B . The default network ACL is configured to allow all traffic.This means that when you create a VPC, AWS automatically creates a default network ACL for that VPC, and associates it with all the subnets in the VPC1.By default, the default network ACL allows all inbound and outbound IPv4 traffic and, if applicable, IPv6 traffic1.You can modify the default network ACL, but you cannot delete it1. C. Network ACLs are stateless, and inbound and outbound rules are used for traffic filtering.This means that network ACLs do not keep track of the traffic that they allow or deny, and they evaluate each packet separately1.Therefore, you need to create both inbound and outbound rules for each type of traffic that you want to allow or deny1.For example, if you want to allow SSH traffic from a specific IP address to your subnet, you need to create an inbound rule to allow TCP port 22 from that IP address, and an outbound rule to allow TCP port 1024-65535 (the ephemeral ports) to that IP address2.

The other options are incorrect because:

You can use network ACL and security group at the same time.Network ACL and security group are two different types of security layers for your VPC that can work together to control traffic3.Network ACL acts as a firewall for your subnets, while security group acts as a firewall for your instances3. You can use both of them to create a more granular and effective security policy for your VPC.

Network ACLs are not tied to an instance.Network ACLs are associated with subnets, not instances1.This means that network ACLs apply to all the instances in the subnets that they are associated with1. You cannot associate a network ACL with a specific instance.However, you can associate a security group with a specific instance or multiple instances3.

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 variables.tf file shows that the FortiGate VM will be deployed in the eu-West-Ia region with private and public subnets. The region variable is set to ''eu-west-1'' and the availability_zone variable is set to ''eu-west-1a''. The vpc_id variable is set to ''vpc-0e9d6a6f'' and the subnets variable is set to a list of two subnet IDs: ''subnet-0f9d6a6f'' and ''subnet-1f9d6a6f''. The license_type variable is set to ''on-demand'' and the ami_id variable is set to ''ami-0e9d6a6f''.

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.
