Google Professional Cloud Network Engineer Question 359
Select 3Google Cloud PlatformYour organization is currently using VPC firewall rules to manage network security but wants to transition to firewall policies for better scalability and centralized management. As the Cloud Network Engineer, you are tasked with implementing this migration. Which of the following steps should you take to correctly migrate from VPC firewall rules to hierarchical firewall policies while ensuring minimal service disruption?
- A
Analyze existing VPC firewall rules and group them into appropriate policies based on shared requirements.
- B
Delete all existing VPC firewall rules before creating new hierarchical firewall policies to avoid conflicts.
- C
Create hierarchical firewall policies at the organization or folder level and apply them to the appropriate resources.
- D
Test the new firewall policies in a staging environment to confirm their behavior before applying them to production.
- E
Use hierarchical firewall policies to replace all VPC firewall rules, as both cannot coexist in the same project.
Show answer and explanation
Correct answers: A, C, D
Explanation
Migrating from VPC firewall rules to hierarchical firewall policies requires careful planning and execution to avoid service disruptions. The correct steps include analyzing and grouping existing rules, creating and applying new policies at the organization or folder level, and testing them thoroughly in a staging environment. Deleting existing rules prematurely or assuming both mechanisms cannot coexist can lead to unnecessary complexity and operational risks.
- A. Correct.
Correct: Analyzing and grouping existing VPC firewall rules ensures the new policies are logically organized and aligned with the organization's security requirements.
- B. Incorrect.
Incorrect: Deleting all existing VPC firewall rules prematurely can cause service disruption. Firewall rules and policies can coexist during the migration phase.
- C. Correct.
Correct: Creating and applying hierarchical firewall policies at the organization or folder level enables centralized management and scalability.
- D. Correct.
Correct: Testing the new policies in a staging environment is critical to avoid misconfigurations and potential security risks in production.
- E. Incorrect.
Incorrect: VPC firewall rules and hierarchical firewall policies can coexist in the same project. This allows for a phased migration approach, minimizing disruptions.
