Azure Interview Questions and
Answers for Beginners

Cloud computing uses internet-based
computers to store, manage, and process
data. Rather than managing its own servers,
third-party companies such as Microsoft and
AWS provide and manage infrastructure for a
fee based on usage time. It improves speed,
ﬂexibility, and scalability while providing high
fault tolerance and system availability
dependent on application needs.
Q1.Describe Cloud Computing.?

Microsoft's Azure Cloud Service is a platform as a
service (PaaS) offering aimed at highly scalable,
dependable, and available applications at a low
operational cost. It makes use of virtual VMs, which
allow developers to remotely install and control
software. This service is perfect for deploying
multi-tier web applications, as it allows for the
creation of instances and the definition of roles such
as web or worker roles for distributed processing.
Each role in the cloud service has its own set of
configuration and application files, allowing for
simple and flexible scalability.
Q2. Describe the Azure Cloud Service concept.

There are three cloud deployment models
available:
1. Public Cloud: The cloud provider's public
cloud, with shared server resources across
several applications.
2. Private Cloud: Exclusively owned by us or
offered by the cloud provider. Applications
can be hosted on-premises or on a
dedicated server provided by the cloud
provider.
3. Hybrid Cloud: A hybrid of both public and
private clouds. It could entail deploying
on-premise servers for sensitive data
processing & leveraging public cloud
features for hosting public-facing
applications.
Q3. What are the various cloud deployment models available?

A role instance is nothing more than a virtual machine on which application code
executes with the assistance of running role configurations. A role can also have
numerous instances, as defined in the cloud service configuration files.
Q4. Explain an Azure role instance.

Cloud service roles are made up of a collection of application and conﬁguration ﬁles.
Azure offers two different types of roles:
1. Web role: This role provides a dedicated IIS (Internet Information Services) web
server for the automatic deployment and hosting of front-end websites.
2. Worker roles: These roles allow the programs hosted within them to run
asynchronously for longer periods of time, are independent of user interactions, and
do not typically use IIS.
Q5. How many different types of cloud service roles does Azure offer?

The Azure Diagnostics API collects diagnostic data from Azure apps, such as system
event logs and performance monitoring. For the cloud service roles, Azure Diagnostics
must be enabled. The acquired data can then be used to generate visual chart
representations for enhanced monitoring and performance metric warnings.
Q6. What is the purpose of the Azure Diagnostics API?

The SLA guarantees that access to your cloud service will be maintained at least 99.95
percent of the time when you send two or more role instances for each role.
Additionally, when a role instance's procedure isn't running, 99.9% of the time,
identiﬁcation and re-correction actions will be begun.
Q7. Explain the Service Level Agreement (SLA) for Azure.

Azure Resource Manager, a service provided by Azure, manages and deploys
applications in Azure. The management layer aids in the creation, modiﬁcation, and
deletion of resources in the Azure subscription account. It is useful for managing
access controls, locks, and resource security.
Q8. What is Azure Resource Manager and how does it simplify
resource management?

Network Security Groups, or NSGs, are groups with access control lists, or ACLs, that
contain a list of rules that either permit or prohibit network communication to
subnets, NICs (Network Interface Cards) connected to subnets, or both. All Virtual
Machines within a subnet that is linked to NSG are subject to the ACL rules.
Q9. What does Azure's NSG stand for?

False. This is not supported by Azure.
Q10. Is it accurate to say that in a virtual network established by traditional deployment,
virtual machines can be built using Azure Resource Manager?

Azure Redis Cache is
an in-memory Redis
cache technology
designed to enhance
performance for web
applications. Using the
Azure cloud, Azure
Redis Cache offers
strong and safe
caching technologies.
Q11. Explain Azure Redis Cache.

• Sets of identical Virtual Machines (VMs) can be
deployed and managed using these Azure
compute resources.
• These scale sets have the same conﬁguration and
are made to allow applications to autoscale
without requiring virtual machines to be
pre-speciﬁed.
• They facilitate the easier development of
large-scale applications aimed at containerized
workloads and big data.
Q12. Describe the scale sets of Azure virtual machines.

All that an availability set is is a logical
collection of virtual machines, or VMs, that
tells Azure Cloud how an application was
designed to be available and redundant.
Azure gives you the freedom to set up as
many as 20 update domains and three
fault domains for each availability set.
Azure gives each virtual machine in the
availability set one of two types of
domains:
1. Update Domain
2. Fault Domain
Q13. What do you know about Azure's "Availability Set"?

