Google Professional Cloud Network Engineer Question 278
Single answerGoogle Cloud PlatformYour company is expanding its global presence and needs to connect multiple Virtual Private Cloud (VPC) networks across different regions while maintaining centralized control and simplifying security policies. Which VPC topology is most suitable for this scenario?
- A
Star topology
- B
Hub-and-spoke topology
- C
Mesh topology
- D
Flat topology
Show answer and explanation
Correct answer: B
Explanation
Hub-and-spoke topology is the most suitable choice for connecting multiple VPCs across regions while maintaining centralized control and simplifying security policies. The hub VPC acts as the central point for routing and security, ensuring scalability and manageability for large-scale global deployments.
- A. Incorrect.
Star topology involves a single central VPC to which all other VPCs are directly connected. While this may work for small-scale setups, it doesn't provide the centralized control or scalability needed for a large, global infrastructure.
- B. Correct.
Hub-and-spoke topology uses a central hub VPC to connect multiple spoke VPCs. This provides centralized control, simplifies management, and is scalable, making it ideal for global and multi-regional deployments.
- C. Incorrect.
Mesh topology involves direct connections between all VPCs, which can quickly become complex and unmanageable as the number of VPCs increases. This is not suitable for scenarios requiring centralized control.
- D. Incorrect.
Flat topology is not a recognized or practical VPC topology in Google Cloud for connecting multiple networks. It is not applicable for this scenario.
