Google Associate Cloud EngineerPlanning and configuring a cloud solutionEasy
A financial institution is planning to migrate its highly regulated on-premises applications to Google Cloud. These applications require strict network isolation, private IP communication between services, and the ability to control all inbound and outbound traffic with granular firewall rules. Which Google Cloud networking concept is fundamental to achieving these requirements?
- ACloud Load Balancing
- BVPC Network
- CShared VPC
- DVPC Service Controls
Show answer & explanationAnswer & explanation
Correct answer: B. VPC Network
A VPC Network is a fundamental global networking resource in Google Cloud that provides isolated, private IP spaces for resources, enabling granular firewall rules and private communication between services, essential for strict network isolation.
Why the other options are wrong
- A. Cloud Load Balancing distributes traffic to instances, but it doesn't provide the underlying network isolation or granular firewall control itself.
- C. Shared VPC allows multiple projects to use a common VPC network but is built on top of the fundamental VPC Network concept.
- D. VPC Service Controls protect sensitive data by creating security perimeters around Google Cloud services, which is a security layer on top of a VPC, not the fundamental network isolation.
VPC Network
A Virtual Private Cloud (VPC) Network is a global, private network in Google Cloud that provides IP address space, routing, and firewall rules for your cloud resources, enabling secure and isolated communication.
- Globally distributed private network
- Provides IP address space, routes, and firewalls
- Enables secure and isolated resource communication
