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
✓
Relying on the default values defined in the chart's values.yaml file
Helm values can be supplied via the --set flag for inline values, the --values (-f) flag for YAML files, and by setting environment variables or default values within the chart's values.yaml file.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Relying on the default values defined in the chart's values.yaml file
Why this is correct
Charts inherently utilize the default values defined in their packaged values.yaml file.
- ✗
Directly modifying the deployed Kubernetes Pod annotations via oc patch
Why it's wrong here
Modifying deployed pod annotations post-installation is not a Helm chart parameter injection mechanism.
- ✓
Passing individual key-value pairs using the --set flag on the CLI
Why this is correct
--set allows overriding individual chart values inline.
- ✓
Supplying a custom YAML configuration file using the --values flag
Why this is correct
--values (-f) provides a structured YAML file of parameter overrides.
- ✗
Injecting values through the cluster-wide OAuth configuration map
Why it's wrong here
OAuth config maps manage authentication settings and are not used to parameterize Helm charts.
