Right Answer:
We ensure consistent Agile processes through:

* **Training and coaching:** Ensuring the team understands Agile principles and practices.
* **Regular audits and retrospectives:** Identifying deviations and areas for improvement.
* **Using tools and templates:** Standardizing processes and providing guidelines.
* **Defining clear roles and responsibilities:** Ensuring everyone knows their part in the process.
* **Promoting open communication and feedback:** Encouraging early detection of issues.

Right Answer:
Success in Agile is measured by:

* **Output:** Delivering valuable, working software frequently; achieving the product vision; meeting business goals; customer satisfaction; and predictability (consistent delivery).
* **Team Health:** Team morale; continuous improvement (velocity trends, retrospectives leading to action); collaboration; self-organization; and sustainable pace.

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:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."

Right Answer:
I would assess the organization's context, choose a suitable scaling framework like SAFe or LeSS based on needs, implement it incrementally with training and coaching, focusing on value delivery, and continuously inspect and adapt the implementation based on feedback and results.

Right Answer:
An API endpoint is a specific URL or URI where an API can be accessed by a client to perform operations like retrieving or sending data. It defines the location and method (such as GET, POST) for interacting with the API.

Right Answer:
HTTP methods are standardized request types used in APIs to perform actions on resources. The main methods are:

1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.

These methods define the action to be performed on the specified resource in the API.

Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.

Right Answer:
RESTful principles include:

1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.

These principles guide the design of APIs to be scalable, efficient, and easy to use.

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

Right Answer:
**Volatile Queue:** A volatile queue is a temporary message storage that holds messages in memory and is lost if the system crashes or restarts. It is used for short-lived messages that do not require persistence.

**Dead Letter Queue (DLQ):** A dead letter queue is a special queue that stores messages that cannot be delivered to their intended destination due to errors, such as message format issues or exceeding delivery attempts. It allows for later analysis and handling of these problematic messages.

Right Answer:
Boxing is the process of converting a value type (like int or char) into an object type, while unboxing is the process of converting an object type back into a value type.

Right Answer:
To make an application offline in ASP.NET 2.0, you can use the `Application_BeginRequest` event in the `Global.asax` file to check for a specific condition (like a flag in the configuration) and then redirect users to an offline page. Additionally, you can set up a custom error page for HTTP status codes like 503 to inform users that the application is temporarily unavailable.

Right Answer:
ASP.NET is a web application framework developed by Microsoft for building dynamic web sites, applications, and services.

Right Answer:
ASP.NET supports several modes for storing session state:

1. **InProc**: Stores session data in the memory of the ASP.NET worker process. Fast but not suitable for web farms.

2. **StateServer**: Stores session data in a separate process (ASP.NET State Service). Allows sessions to be maintained across multiple web servers.

3. **SQLServer**: Stores session data in a SQL Server database. Suitable for web farms and provides persistence.

4. **Custom**: Allows developers to implement their own session state storage mechanism.

5. **Cookie**: Stores session data in a cookie on the client-side. Limited in size and security concerns.

6. **OutOfProc**: A general term that includes both StateServer and SQLServer modes, where session data is stored outside the application process.
