The report that can provide an instant progress overview of all fix versions across all projects is thePie Chart Report. This report allows you to create a pie chart based on any statistic type, such as Fix Version, Project, Issue Type, etc. You can use this report to compare the relative proportions of issues in different fix versions across different projects. For example, you can create a pie chart based on the Fix Version statistic type, and select all the projects that you are responsible for. This will show you how many issues are assigned to each fix version in each project, and what percentage they represent of the total issues. You can also filter the issues by status, priority, assignee, or any other criteria. This report can help you monitor the progress of your releases and identify any potential risks or delays.To generate a Pie Chart Report, follow these steps1:
Navigate to the project that you want to report on.
From the project sidebar, select Reports.
Select Pie Chart Report from the list of reports.
Select the statistic type that you want to base your pie chart on. In this case, select Fix Version.
Select the projects that you want to include in your report. You can select multiple projects by holding down the Ctrl key (Windows) or Command key (Mac) while clicking on the project names.
Optionally, select a filter to narrow down the issues that you want to include in your report. You can use an existing filter or create a new one.
Click View to generate the report.
You can also access the Pie Chart Report from your dashboard by adding the Jira Chart gadget2. This gadget allows you to display any Jira report on your dashboard.To add the Jira Chart gadget to your dashboard, follow these steps2:
Navigate to your dashboard and click Add gadget.
Search for Jira Chart and click Add gadget.
Configure the gadget settings as follows:
Select Pie Chart as the chart type.
Select the project or filter that you want to use as the data source.
Select Fix Version as the statistic type.
Optionally, select a series to further break down the data by another statistic type, such as Status or Priority.
Click Save.
You can also edit or delete the gadget at any time by clicking on the menu icon at the top right corner of the gadget.

Explanation
Sub-tasks are a type of issue that can be used to break down a parent issue into smaller and more manageable pieces. Sub-tasks can be displayed as cards in the Active sprints view of a Scrum board, which allows you to track their progress and status. However, sub-task estimations are not rolled up and displayed on the parent card, as they use a different field than the parent issue. Sub-tasks can be created by anyone who has the Create Issue permission in the project, not only by board administrators. Sub-tasks cannot be displayed as cards in the Backlog view, as they are only visible under their parent issues. Sub-tasks will not automatically get resolved when the parent is moved to the Done column, as they have their own workflow transitions and conditions.
Therefore, the correct answer is C. References: [Working with sub-tasks], [Configuring columns]

https://support.atlassian.com/jira-software-cloud/docs/understand-project-permissions-and-roles/ The two permissions that can be granted through a project role are:
A: see issues with a security level
C: share a dashboard with other auditors
These permissions are related to the project level and can be configured by the project administrator using the permission scheme or the dashboard settings.According to the documentation1, a project role can be granted the following permissions:
Browse Projects: View the project and its issues.
Create Issues: Create new issues.
Edit Issues: Edit existing issues.
Schedule Issues: Edit the Due Date of an issue, or rank issues on a Scrum board.
Move Issues: Move issues from one project to another, or change the issue type.
Assignable User: Be assigned issues.
Assign Issues: Assign issues to other users.
Resolve Issues: Resolve or reopen issues, or set a resolution when closing issues.
Close Issues: Close issues.
Modify Reporter: Modify the Reporter field of an issue.
Delete Issues: Delete issues from the project.
Link Issues: Link issues to each other, or create sub-tasks under an issue.
Set Issue Security: Set a security level on an issue to control who can see it.
View Voters and Watchers: View the list of voters and watchers for an issue.
Manage Watchers: Add or remove watchers for an issue.
View Read-Only Workflow: View the workflow diagram for an issue, but not edit it.
Manage Sprints: Start, complete, or edit sprints on a Scrum board.
Additionally, a project role can be given access to share a dashboard with other users or groups2. To do this, the project administrator needs to:
Go to Dashboards > View all dashboards
Find the dashboard to share and click > Share
Click Edit permissions
Under Add Permissions, select Group or Project Role
Choose the auditors project role from the dropdown menu
Click Add
The other options are not correct because:
B: see issues that have been archived is not a permission that can be granted through a project role.Archived issues are hidden from all users except Jira administrators3. To view archived issues, the auditors would need to have the Administer Jira global permission, which is not related to project roles.
D: subscribe other auditors to a search result is not a permission that can be granted through a project role.Subscribing other users to a search result is a feature that requires the Manage Group Filter Subscriptions global permission4. This permission is not related to project roles and can only be granted by Jira administrators to individual users or groups.
E: use bulk change to update seven issues is not a permission that can be granted through a project role.Bulk change is an operation that requires the Bulk Change global permission5. This permission is not related to project roles and can only be granted by Jira administrators to individual users or groups.

Explanation
The two actions that are reflected as scope change are dragging an estimated story from the backlog to the sprint and modifying the estimate value on a committed story. Scope change is a measure of how much work was added or removed from a sprint after it started. It is calculated by comparing the total story points committed at the start of the sprint and the total story points completed at the end of the sprint. If you add or remove issues from a sprint, or change their estimates, you are changing the scope of the sprint. The other actions mentioned in the question do not affect the scope of the sprint, as they do not change the amount of work planned or done in the sprint.

Explanation
The solution that will meet the team's requirements of using agile boards with minimal disruption to their current configuration is to use a Kanban board for tasks and a Scrum board for features in the current project.
This way, they can use different agile methodologies for different issue types without creating a new project or changing their existing configuration. They can use a Kanban board for tasks to handle them based on priority and rank and release them incrementally as needed. They can use a Scrum board for features to develop them during three week iterations with sprints and backlogs. The other solutions are either not feasible or not optimal for their needs. Therefore, the correct answer is E. References: [Creating a board], [Using a Scrum board], [Using a Kanban board]
