NSE7_PBC-7.2 Exam Dumps - Fortinet Certification Questions and Answers

The correct answer is C and D. Use a transit VPC with hub and spoke topology to create multiple VPN connections to the on-premises data center. Use the transit gateway attachment with VPN option to create multiple VPN connections to the on-premises data center.

According to the Fortinet documentation for Public Cloud Security, 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). A transit VPC can use a hub and spoke topology to create multiple VPN connections to the on-premises data center, using the FortiGate VM as a virtual appliance that provides network security and threat prevention.A transit VPC can also leverage Equal-Cost Multi-Path (ECMP) routing to achieve higher bandwidth and load balancing across multiple VPN tunnels1.

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. You can use the transit gateway attachment with VPN option to create multiple VPN connections to the on-premises data center, using the FortiGate VM as a virtual appliance that provides network security and threat prevention.A transit gateway attachment with VPN option can also leverage ECMP routing to achieve higher bandwidth and load balancing across multiple VPN tunnels2.

The other options are incorrect because:

• Using ECMP and VPN to achieve higher bandwidth is not a complete solution, as it does not specify how to replace the existing VPC peering topology or how to connect the AWS VPCs to the on-premises data center.
• Using transit VPC to build multiple VPC connections to the on-premises data center is not a correct solution, as it does not specify how to use a hub and spoke topology or how to leverage ECMP routing for higher bandwidth.

To configure a FortiGate VM to add to FortiCNP, you need to perform three steps on FortiGate:

• Enable send logs in FortiGate to allow FortiCNP to receive the IPS logs from FortiGate.
• Create an SSL/SSH inspection profile on FortiGate to inspect the encrypted traffic and apply IPS protection.
• Create an IPS sensor and a firewall policy on FortiGate to enable IPS detection and prevention for the 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.

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.
