Explanation:
Box 1: No
A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides
an environment for you to host your web applications. Behind the scenes, the web apps are hosted on
virtual machines running IIS. However, you have no direct access to the virtual machine, the operating
system or IIS.
Box 2: Yes
A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically.
This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running
IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.
Box 3: Yes
PaaS provides a framework that developers can build upon to develop or customize cloud-based
applications. PaaS development tools can cut the time it takes to code new apps with pre-coded application
components built into the platform, such as workflow, directory services, security features, search and so
on.

QUESTION 2

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

Correct Answer:
Section: Understand Cloud Concepts
Explanation
Explanation/Reference:
Explanation:
Box 1: Yes
Traditionally, IT expenses have been considered a Capital Expenditure (CapEx). Today, with the move to
the cloud and the pay-as-you-go model, organizations have the ability to stretch their budgets and are
shifting their IT CapEx costs to Operating Expenditures (OpEx) instead. This flexibility, in accounting terms,
is now an option due to the “as a Service” model of purchasing software, cloud storage and other IT related
resources.
Box 2: No
Two virtual machines using the same size could have different disk configurations. Therefore, the monthly
costs could be different.
Box 3: Yes
When an Azure virtual machine is stopped, you don’t pay for the virtual machine. However, you do still pay
for the storage costs associated to the virtual machine. The most common storage costs are for the disks
attached to the virtual machines. There are also other storage costs associated with a virtual machine
such as storage for diagnostic data and virtual machine backups.

D.configuring the SaaS solution
Correct Answer: D
Section: Understand Cloud Concepts
Explanation
Explanation/Reference:
Explanation:
When you are implementing a Software as a Service (SaaS) solution, you are responsible for configuring
the SaaS solution. Everything else is managed by the cloud provider.
SaaS requires the least amount of management. The cloud provider is responsible for managing
everything, and the end user just uses the software.
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 which 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.
