CV0-004 Deployment Practice Question
An organization is implementing a CI/CD pipeline for a critical application. The team wants to deploy a new version to a small subset of users initially to validate performance and functionality before rolling out to the entire user base. Which deployment strategy best fits this requirement?
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
✓
Canary deployment
Canary deployment releases the new version to a small percentage of users, monitors its performance, and gradually increases traffic if successful.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rolling deployment
Why it's wrong here
Rolling deployment replaces instances in batches across the whole fleet, so every user eventually reaches the new version with no isolated subset held back for validation. It is tempting because it limits simultaneous risk during release, but it suits capacity-preserving updates, not canary-style validation on a small user cohort before full rollout.
- ✗
Blue/green deployment
Why it's wrong here
Blue/green deployment switches all traffic from the old environment to the new one at once, so the entire user base reaches the new version simultaneously rather than a small subset. It is tempting because it enables rapid rollback, but it suits full cutover releases, not incremental validation on a limited user group.
- ✗
Immutable deployment
Why it's wrong here
Immutable deployment replaces servers with freshly built images rather than routing a portion of live users to the new version. It is tempting because immutability simplifies rollback and configuration drift, but it addresses infrastructure consistency, not the requirement to expose only a small subset of users before full rollout.
- ✓
Canary deployment
Why this is correct
Canary deployment routes a small percentage of live traffic to the new version while the majority continues using the stable release, directly satisfying the requirement to validate performance and functionality with a subset of users before full rollout. Unlike blue-green, which switches all traffic at once, canary limits blast radius incrementally.
