The answer is kubectl apply, Helm charts, and Config Connector. These three methods are valid ways to deploy a containerized application to Google Kubernetes Engine because they each interact directly with the Kubernetes API to create or manage workloads: kubectl apply applies a manifest imperatively, Helm charts package and deploy applications declaratively, and Config Connector uses Kubernetes custom resources to provision and manage GKE resources as part of a GitOps workflow. On the Google Professional Cloud Developer exam, this question tests your understanding of deployment tools versus infrastructure commands—a common trap is confusing cluster creation with application deployment. Remember that gcloud container clusters create provisions the cluster itself, not an app, and Cloud Storage is a bucket service, not a deployment mechanism. A helpful memory tip is “kubectl, Helm, Config—three ways to deploy; gcloud and Storage stay away.”
PCD Deploying applications Practice Question
This PCD practice question tests your understanding of deploying applications. 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.
Which THREE methods are valid ways to deploy a containerized application to Google Kubernetes Engine (GKE)?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Helm to install a chart.
Options A, B, and C are correct. A: kubectl apply is direct. B: Helm charts are commonly used. C: Config Connector manages GKE resources via Kubernetes custom resources. Option D is wrong because gcloud container clusters create creates clusters, not deploys apps. Option E is wrong because Cloud Storage does not deploy directly to GKE.
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.
✓
Use Helm to install a chart.
Why this is correct
Helm is a package manager for Kubernetes.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use gcloud container clusters create to deploy the application.
Why it's wrong here
That command creates a cluster, not an application.
✗
Upload the container image to Cloud Storage and use a trigger to deploy.
Why it's wrong here
Cloud Storage does not trigger GKE deployments natively.
✓
Use kubectl apply with a Deployment manifest.
Why this is correct
Direct imperative or declarative deployment.
Related concept
Read the scenario before looking for a memorised answer.
✓
Use Config Connector to create a KubernetesDeployment resource.
Why this is correct
Config Connector manages GCP resources via Kubernetes CRDs.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
