Microsoft Azure Fundamentals (AZ-900) Practice Exam 2026 actual
questions and well detailed answers
Question 1
What is the primary benefit of High Availability in cloud computing?
• A. Lowering the total storage cost per gigabyte.
• B. Ensuring that services remain operational even if a component or region
experiences a failure.
• C. Automatically increasing processing power during peak workloads.
• D. Encrypting data at rest by default.
• Correct Answer: B
• Explanation: High availability ensures that systems can run continuously for
a desired length of time without significant downtime by deploying
redundant components.
Question 2
Which cloud deployment model consists of cloud resources exclusively used by a
single business or organization, hosted on-premises or managed by a third
party?
• A. Public Cloud
• B. Private Cloud
• C. Hybrid Cloud
• D. Multi-cloud
• Correct Answer: B
• Explanation: A private cloud is operated solely for a single organization,
providing greater control and security.
Question 3
What is Capital Expenditure (CapEx) in the context of cloud computing
economics?
,Microsoft Azure Fundamentals (AZ-900) Practice Exam 2026 actual
questions and well detailed answers
• A. An ongoing operational expense for consuming cloud services as you go.
• B. An upfront investment in physical infrastructure such as datacenters,
servers, and hardware.
• C. The cost of technical support subscriptions billed monthly.
• D. Bandwidth consumption fees based on outbound internet traffic.
• Correct Answer: B
• Explanation: CapEx involves an upfront financial investment in physical
infrastructure, whereas cloud computing typically shifts costs to OpEx
(Operational Expenditure).
Question 4
Which characteristic of cloud computing allows resources to scale up or scale
down automatically based on fluctuating demand?
• A. High Latency
• B. Elasticity
• C. Capital Expenditure
• D. Single Tenancy
• Correct Answer: B
• Explanation: Elasticity is the ability of a cloud system to automatically or
dynamically add or remove resources based on workload demands.
Question 5
What is the primary advantage of using a multi-cloud strategy?
• A. Eliminates all cloud billing charges.
• B. Avoids vendor lock-in by distributing workloads across multiple cloud
providers.
• C. Reduces internet bandwidth requirements to zero.
,Microsoft Azure Fundamentals (AZ-900) Practice Exam 2026 actual
questions and well detailed answers
• D. Requires only one vendor contract for all services.
• Correct Answer: B
• Explanation: A multi-cloud approach prevents dependency on a single
cloud provider and allows organizations to leverage best-of-breed services
from different providers.
Question 6
Which cloud service model provides a complete development and deployment
environment allowing developers to build applications without managing
underlying infrastructure?
• A. Infrastructure as a Service (IaaS)
• B. Platform as a Service (PaaS)
• C. Software as a Service (SaaS)
• D. Desktop as a Service (DaaS)
• Correct Answer: B
• Explanation: PaaS provides developers with managed platforms (like Azure
App Service or SQL Databases) to focus on application code rather than
virtual machines or networking hardware.
Question 7
In which cloud service model is the consumer responsible for operating system
patching, application configuration, and security updates?
• A. Software as a Service (SaaS)
• B. Platform as a Service (PaaS)
• C. Infrastructure as a Service (IaaS)
• D. Function as a Service (FaaS)
• Correct Answer: C
, Microsoft Azure Fundamentals (AZ-900) Practice Exam 2026 actual
questions and well detailed answers
• Explanation: With IaaS, Azure manages the physical datacenter, but the
customer retains full management responsibility for the guest OS, patches,
and applications.
Question 8
Microsoft 365 (formerly Office 365) is an example of which cloud service model?
• A. Infrastructure as a Service (IaaS)
• B. Platform as a Service (PaaS)
• C. Software as a Service (SaaS)
• D. Function as a Service (FaaS)
• Correct Answer: C
• Explanation: SaaS delivers fully functioning software applications over the
internet on a subscription basis.
Question 9
What is disaster recovery (DR) in cloud architecture?
• A. The process of backing up local computer files to a USB flash drive.
• B. The ability of an IT system to recover and resume operations after a
catastrophic event or disaster.
• C. The scheduling routine for applying weekly security patches.
• D. The method of reducing monthly cloud storage bills.
• Correct Answer: B
• Explanation: Disaster recovery involves policies, tools, and procedures to
enable the recovery or continuation of vital technology infrastructure
following a disaster.
