- A
helm deploy webapp ./chart -n production --set image.tag=v2.1
Why wrong: `helm deploy` is not a valid Helm command. Use `helm install` for initial deployment or `helm upgrade` for updates.
- B
helm install webapp ./chart -n production --set image.tag=v2.1
`helm install [RELEASE] [CHART]` installs a chart with the given release name. `-n production` targets the namespace. `--set image.tag=v2.1` overrides the chart's default value.
- C
kubectl apply -f helm-chart.yaml -n production --image-tag=v2.1
Why wrong: `kubectl apply` doesn't understand Helm charts — Helm must render and apply the templates.
- D
helm apply webapp -n production --chart=./chart --tag=v2.1
Why wrong: `helm apply` is not a valid Helm command. `--chart` and `--tag` are not valid flags. Use `helm install` with `--set`.
Quick Answer
The answer is `helm install webapp ./chart -n production --set image.tag=v2.1`. This command is correct because `helm install` deploys a chart into a Kubernetes cluster, and the `--set` flag overrides default values in the chart’s `values.yaml` file—here, changing `image.tag` to `v2.1`. The `-n` flag specifies the target namespace, while the release name `webapp` is provided as the first positional argument, matching Helm’s required syntax. On the Google Associate Cloud Engineer exam, this tests your ability to use Helm for application lifecycle management in GKE, a common scenario for deploying microservices with custom configurations. A frequent trap is confusing `helm install` with `helm upgrade` or forgetting that `--set` only overrides specific keys without modifying the chart itself. Memory tip: think of the order as “release name, chart path, namespace, then set” — or simply remember the mnemonic “Name, Chart, Namespace, Set” to keep the sequence straight.
Google ACE Deploying and implementing a cloud solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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.
A team packages their Kubernetes application as a Helm chart. They need to install it into a GKE cluster with the release name 'webapp' in the 'production' namespace, overriding the default image tag to 'v2.1'. Which Helm command achieves this?
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
helm install webapp ./chart -n production --set image.tag=v2.1
Option B is correct because `helm install` is the standard Helm command to deploy a chart into a cluster, and the `--set` flag overrides default values like `image.tag`. The `-n` flag specifies the namespace, and the release name 'webapp' is given as the first argument. This matches the Helm CLI syntax exactly.
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.
- ✗
helm deploy webapp ./chart -n production --set image.tag=v2.1
Why it's wrong here
`helm deploy` is not a valid Helm command. Use `helm install` for initial deployment or `helm upgrade` for updates.
- ✓
helm install webapp ./chart -n production --set image.tag=v2.1
Why this is correct
`helm install [RELEASE] [CHART]` installs a chart with the given release name. `-n production` targets the namespace. `--set image.tag=v2.1` overrides the chart's default value.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
kubectl apply -f helm-chart.yaml -n production --image-tag=v2.1
Why it's wrong here
`kubectl apply` doesn't understand Helm charts — Helm must render and apply the templates.
- ✗
helm apply webapp -n production --chart=./chart --tag=v2.1
Why it's wrong here
`helm apply` is not a valid Helm command. `--chart` and `--tag` are not valid flags. Use `helm install` with `--set`.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Helm commands with kubectl or assume a generic 'deploy' verb exists, when Helm strictly uses `install` for first-time deployments and `upgrade` for updates.
Trap categories for this question
Command / output trap
`helm deploy` is not a valid Helm command. Use `helm install` for initial deployment or `helm upgrade` for updates.
Detailed technical explanation
How to think about this question
Helm charts use a `values.yaml` file for default configuration, and the `--set` flag overrides specific values at install time using a key=value syntax. Under the hood, Helm merges these overrides with the chart’s defaults and generates Kubernetes manifests via Go templating. In a real-world scenario, using `--set` allows CI/CD pipelines to inject version tags without modifying the chart source, enabling immutable releases.
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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
