CompTIA Cloud+ (CV0-004)Cloud ArchitectureHard
A cloud administrator needs to implement a solution that allows multiple Virtual Private Clouds (VPCs) in different regions to communicate with each other and also connect to an on-premises data center through a single, centralized gateway. This solution aims to simplify network topology and management. Which networking component should be used?
- ATransit Gateway
- BInternet Gateway (IGW)
- CVPC Peering
- DVirtual Private Gateway (VPG)
Show answer & explanationAnswer & explanation
Correct answer: A. Transit Gateway
A Transit Gateway acts as a central hub for connecting multiple VPCs and on-premises networks, including cross-region connectivity, simplifying complex network topologies into a hub-and-spoke model.
Why the other options are wrong
- B. An Internet Gateway (IGW) provides internet access for a VPC and is not designed for private inter-VPC or on-premises connectivity.
- C. VPC Peering connects two VPCs directly, requiring a mesh of connections for multiple VPCs and not supporting on-premises connectivity through a single hub.
- D. A Virtual Private Gateway (VPG) is primarily used for connecting a single VPC to an on-premises network via VPN or Direct Connect, not for inter-VPC communication across multiple regions or as a central hub.
Transit Gateway
A Transit Gateway is a network transit hub that you can use to interconnect your Virtual Private Clouds (VPCs) and on-premises networks. It scales to thousands of VPCs, simplifies network management, and supports cross-region connectivity.
- Central network hub for VPCs and on-premises networks
- Simplifies complex network topologies (hub-and-spoke)
- Scales to thousands of VPCs
- Supports cross-region connectivity
- Reduces the need for many-to-many peering connections
Memory trick: Transit Gateway is the 'traffic control tower' for your sprawling cloud network, centralizing all connections.
