Regularly testing the backup restoration process ensures that JIRA administrators can confidently recover data in case of emergencies. This practice helps identify any potential issues with the backup or recovery procedures and ensures the reliability of the backup system.

In Scrum methodology, tasks are broken down into smaller units called "Tasks." This allows for better management and tracking of progress during the sprint.

The correct option is "2. Permissions." In JIRA's administration settings, permissions are used to control access to various functionalities and features within a project. By configuring permissions, administrators can grant specific rights to groups of users, such as viewing, editing, or administering issues. Navigating to the permissions section allows administrators to manage access control efficiently.

Project administrators can configure Assignee Rules to automatically assign issues to specific users or groups based on predefined criteria. This helps streamline the process by ensuring the right people are responsible for handling each issue.

In JIRA, you can control work in progress (WIP) limits on a Kanban board by setting WIP limits for each column. These limits help teams maintain a manageable workload and prevent bottlenecks in the workflow. By defining WIP limits, teams can focus on completing tasks rather than starting new ones, which improves overall efficiency and delivery speed.

The "scope change" line in a Sprint Burndown Chart represents changes in the scope of work during the sprint. This could include additional tasks being added, existing tasks being removed, or modifications to existing tasks. It helps the team understand the impact of scope changes on sprint progress.

Velocity is usually measured in story points, which represent the relative effort or size of user stories or tasks completed by a team during a sprint. It helps teams in planning and forecasting future work.

The main difference between Agile and Waterfall methodologies lies in their approach to project management. Agile emphasizes flexibility and iterative development, allowing for changes and adaptations throughout the project, whereas Waterfall follows a sequential approach with distinct phases, making changes more difficult once a phase is complete.

When designing workflows for compliance, it's crucial to document and audit all workflows for traceability. Documenting workflows helps ensure that the workflow accurately reflects the compliance requirements, and auditing ensures that the workflow is followed correctly. Transitions represent the different states an issue can move through in a workflow. Screens represent the user interface elements for capturing or displaying information. Projects represent collections of issues.

In Agile methodology, the Product Owner is responsible for prioritizing the product backlog, ensuring that the team works on the most valuable tasks first. This role involves collaborating with stakeholders to understand their needs and conveying those needs to the development team through user stories.
