Virtualization and Cloud Computing 220-1201 Practice Quiz

• A. A private cloud is a cloud environment dedicated to one organization, giving that organization greater control over access, security, configuration, and resource placement.
• B. In this scenario, a public cloud is a provider-owned cloud environment that delivers shared computing services to multiple customers over the internet.
• C. In this scenario, a hybrid cloud combines private cloud, public cloud, or on-premises resources so workloads and data can move or integrate across environments.
• D. In this scenario, a community cloud is shared by organizations with common requirements, such as regulatory, security, mission, or industry needs.

A private cloud is a cloud environment dedicated to one organization, giving that organization greater control over access, security, configuration, and resource placement. Private cloud is chosen when control and dedicated use matter more than broad public-provider sharing. This is the correct answer.

• A. In this scenario, infrastructure as a service provides virtualized computing infrastructure such as servers, storage, and networking while the customer manages operating systems and applications.
• B. A public cloud is a provider-owned cloud environment that delivers shared computing services to multiple customers over the internet.
• C. In this scenario, software as a service delivers a complete application through the provider, usually accessed through a browser or client app.
• D. In this scenario, platform as a service provides a managed application platform where developers can build, test, and deploy applications without managing the underlying servers.

A public cloud is a provider-owned cloud environment that delivers shared computing services to multiple customers over the internet. Public cloud is commonly selected for scalability, broad availability, and reduced need to own physical infrastructure. This is the correct answer.

• A. The most accurate interpretation is that platform as a service provides a managed application platform where developers can build, test, and deploy applications without managing the underlying servers.
• B. In this scenario, a private cloud is a cloud environment dedicated to one organization, giving that organization greater control over access, security, configuration, and resource placement.
• C. The most accurate interpretation is that shared resources means cloud infrastructure can pool compute, storage, and network capacity so multiple workloads or customers use provider-managed capacity efficiently.
• D. The most accurate interpretation is that metered utilization means cloud usage is measured so customers can be billed, monitored, or limited based on actual consumption.

A private cloud is a cloud environment dedicated to one organization, giving that organization greater control over access, security, configuration, and resource placement. Private cloud is chosen when control and dedicated use matter more than broad public-provider sharing. This is the correct answer.

• A. The most accurate interpretation is that rapid elasticity is the ability to quickly scale cloud resources up or down as demand changes.
• B. The most accurate interpretation is that high availability is the design goal of keeping services accessible by reducing single points of failure and using redundancy or failover.
• C. In this scenario, a public cloud is a provider-owned cloud environment that delivers shared computing services to multiple customers over the internet.
• D. The most accurate interpretation is that file synchronization keeps files consistent across devices or cloud storage locations by updating changes between them.

A public cloud is a provider-owned cloud environment that delivers shared computing services to multiple customers over the internet. Public cloud is commonly selected for scalability, broad availability, and reduced need to own physical infrastructure. This is the correct answer.

• A. The most accurate interpretation is that desktop virtualization separates the user desktop environment from the physical endpoint so the desktop can run centrally or in a cloud-hosted platform.
• B. The most accurate interpretation is that VDI on premises hosts virtual desktops inside the organization’s own data center or local infrastructure.
• C. The most accurate interpretation is that VDI in the cloud hosts virtual desktops through cloud infrastructure or a cloud desktop service.
• D. In this scenario, a hybrid cloud combines private cloud, public cloud, or on-premises resources so workloads and data can move or integrate across environments.

A hybrid cloud combines private cloud, public cloud, or on-premises resources so workloads and data can move or integrate across environments. Hybrid cloud is useful when an organization needs both local control and public-cloud flexibility. This is the correct answer.

• A. Operationally, file synchronization keeps files consistent across devices or cloud storage locations by updating changes between them.
• B. Operationally, desktop virtualization separates the user desktop environment from the physical endpoint so the desktop can run centrally or in a cloud-hosted platform.
• C. The most accurate interpretation is that a private cloud is a cloud environment dedicated to one organization, giving that organization greater control over access, security, configuration, and resource placement.
• D. Operationally, VDI on premises hosts virtual desktops inside the organization’s own data center or local infrastructure.
