Question 551
What is the first stage in the Microsoft Cloud Adoption Framework for Azure?
A. Adopt the cloud.
B. Make a plan.
C. Ready your organization.
*D. Define your strategy.
Explanation
Question 552
A company can extend an internal network by adding its own physical servers to the public cloud.
A. Yes
*B. No
Explanation
You cannot add physical servers to the public cloud. You can only deploy virtual servers in the public cloud. You can extend a private cloud by deploying virtual servers in a public cloud. This would create a hybrid cloud.
Question 553
A private cloud must be disconnected from the internet.
A. Yes
*B. No
Explanation
A private cloud exists in cyberspace and is accessed via the internet.
Question 554
Part of a hybrid cloud is the public cloud.
*A. Yes
B. No
Question 555
You must have physical servers to use cloud computing.
A. Yes
*B. No
Explanation
Virtual Machines works.
Question 556
You must have internet connectivity to use cloud computing.
*A. Yes
B. No
Explanation
Simply put, cloud computing is the delivery of computing services “including servers, storage, databases, networking, software, analytics, and intelligence” over the Internet (the cloud) to offer faster innovation, flexible resources, and economies of scale.
Question 557
The costs to increase cloud computing capacity are less than the costs to increase the computing capacity of an on-premises datacenter.
*A. Yes
B. No
Question 558
Match the cloud computing benefits to the correct descriptions.
To answer, drag the appropriate benefit from the column on the left to its description on the right. Each benefit may be used once, more than once, or not at all.
NOTE: Each correct match is worth one point.
Benefits:
- Agility
- Geo-distribution
- Scalability
Answer Area:
- Resources can be provisioned dynamically to meet changing demands.
- Applications and data can be deployed to multiple regions.
- Applications can be developed, tested, and launched rapidly.
Answer:
- Scalability: Resources can be provisioned dynamically to meet changing demands.
- Geo-distribution: Applications and data can be deployed to multiple regions.
- Agility: Applications can be developed, tested, and launched rapidly.
Question 559
Azure Site Recovery provides _________________ for virtual machines.
A. fault tolerance
*B. disaster recovery
C. elasticity
D. high availability
Explanation
You set up disaster recovery for Azure VMs using Azure Site Recovery.
Question 560
You plan to use Azure to host two apps named App1 and App2. The apps must meet the following requirements:
- You must be able to modify the code of App1.
- Administrative effort to manage the operating system of App1 must be minimized.
- App2 must run interactively with the operating system of the server.
Which type of cloud service should you use for each app? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
App1:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
App2:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Answer:
- App1: Platform as a Service (PaaS)
- App2: Software as a Service (SaaS)
Explanation
Box 1: Azure Platform as a service (PaaS)
Organizations typically use PaaS for these scenarios:
Development framework. PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. Similar to the way you create an Excel macro, PaaS lets developers create applications using built-in software components. Cloud features such as scalability, high-availability, and multi-tenant capability are included, reducing the amount of coding that developers must do.
Box 2:
Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet.
Common examples are email, calendaring, and office tools (such as Microsoft Office 365).
SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization, and your users connect to it over the Internet, usually with a web browser. All of the underlying infrastructure, middleware, app software, and app data are located in the service provider’s data center. The service provider manages the hardware and software, and with the appropriate service agreement, will ensure the availability and the security of the app and your data as well. SaaS allows your organization to get quickly up and running with an app at minimal upfront cost.
