Pass the Fortinet NSE 7 Network Security Architect NSE7_PBC-7.2 Questions and answers with CertsForce

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.

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.

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.

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 security VPC1. You also need to associate the second route table with the Transport attachment, which is the transit gateway attachment for the security VPC1.

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.

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.

For configuring the failover settings on a FortiGate active-passive SDN connector solution in Microsoft Azure, the two mandatory settings required after the initial deployment are:

A. Subscription-id

D. Resource group name

Subscription ID: This is a unique identifier for your Azure subscription under which all resources are created and billed. FortiGate needs this to interact with the Azure resources associated with that subscription.

Resource Group Name: A resource group in Azure is a container that holds related resources for an Azure solution. The SDN connector requires the resource group name to correctly identify and manage the resources it should control, especially in a failover scenario.

References: The requirement for these specific details is found in Azure's best practices for resource management and Fortinet's documentation on deploying and configuring FortiGate appliances in Azure environments.
