Right Answer:
Six Sigma is a data-driven methodology aimed at improving the quality of a process by identifying and removing the causes of defects and minimizing variability. It uses statistical tools and techniques to achieve near-perfect performance, typically aiming for no more than 3.4 defects per million opportunities.

Right Answer:
Cross-functional teams in Agile are important because they bring together all the necessary skills to complete work without dependencies on other teams. This leads to faster delivery, better problem-solving, and increased innovation. To foster collaboration, encourage open communication, shared understanding of goals, mutual respect, and a focus on collective ownership.

Right Answer:
Agile ceremonies are recurring meetings within a sprint to facilitate communication, planning, and continuous improvement.

* **Sprint Planning:** The team decides what work to complete in the upcoming sprint. They discuss user stories, estimate effort, and define the sprint goal.

* **Daily Stand-up:** A brief daily meeting where the team shares progress, identifies roadblocks, and coordinates efforts. Each member typically answers: What did I do yesterday? What will I do today? Are there any impediments?

* **Sprint Review:** The team demonstrates the completed work to stakeholders, gathering feedback and ensuring alignment with expectations.

* **Sprint Retrospective:** The team reflects on the past sprint, identifying what went well, what could be improved, and defining action items to enhance future performance.

Right Answer:
I've used tools like Jira, Azure DevOps, and Trello for Agile project management. I choose them based on project needs; Jira for complex workflows and robust reporting, Azure DevOps for integrated development environments, and Trello for simpler, visually-oriented task management.

Right Answer:
A sprint backlog is a detailed plan of work for a specific sprint, derived from the product backlog. It's created during sprint planning by the development team, who select items from the product backlog they commit to complete, then break down those items into tasks and estimate the effort required for each.

Right Answer:
To facilitate effective sprint retrospectives, I would:

1. **Set the Stage:** Create a safe and open environment where the team feels comfortable sharing.
2. **Gather Data:** Collect information about what went well, what didn't, and any challenges faced during the sprint.
3. **Generate Insights:** Facilitate a discussion to identify root causes and patterns.
4. **Decide on Actions:** Collaborate to define specific, actionable, measurable, achievable, relevant, and time-bound (SMART) improvements.
5. **Close the Retrospective:** Summarize action items and assign owners.
6. **Follow Up:** Track progress on action items in subsequent sprints to ensure continuous improvement.

Right Answer:
An Inner Join returns only the rows that have matching values in both tables, while a Full Outer Join returns all rows from both tables, with matching rows where available, and NULLs where there are no matches. Therefore, the number of rows returned by a Full Outer Join can be greater than or equal to that of an Inner Join.

Right Answer:
Normalization is the process of organizing a database to reduce redundancy and improve data integrity. It involves dividing large tables into smaller, related tables and defining relationships between them. For example, instead of having a single table for customers and their orders, you might have one table for customers and another for orders, linked by a customer ID.

Denormalization is the process of combining tables to improve read performance at the cost of increased redundancy. For example, you might combine the customers and orders tables into one table that includes customer details with each order, making it faster to retrieve all information in a single query, but increasing the risk of data inconsistency.

Right Answer:
The Log Reader agent in SQL Server 2005 replication reads the transaction log of the published database to identify and capture changes (inserts, updates, deletes) that need to be replicated to the subscribers.
