Cloud Computing Concepts Quiz

What does "Rapid Elasticity" mean in cloud computing?

• Fixed resource allocation

• Scaling resources dynamically based on demand

• Rapid data transfer

• Fixed pricing for resources

Answer explanation

"Rapid Elasticity" in cloud computing refers to the ability to scale resources dynamically based on demand, allowing for efficient resource management and cost-effectiveness. This is why the correct answer is scaling resources dynamically based on demand.

What is "Ubiquitous Access"?

• Restricted access to certain devices

• Access to resources anytime, anywhere

• Limited access within office networks

• Sharing resources only with local users

Answer explanation

Ubiquitous Access refers to the ability to access resources anytime, anywhere, enabling users to connect from various locations and devices, unlike restricted or limited access options.

What does "Rapid Deployment" allow in cloud computing?

• Slower provisioning of resources

• Immediate availability of resources and services

• Manual configuration of services

• Delayed scaling of systems

Answer explanation

"Rapid Deployment" in cloud computing enables immediate availability of resources and services, allowing users to quickly access and utilize cloud capabilities without delays, unlike slower provisioning or manual configurations.

What does "On-demand Self-Service" mean?

• Resources require approval before use

• Users can provision resources automatically without intervention

• Services are allocated manually by IT staff

• Resources are shared between users by default

Answer explanation

"On-demand Self-Service" means users can provision resources automatically without needing approval or intervention from IT staff, allowing for greater efficiency and flexibility in resource management.

What is meant by "Resource Pooling"?

• Dedicated resources for each user

• Shared resources among multiple users

• Isolated resources per department

• Fixed allocation of resources

Answer explanation

Resource pooling refers to the practice of sharing resources among multiple users, allowing for more efficient use and flexibility. This contrasts with dedicated or isolated resources, which are not shared.

Which pricing model describes "Pay-as-you-grow"?

• Fixed yearly billing

• Pay only for the resources you use

• Free for small businesses

• Pay upfront for all potential resources

Answer explanation

The "Pay-as-you-grow" model means you only pay for the resources you actually use, making "Pay only for the resources you use" the correct choice. This model allows for flexibility and cost efficiency as needs increase.

What is "Multi-tenancy"?

• Multiple users share the same application instance securely

• Each user has a dedicated server

• Resources cannot be shared

• A single tenant uses the entire cloud

Answer explanation

Multi-tenancy allows multiple users to securely share the same application instance, optimizing resource use and reducing costs. This distinguishes it from dedicated servers or single-tenant models.

What is "Automation" in cloud computing?

• Manual configuration of systems

• Automatic execution of processes without manual intervention

• Reduced system functionality

• Human-based resource allocation

Answer explanation

Automation in cloud computing refers to the automatic execution of processes without manual intervention, streamlining operations and improving efficiency. This distinguishes it from manual configurations and human-based resource allocation.

What does "Chargeback" mean in cloud computing?

• Billing customers for their allocated resources

• A refund for unused resources

• A penalty for exceeding usage

• Free resource scaling

Answer explanation

In cloud computing, a "Chargeback" refers to billing customers for their allocated resources. This means customers are charged based on the resources they use, making it essential for cost management.

What is "Cloud Bursting"?

• Automatically moving workloads to a public cloud during peak demand

• Cloud systems crashing under heavy load

• Expanding storage permanently

• Sharing resources between private clouds

Answer explanation

Cloud Bursting refers to the practice of automatically moving workloads to a public cloud during peak demand, allowing businesses to handle increased traffic without over-provisioning their private cloud resources.
