Part 1 – Azure Fundamentals (Q1–20)
1. What is Microsoft Azure?
Answer
Microsoft Azure is a cloud computing platform that provides more than 200 cloud services for building, deploying, and managing applications through Microsoft-managed data centers.
Azure supports:
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Serverless Computing
It helps organizations reduce infrastructure costs while improving scalability, security, and availability.
Real-Time Example
Instead of purchasing physical servers for a web application, a company deploys the application on Azure App Service, eliminating the need to manage hardware.
2. What are the different Cloud Service Models?
Answer
There are three primary cloud service models.
IaaS (Infrastructure as a Service)
Azure provides virtual machines, networking, storage, and operating systems.
Examples:
Azure Virtual Machines
Azure Virtual Network
Responsibilities:
Customer manages OS and applications.
Azure manages physical infrastructure.
PaaS (Platform as a Service)
Azure manages servers, operating systems, runtime, and middleware.
Examples:
Azure App Service
Azure SQL Database
Responsibilities:
Customer manages application code.
Azure manages the platform.
SaaS (Software as a Service)
Applications are fully managed by Microsoft.
Examples:
Microsoft 365
Dynamics 365
3. What are the deployment models in Azure?
Answer
Azure supports:
Public Cloud
Private Cloud
Hybrid Cloud
Multi-Cloud
Real-Time Example
A bank stores customer data in a private cloud while hosting its website in Azure Public Cloud.
4. What is an Azure Region?
Answer
An Azure Region is a geographical area containing one or more Azure data centers.
Examples:
East US
West Europe
Central India
South India
Organizations select regions based on:
Latency
Compliance
Disaster Recovery
Data Residency
5. What is an Availability Zone?
Answer
Availability Zones are physically separate data centers within an Azure Region.
Each zone has independent:
Power
Cooling
Networking
If one zone fails, applications continue running in another zone.
Example
Deploy three virtual machines across three Availability Zones to achieve high availability.
6. Difference between Region and Availability Zone?
| Region | Availability Zone |
|---|---|
| Geographic location | Separate datacenter within a region |
| Disaster Recovery | High Availability |
| Hundreds of miles apart | Few miles apart |
| Example: Central India | Zone 1, Zone 2, Zone 3 |
7. What is an Azure Resource Group?
Answer
A Resource Group is a logical container that holds related Azure resources.
Example:
E-commerce Project
Resource Group
Virtual Machine
SQL Database
Storage Account
App Service
Key Vault
Deleting the Resource Group removes all contained resources.
8. What is Azure Resource Manager (ARM)?
Answer
Azure Resource Manager (ARM) is the deployment and management service for Azure.
Features:
Infrastructure as Code
Templates
Role-Based Access Control
Resource Organization
Example:
Deploy an entire environment using a single ARM template.
9. What is an ARM Template?
Answer
ARM Templates are JSON files used to automate Azure resource deployment.
Benefits:
Repeatable deployments
Version control
Automation
Consistency
10. What is Azure Subscription?
Answer
An Azure Subscription is a billing and resource management boundary.
Each subscription includes:
Billing account
Resource quotas
Access control
Cost tracking
11. What is Azure Management Group?
Answer
Management Groups help organize multiple Azure subscriptions.
Example hierarchy:
Management Group
├── Production Subscription
├── Development Subscription
└── Testing Subscription
Policies can be applied to all subscriptions.
12. What is Azure Portal?
Answer
Azure Portal is a web-based graphical interface for managing Azure resources.
It allows users to:
Create resources
Monitor services
Configure networking
Manage storage
View billing
13. What is Azure CLI?
Answer
Azure CLI is a command-line tool for managing Azure resources.
Example:
az group create \
--name DemoRG \
--location centralindia
Useful for automation and scripting.
14. What is Azure PowerShell?
Answer
Azure PowerShell is a PowerShell module used to automate Azure management tasks.
Example:
New-AzResourceGroup `
-Name DemoRG `
-Location "Central India"
Preferred by Windows administrators.
15. Azure CLI vs Azure PowerShell
| Azure CLI | Azure PowerShell |
|---|---|
| Cross-platform | Windows-oriented |
| Bash syntax | PowerShell syntax |
| Best for Linux | Best for Windows |
| DevOps friendly | Admin friendly |
16. What is Azure Cloud Shell?
Answer
Azure Cloud Shell is a browser-based shell environment.
Supports:
Bash
PowerShell
Azure CLI
Git
Terraform
No installation required.
17. What are Azure Tags?
Answer
Tags are key-value pairs attached to Azure resources.
Example:
Environment=Production
Department=Finance
Owner=IT
CostCenter=1001
Benefits:
Cost management
Resource organization
Billing reports
18. What is Azure Policy?
Answer
Azure Policy enforces organizational standards.
Examples:
Allow only approved regions
Enforce resource tagging
Restrict VM sizes
Require encryption
19. What is Role-Based Access Control (RBAC)?
Answer
RBAC controls who can access Azure resources and what actions they can perform.
Common roles:
Owner
Contributor
Reader
User Access Administrator
Example
A developer is assigned the Contributor role to deploy applications but cannot change user permissions.
20. Difference between Azure Policy and RBAC?
| Azure Policy | RBAC |
|---|---|
| Controls resource compliance | Controls user permissions |
| Enforces standards | Grants access |
| Resource-focused | Identity-focused |
| Example: Only approved VM sizes | Example: Reader access |
