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 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 does not offer the same level of protection as FortiWebCloud for web applications. It also requires additional configuration and management to deploy in the public cloud6.

This is because the Linux1 EC2 instance is not accessible directly from the internet using its public IP address in AWS.

An internet gateway is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet. Without an internet gateway, the Linux1 EC2 instance cannot receive or send traffic to or from the internet, even if it has a public IP address assigned to it.

To fix this issue, you need to attach an internet gateway to the Spoke VPC A and configure a route table that directs internet-bound traffic to the internet gateway. You also need to ensure that the Linux1 EC2 instance has a security group that allows inbound and outbound traffic on the desired ports.

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.

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 Terraform documentation for installing Terraform on Linux1, you need to download a zip archive that contains a single binary file called terraform. You need to unzip the archive and move the binary file to a directory that is included in your system's PATH environment variable, such as /usr/local/bin.This way, you can run the terraform command from any directory without specifying the full path1.

If you do not move the binary file to the bin directory, you will get a command not found error when you try to run the terraform version command, as shown in the screenshot.To fix this error, you need to move the binary file to the bin directory or specify the full path of the binary file when running the command1.

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.

Based on the provided exhibit showing an active-passive FortiGate High Availability (HA) pair with external and internal Azure load balancers and without the use of an SDN connector, the administrator should implement a Probe IP address with two static routes (Option B).

Probe IP Address: Azure load balancers use a health probe to determine the health of the instances in the backend pool. The health probe ensures that the load balancer only directs traffic to the active (primary) FortiGate in an HA pair.

Two Static Routes: Given that this is an active-passive setup, static routing should be used to ensure deterministic traffic flow. Two static routes would be configured to ensure that traffic can flow to the active unit and be correctly routed to the protected subnets in failover scenarios.

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.
