Microsoft Fabric Interview Questions [Top 20]

Q1: What is Microsoft Fabric (Azure Service Fabric), and how does it differ from other Azure services? 
Answer: Microsoft Fabric is a distributed systems platform for building scalable, reliable, and easily managed applications. It differs from other Azure services by providing a higher-level programming model for building microservices-based applications.

Q2: Explain the concept of microservices and how Microsoft Fabric supports it.
Answer: Microservices is an architectural style that structures an application as a collection of loosely coupled services. Microsoft Fabric supports microservices by providing a runtime environment for deploying, managing, and scaling individual services independently.
 
Q3: How does Microsoft Fabric handle stateful and stateless services?
Answer: Microsoft Fabric provides support for both stateful and stateless services. Stateful services store their state within the service instance, allowing for persistence and reliability. Stateless services do not maintain any state, making them highly scalable.
 
Q4: What are the key benefits of using Microsoft Fabric for application development?
Answer: Key benefits of using Microsoft Fabric include scalability, reliability, high availability, fault tolerance, and the ability to easily upgrade and manage applications.
 
Q5: Describe the architecture of Microsoft Fabric and its components.
Answer: Microsoft Fabric architecture consists of clusters, nodes, services, partitions, and replicas. Clusters contain multiple nodes, which host services. Services are divided into partitions, and each partition has multiple replicas for reliability and availability.
 
Q6: How does Microsoft Fabric handle service communication and discovery?
Answer: Microsoft Fabric uses a reliable messaging system for service communication. It also provides a built-in service discovery mechanism that allows services to locate and communicate with each other.
 
Q7: What is the role of Actors in Microsoft Fabric, and how do they work?
Answer: Actors in Microsoft Fabric provide a programming model for building highly concurrent and scalable applications. Actors are lightweight objects that encapsulate state and behavior, and they communicate through message passing.
 
Q8: Explain the reliability and scalability features of Microsoft Fabric.
Answer: Microsoft Fabric provides automatic failover and recovery mechanisms for ensuring application reliability. It also supports automatic scaling of services based on resource usage and demand.
 
Q9: How does Microsoft Fabric handle upgrades and versioning of services?
Answer: Microsoft Fabric supports rolling upgrades, allowing services to be updated without downtime. It also provides versioning support to ensure compatibility between different versions of services.
 
Q10: What are the deployment options available for Microsoft Fabric applications?
Answer: Microsoft Fabric applications can be deployed on-premises, on Azure, or in other cloud environments. It also supports containerized deployments using Docker.
 
Q11: How does Microsoft Fabric ensure high availability and fault tolerance?
Answer: Microsoft Fabric ensures high availability and fault tolerance by replicating service instances across multiple nodes and automatically recovering from node failures.
 
Q12: Explain how to monitor and diagnose issues in a Microsoft Fabric application.
Answer: Microsoft Fabric provides monitoring and diagnostic tools such as the Service Fabric Explorer and Azure Monitor. These tools allow you to monitor application health, track performance metrics, and diagnose issues.
 
Q13: What are the security best practices for Microsoft Fabric applications?
Answer: Security best practices for Microsoft Fabric applications include securing communication using SSL/TLS, implementing role-based access control (RBAC), and securing sensitive data using encryption.
 
Q14: Describe the role of the Service Fabric Explorer in managing and monitoring applications.
Answer: The Service Fabric Explorer is a web-based tool that provides a graphical interface for managing and monitoring Microsoft Fabric applications. It allows you to view cluster status, manage services, and monitor health and performance.
 
Q15: How does Microsoft Fabric handle service partitioning and load balancing?
Answer: Microsoft Fabric uses partitioning to divide services into smaller units for scalability. It also performs load balancing by distributing partitions across nodes based on resource utilization.
 
Q16: Can you explain how to implement rolling upgrades in Microsoft Fabric?
Answer: Rolling upgrades in Microsoft Fabric can be implemented by updating service instances one by one, ensuring that the application remains available during the upgrade process.
 
Q17: Describe the usage of application manifests and service manifests in Microsoft Fabric applications.
Answer: Application manifests define the structure and dependencies of an application, while service manifests specify the properties and configuration of individual services within the application.
 
Q18: What are the programming languages supported by Microsoft Fabric?
Answer: Microsoft Fabric supports multiple programming languages, including C#, Java, and Node.js.
 
Q19: How do you handle long-running and durable workflows in Microsoft Fabric?
Answer: Long-running and durable workflows can be implemented using the Microsoft Fabric Reliable Actors or the Durable Functions programming models.
 
Q20: Can you discuss any experiences or challenges you faced while working with Microsoft Fabric?
Answer: This question aims to assess the candidate's practical experience and problem-solving skills related to Microsoft Fabric. Candidates can share their experiences with deployment, scalability, reliability, troubleshooting, or other relevant challenges they encountered and how they resolved them.
