1. A company wants to migrate its on-premises servers to the cloud to reduce capital
expenditure (CapEx) and shift to an operational expenditure (OpEx) model. Which cloud
computing benefit does this represent?
A. High Availability
B. Economies of Scale
C. Consumption-based model
D. Reliability
Rationale: The consumption-based model allows organizations to pay only for the resources
they use, effectively shifting costs from upfront capital investment to variable operational
expenses.
2. Which of the following is an example of Infrastructure as a Service (IaaS)?
A. Microsoft 365
B. Azure SQL Database
C. Azure Virtual Machines
D. Azure App Service
Rationale: IaaS provides the highest level of flexibility and management control over IT
infrastructure. Azure Virtual Machines allow you to manage the operating system and
installed software, typical of IaaS.
3. What is the primary purpose of an Azure Region?
A. To provide a physical location for data centers to ensure low latency and regulatory
compliance.
B. To act as a billing entity for different departments.
C. To provide a virtual network isolation layer.
D. To replicate data globally for backup purposes only.
Rationale: Azure regions are sets of data centers deployed within a latency-defined perimeter,
enabling global reach while meeting data residency and regulatory requirements.
4. You need to ensure that your Azure resources are deployed only in specific geographical
areas to comply with data privacy laws. Which feature should you use?
A. Azure Policy
B. Resource Groups
,C. Azure Subscriptions
D. Management Groups
Rationale: Azure Policy allows you to define rules and effects for your resources, such as
restricting the locations where resources can be deployed to ensure compliance.
5. Which service should you use to run containerized applications without managing the
underlying virtual machines?
A. Azure Virtual Machines
B. Azure Container Instances
C. Azure Disk Storage
D. Azure Batch
Rationale: Azure Container Instances (ACI) is a serverless offering that allows you to run
containers directly in Azure without having to manage the host virtual machines or
orchestrators.
6. Which Azure service is designed to manage the identity and access of users across cloud
applications?
A. Azure Active Directory (Microsoft Entra ID)
B. Azure Key Vault
C. Azure Firewall
D. Azure Monitor
Rationale: Microsoft Entra ID (formerly Azure AD) is the cloud-based identity and access
management service that helps employees sign in and access internal and external resources.
7. A developer wants to host a web application and wants Azure to handle the scaling and
infrastructure maintenance automatically. Which service is most appropriate?
A. Azure Virtual Machines
B. Azure App Service
C. Azure Functions
D. Azure Cosmos DB
Rationale: Azure App Service is a Platform as a Service (PaaS) offering that allows developers
to build, deploy, and scale web apps without managing the underlying infrastructure.
8. Which of the following describes the concept of 'Agility' in cloud computing?
A. The ability to increase computing power as demand increases.
B. The ability to rapidly develop, test, and launch software applications.
C. The ability of a system to remain functional after a failure.
D. The ability to pay only for what you use.
, Rationale: Cloud agility refers to the speed at which an organization can provision resources
to develop and deploy new applications, shortening the time to market.
9. What is a "Public Cloud"?
A. Cloud services offered over the internet to anyone who wants to purchase them.
B. Cloud services accessible only by a single organization.
C. A combination of public and private clouds.
D. Cloud services managed by a government agency.
Rationale: In a public cloud, hardware, software, and other supporting infrastructure are
owned and managed by the cloud provider and shared among multiple organizations.
10. Which Azure component can be used to group resources that share the same lifecycle,
permissions, and policies?
A. Resource Groups
B. Azure Subscriptions
C. Azure Regions
D. Management Groups
Rationale: Resource groups are containers that hold related resources for an Azure solution,
allowing for unified management and lifecycle operations.
11. Which service is used to store unstructured data in the cloud?
A. Azure Blob Storage
B. Azure SQL Database
C. Azure Files
D. Azure Queue Storage
Rationale: Azure Blob Storage is designed for massive amounts of unstructured data, such as
text or binary data (images, videos, logs).
12. You are designing a system that must be highly available. What is the minimum
number of virtual machines you should deploy in an Availability Set?
A. 1
B. 2
C. 3
D. 4
Rationale: To satisfy the 99.95% SLA provided by Azure for Availability Sets, you must deploy
at least two virtual machines in the set.
