Cloud Deployment Models

What cloud deployment model is described as "services and resources are available to the public over the internet, owned and operated by a third-party provider"?

• Private Cloud

• Community Cloud

• Public Cloud

• Hybrid Cloud

Answer explanation

A public cloud is accessible to anyone over the internet and is managed by third-party providers like AWS, Google Cloud, or Microsoft Azure. Organizations don't have to maintain the infrastructure, but it may lack control and security customization.

Which cloud deployment model is hosted on-premises or at a dedicated location, exclusively for a single organization?

• Public Cloud

• Private Cloud

• Hybrid Cloud

• Multi-Cloud

Answer explanation

A private cloud is used solely by one organization. It offers full control over infrastructure, security, and data but is more expensive to maintain since it's not shared with others.

A deployment model that combines private and public cloud features to allow data and applications to be shared between them is called:

• • Hybrid Cloud

• Community Cloud

• Public Cloud

• Private Cloud

Answer explanation

A hybrid cloud combines private and public cloud capabilities, enabling organizations to keep sensitive data private while leveraging the scalability of public clouds for less critical workloads.

Which cloud model is shared by several organizations and supports a specific community with shared concerns, such as security, compliance, or policy requirements?

• Public Cloud

• Hybrid Cloud

• Community Cloud

• Private Cloud

Answer explanation

A community cloud is designed for a group of organizations with common goals or compliance needs, such as government agencies or healthcare providers. Resources are shared, but access is restricted to the community members.

Which cloud deployment model involves using multiple cloud services from different providers for better redundancy and performance?

• Public Cloud

• Private Cloud

• Multi-Cloud

• Hybrid Cloud

Answer explanation

Multi-cloud refers to using services from multiple cloud providers (e.g., AWS, Azure, and Google Cloud) simultaneously. This improves redundancy, avoids vendor lock-in, and optimizes performance for different workloads.

True or False: A Private Cloud is always hosted on-premises.

• True

• False

Answer explanation

A private cloud can be hosted on-premises or by a third-party provider. The defining feature is that it is dedicated to one organization, regardless of its physical location.

What is a primary advantage of the Hybrid Cloud model?

• High cost savings compared to private cloud

• Complete isolation of resources

• Flexibility to move workloads between public and private clouds

• • It is managed by the public cloud provider

Answer explanation

A hybrid cloud provides the flexibility to move workloads between public and private environments. This allows organizations to maintain control over sensitive data while benefiting from public cloud scalability and cost-effectiveness for less critical workloads.

Which deployment model is best suited for highly regulated industries, such as healthcare, where organizations need to collaborate but maintain strict compliance?

• Public Cloud

• Community Cloud

• Hybrid Cloud

• Multi-Cloud

Answer explanation

A community cloud is tailored to the specific needs of organizations in the same industry or sector with strict compliance requirements, like HIPAA for healthcare. Resources are shared but remain exclusive to the community.

What is a key disadvantage of the Public Cloud model

• Limited scalability

• High cost

• Less control over data and security

• Lack of collaboration features

Answer explanation

Public clouds are cost-effective and highly scalable, but the trade-off is limited control over data and security configurations since the infrastructure is managed by the provider.

If an organization uses AWS for some applications and Azure for others, this is an example of:

• Public Cloud

• Community Cloud

• Multi-Cloud

• Private Cloud

Answer explanation

Using multiple cloud providers (e.g., AWS for machine learning and Azure for databases) is an example of a multi-cloud strategy. It improves flexibility, avoids reliance on a single provider, and can optimize costs or performance for specific use cases.
