What kind of underlying mechanism does Transit Gateway Connect use to send traffic from the virtual private cloud (VPC) to the transit gateway?
Correct Answer:
D
✑ Transit Gateway Connect Specificity: AWS Transit Gateway Connect is a specific feature designed to streamline the integration of SD-WAN appliances and third- party virtual appliances into your Transit Gateway.expand_more It utilizes a specialized attachment type.exclamation
✑ BGP's Role: While Transit Gateway Connect attachments leverage BGP for dynamic routing, BGP itself is a routing protocol and not the core connectivity mechanism in this context.
✑ GRE Tunneling: GRE is a tunneling protocol commonly used with Transit Gateway Connect attachments to encapsulate traffic.
You are asked to find a solution to replace the existing VPC peering topology to have a higher bandwidth connection from Amazon Web Services (AWS) to the on-premises data center Which two solutions will satisfy the requirement? (Choose two.)
Correct Answer:
CD
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.

You are using Red Hat Ansible to change the FortiGate VM configuration.
What is the minimum number of files you must create and which file must you use to configure the target FortiGate IP address?
Correct Answer:
B
In using Red Hat Ansible for changing the configuration of a FortiGate VM, the minimum number of files you must create and the file to configure the target FortiGate IP address are:
* B.Create two files and use the hosts file.
✑ Ansible Playbook File (YAML):The playbook file, which is typically a YAML file, contains the desired states and tasks that Ansible will execute on the target hosts.
✑ Inventory File (Hosts):The inventory file, commonly namedhosts, is where you define the target machines, including the FortiGate VM's IP address. Ansible uses this file to determine on which machines to run the playbook.
By creating these two files, you will have the necessary components to configure Ansible for the deployment. The playbook contains the automation tasks, and the hosts file lists the machines where those tasks will be executed.
References:This structure is specified in the Ansible documentation, which details the use of playbooks and inventory files to manage and configure target systems.
Refer to the exhibit.
What could be the reason that the administrator cannot access the EC2 instance?
Correct Answer:
D
The reason the administrator cannot access the EC2 instance could be: D.The directory location of the .pem file is incorrect.
✑ SSH Key Location:When initiating an SSH connection to an AWS EC2 instance,
you must specify the private key file (.pem file) location that corresponds to the public key used when the instance was launched. The error "Warning: Identity file Staging-key.pem not accessible: No such file or directory" indicates that the SSH client cannot find the .pem file at the specified location.
✑ Correct File Path:The administrator needs to ensure that the path to theStaging- key.pemfile is correctly specified when running the SSH command. If the file is not in the current directory from which the command is executed, the full or relative path to the file must be provided.
References:This behavior is in line with standard SSH connection practices and AWS guidelines for accessing EC2 instances. It is a common issue that occurs when the private key file is not located in the directory from which the SSH command is being executed or the path provided is incorrect.
In an SD-WAN TGW Connect topology, which three initial steps are mandatory when routing traffic from a spoke VPC to a security VPC through a Transit Gateway? (Choose three.)
Correct Answer:
ABD
✑ Spoke VPC Routing: The 0.0.0.0/0 (default) route in the spoke VPC must point to the Transit Gateway attachment for traffic to reach other VPCs or external destinations.
✑ Security VPC Routing: Traffic from the security VPC needs to pass through the FortiGate for inspection and security controls. Therefore, the 0.0.0.0/0 route in the security VPC's TGW subnet routing table must point to the FortiGate's internal port.
✑ FortiGate Routing: The FortiGate's internal subnet must have its 0.0.0.0/0 route
configured to point to the Transit Gateway attachment, allowing traffic to be returned to other VPCs or reach the internet.
In an SD-WAN TGW Connect topology, when routing traffic from a spoke VPC to a security VPC through a Transit Gateway, the mandatory initial steps include:
✑ From the spoke VPC internal routing table, point 0.0.0.0/0 traffic to the TGW
(Option A):This step is crucial for ensuring that all traffic from the spoke VPC destined for external networks is directed through the Transit Gateway, allowing for centralized management and security inspection.
✑ From the security VPC TGW subnet routing table: point 0.0.0.0/0 traffic to the
FortiGate internal port (Option B):Routing all traffic from the TGW subnet in the security VPC to the FortiGate's internal port ensures that traffic is subjected to the necessary security policies and inspections provided by the FortiGate appliance before it proceeds to other destinations or returns to the spoke VPCs.
✑ From the security VPC FortiGate internal subnet routing table, point 0.0.0.0/0
traffic to the TGW (Option D):This configuration ensures that traffic returning from the security processes handled by the FortiGate is routed back through the Transit Gateway, maintaining the integrity of the secure transit path and ensuring proper routing back to the originating spoke or onward to the internet.
References:These steps align with best practices for implementing SD-WAN solutions in a cloud environment, ensuring that all traffic is appropriately routed through security appliances for necessary controls and monitoring, asdetailed in the Fortinet SD-WAN documentation and AWS Transit Gateway connectivity guidelines.
