to prevent data exfiltration or compromise.
• FortiCNP Integration:FortiCNP is Fortinet’s cloud-native protection platform that offers security and compliance solutions across cloud environments. By applying DLP policies within FortiCNP, the administrator can ensure sensitive data within S3 is monitored and protected consistently.

References:Fortinet's FortiCNP documentation provides information on implementing DLP policies within cloud environments, highlighting the capabilities for protecting sensitive data within cloud storage services like AWS S3.

• Spoke VPC Routing: The 0.0.0.0/0 (default) route in the spoke VPC must point to the Transit Gateway attachment for traffic to reach other VPCs or external destinations.
• Security VPC Routing: Traffic from the security VPC needs to pass through the FortiGate for inspection and security controls. Therefore, the 0.0.0.0/0 route in the security VPC's TGW subnet routing table must point to the FortiGate's internal port.
• FortiGate Routing: The FortiGate's internal subnet must have its 0.0.0.0/0 route configured to point to the Transit Gateway attachment, allowing traffic to be returned to other VPCs or reach the internet.

In an SD-WAN TGW Connect topology, when routing traffic from a spoke VPC to a security VPC through a Transit Gateway, the mandatory initial steps include:

• From the spoke VPC internal routing table, point 0.0.0.0/0 traffic to the TGW (Option A):This step is crucial for ensuring that all traffic from the spoke VPC destined for external networks is directed through the Transit Gateway, allowing for centralized management and security inspection.
• From the security VPC TGW subnet routing table: point 0.0.0.0/0 traffic to the FortiGate internal port (Option B):Routing all traffic from the TGW subnet in the security VPC to the FortiGate's internal port ensures that traffic is subjected to the necessary security policies and inspections provided by the FortiGate appliance before it proceeds to other destinations or returns to the spoke VPCs.
• From the security VPC FortiGate internal subnet routing table, point 0.0.0.0/0 traffic to the TGW (Option D):This configuration ensures that traffic returning from the security processes handled by the FortiGate is routed back through the Transit Gateway, maintaining the integrity of the secure transit path and ensuring proper routing back to the originating spoke or onward to the internet.

References:These steps align with best practices for implementing SD-WAN solutions in a cloud environment, ensuring that all traffic is appropriately routed through security appliances for necessary controls and monitoring, asdetailed in the Fortinet SD-WAN documentation and AWS Transit Gateway connectivity guidelines.

Immutable infrastructure is a DevOps approach that emphasizes the creation of disposable resources instead of modifying existing ones1. This approach helps to achieve stability, consistency, and predictability in IT operations by reducing the risk of configuration drift and eliminating stateful components1.

One way to implement immutable infrastructure is to use a blue-green deployment strategy, which runs two live environments for configuration changes2. The blue environment is the current production environment, while the green environment is the new version of the application or service. When the green environment is ready, the traffic is switched from blue to green, and the blue environment is destroyed or kept as a backup2. This way, there is no need to update or patch the existing infrastructure, but rather replace it with a new one.

When using an AWS CloudFormation template to add a new spoke to an existing transit VPC environment, the necessary components are:

• The BGPASN value used for the transit VPC (Option C):BGP Autonomous System Number (ASN) is required for setting up BGP routing between the transit VPC and the new spoke. This number uniquely identifies the system in BGP routing and is crucial for correct routing and avoiding routing conflicts.
• The tag value of the spoke (Option D):Tags in AWS are used to identify and manage resources. The tag value assigned to a spoke VPC helps in organizing, managing, and locating the VPC within the larger AWS environment. Tags are essential for automation scripts and policies that depend on specific identifiers to apply configurations or rules.

References:AWS CloudFormation and AWS Transit Gateway documentation provide guidance on the use of BGPASN and tags for managing and automating VPC deployments effectively.

The correct answer is B and D. A transit gateway with an attachment and a transit VPC support east-west traffic inspection within the AWS cloud by the FortiGate VM.

According to the Fortinet documentation for Public Cloud Security, a transit gateway is a network transit hub that connects VPCs and on-premises networks. A transit gateway attachment is a resource that connects a VPC or VPN to a transit gateway.By using a transit gateway with an attachment, you can route traffic from your spoke VPCs to your security VPC, where the FortiGate VM can inspect the traffic1.

A transit VPC is a VPC that serves as a global network transit center for connecting multiple VPCs, remote networks, and virtual private networks (VPNs).By using a transit VPC, you can deploy the FortiGate VM as a virtual appliance that provides network security and threat prevention for your VPCs2.

The other options are incorrect because:

• A NAT gateway with an EIP is a service that enables instances in a private subnet to connect to the internet or other AWS services, but prevents the internet from initiating a connection with those instances.A NAT gateway with an EIP does not support east-west traffic inspection within the AWS cloud by the FortiGate VM3.
• An Internet gateway with an EIP is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet.An Internet gateway with an EIP does not support east-west traffic inspection within the AWS cloud by the FortiGate VM4.
