Google Professional Cloud Network Engineer Question 216
Select 3Google Cloud PlatformYou are designing a network architecture that involves two Virtual Private Cloud (VPC) networks: one for your company's production environment and the other for your development environment. Both VPCs are in the same project but are in different regions. You need to enable private, low-latency communication between instances in these VPCs. Which steps must you take to correctly configure VPC Network Peering between these two VPCs?
- A
Create a VPC peering connection request in the production VPC and accept it in the development VPC.
- B
Ensure that there are no overlapping CIDR ranges between the two VPCs.
- C
Enable firewall rules to allow traffic between the two VPCs after the peering connection is established.
- D
Enable global dynamic routing for both VPC networks before creating the peering connection.
- E
Create a Cloud VPN connection between the two VPCs to enable communication.
Show answer and explanation
Correct answers: A, B, C
Explanation
VPC Network Peering allows internal IP communication across two VPC networks without requiring an external IP address or additional resources like a Cloud VPN. To set up peering, both VPCs must have non-overlapping IP ranges, and the peering request must be created in one VPC and accepted in the other. Additionally, firewall rules must be configured to allow traffic between the VPCs. Cloud VPN and global dynamic routing are not prerequisites for VPC Network Peering.
- A. Correct.
Correct: To establish VPC Network Peering, you must create a peering request in one VPC and accept it in the other VPC.
- B. Correct.
Correct: VPC Network Peering requires that the IP ranges of the two VPCs do not overlap.
- C. Correct.
Correct: After the VPC peering connection is established, you need to manually configure firewall rules to allow traffic between the two VPCs.
- D. Incorrect.
Incorrect: Global dynamic routing is not required for VPC Network Peering. It is primarily used for sharing routes across regions in specific scenarios, such as with Cloud VPN or Interconnect.
- E. Incorrect.
Incorrect: Cloud VPN is not necessary for VPC Network Peering. Peering natively enables private communication between VPCs without requiring a VPN.
