SAMPLE QUESTION + SOLUTION EXPLANATION

NovaHarvest operates a smart farming analytics platform that processes drone imagery from isolated Compute Engine virtual machines running in private subnets. These VMs do not have external IP addresses, but they still need secure access to Google Cloud Storage APIs to upload crop health reports and retrieve sensor calibration files. What should the infrastructure team configure to allow these private VM instances to communicate with Cloud Storage services?

A. Configure Carrier Peering between the farm network and Google Cloud.

B. Configure VPC Network Peering between the production VPC and a Google-managed VPC.

C. Configure Shared VPC so all farming projects can access centralized networking resources.

D. Enable Private Google Access on the subnet hosting the Compute Engine instances.

Explanation:

A is incorrect because Carrier Peering is used to connect an enterprise network to Google through a supported service provider, typically for improved connectivity between an external network and Google services. The question is not asking how to connect an on-premises farm network to Google through a carrier. The Compute Engine virtual machines are already running inside private subnets in Google Cloud. Their problem is that they do not have external IP addresses but still need to reach Google APIs such as Cloud Storage. Carrier Peering does not solve that subnet-level requirement for private Google API access from Compute Engine instances.

B is incorrect because VPC Network Peering connects two VPC networks so resources in each network can communicate with each other using internal IP addresses. Cloud Storage is not a VM or workload running in a customer VPC network that you peer with in this way. Google Cloud Storage is a Google API service, and private Compute Engine instances need a private path to Google APIs and services, not VPC peering with a Google-managed VPC. VPC Network Peering is useful for private communication between VPC networks, but it is not the correct mechanism for allowing private VMs without external IP addresses to access Cloud Storage APIs.

C is incorrect because Shared VPC is used to centrally manage networking across multiple projects by letting service projects use subnets from a host project. It is useful when an organization wants centralized control of VPC networks, subnets, firewall rules, and related networking resources across projects. However, Shared VPC does not by itself allow Compute Engine instances without external IP addresses to access Google APIs such as Cloud Storage. Even in a Shared VPC design, the subnet that hosts the VM instances would still need the appropriate private access configuration for Google APIs.

D is correct because Private Google Access allows Compute Engine instances that have only internal IP addresses to reach Google APIs and services, including Cloud Storage, from a subnet. The VMs in this scenario are in private subnets and do not have external IP addresses, but they still need to upload reports to Cloud Storage and retrieve calibration files from Cloud Storage. Enabling Private Google Access on the subnet hosting those instances is the intended Google Cloud configuration for this requirement. It lets the instances communicate with Google APIs and services without assigning external IP addresses to the VMs, preserving the private-subnet design while still allowing secure access to Cloud Storage.
