Azure Networking Interview Q&A

 

---

1. What is the difference between NSG and ASG?

Network Security Group (NSG):

• Controls inbound and outbound traffic to Azure resources.

• Applied at subnet or network interface (NIC) level.

• Rules are based on IP address, port, and protocol.

Application Security Group (ASG):

• Logical group of VMs based on application role.

• Used in conjunction with NSGs to simplify rule management.

• Enables defining security rules based on application tags rather than individual IPs.

Use Case: In a multi-tier application, ASGs can group front-end, back-end, and database VMs, allowing you to apply security rules cleanly and efficiently.

---

2. How can you block access to a VM from a subnet?

• By default, Azure allows traffic between subnets within a VNet due to the built-in NSG rule: AllowVnetInBound (priority 65000).

• To block access:

  • Create a Deny rule in the NSG with a priority number lower than 65000.

  • Example: Create a rule with priority 100 to deny traffic from a specific subnet.

---

3. Are Azure NSGs stateful or stateless?

NSGs are stateful.

• This means that if an inbound rule allows traffic into a VM, the response is automatically allowed outbound.

• Example: If port 80 is allowed inbound, you do not need to explicitly allow outbound port 80 for response traffic.

Virtualization: An In-Depth Explanation

 

Background

Traditionally, a physical server runs a single operating system with applications installed directly on it. This model has limitations such as underutilized hardware, complex management when handling many servers, and difficulty scaling.

Virtualization solves these problems by adding a layer of abstraction between physical hardware and the operating system. It allows multiple virtual instances, each running its own OS and applications, to coexist on a single physical server. This technology is foundational in modern data centers and cloud computing.

---

Components of Virtualization

1. Hypervisor (Virtual Machine Monitor):

• The hypervisor is the software layer that manages the physical hardware and allocates resources to multiple virtual machines (VMs).

• There are two types of hypervisors:

  • Type 1 (Bare-metal): Runs directly on the physical hardware (e.g., Microsoft Hyper-V, VMware ESXi).

  • Type 2 (Hosted): Runs on top of an existing operating system (e.g., VMware Workstation, Oracle VirtualBox).

2. Virtual Machines (VMs):

• VMs are the isolated virtual instances created by the hypervisor. Each VM acts like an independent computer with its own virtual CPU, memory, storage, and networking.

• Multiple VMs can run simultaneously on a single physical server, maximizing resource use.

---

Key Concepts in Virtualization

• Server Virtualization:
  A physical server is divided into multiple VMs, each running its own OS, improving hardware utilization and simplifying server management.

• Resource Pooling:
  Physical resources such as CPU, memory, and storage are pooled and dynamically assigned to VMs based on demand.

• Isolation:
  VMs run independently, ensuring that faults or security issues in one VM do not impact others.

• Snapshotting and Cloning:
  Snapshots capture the state of a VM at a specific time for easy backup and recovery. Cloning allows rapid duplication of VMs for scaling or testing.

---

Benefits of Virtualization

• Server Consolidation:
  Run multiple VMs on a single physical machine, reducing hardware costs and improving energy efficiency.

• Flexibility and Scalability:
  Easily create, modify, or scale VMs to meet changing workload demands.

• Disaster Recovery:
  Quickly restore VMs from snapshots or backups to minimize downtime during failures.

• Resource Optimization:
  Allocate or free resources dynamically based on workload, ensuring efficient hardware use.

• Testing and Development:
  Provide isolated environments to develop and test applications without affecting production systems.

🔷 Azure Resources

 

Azure resources are the fundamental building blocks of your cloud infrastructure in Microsoft Azure. These include services such as virtual machines, databases, storage accounts, and many others. Each resource is an individual manageable entity that you can provision, configure, and monitor.

---

Resource Groups in Azure

Definition:
A Resource Group is a logical container that holds related Azure resources which share the same lifecycle, permissions, and policies.

Key Points about Resource Groups:

• 🔄 Lifecycle Management:
  Manage deployment, updates, and deletions of all resources within a group as a single unit.
  Example: You can delete an entire resource group to remove all associated resources like VMs, storage, and networking components together.

• 📂 Resource Organization:
  Organize resources based on projects, environments (e.g., dev, test, prod), or applications for better clarity and control.
  Example: Group all resources for a web application in a “WebApp-Prod” resource group.

• 🔐 Role-Based Access Control (RBAC):
  Apply permissions and access policies at the resource group level to control who can manage or modify resources inside it.
  Example: Assign the “Contributor” role to developers only on the “Dev” resource group, limiting their access to production resources.

---

Azure Resource Manager (ARM) Overview

Definition:
Azure Resource Manager is the deployment and management service for Azure resources. It provides a consistent management layer allowing declarative, repeatable resource provisioning.

Key Features of Azure Resource Manager:

• 📄 Template-Based Deployment:
  Use JSON-based ARM templates to describe and deploy your infrastructure and configurations consistently.
  Example: Deploy an entire environment—including VMs, databases, and networking—in one automated deployment using a single ARM template.

• 🔗 Dependency Management:
  ARM automatically manages dependencies between resources, ensuring they deploy in the correct sequence.
  Example: ARM ensures a virtual network is created before deploying VMs that connect to it.

• ↩️ Rollback and Roll-forward:
  If deployment fails, ARM can automatically roll back to the previous stable state or roll forward to a known good configuration.
  Example: Prevent partial deployment issues by reverting changes if an error occurs during resource provisioning.

• 🏷️ Tagging and Categorization:
  Add tags (key-value pairs) to resources for better categorization, billing, and management.
  Example: Tag all resources used by the marketing team with Department=Marketing for cost tracking.

---

Note: Understanding how to work with Azure resources, organize them into resource groups, and automate deployment using Azure Resource Manager is essential for efficient cloud infrastructure management.
