- A
Set up Cloud NAT for the Cloud Build workers
Why wrong: Cloud NAT provides outbound connectivity but workers still have public IPs.
- B
Configure Artifact Registry with VPC Service Controls
Why wrong: VPC Service Controls secure the registry but do not affect the build workers' network.
- C
Use a private pool in Cloud Build
Private pools run workers in your VPC with no public IPs, enabling private builds.
- D
Connect the Cloud Build service account to a shared VPC
Why wrong: This allows Cloud Build to access VPC resources but does not remove public IPs from workers.

Cloud Digital Leader Google Cloud Products and Services Practice Question
This GCDL practice question tests your understanding of google cloud products and services. 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 is using Cloud Build to build container images and push them to Artifact Registry. The build process involves sensitive dependencies that should not be exposed to the internet. The team wants to ensure that all builds execute on a private network without public IP addresses. What should the team configure?
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
✓
Use a private pool in Cloud Build
Cloud Build supports private pools that provide workers in a customer-managed VPC network, allowing builds to run without public IP addresses and access internal resources. Connecting the project to a shared VPC only enables network access but workers still have public IPs unless private pools are used. Using Artifact Registry VPC-SC perimeters helps secure the registry but not the build workers. Cloud NAT provides outbound internet but does not remove public IPs from workers.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set up Cloud NAT for the Cloud Build workers
- ✗
Configure Artifact Registry with VPC Service Controls
Why it's wrong here
VPC Service Controls secure the registry but do not affect the build workers' network.

- ✗
Connect the Cloud Build service account to a shared VPC
Why it's wrong here
This allows Cloud Build to access VPC resources but does not remove public IPs from workers.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
