💡 Hint

Common Mistakes

Using 'push' instead of 'clone' will try to send changes, not download.

The git clone command copies a remote repository to your local machine.

Complete the command to create a new branch named 'feature'.

Git

git [1] feature

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'checkout' creates and switches branches, not just create.

The git branch command creates a new branch without switching to it.

Fix the error in the command to switch to the 'develop' branch.

Git

git [1] develop

Drag options to blanks, or click blank then click option'

Bclone

Cpush

Dcheckout

Attempts:

💡 Hint

Common Mistakes

Using 'commit' tries to save changes, not switch branches.

The git checkout command switches branches in your local repository.

4fill in blank

hard

Fill both blanks to create a new branch and switch to it in one command.

Git

git [1] -b [2]

Drag options to blanks, or click blank then click option'

Acheckout

Bfeature

Cdevelop

Dcommit

Attempts:

💡 Hint

Common Mistakes

Using 'commit' instead of 'checkout' will not create or switch branches.

The command git checkout -b feature creates and switches to the 'feature' branch.

5fill in blank

hard

Fill all three blanks to merge the 'feature' branch into 'main' and push changes.

Git

git [1] feature && git [2] origin [3]

Drag options to blanks, or click blank then click option'

Cmain

Dpull

💡 Hint

Common Mistakes

Using 'pull' instead of 'push' will fetch changes, not send them.

This sequence merges 'feature' into 'main' locally, then pushes 'main' to the remote repository.

Practice

1. Why is having a workflow agreement important when using git in a team?

easy

A. It helps prevent conflicts and keeps the code organized.

B. It makes the code run faster on all machines.

C. It automatically fixes bugs in the code.

D. It allows unlimited access to the repository without rules.

Solution

1. Step 1: Understand the purpose of workflow agreement

   A workflow agreement sets clear rules for how team members use Git, helping avoid confusion.

2. Step 2: Identify the main benefit

   By following agreed rules, conflicts are reduced and code stays organized, improving teamwork.

3. Final Answer:

   It helps prevent conflicts and keeps the code organized. -> Option A

4. Quick Check:

   Workflow agreement = prevent conflicts and organize code [OK]

Hint: Workflow agreement = clear rules to avoid conflicts [OK]

Common Mistakes:

• Thinking workflow speeds up code execution
• Believing workflow fixes bugs automatically
• Assuming workflow removes access controls

2. Which of the following is the correct way to start a new branch following a team workflow?

easy

A. git branch -m feature/login

B. git checkout -b feature/login

C. git push origin feature/login

D. git merge feature/login

Solution

1. Step 1: Identify the command to create and switch to a new branch

   git checkout -b branch-name creates and switches to the new branch in one step.

2. Step 2: Check other options

   git branch -m renames a branch, git push uploads changes, and git merge combines branches.

3. Final Answer:

   git checkout -b feature/login -> Option B

4. Quick Check:

   Create and switch branch = git checkout -b [OK]

Hint: Create and switch branch with git checkout -b [OK]

Common Mistakes:

• Using git branch -m to create a branch
• Trying to push before creating the branch
• Merging before creating or switching branches

3. Given this team workflow: always pull before pushing. What will happen if you run these commands in order?

git push origin main
git pull origin main

medium

A. Pull will overwrite remote changes without warning.

B. Push will succeed even if remote has new commits.

C. Push and pull commands do nothing without commit.

D. Push will fail if remote has new commits; pull updates local branch.

Solution

1. Step 1: Understand push behavior when remote has new commits

   If remote has new commits, git push will be rejected to avoid overwriting others' work.

2. Step 2: Understand pull updates local branch

   git pull fetches and merges remote changes into local branch, updating it.

3. Final Answer:

   Push will fail if remote has new commits; pull updates local branch. -> Option D

4. Quick Check:

   Push fails if remote ahead; pull updates local [OK]

Hint: Always pull before push to avoid conflicts [OK]

Common Mistakes:

• Assuming push always succeeds
• Thinking pull overwrites remote
• Believing push/pull do nothing without commits

4. A team member forgot to pull before pushing and got this error:

! [rejected] main -> main (fetch first)

What should they do to fix this?

medium

A. Delete the local branch and create a new one.

B. Run git push --force to overwrite remote changes.

C. Run git pull origin main then resolve any conflicts before pushing again.

D. Ignore the error and try pushing again immediately.

Solution

1. Step 1: Understand the error meaning

   The error means remote has new commits; local branch is behind.

2. Step 2: Correct fix is to pull and merge changes

   Running git pull origin main updates local branch; conflicts can be resolved before pushing.

3. Final Answer:

   Run git pull origin main then resolve any conflicts before pushing again. -> Option C

4. Quick Check:

   Pull first to sync before push [OK]

Hint: Pull and fix conflicts before pushing [OK]

Common Mistakes:

• Using git push --force without caution
• Deleting branches unnecessarily
• Ignoring errors and retrying push

5. Your team agreed on a workflow where all feature branches must be reviewed before merging into main. Which Git command sequence best supports this workflow?

hard

A. Create feature branch, push to remote, open pull request, merge after approval.

B. Commit directly to main branch without branches or reviews.

C. Merge feature branch locally and push to main without review.

D. Delete main branch and work only on feature branches.

Solution

1. Step 1: Identify workflow steps for review

   Creating a feature branch and pushing it allows others to review changes before merging.

2. Step 2: Use pull requests for review and controlled merging

   Opening a pull request enables team review; merging happens only after approval.

3. Final Answer:

   Create feature branch, push to remote, open pull request, merge after approval. -> Option A

4. Quick Check:

   Feature branch + PR + review = safe merge [OK]

Hint: Use pull requests for review before merging [OK]

Common Mistakes:

• Committing directly to main branch
• Merging without review
• Deleting main branch accidentally
