Quiz 20A: Summarize Cloud Concepts

What is a primary characteristic of cloud computing from the consumer's perspective?

• Detailed control over infrastructure management

• Direct responsibility for infrastructure procurement

• On-demand access to resources over a network

• Ownership of underlying infrastructure

How does scalability in cloud computing affect costs?

• Costs decrease proportionally with increased demand

• Costs increase linearly with increased demand

• Costs remain constant regardless of demand fluctuations

• Costs are inversely related to demand

Which method of scalability involves adding resources to each node?

• Vertical scaling

• Horizontal scaling

• Elastic scaling

• Static scaling

What is the primary advantage of elasticity in cloud computing?

• Reduced infrastructure costs

• Increased control over resources

• Ability to handle demand fluctuations

• Enhanced security measures

How do cloud providers achieve automatic provisioning and deprovisioning of resources?

• Through resource pooling and virtualization

• By implementing strict access control policies

• Through manual intervention by data center staff

• By limiting user access to specific services

Which cloud deployment model offers the highest level of security and performance but is also the most expensive?

• Public cloud

• Hosted private cloud

• Private cloud

• Community cloud

In a hybrid cloud deployment, what determines which functions are provided via a public cloud and which are kept on-premises?

• Data volume

• Network latency

• Security requirements

• Geographic location

Which cloud service model provides resources such as servers and storage area networks (SAN) on a rental basis?

• Software as a Service (SaaS)

• Platform as a Service (PaaS)

• Desktop as a Service (DaaS)

• Infrastructure as a Service (IaaS)

What distinguishes Platform as a Service (PaaS) from Software as a Service (SaaS)?

• PaaS provides complete software applications, while SaaS provides only the platform.

• PaaS offers resources such as servers and storage, while SaaS provides ready-to-use software applications.

• PaaS requires users to develop and configure their own applications, while SaaS offers pre-built software applications.

• PaaS focuses on virtual desktop infrastructure, while SaaS focuses on platform provisioning.

What is the primary purpose of Desktop as a Service (DaaS)?

• Provisioning virtual desktop infrastructure (VDI) as a cloud service

• Offering resources such as servers and storage area networks (SAN) on a rental basis

• Providing ready-to-use software applications over the Internet

• Hosting multi-tier web application/database platforms
