Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
This PCA practice question tests your understanding of managing and provisioning a solution infrastructure. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 organization is using Cloud Build to build container images and push them to Artifact Registry. Which step in the cloudbuild.yaml file is necessary to tag and push the image?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A step that runs 'docker push' with the Artifact Registry URL
The 'docker push' step with the destination in Artifact Registry is required to push the built image to a 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.
✓
A step that runs 'docker push' with the Artifact Registry URL
Why this is correct
This step pushes the image to Artifact Registry.
Related concept
Static NAT maps one inside address to one outside address.
✗
A step that runs 'gcloud container images push'
Why it's wrong here
'gcloud container images push' is not a valid command; use 'docker push'.
✗
A step that runs 'gsutil cp' to upload the image
Why it's wrong here
gsutil is for Cloud Storage, not for container images.
✗
A step that runs 'kubectl apply'
Why it's wrong here
kubectl is for Kubernetes, not for pushing images.
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.
Trap categories for this question
Command / output trap
'gcloud container images push' is not a valid command; use 'docker push'.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
