- A
Enable VPC Service Controls around Cloud Run to connect it to the VPC
Why wrong: VPC Service Controls enforce API-level perimeters for data exfiltration prevention — they don't provide network connectivity between Cloud Run and VPC resources.
- B
Configure a Serverless VPC Access connector and specify it in the Cloud Run service deployment
Serverless VPC Access connectors create a bridge between Cloud Run and the VPC network. The connector is specified with `--vpc-connector` at deploy time, enabling private IP access to Cloud SQL and Memorystore.
- C
Assign an external IP to the Cloud SQL and Memorystore instances — Cloud Run can reach them via public internet
Why wrong: Exposing private database resources to the public internet is a security risk and anti-pattern — the Serverless VPC Access connector provides private access.
- D
Cloud Run automatically connects to any VPC resource in the same project via project-level networking
Why wrong: Cloud Run is serverless and does not automatically have VPC access — the Serverless VPC Access connector must be explicitly configured.
Google ACE Practice Question: A team deploys a Cloud Run service that must…
This ACE practice question tests your understanding of ace exam topics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 team deploys a Cloud Run service that must access resources in a private VPC (a private Cloud SQL instance and a Redis instance on Memorystore). The Cloud Run service has no public IP connectivity requirements for these resources. What must be configured?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure a Serverless VPC Access connector and specify it in the Cloud Run service deployment
Cloud Run is a serverless compute platform that runs in a Google-managed VPC, not the customer's VPC. To access private resources like Cloud SQL and Memorystore (Redis) within a customer VPC, you must configure a Serverless VPC Access connector. This connector bridges the serverless environment to the specified VPC, enabling private, internal IP communication without public internet exposure.
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.
- ✗
Enable VPC Service Controls around Cloud Run to connect it to the VPC
Why it's wrong here
VPC Service Controls enforce API-level perimeters for data exfiltration prevention — they don't provide network connectivity between Cloud Run and VPC resources.
- ✓
Configure a Serverless VPC Access connector and specify it in the Cloud Run service deployment
Why this is correct
Serverless VPC Access connectors create a bridge between Cloud Run and the VPC network. The connector is specified with `--vpc-connector` at deploy time, enabling private IP access to Cloud SQL and Memorystore.

- ✗

Why it's wrong here
Exposing private database resources to the public internet is a security risk and anti-pattern — the Serverless VPC Access connector provides private access.
- ✗
Cloud Run automatically connects to any VPC resource in the same project via project-level networking
Why it's wrong here
Cloud Run is serverless and does not automatically have VPC access — the Serverless VPC Access connector must be explicitly configured.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that serverless services like Cloud Run can natively reach VPC resources without explicit configuration, or that VPC Service Controls provide connectivity rather than security boundaries.
Detailed technical explanation
How to think about this question
The Serverless VPC Access connector uses a set of managed Compute Engine instances in a custom subnet within your VPC, acting as a bridge via internal IPs. It supports both IPv4 and IPv6 traffic and can be configured with a specific subnet CIDR range (e.g., /28) to avoid IP exhaustion. For Cloud SQL, you must also ensure the private IP option is enabled and the VPC is peered with the Cloud SQL instance's service network, while Memorystore for Redis requires the connector to be in the same region and VPC as the Redis instance.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
