The answer is no, because Private Service Connect regional access is strictly limited to the region where the endpoint is created. A Private Service Connect endpoint is a regional resource, meaning it can only be reached by Compute Engine instances within the same region of the VPC. In this scenario, the endpoint in us-central1 is not accessible from europe-west1, as traffic would need to cross regional boundaries, which PSC does not allow for producer endpoints. On the Google Professional Cloud Network Engineer exam, this concept tests your understanding of PSC’s regional scope versus global VPC routing, and a common trap is assuming that global VPC peering or internal IP addresses automatically grant cross-region access. Remember that PSC endpoints are region-locked, not global like Cloud NAT or VPC networks. A simple memory tip: “PSC endpoints stay home—they don’t travel regions.”
PCNE Configuring network services Practice Question
This PCNE practice question tests your understanding of configuring network services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has a VPC with subnets in us-central1 and europe-west1. They create a Private Service Connect endpoint for a managed service in us-central1. Can Compute Engine instances in europe-west1 access the endpoint?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No, because the endpoint is only accessible from the same region.
Private Service Connect (PSC) endpoints are regional resources. An endpoint created in us-central1 is only accessible from Compute Engine instances within the same region (us-central1) of the VPC. Instances in europe-west1 cannot directly reach the endpoint because traffic would need to cross regional boundaries, which PSC does not support for producer endpoints. Option D correctly identifies this regional restriction.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Yes, if they use a global load balancer in front of the endpoint.
Why it's wrong here
A global load balancer cannot front-end a Private Service Connect endpoint; the endpoint itself is regional.
✗
No, unless the VPC is peered with another VPC that contains the endpoint.
Why it's wrong here
Peering does not change regionality; the endpoint remains regional.
✗
Yes, because the endpoint is accessible from any region in the VPC.
Why it's wrong here
Private Service Connect endpoints are regional, not global.
✓
No, because the endpoint is only accessible from the same region.
Why this is correct
Private Service Connect endpoints are regional; instances must be in the same region to access the endpoint.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a VPC is a global construct and therefore any resource within it is globally accessible, but Cisco tests the specific regional nature of Private Service Connect endpoints, which are not globally routable within the VPC without additional configuration.
Detailed technical explanation
How to think about this question
Private Service Connect uses a regional internal IP address (from the VPC subnet in us-central1) and a regional forwarding rule. The endpoint is implemented as a regional internal load balancer (ILB) that forwards to the producer's service. Under the hood, the forwarding rule only accepts traffic from sources within the same region because the ILB's backend service and health checks are scoped regionally. In real-world scenarios, if an application in europe-west1 needs to consume the managed service, you must create a separate PSC endpoint in europe-west1 or use a cross-region internal load balancer with appropriate routing, but the endpoint itself remains region-bound.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
