CompTIA A+ Certification Core 1 (220-1101) - Cloud Computing

The video tutorial introduces cloud computing, explaining its concept and benefits such as rapid elasticity, on-demand capabilities, and resource pooling. It covers different service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), highlighting their advantages and applications. The tutorial emphasizes the cost efficiency and scalability of cloud services, using examples like Amazon Web Services and Google Docs to illustrate these concepts.

What is a key characteristic of cloud computing?

• Physical proximity to the server

• Remote access to virtual machines

• Limited scalability

• Ownership of hardware

How does cloud computing provide rapid elasticity?

• By reducing server costs

• By allowing quick duplication of virtual machines

• By increasing physical server space

• By limiting user access

What is an example of on-demand resource allocation in cloud computing?

• Purchasing new hardware for peak times

• Cloning virtual machines during high traffic events

• Reducing server capacity permanently

• Manually adjusting server settings

What is resource pooling in the context of cloud computing?

• Combining virtual machines for efficiency

• Limiting access to certain users

• Sharing physical hardware among users

• Pooling financial resources for server costs

Which company is known for providing infrastructure as a service?

• Google

• Apple

• Microsoft

• Amazon Web Services

What is a benefit of Platform as a Service for developers?

• Direct control over hardware

• Simplified code deployment

• Manual server management

• Increased physical storage

Which of the following is an example of Software as a Service?

• Using Google Docs online

• Installing software on a local machine

• Purchasing a software license

• Developing a custom application
