200-901 Practice Question: A team is implementing a CI/CD pipeline using…
A team is implementing a CI/CD pipeline using Jenkins. The pipeline must build a Docker image and push it to a private registry. Which Jenkins plugin is specifically designed to handle Docker builds and pushes?
⚠ Common exam trap
Many exam-takers confuse the general-purpose Pipeline Plugin with the Docker-specific Docker Pipeline Plugin, assuming that Pipeline alone can handle Docker builds, when in fact it requires the dedicated plugin for native Docker steps.
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
✓
Docker Pipeline Plugin
The Docker Pipeline Plugin is the correct choice because it provides Jenkins Pipeline steps specifically for building and pushing Docker images, such as `docker.build()` and `docker.withRegistry()`. This plugin integrates Docker operations directly into Declarative or Scripted Pipelines, enabling seamless CI/CD workflows without requiring shell commands.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Credentials Plugin
Why it's wrong here
The Credentials Plugin stores and binds secrets such as registry usernames and tokens, but it performs no image build or push operations. It is the right choice when a pipeline needs to reference stored credentials securely, not when Docker build and push steps must be executed.
- ✗
Pipeline Plugin
Why it's wrong here
The Pipeline Plugin provides the scripted and declarative pipeline DSL for orchestrating stages, but it contains no Docker build or registry push capability itself. It is correct when defining pipeline structure, whereas Docker build and push require the Docker Pipeline plugin's docker.build and docker.withRegistry steps.
- ✓
Docker Pipeline Plugin
Why this is correct
The Docker Pipeline Plugin exposes a docker global variable in Jenkinsfiles, letting pipeline stages build images and push them to a private registry using credentials-bound registry authentication. This directly satisfies the stem's requirement for a Jenkins plugin specifically designed to handle Docker builds and pushes.
- ✗
Git Plugin
Why it's wrong here
The Git Plugin clones repositories and triggers builds on commits; it cannot build or push Docker images. It is the right choice when Jenkins must poll or webhook-checkout source code, but the stem requires Docker image construction and registry publication, which the Docker Pipeline plugin supplies.
