In Agile development, breaking down large user stories into smaller ones is essential for better estimation, implementation, and tracking. When a user story is too complex to estimate accurately, it should be broken down into smaller, more manageable pieces. This allows the team to understand and deliver value incrementally, reducing risks associated with uncertainties and facilitating collaboration among team members.

The correct option is Effort Remaining. In a Burndown Chart, the y-axis typically represents the amount of effort remaining to complete the work. This could be measured in various units such as story points, hours, or tasks. It provides a visual indication of the progress made towards completing the sprint backlog.

In JIRA, a sub-task is used to break down a larger issue into smaller, more manageable tasks. Sub-tasks are essentially smaller units of work that contribute to the completion of the parent issue.

In JIRA, Bulk Operations allow users to perform actions like editing multiple issues' fields at once, transitioning multiple issues through workflow states, moving multiple issues to another project, cloning issues, deleting multiple issues, and more.

In JIRA, permission schemes are used to control access to various actions and features within the system. These schemes define who can perform which actions on different aspects of JIRA projects and issues.

In JIRA, using descriptive titles that clearly indicate the issue's content is a recommended approach. This helps users quickly understand the nature of the issue without having to delve into the details. Clear and concise titles facilitate efficient communication and collaboration within the team.

The Sprint Review meeting in Agile Scrum serves the purpose of showcasing the completed work to stakeholders for feedback and validation. It allows stakeholders to provide input, which can influence future product increments. This transparency promotes collaboration and ensures alignment with stakeholders' expectations.

Option 1: "Sub-tasks" is the correct option. When you have a parent issue representing a feature in JIRA and need to track the development tasks required to complete that feature, you create sub-tasks. Sub-tasks break down the parent issue into smaller, manageable tasks, each representing a specific aspect of the feature development. These sub-tasks are then linked to the parent issue, allowing for hierarchical organization and clear visibility into the progress of individual tasks contributing to the completion of the feature.

When restoring a JIRA instance from a backup, there are several methods available. XML import involves exporting data from one instance and importing it into another. Database import restores a JIRA instance by importing data directly into the database. Automated system restore relies on backup tools within JIRA to automate the restoration process. Manual file copy involves manually copying files and directories from a backup location to the appropriate directories in the JIRA instance.

During Sprint Execution, the Scrum Team holds a Daily Stand-up meeting to discuss progress and identify any impediments. This meeting helps the team members to stay synchronized, identify any obstacles that may hinder progress, and collaborate on finding solutions to overcome them.

SLAs in JIRA Service Desk help in ensuring better customer satisfaction by setting expectations regarding response and resolution times. By defining clear SLAs, customers know what to expect, leading to improved satisfaction levels.

Consistency in naming conventions simplifies searching within JIRA projects. When issue names follow a standardized format, users can easily locate specific tasks, documents, or discussions related to their work. This fosters efficiency and collaboration among team members, ultimately improving project outcomes.
