AZ-900: Microsoft Azure Fundamentals
You are managing one of your Azure services remotely from your Android phone. Which management tools would best allow you to do manage remotely from your Android phone with the least amount of administrative effort?
Azure CLI
Azure portal
Powershell
Answer is Azure Portal.The Azure portal is the web-based portal for managing Azure. Being web-based, you can use the Azure portal on an iPhone.
Azure Cloud Shell is a web-based command line for managing Azure. You access the Azure Cloud Shell from the Azure portal. Being web-based, you can also use the Azure Cloud Shell on an iPhone.
Which of the following terms ensure that both data-residency and compliance needs are met for customers who need to keep their data and applications close?
Geographies
Regions
Zones
Answer is Geographies. Geographies allow customers with specific data-residency and compliance needs to keep their data and applications close. Geographies ensure that data residency, sovereignty, compliance, and resiliency requirements are honored within geographical boundaries.
A company is planning on deploying an Azure Web App to 2 regions.
One of the key requirements is to ensure that the web app is always running if an Azure region fails. You need to ensure deployment costs are minimized.
Which of the following service would you include in the deployment of the solution?
Azure Functions
Azure Traffic Manager
Azure Application Gateway
Azure Load Balancer
Answer is Azure Traffic Manager

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

To complete the sentence, select the appropriate option in the answer area.
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.

What are two characteristics of the public cloud?
dedicated hardware
unsecured connections
limited storage
metered pricing
self-service management
Answers are; metered pricing
self-service management
With the public cloud, you get pay-as-you-go pricing you pay only for what you use, no CapEx costs.
With the public cloud, you have self-service management. You are responsible for the deployment and configuration of the cloud resources such as virtual machines or web sites. The underlying hardware that hosts the cloud resources is managed by the cloud provider.
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.

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?
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)
Database as a Service (DaaS)
Answer is Platform as a Service (PaaS)
Azure App Service is a platform-as-a-service (PaaS) offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises. App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile Services.

Which cloud deployment solution is used for Azure virtual machines and Azure SQL databases?
To answer, select the appropriate options in the answer area.
Box 1:
Azure virtual machines are Infrastructure as a Service (IaaS).
Infrastructure as a Service is the most flexible category of cloud services. It aims to give you complete control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems). Instead of buying hardware, with IaaS, you rent it.
Box 2:
Azure SQL databases are Platform as a Service (Paas).
Azure SQL Database is a fully managed Platform as a Service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. Azure SQL Database is always running on the latest stable version of SQL Server Database Engine and patched OS with 99.99% availability. PaaS capabilities that are built-in into Azure SQL database enable you to focus on the domain specific database administration and optimization activities that are critical for your business.

You plan to extend your company's network to Azure. The network contains a VPN appliance that uses an IP address of 131.107.200.1.
You need to create an Azure resource that defines the VPN appliance in Azure.
Which Azure resource should you create?
A Local Network Gateway is an object in Azure that represents your on-premise VPN device. A Virtual Network Gateway is the VPN object at the Azure end of the VPN. A connection is what connects the Local Network Gateway an the Virtual Network Gateway to bring up the VPN.
The local network gateway typically refers to your on-premises location. You give the site a name by which Azure can refer to it, then specify the IP address of the on-premises VPN device to which you will create a connection. You also specify the IP address prefixes that will be routed through the VPN gateway to the VPN device. The address prefixes you specify are the prefixes located on your on-premises network. If your on-premises network changes or you need to change the public IP address for the VPN device, you can easily update the values later.
