,1. Multiple Choice: What is the primary benefit of using a
distributed version control system (DVCS) over a centralized
one?
a) Enhanced security
b) No need for backups
c) Collaboration flexibility
d) Simpler branching and merging
ANS: c) Collaboration flexibility
Rationale: DVCS allows multiple developers to work
simultaneously on different features without waiting for others to
complete their tasks, enhancing collaboration.
2. Fill-in-the-Blank: In Git, the '_______' command is used to
combine the changes from one branch into another.
ANS: merge
Rationale: The 'merge' command is a fundamental Git operation
that integrates changes from different branches.
3. True/False: In version control systems, 'rebase' and 'merge' are
completely interchangeable operations with no significant
differences.
, ANS: False
Rationale: While both 'rebase' and 'merge' integrate changes
from different branches, 'rebase' rewrites history by creating new
commits for each commit in the original branch, whereas 'merge'
preserves the history.
4. Multiple Response: Which of the following are advantages of
using version control? (Select all that apply)
a) History tracking
b) Automated testing
c) Backup and recovery
d) Branching and merging
ANSs: a) History tracking, c) Backup and recovery, d)
Branching and merging
Rationale: Version control systems provide a detailed history of
changes, options for backup and recovery, and tools for branching
and merging. Automated testing is not a direct feature of version
control systems.
, d) git show
ANS: b) git diff
Rationale: 'git diff' is used to display the differences between
commits, while the other commands serve different purposes in
Git.
6. Fill-in-the-Blank: To save changes without committing them,
you can use the '_______' command in Git.
ANS: stash
Rationale: 'git stash' temporarily shelves changes you've made
to your working copy so you can work on something else, and
then come back and re-apply them later on.
7. True/False: A 'pull request' is a Git operation that updates your
local repository with changes from a remote repository.
ANS: False
Rationale: A 'pull request' is not a Git command; it's a feature
provided by hosting services like GitHub to notify project
maintainers of changes you've pushed to a repository so they can
review and merge them.
