Top 20 Azure Cloud Administrator Interview Questions and Answers

Q1. What experience do you have with Azure Resource Manager?

This commonly asked question tests your hands-on expertise with Azure Resource Manager which is critical for provisioning and managing Azure resources.

Tips for answering:

• Demonstrate your experience with using Resource Manager to deploy, organize and control Azure resources.
• Highlight how you used features like templates, access control (RBAC), tags, resource groups etc.
• Give examples of real-world scenarios where you used Resource Manager to provide value.

Sample Answer:

I have used Azure Resource Manager extensively for provisioning and managing our cloud environment. Key ways I’ve used it are:

• Setting up resource groups to logically organize related resources like VMs, storage, networking. This helps manage them as a single unit.

• Building and deploying ARM templates to automate provisioning of resources for faster setup. We use templates for our test environments and production deployments.

• Implementing RBAC to control access to resources. I set customized roles and permissions for our dev and ops teams.

• Tagging resources like VMs, storage, subnets to make them easier to search and manage. Common tags I’ve used are Environment, Department etc.

Overall, Resource Manager has enabled our team to quickly spin up new environments and scale resources while enforcing standards through templatized deployments.

Q2. How would you monitor and troubleshoot virtual machines in Azure?

This questions tests your monitoring and troubleshooting know-how for Azure virtual machines which are commonly used to run applications and workloads.

Tips for answering:

• Demonstrate your expertise with using native Azure tools like Monitor, Log Analytics, Network Watcher etc.
• Provide a structured approach to troubleshooting VM issues from identification to resolution.
• Give real examples of VM issues you have diagnosed and fixed.

Sample Answer:

My approach for monitoring VMs would be:

• Enabling Azure Monitor diagnostic logs and metrics like CPU%, memory, disk queue depth. Setting up alerts for critical metrics.

• Using Log Analytics to monitor performance trends, analyze logs, create dashboards.

• Viewing network traffic logs and metrics through Network Watcher for any anomalies.

For troubleshooting, I would first isolate the issue and then drill down to root cause:

• Check Resource Health status for any known VM issues or degradation.

• Use Performance Diagnostics to identify probable bottleneck – CPU, network or disk.

• Verify application logs and processes for errors. Restart processes/app if needed.

• If degraded network performance, use NSG flow logs in Network Watcher to analyze traffic.

• For disk issues, look at disk metrics in Monitor and Storage Analytics.

For example, I once fixed sluggish performance by analyzing metrics in Monitor which revealed a saturated disk queue. Adding more data disks fixed it.

Q3. What strategies and tools would you use to migrate servers to Azure?

This questions tests your expertise with migrating on-premises servers/VMs to Azure, which is one of the key responsibilities of an Azure admin.

Tips for answering:

• Demonstrate migration strategies you have used – lift-and-shift, rehosting, refactoring.
• Highlight relevant tools and services like Azure Migrate, Site Recovery, Data Factory etc.
• Provide an overview of the migration process from assessment to execution.

Sample Answer:

For migrating servers to Azure, I leverage a structured approach:

First, I would use Azure Migrate to assess on-prem servers for readiness – compatibility, performance, scaling needs etc.

For actual migration, some strategies I’ve used are:

Lift-and-shift – Quickly migrate VMs as-is using Site Recovery. Minimizes downtime.

Rehosting – Migrate VMs and optimize configurations like VM size, storage.

Refactoring – Rebuild apps natively on cloud like Azure App Service.

Key tools I leverage are:

• Site Recovery for agentless replication and failover of VMs.

• Azure Database Migration Service to migrate SQL databases to Azure SQL.

• Data Factory to migrate data from on-prem data sources.

• Azure Migrate Server Assessment and Server Migration tools for discovery, assessment and migration.

By following a phased approach, we can migrate on-prem workloads smoothly while optimizing them for the cloud.

Q4. How do you optimize costs for Azure environments?

This question tests your proficiency with optimizing costs for Azure environments which is crucial for keeping cloud spending in check.

Tips for answering:

• Demonstrate cost optimization strategies you have implemented – resource tagging, right-sizing, Purchase Plans, scaling etc.
• Highlight Azure tools you have used – Cost Management, Advisor, resource alerts.
• Quantify savings you have achieved for organizations.

Sample Answer:

Optimizing cloud costs is a priority for me. Some ways I have optimized costs are:

• Analyzing usage and expenditure by resource group and tags using Cost Management. Identifying waste.

• Right-sizing underutilized VMs using Advisor recommendations. This reduced costs by around 20% in one project.

• Setting up auto-shutdown for dev/test VMs on schedules using Azure Automation.

• Leveraging Purchase Plans to get volume discounts for production workloads.

• Setting up Action Groups and budget alerts to notify on cost thresholds.

• Implementing auto-scaling of resources based on demand. This cut excessive spending due to overprovisioning.

• Providing cost visibility to teams through chargeback reports. This helped reduce spending by promoting accountability.

Through these efforts I have been able to optimize cloud costs by 25-30% while delivering business value.

Q5. How would you ensure high availability for applications in Azure?

This questions gauges your skills and knowledge of providing HA for apps on Azure – a critical responsibility.

Tips for answering:

• Demonstrate high availability design principles and features you have used – redundancy, scaling, failover.
• Highlight relevant Azure services for HA like Load Balancer, Availability Sets, Availability Zones etc.
• Provide examples of HA implementations.

Sample Answer:

Some ways I architect highly available applications on Azure are:

• Using Availability Zones to distribute VMs across isolated data centers within a region. Protects from data center level failures.

• Implementing Availability Sets with VMs spread across fault/update domains. Makes VMs resilient through redundancy.

• Load balancing traffic across multiple VM instances to absorb spikes in demand.

• Enabling autoscaling on resources like App Service and VMs to scale out dynamically based on load.

• Using Traffic Manager for fast failover across regions when a region goes down.

• Implementing a RAID array for data disks to mitigate disk failures.

• Regularly backing up data to alternate regions using Geo-redundant Storage.

• Testing HA by simulating different failure scenarios.

For example, for a e-commerce site, I deployed VMs across zones combined with regional Traffic Manager failover. This delivered continuous uptime through a zone outage.

Q6. What techniques and tools
