What is Azure Resource Manager (ARM)?
Azure Resource Manager (ARM) is the deployment
and management service in Azure that allows you to create, manage, and organize
resources in a declarative manner. It provides a consistent management layer and
enables you to deploy and manage resources as a group, known as an ARM template.
How can you scale an Azure Web App?
Azure Web Apps can be scaled vertically and
horizontally. Vertical scaling involves changing the size of the virtual machine
instance associated with the web app, while horizontal scaling involves increasing
or decreasing the number of instances running the app.
Question: What are Azure Functions and when would you use them? Answer: Azure
Functions is a serverless computing service in Azure that allows you to run
event-driven code without managing the underlying infrastructure. It is ideal for
executing small pieces of code in response to events, such as data changes, timer
triggers, or HTTP requests.
How can you secure data in Azure Storage?
Azure Storage provides several security
features to protect data, such as encryption at rest using Azure Storage Service
Encryption (SSE), encryption in transit using SSL/TLS, and shared access signatures
(SAS) for fine-grained access control.

Explain the difference between Azure SQL Database and
Azure SQL Managed Instance.
Azure SQL Database is a fully managed,
scalable, and intelligent relational database service in Azure. It is suitable for
modern cloud applications. On the other hand, Azure SQL Managed Instance provides a
fully managed instance of SQL Server in Azure with native virtual network (VNet)
integration. It is designed for migrating on-premises SQL Server workloads to Azure.
How would you optimize the performance of an Azure
virtual machine?
The candidate should mention techniques such as
selecting the appropriate virtual machine size, optimizing disk I/O, using managed
disks, leveraging caching mechanisms, and implementing auto-scaling based on
resource utilization.
Suppose an Azure virtual machine is experiencing high
CPU usage. How would you troubleshoot and resolve the issue?
The candidate should mention steps like
analyzing performance metrics, identifying resource-intensive processes, optimizing
code or configurations, increasing the VM size, or adding additional VM instances.
You need to deploy a highly available web application
in Azure. What services and configurations would you use to achieve this?
The candidate should mention using Azure App
Service with multiple instances or Azure Kubernetes Service (AKS) for containerized
applications, configuring load balancing, setting up Azure Traffic Manager for
global load balancing, and implementing Azure Front Door for application-level
routing and failover.
How would you implement automated backups for an Azure
SQL Database?
The candidate should mention utilizing Azure
SQL Database's automated backups feature, which creates regular backups and retains
them based on the defined retention period. They should also mention setting up
long-term retention using Azure Backup or exporting backups to Azure Blob storage.
What steps would you take to secure an Azure virtual
network?
The candidate should mention strategies like
implementing network security groups (NSGs) to control inbound and outbound traffic,
using virtual network service endpoints and private endpoints, configuring network
security appliances or virtual appliances, and enabling Azure DDoS Protection.
Describe a challenging project you worked on as an
Azure developer. How did you overcome the difficulties?
The candidate should provide an example of a
complex Azure project they were involved in, describe the specific challenges faced,
and explain the actions they took to overcome those challenges. This question
evaluates problem-solving skills and resilience.
Can you tell us about a time when you had to
collaborate with cross-functional teams to deliver an Azure solution?
The candidate should share an experience where
they collaborated with individuals from different teams or departments to achieve a
common goal. They should highlight their communication skills, teamwork, and ability
to navigate diverse perspectives.
How do you stay updated with the latest Azure features
and best practices?
The candidate should mention their approach to
continuous learning, such as following Microsoft documentation and blogs, attending
webinars or conferences, participating in online communities, or engaging in
personal projects to explore new Azure features.
Describe a situation where you had to prioritize
multiple Azure projects with tight deadlines. How did you manage your time and
ensure successful delivery?
The candidate should share a scenario where
they had to juggle multiple Azure projects simultaneously. They should explain their
time management techniques, delegation strategies, and how they ensured timely
completion of tasks without compromising quality.
Tell us about a time when you encountered an
unexpected issue during an Azure deployment or migration. How did you handle it?
The candidate should describe a real-life
scenario where they faced an unforeseen problem during an Azure deployment or
migration. They should explain their troubleshooting approach, ability to think on
their feet, and how they resolved the issue while minimizing disruption.