Two deployment environments exist:
1. Staging environment: This is where modiﬁcations to an application are tested before
going live.
2. Production environment: Target users can access applications in this environment using
a DNS-friendly URL after they become live.
Q14. What choices are there for Azure's deployment environments?

The actions listed below must be taken in the event of a drive failure:
● To guarantee that Azure Storage runs ﬂawlessly, make sure the drive is not
mounted.
● Change out the drive remount and format it.
Q15. What actions need to be performed in the event that an Azure drive fails?

Certainly, the Transient Fault Handling Block makes it feasible. Periodic
application-to-database connection failures with more load balancers, slower calls,
and timeouts in multi-tenant services, or the frequent user hit resulting in purposeful
connection denial to support other tenants in the architecture can all be causes of
transient failures in the cloud.
Q16. Are you able to create Azure applications that can deal with connection failures?

Depending on the needs of the project, an Azure storage key is used to authenticate
access to data stored on Azure storage services. Two categories of storage keys are
used in authentication:
1. Primary access key
2. Secondary access key, to prevent website or application downtime
Q17. Define an Azure storage key.

A command-line utility called CSPack creates the service package file and gets an
application ready for Compute Emulator or Azure deployment. The cloud service
configuration file, or .cscfg file, created with CSPack, is included in every project
including cloud services. It keeps:
● The number of role instances in each deployment for each role
● Thumbprints on the certificates
● Configurations that are defined by the user
Q18. What is cspack and how does Azure use it?

Serverless code execution is made possible by Azure Functions, which makes
intricate orchestration and resolution easier. They eliminate the need for hard-coded
integrations by facilitating smooth connections with other services through their
stateless and transient design. With this method, work is sped up and developers
can concentrate on writing business logic code. Furthermore, Azure Functions
provide performance analysis and monitoring capabilities via Azure Application
Insights, which help locate bottlenecks and sites of failure in the application
components.
Q19. Which Azure option works best for code execution without a server?

The Azure File System serves as a single repository for exchanging data between
virtual machines that are set up with protocols like SMB, FTP, NFS, and so on.
Q20. Which Azure function is suggested for a shared file-sharing setup
amongst several virtual machines?

Answers for Intermediate

It is feasible to access another virtual machine (VM) without requiring a
password by utilizing the Key Vault mapping to any Admin VM.
Q21. Is it feasible to access an Azure Linux virtual machine without
entering a password?

Q22. How do Azure Scale Sets and Availability Sets differ from one
another?
Azure Scale Sets Azure Availability Sets
They are a collection of virtual machines
with the same configuration dispersed
among several fault domains.
They are the collection of individually
configured virtual machines dispersed
among different fault domains.
These by default update domains and have
five fault domains.
These come with three fault domains and
five update domains by default.
These are used when unpredictable
workloads necessitate the auto-scaling
capability.
When workload requirements are
predictable, these are used.
In this case, the virtual machines are set up
and made using the same picture in the
same way.
Here, various images and parameters are
used to construct the virtual machines
(VMs).
Depending on demand or the
predetermined timetable, the number of
virtual machines (VMs) can be changed.
An availability set can only have VMs
added to it at the time the set is created.
In this case, the VM scale sets may be split
up over several data centers or contained in
a single data center.
Here, a data center's virtual machines are
distributed automatically.
The following lists the primary
distinctions between Azure Scale Sets
and Availability Sets:

Depending on the protocol that analyses the password that was input and the IP
address that the login request was made from the Azure account will be locked
in this case.
Q23. What occurs when the number of unsuccessful tries during
Azure ID authentication is reached?

No. Only private IP addresses are supported by Azure Internal Load Balancer.
Q24. Is it possible to get the Azure Internal Load Balancer's
public DNS or IP address?

The cloud's solution for object storage is Azure Blob (binary huge object)
storage. It can be used to provide documents, media, or text straight to the
browser and can store enormous amounts of unstructured data in binary or text
format. You can access the data from any location. The blobs are associated
with user accounts and arranged into containers. There are three parts to this
service:
1. Storage account
2. Container
3. Blob
Q25. Describe the concept behind Azure Blob Storage.

