With a "Shared Configuration" in JIRA, you can efficiently manage and apply consistent field configurations across numerous projects, streamlining project setup.

Custom Fields allow you to capture additional information on issues beyond the default fields provided by JIRA. By creating a custom field for "Support Team" and configuring it to appear on the appropriate screens, you can ensure that every issue is assigned to the right support team based on the type of request. This ensures efficient routing of IT support requests to the appropriate teams.

In JIRA, a scheme defines which screens and issue types a custom field is available for. This allows for customization based on project requirements, ensuring that custom fields are accessible where needed. Therefore, the correct option is "Scheme."

In JIRA, project administrators have the ability to define custom fields within their project. These custom fields can be tailored to capture specific information relevant to the project's requirements, such as priority, due date, or any other custom data.

In JIRA, you can grant a user the ability to create issues in a project without giving them full project admin access by adding them to the "Create Issues" permission scheme in the project settings. This allows users to create new issues within the project without granting them full administrative privileges.

In JIRA, you can add various gadgets to your dashboard to provide visual representations of data, such as charts, graphs, and statistics. These gadgets are customizable and offer insight into project progress or team performance.

JQL, or JIRA Query Language, is a robust querying language provided by JIRA for searching and retrieving specific sets of issues based on various criteria, facilitating efficient issue tracking.

Naming Conventions help maintain clarity and consistency in identifying and categorizing issues within JIRA. By adhering to naming conventions, team members can quickly understand the nature and purpose of each issue, which streamlines communication and improves overall project efficiency.

Bulk Change in JIRA allows users to perform actions such as editing issue attributes (like status, priority, or assignee), transitioning issues through workflow states, and moving issues between projects or boards. It's a powerful tool for making consistent changes across multiple issues at once.

Consistent issue naming practices lead to an efficient project management environment by reducing confusion, enhancing communication, and streamlining processes across the project lifecycle.
