Which type of data model is commonly used in NoSQL databases?
- Document-oriented
- Hierarchical

Suppose a team member submits a code change that introduces a bug. How would you use a collaboration platform to identify and address the issue?
- Comment on the code directly within the collaboration platform, initiate a discussion thread, and assign tasks to fix the bug
- Document the bug in a separate file, communicate via instant messaging, and assign blame to the team member
- Ignore the bug since it's the responsibility of the team member who introduced it, resolve it individually without involving the team
- Send a private email to the team member pointing out the issue, discuss it during the next team meeting, and wait for the next sprint planning session
Using the collaboration platform, such as commenting on the code and initiating discussions, helps identify and address the bug collaboratively. Assigning tasks and discussing the issue within the platform ensures a transparent and organized approach to bug resolution.

In Git, when does a merge conflict typically occur?
- Only in branches with the same name
- Only in complex projects with many contributors
- Randomly during the merge process
- When there are conflicting changes between the branches being merged
A merge conflict in Git typically occurs when there are conflicting changes in the branches being merged. Conflicts can arise when changes in one branch overlap with changes in another branch.
How does Gitflow handle hotfixes compared to GitHub Flow?
- Dedicated Hotfix Branch, Immediate Deployment, Merge to Master and Develop
- Feature Branch for Hotfix, Pull Requests, Automatic Merging
- Forking for Hotfix, Patch Branch, Manual Merging
- No Hotfix Branch, Continuous Deployment, Direct Merge to Master
Gitflow handles hotfixes by creating a dedicated hotfix branch, allowing for immediate deployment, and merging changes both to the master and develop branches, ensuring consistency.
In pessimistic concurrency control, transactions acquire _______ on data items to prevent other transactions from accessing them simultaneously.
- Indexes
- Locks
- Permissions
- Timestamps
In pessimistic concurrency control, transactions acquire locks on data items to prevent other transactions from accessing them simultaneously. This helps maintain data consistency by allowing only one transaction to modify a data item at a time.
