Which of the following components can be used to consolidate and forward inbound internet traffic to multiple cloud environments though a single firewall?
Correct Answer: A
A transit gateway is a network transit hub that can be used to interconnect virtual private clouds (VPCs) and on-premises networks. A transit gateway can consolidate and forward inbound internet traffic to multiple cloud environments through a single firewall by offering the following features:
* Attachments that can connect one or more VPCs, a Connect SD-WAN/third-party network appliance, an AWS Direct Connect gateway, a peering connection with another transit gateway, or a VPN connection to a transit gateway.
* Transit gateway route table that can include dynamic and static routes that decide the next hop based on the destination IP address of the packet.
* Associations and route propagation that can link each attachment with a route table and dynamically propagate routes to or from a transit gateway route table.
