The safer , easier way to help you pass any IT exams.
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.

You have an on-premises network that contains several servers. You plan to migrate all the servers to Azure.
You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period.
What should you include in the recommendation?
- A: fault tolerance
- B: elasticity
- C: scalability
- D: low latency
Correct Answer: A
In this question, you could have servers that are replicated across datacenters.
Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures.
With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter.
If one zone is compromised, then replicated apps and data are instantly available in another zone.

This question requires that you evaluate the underlined text to determine if it is correct. An organization that hosts its infrastructure in a private cloud can close its data center.
Instructions: Review the underlined text. If it makes the statement correct, select “No change is needed”.
If the statement is incorrect, select the answer choice that makes the statement correct.
- A: No change is needed.
- B: in a hybrid cloud
- C: in the public cloud
- D: on a Hyper-V host
Correct Answer: C
A public cloud is hosted externally, for example, in Microsoft Azure. An organization that hosts its infrastructure in a public cloud can close its data center.
Public cloud is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date – everything runs on your cloud provider's hardware.
Microsoft Azure is an example of a public cloud provider.
In a private cloud, you create a cloud environment in your own datacenter and provide self-service access to compute resources to users in your organization. This offers a simulation of a public cloud to your users, but you remain completely responsible for the purchase and maintenance of the hardware and software services you provide.

What are two characteristics of the public cloud? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.
- A: dedicated hardware
- B: unsecured connections
- C: limited storage
- D: metered pricing
- E: self-service management
Correct Answer: DE
Incorrect Answers:
A: You don’t have dedicated hardware. The underlying hardware is shared so you could have multiple customers using cloud resources hosted on the same physical hardware.
B: Connections to the public cloud are secure.
C: Storage is not limited. You can have as much storage as you like.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
Your company plans to migrate all its data and resources to Azure.
The company’s migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure.
You need to deploy an Azure environment that meets the company migration plan.
Solution: You create an Azure App Service and Azure SQL databases.
Does this meet the goal?
- A: Yes
- B: No
Correct Answer: A

Your company plans to migrate all its data and resources to Azure.
The company’s migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure.
You need to deploy an Azure environment that meets the company migration plan.
Solution: You create an Azure App Service and Azure virtual machines that have Microsoft SQL Server installed.
Does this meet the goal?
- A: Yes
- B: No
Correct Answer: B
However, Azure virtual machines are an IaaS (Infrastructure as a Service) service. Therefore, this solution does not meet the goal.

Solution: You create an Azure App Service and Azure Storage accounts.
Does this meet the goal?
- A: Yes
- B: No
Correct Answer: B
However, Azure Storage accounts are an IaaS (Infrastructure as a Service) service. Therefore, this solution does not meet the goal.
Your company hosts an accounting application named App1 that is used by all the customers of the company.
App1 has low usage during the first three weeks of each month and very high usage during the last week of each month.
Which benefit of Azure Cloud Services supports cost management for this type of usage pattern?
- A: high availability
- B: high latency
- C: elasticity
- D: load balancing
Correct Answer: C
Elastic computing is the ability to quickly expand or decrease computer processing, memory and storage resources to meet changing demands without worrying about capacity planning and engineering for peak usage. Typically controlled by system monitoring tools, elastic computing matches the amount of resources allocated to the amount of resources actually needed without disrupting operations. With cloud elasticity, a company avoids paying for unused capacity or idle resources and doesn’t have to worry about investing in the purchase or maintenance of additional resources and equipment.

You plan to migrate a web application to Azure. The web application is accessed by external users. You need to recommend a cloud deployment solution to minimize the amount of administrative effort used to manage the web application.
What should you include in the recommendation?
- A: Software as a Service (SaaS)
- B: Platform as a Service (PaaS)
- C: Infrastructure as a Service (IaaS)
- D: Database as a Service (DaaS)
Correct Answer: B
