Question 1

What is 'Infrastructure as a Service' (IaaS) in a cloud service provider context?

Accepted Answer

Providing virtualized computing, storage, and networking resources on demand

Answer

IaaS delivers fundamental computing infrastructure — virtual machines, storage, and networking — on a pay-per-use basis, allowing customers to build their own IT environments.

Question 2

In cloud services, what is the 'shared responsibility model'?

Accepted Answer

A framework defining which security controls are the provider's responsibility versus the customer's

Answer

The shared responsibility model delineates security duties: the provider secures the cloud infrastructure itself, while the customer is responsible for securing data, access, and applications within the cloud.

Question 3

What is 'auto-scaling' in a cloud service provider environment?

Accepted Answer

Dynamically adding or removing compute resources in response to demand changes

Answer

Auto-scaling automatically increases or decreases the number of compute instances based on real-time demand metrics, ensuring performance without over-provisioning.

Question 4

What does 'PaaS' (Platform as a Service) provide to application developers?

Accepted Answer

A managed platform with runtimes, databases, and middleware so developers focus only on writing code

Answer

PaaS provides a complete managed environment including operating systems, runtime, middleware, and databases, freeing developers from infrastructure management.

Question 5

What is a 'hypervisor' in a virtualization context?

Accepted Answer

Software that creates and manages virtual machines by abstracting physical hardware resources

Answer

A hypervisor is software that sits between physical hardware and virtual machines, abstracting hardware resources and enabling multiple VMs to run on a single physical host.
