Right Answer:
Redux is a state management library for JavaScript applications, commonly used with React. The main components involved in Redux are:

1. **Store**: Holds the application's state.
2. **Actions**: Plain JavaScript objects that describe changes to the state.
3. **Reducers**: Functions that specify how the state changes in response to actions.
4. **Middleware**: Functions that extend Redux's capabilities, allowing for side effects like asynchronous actions.

Right Answer:
To implement CI/CD pipelines using Azure DevOps, follow these steps:

1. **Create a Project**: Set up a new project in Azure DevOps.
2. **Set Up Repositories**: Use Azure Repos to host your code.
3. **Create a Build Pipeline**:
- Navigate to Pipelines > Builds.
- Click on "New Pipeline" and select your repository.
- Choose a template or configure your pipeline using YAML or the classic editor.
- Define build tasks (e.g., compile code, run tests).
- Save and run the pipeline to ensure it builds successfully.

4. **Create a Release Pipeline**:
- Go to Pipelines > Releases.
- Click on "New Pipeline" and select the build artifact from your build pipeline.
- Define stages (e.g., Development, Staging, Production) and add deployment tasks (e.g., Azure App Service deployment).
- Configure triggers for automatic deployments (e.g.,

Right Answer:
IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, allowing users to manage operating systems and applications. PaaS (Platform as a Service) offers a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure. SaaS (Software as a Service) delivers software applications over the internet on a subscription basis, with users accessing the software without managing the underlying infrastructure or platform.

Right Answer:
A managed identity is an automatically managed identity in Azure that allows services to authenticate to Azure resources without storing credentials, while a service principal is a security identity created for use with applications or services to access Azure resources, requiring manual management of credentials.

Right Answer:
Azure Load Balancer operates at the transport layer (Layer 4) and distributes incoming traffic based on IP address and port, while Azure Application Gateway operates at the application layer (Layer 7) and provides features like URL-based routing, SSL termination, and Web Application Firewall (WAF) capabilities.

Right Answer:
State in mobile applications can be managed using various methods such as:

1. **Local State Management**: Using component state in frameworks like React Native or local variables in native apps.
2. **Global State Management**: Utilizing libraries like Redux, MobX, or Context API for sharing state across components.
3. **Persistent Storage**: Storing state in local storage, SQLite, or using AsyncStorage for React Native to maintain state across app sessions.
4. **Server State Management**: Fetching and synchronizing state with a backend server using APIs.
5. **Navigation State**: Managing state related to navigation using libraries like React Navigation or native navigation components.

Push notifications are messages sent from a server to a user's device to provide updates or alerts, even when the app is not actively in use. They are implemented using services like Firebase Cloud Messaging (FCM) for Android or Apple Push Notification Service (APNs) for iOS. Developers register the app with these services, obtain a device token, and then send notifications through the server to the specified device tokens.