With Azure Scheduler, we can call speciﬁc
background trigger events or actions on
demand, such as displaying a message on
the queue or contacting HTTP/S endpoints.
The jobs that are present in the cloud call
services both inside and outside of Azure can
be scheduled to start at a future date or to
run on-demand according to a regular
schedule by using this Azure Schedule.
Q26. Describe Azure Scheduler and explain how to use it

In Azure, you may achieve this by creating a different load balancer role.
Q27. Can a Windows computer running on a separate port be
mapped to an Azure load balancer?

By using Azure VM Scale Sets to conﬁgure conditions for creating new VMs
when the application load grows, you may address this issue.
Developer-managed scale settings that allow load-balanced virtual machine
groups to be created. High availability is ensured by automatic scaling based on
application demand or a preset timetable. Large virtual machines (VMs) may be
more easily managed, updated, and conﬁgured centrally, which helps developers
create applications with high data, workload, and compute requirements. When
utilizing custom images, the maximum number of virtual machines (VMs) that
Azure scale sets can support is 1,000.
Q28. When there is no manual help available, which Azure feature can be used to
manage heavy application loads?

In addition to Blob storage, table storage, queue storage, and file storage,
Azure provides three more categories of storage services.
1. Azure table storage: This NoSQL-based key-value store enables the
development of applications using semi-structured data.
2. Azure queue storage: By creating robust and adaptable applications,
the message queue system can manage heavy workloads.
3. Azure file storage: SMB (server message block) protocol is used to
provide file access and sharing. SMB 3.0 and HTTPS are used to
safeguard the data.
Q29. What other kinds of storage services does Azure offer
besides blob storage?

● IaaS: Infrastructure as a Service is shortened to IaaS. It
provides a number of infrastructure-level functions, like
OS and network connectivity. It operates on a pay-per-use
basis. It serves as an application host. Examples of this
kind of infrastructure are Azure VM and VNET.
● PaaS: Platform as a Service, or PaaS, is an abbreviation.
Its main feature is the abstraction of the underlying
infrastructure, which enables faster application
development without the burden of hosting management.
PaaS includes things like storage services, cloud services,
Azure web apps, etc.
● SaaS: Software as a Service is referred to as SaaS. These
apps are provided under a service delivery paradigm in
which an organization only uses the applications. SaaS
comes after advertising or subscription-based pricing.
SaaS examples include Oﬃce 365, Gmail, SharePoint
Online, and so forth.
Q30. Describe Azure's IaaS, PaaS, and SaaS offerings.

Q31.What distinguishes Azure SQL service from Azure Table
Storage?
Table Storage Service Azure SQL Table
This uses Azure's NoSQL storage
model.
It is organized according to Azure's relational
storage model.
This data is called an entity and is
kept in key-value format.
Here, the data is kept in an SQL table in a
combination of rows and columns.
For storage, the data schema is
not required.
When a schema violation happens, an error is
produced because the data schema is strictly
followed for data storage.
It is not possible for tables to be
related to one another.
Foreign keys are used to deﬁne relationships
between tables.
Each entity's partition and row key
combination are thought to be
distinct.
A primary key or unique key can be used by the
user to deﬁne uniqueness.
You can store diagnostics data or
log information using this service.
Applications that rely on transactions frequently
use this service.

● For a limited number of resources, link an on-premise database to an Azure-hosted
application by using the Azure VNET-based "Point to Site" service.
● Take "Site to Site" or "Express Routes" into consideration if you have a lot of
resources.
● Although "Site to Site" VPN connections may result in network latency, "Express
Routes" offer a dedicated leased line to circumvent this problem.
● Create an on-premise Windows Communication Foundation (WCF) service and host
CRUD activities only for the on-premise database if the customer would rather not
operate via VNET.
● For database access, use the "Service bus relay" option to facilitate communication
between the WCF service and the Azure-hosted application.
Q32. How can connectivity be managed in Azure when the database must be
on an on-premise server due to security concerns and the application front
end is hosted there?

Q33. What are the various causes of a client application getting
disconnected from the cache?
There are two potential reasons:
1. Causes on the client side: It's possible that the application was
redeployed. It could have just been a scaling procedure by the
application. There have been changes to the client-side
networking layer. There could be momentary problems with the
client or the network connecting the client and server. Another
cause can be that the bandwidth threshold restrictions have
been exceeded.
2. Causes on the server: It could happen if there is a failover from
the primary to the secondary node in the Azure Redis Cache
service itself. It's possible that maintenance or patches were
applied to the server instance where the cache was installed.
