Top 20 Azure Interview Questions | Software Courses in Chennai
If you are preparing for an Azure Administrator interview in 2026, memorising definitions alone will not be enough. Interviewers increasingly ask candidates to explain how they would configure, monitor, secure, troubleshoot, and optimise Azure resources in a real environment.
Microsoft’s AZ-104 administrator learning path focuses on identity and governance, storage, compute, networking, monitoring, and backup, which closely matches the areas commonly seen in current interview-preparation material.
This guide covers 20 Azure Administrator interview questions with answers, including Virtual Machines, Microsoft Entra ID (formerly Azure Active Directory), Azure SQL Database, VNets, NSGs, Azure Monitor, backup, RBAC, and cost optimisation.
For freshers and job seekers, the important thing is not just knowing what an Azure service does. Try to explain why you would use it, how you would configure it, and how you would troubleshoot it.
What Interviewers Look for in an Azure Administrator
An Azure Administrator is expected to provision, manage, monitor, and adjust cloud resources. Microsoft specifically identifies identity, governance, virtual networking, compute, monitoring, and backup as core administrator responsibilities.
That means an interview can move quickly from a basic question such as “What is a VNet?” to a scenario like “A VM cannot connect to a database. How would you troubleshoot it?”
A good answer should therefore follow a simple pattern:
Identify the problem → check configuration → use Azure diagnostic tools → make the smallest safe change → verify the result.
Top 20 Azure Administrator Interview Questions
1. What is Microsoft Azure?
Answer: Microsoft Azure is a cloud computing platform providing services for compute, storage, networking, databases, identity, monitoring, security, and application development. An Azure Administrator manages these resources according to organisational requirements.
2. What is a Resource Group in Azure?
Answer: A Resource Group is a logical container for related Azure resources. Resources can be managed, monitored, tagged, and given access permissions at the resource-group level. A well-designed resource-group structure also makes administration and cost tracking easier.
3. What is Microsoft Entra ID?
Answer: Microsoft Entra ID is Azure's cloud-based identity and access management service. It manages users, groups, applications, authentication, and access policies. It was formerly known as Azure Active Directory.
For Azure SQL, Microsoft Entra authentication can centralise identity and permission management rather than relying only on individual database usernames and passwords.
4. What is Azure RBAC?
Answer: Azure Role-Based Access Control allows administrators to control what users can do with Azure resources. Roles such as Reader, Contributor, and Owner can be assigned at different scopes, including management group, subscription, resource group, or resource.
Interview tip: Mention least privilege and appropriate scope.
5. What is an Azure Virtual Machine?
Answer: An Azure VM is an Infrastructure-as-a-Service resource that provides a virtualised Windows or Linux server. Administrators can select its operating system, VM size, disks, networking, security settings, and availability configuration.
6. How would you troubleshoot a VM that is running slowly?
Answer: Start by checking CPU, memory, disk performance, and network metrics. Then review Azure Monitor metrics and activity logs. Check whether the VM size is appropriate, whether disks are causing a bottleneck, and whether recent configuration changes caused the issue.
7. What is an Azure Virtual Network?
Answer: Azure Virtual Network, or VNet, provides private networking for Azure resources. It contains address spaces and subnets and can connect Azure resources with other networks through services such as VPN Gateway or ExpressRoute.
8. What is an NSG?
Answer: A Network Security Group controls inbound and outbound network traffic using security rules. NSGs can be associated with subnets or network interfaces. Rules evaluate traffic according to priorities and allow or deny specified connections.
9. How would you troubleshoot connectivity between two Azure VMs?
Answer: Check the VNet and subnet configuration first. Then review NSG rules, route tables, firewall settings, DNS, and VM-level configuration. Azure Network Watcher can be used for connectivity diagnostics and other network troubleshooting.
10. What is Azure SQL Database?
Answer: Azure SQL Database is Microsoft's managed relational database service based on the SQL Server engine. Microsoft manages much of the underlying infrastructure, allowing teams to focus more on databases and applications.
