Describe Cloud Concepts

Question 1

Por que a computação em nuvem normalmente é mais econômica?

Answer 1

Reduzir os custos operacionais.
Executar a infraestrutura com mais eficiência.
Escale as operações de acordo com as necessidades de negócios.

Question 2

O que significa computação em nuvem?

Answer 2

Entrega de serviços de computação pela Internet.

A computação em nuvem é a entrega de serviços de computação pela Internet, que também é conhecida como nuvem

Question 3

O que é Nuvem pública?

Answer 3

Services are offered over the public internet and available to anyone who wants to purchase them. Cloud resources, such as servers and storage, are owned and operated by a third-party cloud service provider, and delivered over the internet.

No capital expenditures to scale up.
Applications can be quickly provisioned and deprovisioned.
Organizations pay only for what they use.

Question 4

O que é Nuvem privada?

Answer 4

A private cloud consists of computing resources used exclusively by users from one business or organization. A private cloud can be physically located at your organization’s on-site (on-premises) datacenter, or it can be hosted by a third-party service provider.

Hardware must be purchased for start-up and maintenance.
Organizations have complete control over resources and security.
Organizations are responsible for hardware maintenance and updates.

Question 5

O que é Nuvem hibrida?

Answer 5

A hybrid cloud is a computing environment that combines a public cloud and a private cloud by allowing data and applications to be shared between them.

Provides the most flexibility.
Organizations determine where to run their applications.
Organizations control security, compliance, or legal requirements.

Question 6

oq é Alta disponibilidade?

Answer 6

Depending on the service-level agreement (SLA) that you choose, your cloud-based apps can provide a continuous user experience with no apparent downtime, even when things go wrong.

Question 7

oq é Escalabilidade?

Answer 7

Apps in the cloud can scale vertically and horizontally:

Scale vertically to increase compute capacity by adding RAM or CPUs to a virtual machine.
Scaling horizontally increases compute capacity by adding instances of resources, such as adding VMs to the configuration.

Question 8

oq é Elasticidade?

Answer 8

You can configure cloud-based apps to take advantage of autoscaling, so your apps always have the resources they need.

Question 9

oq é Agilidade?

Answer 9

Deploy and configure cloud-based resources quickly as your app requirements change.

Question 10

oq é Distribuição geográfica?

Answer 10

You can deploy apps and data to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region.

Question 11

oq é Recuperação de desastre?

Answer 11

By taking advantage of cloud-based backup services, data replication, and geo-distribution, you can deploy your apps with the confidence that comes from knowing that your data is safe in the event of disaster.

Question 12

oq é CapEx (despesas de capital)?

Answer 12

is the up-front spending of money on physical infrastructure, and then deducting that up-front expense over time. The up-front cost from CapEx has a value that reduces over time.

Question 13

oq é OpEx (despesas operacionais)?

Answer 13

is spending money on services or products now, and being billed for them now. You can deduct this expense in the same year you spend it. There is no up-front cost, as you pay for a service or product as you use it.

Question 14

describe the consumption-based model

Answer 14

A consumption-based model has many benefits, including:

No upfront costs.
No need to purchase and manage costly infrastructure that users might not use to its fullest.
The ability to pay for additional resources when they are needed.
The ability to stop paying for resources that are no longer needed.

Question 15

oq é o modelo IaaS?

Answer 15

This cloud service model is the closest to managing physical servers; a cloud provider will keep the hardware up-to-date, but operating system maintenance and network configuration is up to you as the cloud tenant. For example, Azure virtual machines are fully operational virtual compute devices running in Microsoft datacenters. An advantage of this cloud service model is rapid deployment of new compute devices. Setting up a new virtual machine is considerably faster than procuring, installing, and configuring a physical server.

Question 16

oq é o modelo PasS?

Answer 16

This cloud service model is a managed hosting environment. The cloud provider manages the virtual machines and networking resources, and the cloud tenant deploys their applications into the managed hosting environment. For example, Azure App Services provides a managed hosting environment where developers can upload their web applications, without having to worry about the physical hardware and software requirements.

Question 17

oq é o modelo SaaS?

Answer 17

In this cloud service model, the cloud provider manages all aspects of the application environment, such as virtual machines, networking resources, data storage, and applications. The cloud tenant only needs to provide their data to the application managed by the cloud provider. For example, Microsoft Office 365 provides a fully working version of Microsoft Office that runs in the cloud. All you need to do is create your content, and Office 365 takes care of everything else.

Question 18

What is serverless computing?

Answer 18

Like PaaS, serverless computing enables developers to build applications faster by eliminating the need for them to manage infrastructure. With serverless applications, the cloud service provider automatically provisions, scales, and manages the infrastructure required to run the code. Serverless architectures are highly scalable and event-driven, only using resources when a specific function or trigger occurs.

It’s important to note that servers are still running the code. The “serverless” name comes from the fact that the tasks associated with infrastructure provisioning and management are invisible to the developer

Question 19

Question:

Which of the following choices isn’t a cloud computing category?

Networking-as-a-Service (NaaS)

Platform-as-a-Service (PaaS)

Infrastructure-as-a-Service (IaaS)

Software-as-a-Service (SaaS)

Answer 19

Networking-as-a-Service (NaaS)

That’s correct. NaaS isn’t a cloud computing category.

Question 20

Question:

Which of the following statements is true?

With Operating Expenses (OpEx), you are responsible for purchasing and maintaining your computing resources.

With Operating Expenses (OpEx), you are only responsible for the computing resources that you use.

With Capital Expenses (CapEx), you are only responsible for the computing resources that you use.

Answer 20

With Operating Expenses (OpEx), you are only responsible for the computing resources that you use.

That’s correct. With Operating Expenses (OpEx), you are only responsible for the computing resources that you use.

Question 21

Question:

Which of the following options isn’t a type of cloud computing?

Distributed cloud

Hybrid cloud

Private cloud

Public cloud

Answer 21

Distributed cloud

That’s correct. A distributed cloud isn’t a valid type of cloud computing.

Question 22

Question:

Which of the following choices isn’t a benefit of using cloud services?

Scalability

Disaster recovery

High availability

Geographic isolation

Answer 22

Geographic isolation

That’s correct. You can choose to create resources in a single region; however, one of the primary advantages to cloud computing is geographic distribution.
