Recall & Review

beginner

What is a rollback strategy in Jenkins?

A rollback strategy in Jenkins is a plan or method to revert an application or system to a previous stable state after a failed deployment or error.

beginner

Name two common rollback strategies used in Jenkins pipelines.

Two common rollback strategies are:<br>1. Re-deploying the last successful build.<br>2. Using blue-green deployment to switch traffic back to the stable environment.

How can Jenkins pipeline help automate rollback?

Jenkins pipelines can automate rollback by scripting steps to detect failures and trigger deployment of a previous stable build automatically.

intermediate

What is the benefit of using blue-green deployment as a rollback strategy?

Blue-green deployment allows quick rollback by switching user traffic between two identical environments, minimizing downtime and risk.

beginner

What Jenkins feature helps keep track of previous builds for rollback?

Jenkins keeps a history of builds with unique build numbers, allowing easy identification and redeployment of previous stable builds for rollback.

What does a rollback strategy aim to do in Jenkins?

A Increase build speed

B Deploy new features faster

C Revert to a previous stable state after failure

D Monitor server health

Rollback strategies focus on reverting to a stable state after deployment issues.

Which Jenkins feature helps automate rollback?

A Pipeline scripting

B Static code analysis

C User authentication

D Build triggers

Pipeline scripting allows automation of rollback steps on failure.

What is a key advantage of blue-green deployment for rollback?

A Reduces build time

B Requires no extra servers

C Eliminates need for testing

D Switch traffic instantly between environments

Blue-green deployment enables instant traffic switch to a stable environment.

How does Jenkins identify previous builds for rollback?

A By user names

B By unique build numbers

C By server IP

D By deployment time only

Jenkins assigns unique build numbers to track builds.

Which rollback strategy involves redeploying the last successful build?

A Re-deployment rollback

B Blue-green deployment

C Canary release

D Feature toggling

Re-deployment rollback uses the last stable build to revert changes.

Explain how Jenkins pipelines can be used to implement rollback strategies.

Think about how scripts can automate steps after a failed deployment.

Describe the blue-green deployment rollback strategy and its benefits.

Imagine having two identical setups and switching users between them.
