Interview questions and answers

Here are some interview questions we suggest you use to assess the knowledge of an Azure developer.

1. How do you secure data in Azure Blob storage?

Expected answer: Use of Azure Active Directory for access control, encryption of data at rest and in transit, and proper configuration of public access level.

2. What is Azure Service Bus, and when would you use it?

Expected answer: Azure Service Bus is a messaging service used for decoupling applications and services in Azure. It's used for scenarios that require reliable, secure communication, especially where asynchronous messaging or communication between disconnected systems is needed.

3. Describe how you would implement a failover strategy in Azure.

Expected answer: Utilizing Azure Site Recovery for disaster recovery, understanding geo-redundancy, and knowledge of load balancers for high availability.

4. How do you manage state in Azure Functions?

Expected answer: Azure Functions are stateless by default. You can use Azure Durable Functions to manage state, which allows writing stateful functions in a serverless environment. This is useful for orchestrating complex workflows.

5. Explain the difference between Azure Service Fabric and Kubernetes.

Expected answer: Service Fabric is a platform for microservices and container orchestration native to Azure, while Kubernetes is an open-source container orchestration tool.

6. How does Azure Active Directory differ from traditional Active Directory?

Expected answer: Azure Active Directory (Azure AD) is a cloud-based identity and access management service, while traditional Active Directory (AD) is a directory service for Windows domain networks. Azure AD provides a range of identity services, such as multi-factor authentication, device registration, and self-service password management that are unavailable in traditional AD.

7. Describe how you would use Azure DevOps for CI/CD.

Expected answer: Azure DevOps provides a suite of tools for implementing CI/CD pipelines. It can automate the steps for building, testing, and deploying applications. Key components include Azure Repos for source control, Azure Pipelines for CI/CD, and Azure Artifacts for package management.
