A company has multiple VPCs in different cloud accounts that need to communicate with each other. They also need to enforce centralized security policies and simplify network management. Which cloud networking service should they use to create a hub-and-spoke topology?
A transit gateway acts as a central hub to connect multiple virtual networks and on-premises networks, simplifying management and enabling centralized security policies.
Why this answer
A cloud transit gateway allows you to connect multiple VPCs and on-premises networks through a central hub, simplifying management and enabling centralized security policies. Virtual network peering is point-to-point and does not scale well for many VPCs.
