Question 1 · choose 1
A team wants to start a new, independent internal service from a starter repository's files. It doesn't want the starter's commit history, doesn't plan to send changes back, and wants its commits to count toward each developer's contribution graph. Which approach fits?
AFork the starter repository
BClone the starter and push all of it to a new repository
CCreate the repository from the starter marked as a template
DAdd the starter as a submodule of an empty repository
Show the answer and why
AFork the starter repository
Incorrect
A fork includes the entire commit history, and commits to a fork don't appear in the contributions graph.
BClone the starter and push all of it to a new repository
Incorrect
That brings the whole commit history along, which the team doesn't want.
CCreate the repository from the starter marked as a template
Correct
A repository from a template starts with a single commit and is a new project; its commits count in contribution graphs.
DAdd the starter as a submodule of an empty repository
Incorrect
That links to the starter instead of starting a new project from its files.
Creating a repository from a template is similar to forking, with important differences: a fork includes the entire commit history of the parent, while a repository created from a template starts with a single commit. Commits to a fork don't appear in your contributions graph, but commits to a repository created from a template do. A fork suits contributing to an existing project; a template suits starting a new one.
A junior developer admires a well-known open source contributor and wants to keep up with what that person works on publicly. What should he do?
AFollow the contributor to see their public activity on his dashboard
BWatch every repository the contributor has ever touched
CFork the contributor's repositories
DSponsor the contributor, which is required before anyone can see their activity
Show the answer and why
AFollow the contributor to see their public activity on his dashboard
Correct
Following people shows their public activity on your dashboard and can surface repositories they star.
BWatch every repository the contributor has ever touched
Incorrect
Watching sends notifications for those repositories, not a view of the person's activity.
CFork the contributor's repositories
Incorrect
Forks copy repositories; they don't follow a person.
DSponsor the contributor, which is required before anyone can see their activity
Incorrect
Nobody needs to sponsor someone to see their public activity; following is free.
When you follow people on GitHub, you see their public activity on your personal dashboard, and if someone you follow stars a public repository, GitHub may recommend it to you. You can unfollow someone at any time.
A CTO hears about InnerSource and asks what it would mean for the company. Which two statements are accurate? (Choose TWO.)
AThe company must publish all of its proprietary code publicly as open source projects
BOnly one team may contribute to each repository
CIt replaces pull requests with direct pushes to main
DEngineers build internal software with the practices of open source projects
ETeams can find and reuse each other's internal projects
Show the answer and why
AThe company must publish all of its proprietary code publicly as open source projects
Incorrect
InnerSource doesn't mean sharing proprietary software publicly.
BOnly one team may contribute to each repository
Incorrect
InnerSource encourages contributions from across the organization.
CIt replaces pull requests with direct pushes to main
Incorrect
Issues and pull requests are core InnerSource tools.
DEngineers build internal software with the practices of open source projects
Correct
InnerSource is a methodology that applies open source best practices to internal development.
ETeams can find and reuse each other's internal projects
Correct
InnerSource makes internal code easy to find and reuse.
InnerSource is a development methodology in which engineers build proprietary software using best practices from large open source projects. It brings transparency, encourages contributions from across the company and makes internal code easy to discover and reuse. It doesn't imply reduced security: proprietary code doesn't have to be shared publicly, and only people with the right permissions contribute.

AThe repository's Insights tab
BExplore GitHub

Show the answer and why
AThe repository's Insights tab
Incorrect

Explore offers personalized recommendations based on past contributions, stars and other activity.
CHis notifications inbox
Incorrect
The inbox lists updates from subscriptions, not recommendations.
DGitHub Marketplace
Incorrect
Marketplace offers tools to add to your work, not projects to contribute to.
