Storage and Data Management

Storage and data management are crucial aspects of Azure, and you should be prepared to answer questions related to these topics:

1. What is the difference between an Azure storage account and an Azure file share?
   An Azure storage account is a cloud-based storage solution that provides scalable and durable storage for various data types, such as blobs, tables, queues, and files. An Azure file share is a network file share hosted in Azure and accessible via the Server Message Block (SMB) protocol, stored within an Azure storage account.

2. How can you secure data in Azure storage accounts?
   You can secure data in Azure storage accounts by using encryption (Azure Storage Service Encryption or client-side encryption), access control (shared access signatures or Azure AD authentication), and monitoring (Azure Storage Analytics).

3. What is Azure Blob Storage, and what are its use cases?
   Azure Blob Storage is a service for storing unstructured data, such as images, videos, and large files. It is commonly used for serving content, data backup, and storing application data.

4. How can you configure and manage storage in Azure?
   To configure and manage storage in Azure, you can create and manage storage accounts, choose the appropriate storage account type (Blob, File, etc.), set up data replication, manage access using Azure AD and RBAC, monitor performance and usage, and scale storage as needed.

Virtual Machines and Networking

Virtual machines and networking are core components of Azure, and you should expect questions related to these topics:

1. What are the steps to deploy a virtual machine in Azure?
   The steps to deploy a virtual machine in Azure include creating a resource group, creating a virtual network and subnet, creating a public IP address and network security group, creating the virtual machine (selecting the appropriate VM size, disk type, and operating system), and configuring any necessary network settings.

2. What are availability sets, fault domains, and update domains in Azure?
   Availability sets are logical groupings of virtual machines that help Azure understand how your application is built for redundancy and availability. Fault domains are logical groups of underlying hardware that share a common power source and network switch, while update domains are logical groups of hardware that can be rebooted or updated at the same time.

3. How can you secure virtual machine communication in Azure?
   You can secure virtual machine communication in Azure by using virtual networks, network security groups (NSGs), and Azure Bastion for secure remote access. Additionally, you can implement Azure VPN Gateway or Azure ExpressRoute for secure hybrid connectivity between on-premises and Azure resources.

4. What is Azure Load Balancer, and how does it work?
   Azure Load Balancer is a service that distributes incoming traffic among healthy virtual machines or other resources in a load-balanced set. It helps improve application availability and scalability by distributing traffic across multiple resources.

Azure Services and Solutions

Azure offers a wide range of services and solutions, and you should be prepared to demonstrate your knowledge in this area:

1. What is Azure App Service, and what are its benefits?
   Azure App Service is a platform-as-a-service (PaaS) offering that enables you to build, deploy, and manage web applications and APIs. Its benefits include automatic scaling, built-in load balancing, and support for multiple programming languages.

2. What is Azure Kubernetes Service (AKS), and what are its use cases?
   Azure Kubernetes Service (AKS) is a managed Kubernetes service that simplifies the deployment, management, and operations of Kubernetes clusters in Azure. It is commonly used for deploying and managing containerized applications at scale.

3. What is Azure Backup, and how does it work?
   Azure Backup is a cloud-based backup solution that helps protect data and applications by creating backups and storing them in the Azure cloud. It supports various data sources, including on-premises servers, Azure VMs, and files and folders, and offers features like backup scheduling, retention policies, and data recovery.

4. What is Azure Monitor, and how can it help with monitoring and logging?
   Azure Monitor is a comprehensive monitoring service that helps you collect, analyze, and act on telemetry data from Azure resources and on-premises environments. It provides features like application insights, log analytics, and activity logs to monitor the performance, availability, and health of your Azure resources.

Scenario-based Questions

In addition to theoretical questions, you may encounter scenario-based questions that test your ability to apply your knowledge to real-world situations. Here are a few examples:

1. You need to ensure that virtual machines remain available while migrating to Azure. What would be the appropriate service to use?
   In this scenario, you should consider using Azure ExpressRoute, which provides a dedicated private network connection between your on-premises environment and Azure. This ensures that your virtual machines remain available during the migration process.

2. You need to isolate network traffic among virtual machines in a subnet, which is part of a virtual network, with minimal downtime and impact on users. How would you handle this?
   To isolate network traffic among virtual machines in a subnet, you can create a network security group (NSG) and apply it to the subnet. NSGs allow you to filter inbound and outbound traffic based on rules you define, enabling you to isolate traffic without impacting users.

3. You need to ensure that every time a user logs in, they are not asked to re-enter their passwords as part of the authentication process. How would you handle this?
   In this scenario, you should configure Azure AD Sync to enable single sign-on (SSO). With SSO, users can log in once and gain access to all authorized resources without being prompted to log in again for each application or service.

4. Your standard tier application is used across the world and uses the Azure website standard tier. It uses a large number of image files, causing the application to load slowly. How would you optimize the application’s performance?
   To optimize the application’s performance in this scenario, you should consider configuring Azure Content Delivery Network (CDN) to cache site images and content stored in Azure Blob Storage. By caching frequently accessed content closer to users, CDN can significantly improve the application’s load times and overall performance.

By thoroughly preparing for these AZ-104 interview questions and understanding the underlying concepts, you’ll be well-equipped to showcase your Azure expertise and increase your chances of success in the interview process.
