What is the bandwidth limitation of an Amazon Web Services (AWS) transit gateway VPC attachment?

You have been tasked with deploying FortiGate VMs in a highly available topology on the Amazon Web Services (AWS) cloud. The requirements for your deployment are as follows:
* You must deploy two FortiGate VMs in a single virtual private cloud (VPC), with an external elastic load balancer which will distribute ingress traffic from the internet to both FortiGate VMs in an active-active topology.
* Each FortiGate VM must have two elastic network interfaces: one will connect to a public subnet and other will connect to a private subnet.
* To maintain high availability, you must deploy the FortiGate VMs in two different availability zones.
How many public and private subnets will you need to configure within the VPC?

You are deploying Amazon Web Services (AWS) GuardDuty to monitor malicious or unauthorized behaviors related to AWS resources. You will also use the Fortinet aws-lambda-guardduty script to translate feeds from AWS GuardDuty findings into a list of malicious IP addresses. FortiGate can then consume this list as an external threat feed.
Which Amazon AWS services must you subscribe to in order to use this feature?

Refer to the exhibit.

The exhibit shows a topology where multiple connections from clients to the same FortiGate-VM instance, regardless of the protocol being used, are required.
