At what layer in the OSI model is the human - CPU layer? correct answers Application
At what layer in the OSI model makes data usable? correct answers Presentation
At what layer in the OSI model maintains a connection? correct answers Session
At what layer in the OSI model does the transmiting of data across networks occur? correct
answers Transport
At what layer in the OSI model do IP addresses use? correct answers Network
At what layer in the OSI model contains Wi-Fi and ethernet correct answers Data Link
At what layer in the OSI model houses the wires and raw bits? correct answers Physical
As data moves from the the direct connection between devices towards the data the user cares
about, it is _____ with additional information. correct answers decapsulation, decapsulated
What is the cloud? correct answers Leasing of space that is not your hardware
How is the cloud green? correct answers The cloud can save an organization money because they
don't need to run and maintain physical servers and are better for the environment because you
only pay for the exact energy you use with less excess energy wasted.
Is the cloud a safer computing environment than an in-house network? correct answers Not
necessarily because the cloud provider is a bigger target to hit and you entrust your data in a
single organization.
What is chaos monkey? correct answers Chaos money was invented by Netflix to shut down
random systems but because of redundancy, there was not change in user experience.
What does elasticity mean? correct answers The ability to scale out and scale back as needed
based on demand
, What is IaaS (Infrastructure as a Service)? correct answers Cloud model where the cloud
provider provides the hardware and virtualization.
Least convenience and most control.
What is PaaS (Platform as a Service)? correct answers Cloud model where the cloud provider
provides the hardware, virtualization, and operating system.
Some convenience and some control.
What is SaaS (Software As A Service)? correct answers Cloud model where the cloud provider
provides the hardware, virtualization, operating system, middleware, and applications. Cloud
provider controls everything.
Most convenience and least control.
Out of IaaS, SaaS, and PaaS, rank them on a scale on most to least control for the user correct
answers Most control: IaaS -> PaaS - SaaS
What does the s stand for in https correct answers secure
What layer of the OSI model is http or https? correct answers Layer seven or the application
layer because it is what the user interacts with
