Identify the correct description of a public cloud

Which of the following best describes a public cloud deployment model?

A A cloud environment owned and operated by a single organization for its exclusive use.

B A cloud environment combining on-premises infrastructure with public cloud services.

C A cloud environment shared by multiple organizations, managed by a third-party provider.

D A cloud environment that is physically located only on the user's premises.

💡 Hint

Think about who manages the cloud and who can access it.

A public cloud is managed by a third-party provider and shared among multiple organizations, offering scalable resources over the internet.

Choose the correct Azure service for a private cloud setup

Which Azure service is primarily used to create a private cloud environment within an organization's own data center?

A Azure Virtual Machines

B Azure Stack Hub

C Azure Blob Storage

D Azure App Service

💡 Hint

Look for the service that extends Azure to on-premises.

Azure Stack Hub allows organizations to run Azure services in their own data centers, creating a private cloud environment.

Behavior of hybrid cloud during network outage

In a hybrid cloud setup using Azure Arc, what happens to workloads running on on-premises servers if the connection to the Azure public cloud is lost?

A Workloads continue running locally without interruption.

B All workloads immediately stop until the connection is restored.

C Workloads automatically migrate to Azure public cloud.

D Azure Arc disables all on-premises resources remotely.

💡 Hint

Consider how hybrid cloud supports local operations.

Hybrid cloud allows workloads to run locally on-premises even if the connection to the public cloud is lost, ensuring continuity.

❓ security

Security advantage of private cloud over public cloud

Which security advantage is unique to private cloud deployments compared to public clouds?

A Automatic software patching by the cloud provider.

B Unlimited scalability without hardware constraints.

C Shared security responsibility with multiple tenants.

D Exclusive physical access control to hardware by the organization.

💡 Hint

Think about physical control over infrastructure.

Private clouds allow organizations exclusive physical access to their hardware, enhancing security compared to shared public cloud environments.

Best practice for data residency in hybrid cloud

An organization must comply with strict data residency laws requiring sensitive data to remain within their country. Which hybrid cloud deployment practice best meets this requirement using Azure?

A Use Azure Stack Hub on-premises for sensitive data and Azure public cloud for less sensitive workloads.

B Store all sensitive data in Azure public cloud regions outside the country and use encryption.

C Migrate all workloads to Azure public cloud and rely on Microsoft's compliance certifications.

D Keep all data on local servers without any cloud integration.

💡 Hint

Consider combining on-premises and cloud to meet legal requirements.

Using Azure Stack Hub on-premises ensures sensitive data stays within the country, while less sensitive workloads can run in the public cloud, balancing compliance and cloud benefits.
