Q1

Which of the following six advantages enables small start-up companies to immediately start consuming IT services from public cloud vendors such as AWS?

1. Trade capital expense for variable expense
2. Go global in minutes
3. Stop guessing capacity
4. Increase speed and agility

A: keywords are "small start-up" and and "immediately start consuming", so should be 3

Result: 4 [ ]

Q2

Which feature of cloud computing enables customers to deploy their resources in a matter of minutes using a self-service model?

1. Access to cloud provider APIs
2. Access to cloud provider engineers to rack and stack servers
3. Scalability features
4. Multiple server options

A: keywords are "deploy resources" and "self-service", so should be 1

Result: 1 [x]

Q3

What is a hypervisor?

1. Software that enables you to create and managed virtualized resources running on physical hardware, such as VMs
2. Software used to monitor the health of your Windows servers
3. Software used to create HA websites
4. Hardware that enables you to increase the performance of your physical servers

A: Hypervisor is used to carve resource out of hardware, to create resoure for VMs. So should be 1

Result: 1 [x]

Q4

Which of the following are the primary benefits of server virtualization? (Select two answers.)

1. Efficient use of physical hardware resources
2. Ability to provision virtual servers in a matter of minutes
3. Enhanced encryption services
4. Ability to meet compliance requirements

A: 1 & 2

Result: 1 & 2 [x]

Q5

Which of the following is a prime example of IaaS?

1. A service that gives you access to configure underlying virtual compute, storage, and network resources to host your application
2. A service that abstracts the underlying infrastructure, allowing you to focus on your application code deployment process
3. A service that hosts and delivers a complete application via a public network, with no access to any underlying infrastructure
4. A service that allows you to consume hardware resources for a short lease period and pay on a metered basis

A: IaaS provides hardware resource to create VM, but user still need to provision OS, environment, app, etc. So should be 1

Result: 1 [x]

Q6

Which of the following is a prime example of PaaS?

2. A service that gives you access to configure underlying virtual compute, storage, and network resources to host your application
3. A service that abstracts the underlying infrastructure, allowing you to focus on your application code deployment process
4. A service that allows you to build infrastructure using code for repeat deployments in different environments

A: PaaS provide provisioned VM, environment. User only need to add app source code to run service. So, it's 3

Result: 3 [x]

Q7

Which of the following is a prime example of SaaS?

1. A service that gives you access to configure underlying virtual compute, storage, and network resources to host your application
2. A service that abstracts the underlying infrastructure, allowing you to focus on your application code deployment process
3. A service that hosts and delivers a complete application via a public network, with no access to any underlying infrastructure
4. A service that allows developers to adopt DevOps strategies for their software development life cycle

A: SaaS provide entire provisioned service, so should be 3

Result: 3 [x]
