What is the difference between a lightweight tag and an annotated tag?

A lightweight tag is just a name for a commit. An annotated tag stores extra info like the tagger's name, date, and a message.

How can a CI/CD pipeline detect a new tag to trigger deployment?

The pipeline listens for Git events and checks if the push includes a tag. If yes, it runs deployment steps automatically.

beginner

Why use tags to trigger deployments instead of branches?

Tags mark stable points like releases, so deploying from tags ensures you deploy tested versions, not ongoing work.

Which Git command creates an annotated tag?

A git tag -a v1.0 -m "Release 1.0"

B git tag v1.0

C git commit -m "Tag v1.0"

D git push origin v1.0

Option A creates an annotated tag with a message. Option B creates a lightweight tag.

What event should a CI/CD system watch to trigger deployment from tags?

A Pull request creation

B Branch merge event

C Push event including a tag

D File change in README

Deployment triggers from tags happen when a tag is pushed to the repository.

Why are tags preferred for deployment triggers over branches?

A Branches are deleted after use

B Tags mark stable release points

C Tags are faster to create

D Branches cannot trigger pipelines

Tags represent stable versions, making deployments more reliable.

Which command pushes tags to the remote repository?

A git push origin --tags

B git push origin main

C git tag push

D git commit --tags

Option A pushes all local tags to the remote repository.

What is a common use of annotated tags in deployment?

A To merge code automatically

B To speed up commits

C To delete branches

D To store release notes and author info

Annotated tags include metadata useful for release tracking.

Explain how deployment triggers from tags work in a Git-based CI/CD pipeline.

Think about what happens when you push a tag and how the pipeline reacts.

Describe the difference between lightweight and annotated tags and why annotated tags are useful for deployments.

Consider what extra info annotated tags provide.
