CAS-004 Practice Question: A DevOps team is automating the deployment of a…
A DevOps team is automating the deployment of a containerized application to production. Which THREE practices are essential for maintaining security and reliability? (Select THREE.)
⚠ Common exam trap
CompTIA CASP+ often tests the distinction between development tools (like Docker Compose) and production-grade orchestration tools (like Kubernetes with Helm), so candidates mistakenly assume Docker Compose is suitable for production deployments.
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
✓
Use Helm charts to package and deploy Kubernetes applications.
Helm charts are essential for packaging and deploying Kubernetes applications because they provide a standardized, version-controlled way to manage complex Kubernetes manifests. Helm simplifies deployment, rollback, and dependency management, which is critical for maintaining security and reliability in production environments.
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 charts to package and deploy Kubernetes applications.
Why this is correct
Helm provides reusable, versioned deployment packages with rollback capabilities.
- ✗
Use Docker Compose files for production deployments.
Why it's wrong here
Docker Compose is designed for development and single-host deployments, not production clusters.
- ✓
Use infrastructure as code tools like Terraform to provision and manage container hosts.
Why this is correct
IaC enables consistent and auditable provisioning of infrastructure.
- ✗
Manually configure each environment to handle unique settings.
Why it's wrong here
Manual configuration is error-prone and does not scale; automation is preferred.
- ✓
Implement continuous deployment pipelines with automated security testing.
Why this is correct
Automated pipelines ensure code is tested and deployed consistently, reducing human error.
