You can run your infrastructure more efficiently. Correct That's partially correct. One feature of Cloud services is that you can run your infrastructure more efficiently, and scale as your business needs change. C. You can scale as your business needs to change. That's partially correct. One feature of Cloud services is that you can scale as your business needs change.

You have been given the task to determine what solutions or services best suit your business needs. You need to provision end-to-end solutions quickly and reliably, hosted in your own Azure environment. ​ ​Which Azure solution would best suit your business goal? A. Azure Portal B. Azure Marketplace C. Azure Virtual Machines

B. Azure Marketplace In the Azure Marketplace you can find, try, buy, and deploy the software and services you need to build new solutions and manage your cloud infrastructure. You can provision end-to-end solutions quickly and reliably, hosted in your own Azure environment.

Azure provides four main types of storage services. One of these services Azure Blob storage provides for which of the following. A. File shares that you can access and manage like a file server. B. A data store for queuing and reliably delivering messages between applications. C. Storage service for very large objects such as video files or bitmaps. D. A NoSQL store that hosts unstructured data independent of any schema

C. Storage service for very large objects such as video files or bitmaps.

A cloud environment has several advantages over a physical environment and these benefits become available to companies once they have migrated to the cloud. One of these benefits is referred to as agility. What does agility provide? A. You can deploy your applications with the confidence that comes from knowing that your data is safe in the event of a disaster. B. Applications and data can be deployed to regional datacenters around the globe. C. Your cloud-based applications can provide continuous user experience with no apparent downtime even when things go wrong. D. Cloud-based resources can be deployed and configured quickly as your requirements change. With Agility, cloud-based resources can be deployed and configured quickly as your application requirements change.

D. Cloud-based resources can be deployed and configured quickly as your requirements change. With Agility, cloud-based resources can be deployed and configured quickly as your application requirements change.

In cloud computing, there are two different types of expenses that should be considered, capital expenditure (CapEx) and operational expenditure (OpEx). Which of these provides for the upfront spending of money on physical infrastructure, and then deducting that upfront expense overtime? A. Operational expenditure (OpEx) B. Capital expenditure (CapEx)

B. Capital expenditure (CapEx) Capital expenditure (CapEx) is the upfront spending of money on physical infrastructure and then deducting that upfront expense over time. The upfront cost from CapEx has a value that is reduced over time.

Cloud service models define the different levels of shared responsibility that a cloud provider and cloud tenant are responsible for. In which model does the cloud provider keep the hardware up to date but operating system maintenance and network configuration are left to the cloud tenant? A. SaaS B. IaaS C. PaaS

B. IaaS

Cloud computing is the delivery of computing services using a pay-as-you-go pricing model. Which of the following statements are true of the pay-as-you-go pricing model? Select all options that apply. A. You can immediately stop paying for resources that are no longer needed. B. You must pay a fixed fee in advance for all Cloud services. C. You rent physical hardware such as compute power and storage and maintain them within your own datacenter. D. You rent compute power and storage from someone else's datacenter.

A. You can immediately stop paying for resources that are no longer needed. You can treat cloud resources like you would resources in your own datacenter. When you are finished using them, you give them back. You are only billed for what you use. D. You rent compute power and storage from someone else's datacenter. Instead of maintaining CPUs and storage in your datacenter, you rent them for the time that you need them. The cloud provider takes care of maintaining the underlying infrastructure for you.

One of the advantages of cloud computing is scalability. Applications can be scaled vertically and horizontally. Do you think that the following statement is true or false? Horizontal scalability is when computing capacity can be increased by adding additional RAM or CPUs to a virtual machine. A. True B. False

B. False With vertical scaling, computing capacity can be increased by adding additional RAM or CPUs to a virtual machine. With horizontal scaling, computing capacity can be increased by adding instances of a resource. You can scale vertically by adding additional virtual machines to your configuration.

B. False The Azure Marketplace is a service on Azure that helps connect end-users with Microsoft partners, independent software vendors (ISVs), and start-ups that are offering solutions and services which are optimized to run on Azure. Azure Marketplace allows customers to find, try, purchase, and provision applications and services from hundreds of leading service providers, all certified to run on Azure.

Cloud Computing provides several benefits over a physical environment. Which of the following are benefits of cloud computing? Select all options that apply. A. Full control B. High availability C. Agility D. Elasticity

High availability Depending on the service-level agreement (SLA) that you choose, your cloud-based applications can provide a continuous user experience with no apparent downtime even when things go wrong. C. Agility Cloud-based resources can be deployed and configured quickly as your application requirements change. D. Elasticity Cloud-based applications can be configured to take advantage of autoscaling, so your applications will always have the resources they need.
