Google Cloud Professional Cloud Security Engineer Practice Exam

To follow Google-recommended best practices while deploying a CI/CD pipeline, what action should be taken regarding default networks?

1. Enable an organization policy to skip default network creation

2. Implement custom network rules for each project

3. Use only Google’s recommended default networks

4. Create default subnets in each region manually

The correct answer is: Enable an organization policy to skip default network creation

To align with Google-recommended best practices for deploying a CI/CD pipeline, enabling an organization policy to skip the creation of default networks is a significant step. Default networks in Google Cloud are automatically created for each project and can introduce unnecessary complexity and potential security risks. By disabling the automatic creation of these networks, you ensure that only the networks you explicitly define and configure are in use. This approach fosters a more controlled and secure environment because it encourages teams to design custom networks tailored to their applications' specific requirements. Custom networks allow for better segregation of resources, improved security postures, and more granular control over firewall rules and access management. By proactively managing network configurations rather than relying on default settings, organizations can better enforce security policies and meet compliance requirements. Turning to the other options, while implementing custom network rules can offer enhanced security, without first disabling the default networks, these rules could still conflict with or overlook the default configurations. Using Google’s recommended default networks could lead to vulnerabilities if the networks are not specifically tailored for an organization’s unique needs. Manually creating default subnets in each region could add unnecessary operational overhead and complexity, which contradicts the goal of maintaining a streamlined and secure infrastructure. Thus, enabling an organization policy to skip the creation of
