AWS ACF Módulo 1 - Visão geral dos conceitos de nuvem

What is a hypervisor?

• Software to manage virtualized resources on a physical implementation.

• Software to log and monitor operations

• Hardware to connect networking and compute modules

• Hardware to provide to connect storage and compute modules

Which one represents Infrastructure as a Service (IaaS)?

• Infrastructure that allow developers to run their code.

• Services are provided without infrastructure or service maintenance concerns.

• You get control over underlying compute and storage resources

• Infrastructure complexity is automated and hidden via an API

Which one represents Platform as a Service (PaaS)?

• You get control over underlying compute and storage resources

• Services are provided without infrastructure or service maintenance concerns

• Infrastructure complexity is automated and hidden via an API or the push of a button.

• Infrastructure that allow developers to run their code.

Which represents fault tolerance?

• An application adjusting resource utilization according to demand.

• An application delivering data fast over large distances.

• An application recovering a component after a failure

• An application deployed across multiple regions

Which represents scalability?

• An application recovering a component after a failure.

• An application adjusting resource utilization according to demand.

• An application delivering data fast over large distances.

Which one IS NOT a value proposition provided by AWS?

• Multiregional presence

• Highly experienced teams of security engineers

• Metered, pay-per-use pricing

• Deep experience in the streaming space

Which of the following are advantages of having infrastructure hosted on the AWS Cloud? Choose 2 answers from the options give below.

• Having complete control over the physical infrastructure.

• Having the pay as you go model.

• No Upfront costs

• Having no need to worry about security

Which of the following statements about scalability is most accurate? Choose 2 answers from the options give below.

• A scalable system diverts traffic based on demand

• A scalable system diverts traffic to instances with the least load

• A scalable system diverts traffic across multiple regions

• A scalable system diverts traffic to instances with higher capacity

Your design team is planning to design an application that will be hosted on the AWS Cloud. One of their main non-functional requirements is given below:

“Reduce inter-dependencies so failures do not impact other components”.

Which of the following concepts does this requirement relate to?

• Integration

• Decoupling

• Aggregation

• Segregation
