You work at a mid-sized food delivery startup. Your company is mid-way on their journey of migrating all of their applications to GCP. For now, some of the resources are present on-premises and the rest are on GCP. The VMs on Compute Engine communicate with on-premise servers through Cloud VPN over private IP addresses. A database server running on-premises is used by several applications running on GCP. You want to make the GCP applications don’t need to do any configuration change in case the IP address of the on-premise database changes. What should you do? A. Configure Cloud NAT for all subnets of your VPC, which will be used by VMs for egress traffic. B. Create a private zone on Cloud DNS. Configure the applications using the DNS name. C. Store the IP of the database as a custom metadata entry inside each instance, and query the metadata server. D. Write code in applications to query the Compute Engine internal DNS to retrieve the IP of the database. Explanation: A is incorrect because Cloud NAT is used to provide internet access to resources and that’s not the requirement here. Configuring Cloud NAT for all subnets of the VPC would only handle egress traffic from the VMs. It does not address the issue of the on-premise database IP address changing and the GCP applications needing to be reconfigured. B is correct because: – Cloud DNS forwarding zones let you configure target name servers for specific private zones. Using a forwarding zone is one way to implement outbound DNS forwarding from your VPC network. – In our case, it is mentioned that we have a hybrid, VPN, VPC, etc and the only thing we need is not to be dependent on IP change. From Google documentation private zone on Cloud DNS (Option-B) will help us to solve this issue. – Creating a private zone on Cloud DNS and configuring the applications to use the DNS name allows for dynamic resolution of the database IP address. By using the DNS name instead of the IP address directly, any changes to the IP address can be managed by updating the DNS record, without requiring any configuration changes in the GCP applications. C is incorrect because the custom metadata will need to be updated whenever the IP address of the database changes. Storing the IP of the database as a custom metadata entry inside each instance would still require the GCP applications to reference the metadata server and retrieve the IP. Any changes to the IP would still require updating the metadata entries and potentially updating the applications as well. D is incorrect because querying the Compute engine DNS does not help because the database server is on-premises. Writing code in applications to query the Compute Engine internal DNS to retrieve the IP of the database would still require manual changes to the applications if the IP address of the database changes. It does not provide a dynamic solution to handle changes in the database IP address. Tags: Google Cloud Associate Cloud EngineerIT & SoftwareIT Certification