Security features include encryption, auditing, Microsoft Entra integration, and network controls.
11. How can an application securely connect to Azure SQL?
Answer: The administrator should consider network controls, authentication, authorisation, and encryption. Microsoft Entra authentication can provide centralised identity management, while firewall and networking controls restrict connectivity.
12. What is Azure Monitor?
Answer: Azure Monitor collects and analyses telemetry from Azure and other environments. Administrators can use metrics, logs, dashboards, Log Analytics, and alerts to investigate resource health and performance. Log Analytics supports querying collected logs using KQL.
13. How do Azure Monitor alerts work?
Answer: An alert rule watches a selected signal, such as a metric, log query, or activity-log event. When configured conditions are met, Azure Monitor can trigger an action such as an email, notification, or automated response.
14. What is Azure Backup?
Answer: Azure Backup provides backup capabilities for supported Azure and hybrid workloads. A typical answer should mention backup policies, retention, Recovery Services vaults where applicable, and regularly testing restoration rather than assuming that a backup automatically guarantees recoverability.
15. What is the difference between Availability Sets and Availability Zones?
Answer: Availability Sets distribute VMs across fault and update domains within a datacenter environment, while Availability Zones provide physically separate locations within an Azure region. Zones are designed to provide stronger isolation against datacenter-level failures.
16. How would you investigate an unexpected VM restart?
Answer: Check the Azure Activity Log, VM boot diagnostics, operating-system event logs, Azure Monitor metrics, and recent maintenance or configuration changes. The objective is to determine whether the restart was caused by an Azure platform event, administrator action, operating-system issue, or application problem.
17. How do you control Azure costs?
Answer: Start with Cost Management, budgets, tags, and regular cost analysis. Then identify idle or underutilised resources, right-size VMs, remove unused resources, and review Azure Advisor recommendations. Microsoft specifically recommends reviewing utilisation and VM sizing as part of cost optimisation.
18. What is Azure Advisor?
Answer: Azure Advisor analyses Azure environments and provides recommendations across areas such as cost, reliability, security, and operational efficiency. For example, it can identify underutilised VMs and recommend resizing or shutting them down.
19. A production VM cannot be accessed. What would you check first?
Answer: Do not immediately restart the VM. First check its status, recent Activity Log events, networking, NSGs, public/private IP configuration, routes, DNS, and firewall settings. Use Azure diagnostics such as Network Watcher where appropriate. Then determine whether the issue is network-level, OS-level, or platform-related.
20. How would you answer a real-world Azure troubleshooting question?
Answer: Explain your troubleshooting sequence rather than jumping directly to a fix. For example:
Check symptoms → identify affected resource → review metrics/logs → verify configuration → isolate the fault → apply the least disruptive fix → monitor the result.
This approach demonstrates practical administration skills rather than memorised Azure definitions.
Quick Takeaways
AZ-104 knowledge is highly relevant to Azure Administrator interview preparation.
Be comfortable with VMs, VNets, NSGs, Microsoft Entra ID, RBAC, Azure SQL, monitoring, and backup.
Scenario questions often test your troubleshooting process, not just definitions.
Learn to use Azure Monitor and Network Watcher when explaining diagnostics.
Understand Cost Management and Azure Advisor, not only technical configuration.
For Azure SQL, know the basics of authentication, networking, authorisation, and encryption.
Freshers should build small Azure labs so they can explain what they have actually configured.
How to Prepare for an Azure Administrator Interview
A useful preparation strategy is to divide your learning into four areas: identity, infrastructure, networking, and operations.
Start with Microsoft Entra ID and RBAC. Then practise creating a VM, attaching disks, configuring a VNet and subnet, applying an NSG, and monitoring the VM.
Next, create an Azure SQL Database and understand how an application could connect to it securely. Finally, practise creating monitoring alerts and analysing logs.
This hands-on approach is particularly useful for Azure Administrator interview questions for freshers, because it gives you practical examples to discuss instead of only textbook definitions.
