Microsoft Azure Questions et reponses d'entretien
Question 31. What is Azure Resource Manager (ARM) and how does it work?
Azure Resource Manager is the deployment and management service for Azure. It provides a consistent management layer that enables you to deploy and manage resources in Azure. ARM uses templates to define the resources needed for deployment.
Example:
Azure Resource Manager templates are JSON files that define the resources you need to deploy. Example: { 'resources': [{ 'type': 'Microsoft.Storage/storageAccounts', 'apiVersion': '2019-06-01', 'name': 'mystorageaccount', 'location': 'eastus', 'sku': { 'name': 'Standard_LRS' } }] }
Question 32. Explain Azure Virtual Network and its components.
Azure Virtual Network enables you to create private, isolated networks in Azure. Components include subnets, virtual machines, and network security groups. It allows secure communication between Azure resources.
Example:
You can create a virtual network with subnets for different tiers, such as frontend and backend. Example: { 'subnets': [{ 'name': 'frontend', 'addressPrefix': '10.0.1.0/24' }, { 'name': 'backend', 'addressPrefix': '10.0.2.0/24' }] }
Question 33. What is Azure Blob Storage and how is it different from Azure File Storage?
Azure Blob Storage is for unstructured data, such as documents and images. It's highly scalable. Azure File Storage, on the other hand, is for SMB-based file shares, suitable for use with applications that expect a file share.
Example:
Upload a file to Azure Blob Storage using Azure Storage Explorer or Azure CLI: az storage blob upload -f-c -n
Question 34. Explain Azure Functions and when to use them.
Azure Functions is a serverless compute service that enables you to run event-triggered code without explicitly provisioning or managing infrastructure. Use it for event-driven scenarios, like data processing, file system monitoring, etc.
Example:
Create a simple Azure Function that triggers on an HTTP request: module.exports = async function (context, req) { context.log('JavaScript HTTP trigger function processed a request.'); context.res = { body: 'Hello ' + (req.query.name || req.body.name || 'Anonymous') }; };
Question 35. What is Azure Active Directory (AAD) and its role in Azure?
Azure Active Directory is Microsoft's cloud-based identity and access management service. It provides authentication and authorization services, enabling users to securely access Azure resources and other Microsoft Online Services.
Example:
Authenticate a user using Azure AD in a web application: Use Azure AD B2C or B2B for user authentication and authorization.
