AZ-900: Microsoft Azure Fundamentals
A company needs to create around 50 customized Virtual Machines.
Out of these 20 are Windows based Virtual machines and 30 are Ubuntu Machines.
Which of the following would help reduce the administrative effort required to deploy the machines?
Azure Load Balancer
Azure Web Apps
Azure Traffic Manager
Azure ScaleSets
Answer is Azure ScaleSets. Because Azure virtual machine scale sets let you create and manage a group of identical, load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule.

A company wants to make use of Microsoft Azure for deployment of various solutions.
They want to ensure that whenever users authenticate to Azure, they have to make use of Multi-Factor Authentication (MFA).
Which of the following can help them achieve this?
Azure AD Identity Protection
Azure Security Center
Azure DDoS protection
Azure privileged identity management
Answer is Azure Identity Protection. It is a tool that allows organizations to accomplish three key tasks:
- Automate the detection and remediation of identity-based risks.
- Investigate risks using data in the portal.
- Export risk detection data to third-party utilities for further analysis.

A company is planning on hosting 2 Virtual Machines in Azure as shown below:
| Virtual Machine Name | Virtual Machine Size |
| demo-vm-1 | B1S |
| demo-vm-2 | B1S |
When the virtual machine demovm is stopped, you will still incur costs for the storage attached to the Virtual Machine?
Yes
No
Answer is Yes. Because Azure continues to charge for the VM core hours while it is Stopped (but not Stopped (Deallocated), based on the size of the VM and the image you selected to create it. You continue to accrue charges for the VM’s cloud service and the storage needed for the VM’s OS disk and any attached data disks. Temporary (scratch) disk storage on the VM is free.

A company is planning on setting up a solution within Microsoft Azure.
The solution would have the following key requirement:
- A tool used to monitor Web applications hosted in production based environments
Azure Advisor
Azure Cognitive Services
Azure Application Insights
Azure Devops
Answer is Azure Application Insights. Because it is a a feature of Azure Monitor, is an extensible Application Performance Management (APM) service for web developers on multiple platforms. Use it to monitor your live web application. It will automatically detect performance anomalies. It includes powerful analytics tools to help you diagnose issues and to understand what users actually do with your app. It's designed to help you continuously improve performance and usability. It works for apps on a wide variety of platforms including .NET, Node.js and Java EE, hosted on-premises, hybrid, or any public cloud. It integrates with your DevOps process, and has connection points to a variety of development tools. It can monitor and analyze telemetry from mobile apps by integrating with Visual Studio App Center.

A company needs to implement a solution within Microsoft Azure.
Below are the key requirements for this solution:
- Ability to store JSON documents
- Ensure low latency access to data from around the world
Azure SQL Database
Azure Cosmos DB
Azure SQL Datawarehouse
SQL Server Stretch database
Answer is Azure Cosmos DB. Because this DB is Microsoft's globally distributed, multi-model database service. With a click of a button, Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure regions worldwide providing low latency. You can elastically scale throughput and storage, and take advantage of fast, single-digit-millisecond data access using your favorite API including SQL, MongoDB, Cassandra, Tables, or Gremlin. Cosmos DB provides comprehensive service level agreements (SLAs) for throughput, latency, availability, and consistency guarantees, something no other database service offers. In addition you have the ability to store JSON docs.

A company is planning on deploying Microsoft Azure resources to a Resource Group (RG).
But the resources would belong to different locations.
Can you have resources that belong to the same resource group but be in multiple locations?
Yes
No
Answer is Yes. Because when creating a resource group, you need to provide a location for that resource group. You may be wondering, "Why does a resource group need a location? And, if the resources can have different locations than the resource group, why does the resource group location matter at all?" The resource group stores metadata about the resources. When you specify a location for the resource group, you're specifying where that metadata is stored. For compliance reasons, you may need to ensure that your data is stored in a particular region.

A company wants to have an Enterprise messaging solution integrated with their existing application hosted within Microsoft Azure.
Which of the following from above should the company use for this requirement?
Logic Apps
API Management Services
Service Bus
Data Factories
API Connections
Answer is Service bus. Because Microsoft Azure Service Bus is a fully managed enterprise integration message broker. Service Bus can decouple applications and services. Service Bus offers a reliable and secure platform for asynchronous transfer of data and state.
Data is transferred between different applications and services using messages. A message is in binary format and can contain JSON, XML, or just text.

A company is planning on hosting an application on a set of Virtual Machines.
The Virtual Machines are going to be running for a prolonged duration of time.
Which of the following should be considered to reduce the overall cost of Virtual Machine usage?
Premium Disks
Virtual Machine Scale sets
Azure Reservations
Azure Resource Groups
Answer is Azure Reservation. Because they help you save money by committing to one-year or three-years plans for virtual machines, Azure Blob storage or Azure Data Lake Storage Gen2, SQL Database compute capacity, Azure Cosmos DB throughput, or other Azure resources. Committing allows you to get a discount on the resources you use. Reservations can significantly reduce your resource costs up to 72% on pay-as-you-go prices. Reservations provide a billing discount and don't affect the runtime state of your resources.
If you have virtual machines, Blob storage data, Azure Cosmos DB, or SQL databases that use significant capacity or throughput, or that run for long periods of time, buying a reservation gives you the most cost-effective option. For example, when you continuously run four instances of a service without a reservation, you're charged at pay-as-you-go rates. When you buy a reservation for those resources, you immediately get the reservation discount. The resources are no longer charged at the pay-as-you-go rates.

A company has launched a set of Virtual Machines in their Pay-as-you-go Microsoft Azure subscription.
After launching a set of VM’s they seem to be hitting a constraint of 20 vCPU’s and are not able to provision additional Virtual Machines.
Which of the following can be done to allow the company to provision more Virtual Machines?
Raise a support ticket with Microsoft
Increase the limit in the Azure portal
Increase the limit using the Azure CLI
Increase the limit in Azure Advisor
Answer is Raise a support ticket with Microsoft. Because you get easy access to Azure Support by going online to the Azure Portal and submitting a support request. This is the fastest way to hear back from a Support Engineer that will be ready to start helping you. Access to Subscription Management and billing support is included with your Microsoft Azure subscription, and Technical Support is provided through one of the Azure Support Plans.

A company wants to setup users in within their Microsoft Azure Account.
They have segregated their users into groups.
They now want to ensure they set the right permissions for users and administrators accordingly.
They need to manage the permissions effectively.
You recommend using Azure Policies.
Does this recommendation meet the requirement?
Yes
No
Answer is No. Because Azure Policy is a service in Azure that you use to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements. Azure Policy meets this need by evaluating your resources for non-compliance with assigned policies. All data stored by Azure Policy is encrypted at rest.
