- A
Set up Private Service Connect for Artifact Registry
Artifact Registry uses Private Service Connect to expose a private endpoint in the VPC.
- B
Enable public access on the Artifact Registry repository
Why wrong: Public access defeats the purpose of private networking.
- C
Create a private build pool with the 'network' field set to the VPC network
Private pools require the network to be specified for VPC access.
- D
Configure a Cloud NAT gateway for the VPC
Why wrong: Cloud NAT is for outbound internet access, not for accessing private services.
- E
Grant the Cloud Build service account the 'Artifact Registry Reader' role
The service account needs permissions to pull images from Artifact Registry.

PCDE Practice Question: Building and Implementing CI/CD Pipelines for a Service
This PCDE practice question tests your understanding of building and implementing ci/cd pipelines for a service. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An engineer is configuring a Cloud Build build pool to connect to resources in a VPC network. They need to ensure the build can access a private Artifact Registry repository. Which three steps should they take?
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
✓
Set up Private Service Connect for Artifact Registry
Private pools allow builds to use a VPC network. To access private Artifact Registry, the pool must be in the same VPC as the registry endpoint (which uses Private Service Connect or VPC peering), and the service account must have permission to read from the registry.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set up Private Service Connect for Artifact Registry
Why this is correct
Artifact Registry uses Private Service Connect to expose a private endpoint in the VPC.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Enable public access on the Artifact Registry repository
Why it's wrong here
Public access defeats the purpose of private networking.
- ✓
Create a private build pool with the 'network' field set to the VPC network
Why this is correct
Private pools require the network to be specified for VPC access.

- ✓

Why this is correct
The service account needs permissions to pull images from Artifact Registry.
Related concept
Static NAT maps one inside address to one outside address.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCDE NAT questions on configuration and troubleshooting.
