Quiz 3 Cloud Model Functionality and Technical Differences

What is the primary focus of SaaS (Software as a Service)?

• Delivering infrastructure

• Providing software applications over the internet

• Managing networking hardware

• Delivering virtualisation tools

Answer explanation

The primary focus of SaaS is providing software applications over the internet, allowing users to access and use software without needing to install it locally. This distinguishes it from other models like IaaS or PaaS.

In IaaS (Infrastructure as a Service), what is typically provided to the user?

• Physical hardware

• Networking, storage, and virtualised computing resources

• Pre-installed software applications

• Custom-built cloud services

Answer explanation

In IaaS, users are provided with networking, storage, and virtualized computing resources, allowing them to manage and scale their infrastructure without needing physical hardware.

Which of the following is an example of PaaS (Platform as a Service)?

• Microsoft Azure App Services

• Google Docs

• Amazon EC2

• Dropbox

Answer explanation

Microsoft Azure App Services is a PaaS offering that provides a platform for building, deploying, and managing applications without worrying about the underlying infrastructure. The other options are not PaaS.

True or False: IaaS requires the user to manage operating systems and applications.

• True

• False

Answer explanation

True. IaaS (Infrastructure as a Service) provides virtualized computing resources, but users are responsible for managing the operating systems and applications running on those resources.

Which cloud model offers the highest level of control to the user?

• SaaS

• PaaS

• IaaS

• FaaS

Answer explanation

IaaS (Infrastructure as a Service) provides the highest level of control to users, allowing them to manage virtual machines, storage, and networks. In contrast, SaaS and PaaS offer less control, focusing on applications and platforms.

Which of the following is a characteristic of SaaS?

• Custom hardware management

• Subscription-based access

• Requires OS configuration

• Focuses on container orchestration

Answer explanation

SaaS (Software as a Service) is characterized by subscription-based access, allowing users to pay for software on a recurring basis without needing to manage hardware or configure operating systems.

What is the main difference between IaaS and PaaS?

• IaaS provides hardware resources, while PaaS includes development tools and frameworks

• PaaS is less scalable than IaaS

• PaaS requires manual storage setup

• IaaS offers more pre-installed software

Answer explanation

The main difference is that IaaS (Infrastructure as a Service) provides virtualized hardware resources, while PaaS (Platform as a Service) offers development tools and frameworks for building applications.

What is a typical use case for PaaS?

• Developing and deploying web applications

• Hosting static websites

• Email and document management

• Storing backup data

Answer explanation

PaaS (Platform as a Service) is primarily used for developing and deploying web applications, providing developers with the tools and services needed to build, test, and manage applications without worrying about the underlying infrastructure.

Fill in the blank: SaaS solutions are hosted on the provider’s ________.

Answer explanation

SaaS solutions are hosted on the provider’s infrastructure, which refers to the physical and virtual resources that support the delivery of software services over the internet.

True or False: PaaS eliminates the need to manage underlying hardware and operating systems.

• True

• False

Answer explanation

True. PaaS (Platform as a Service) abstracts the underlying hardware and operating systems, allowing developers to focus on building applications without managing infrastructure.
