Question 156

Which cloud computing model includes on-premises and cloud-based resources?

A. hybrid
B. public
C. private
Show Answer
Correct Answer: A
Explanation:
A hybrid cloud model combines on‑premises infrastructure with cloud‑based resources (typically public cloud services), enabling workloads and data to move between them. Public cloud is fully off‑premises, and private cloud alone does not inherently include public cloud resources.

Correct Answer: Platform as a Service (PaaS)
Explanation:
The database is hosted in the cloud and software updates are managed by Azure, meaning the provider manages the platform (OS, database engine, patching), which is characteristic of PaaS rather than IaaS or SaaS.

Question 159

You plan to deploy a service to Azure virtual machines. You need to ensure that the service will be available if a datacenter fails. What should you use as part of the virtual machine deployment?

A. availability sets
B. proximity placement groups
C. host groups
D. availability zones
Show Answer
Correct Answer: D
Explanation:
To remain available if a datacenter fails, VMs must be deployed across physically separate datacenters. Azure availability zones provide isolated physical locations within a region, each with independent power, cooling, and networking. Availability sets only protect against failures within a single datacenter, while proximity placement groups and host groups do not provide datacenter-level redundancy.

Correct Answer: The virtual machines can be moved to the new subscription.
Explanation:
Azure supports moving virtual machines and their dependent resources between subscriptions, provided all required associated resources are moved together and the subscriptions are within the same Azure AD tenant.

Question 161

DRAG DROP - Match the Azure governance feature to the correct description. Instructions: To answer, drag the appropriate feature from the column on the left to its description on the right. Each feature may be used once, more than once, or not at all. NOTE: Each correct match is worth one point. Select and Place:

Correct Answer: Restrict which virtual machine types can be created in a subscription: Azure Policy Identify Azure resources that are associated with specific cost centers: Azure tags Deploy a complete Azure application environment including resources configuration and role assignments: Azure Blueprints
Explanation:
Azure Policy enforces rules and restrictions on resources. Azure tags provide metadata for classification such as cost centers. Azure Blueprints package policies, role assignments, and resource templates to deploy complete environments.

Show Answer
Correct Answer: Microsoft Defender for Cloud
Explanation:
Just-in-time (JIT) VM access is a security feature provided by Microsoft Defender for Cloud to lock down inbound VM ports and open them only when needed.

Question 163

DRAG DROP - Match the Azure services to the correct descriptions. Instructions: To answer, drag the appropriate Azure service from the column on the left to its description on the right. Each service may be used once, more than once, or not at all. NOTE: Each correct match is worth one point. Select and Place:

Correct Answer: Provide operating system virtualization: Azure virtual machines Provide portable environment for virtualized applications: Azure Container Instances Used to build, deploy, and scale web apps: Azure App Service Provide a platform for serverless code: Azure Functions
Explanation:
Azure Virtual Machines virtualize hardware and run full operating systems. Azure Container Instances provide OS-level (container) virtualization for portable applications. Azure App Service is a managed PaaS for building and scaling web apps. Azure Functions is a serverless compute service for event-driven code.

Question 164

HOTSPOT - For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:

Illustration for AZ-900 question 164
Show Answer
Correct Answer: No No Yes
Explanation:
Cloud computing does not require you to own physical servers. Cloud services are delivered over the internet by definition. Scaling capacity in the cloud is generally cheaper than expanding an on‑premises datacenter.

Question 165

Which term represents the ability to increase the computing capacity of a virtual machine by adding memory or CPUs?

A. agility
B. vertical scaling
C. horizontal scaling
D. elasticity
Show Answer
Correct Answer: B
Explanation:
The question asks about increasing the computing capacity of a single virtual machine by adding memory or CPUs. That is vertical scaling (scaling up), which enhances resources within one VM. Horizontal scaling adds more VMs, elasticity refers to automatic scaling behavior, and agility is a broader organizational trait.
