900: Microsoft Azure Fundamentals
What is the customer responsible for in a software as a service (SaaS) model? - โ โ data and access
SaaS allows you to pay to use an existing application on hardware managed by a third party. You supply data and configure access.
Customers are only responsible for storage in a private cloud.
Customers are responsible for virtual machines and runtime in IaaS and the private cloud.
Your organization is building a custom application.
You need to focus on application development rather than configuration and management of servers.
Which cloud service model should you use? - โ โ platform as a service (PaaS)
With PaaS, users can focus on application development because the cloud provider handles all the platform management.
In SaaS, the cloud provider manages all aspects of the application environment, such as virtual machines, networking resources, data storage, and applications.
IaaS is the closest service model to managing physical servers.
Which cloud service model is used by Microsoft Office 365? - โ โ software as a service (SaaS)
SaaS allows users to connect to and use cloud-based apps over the internet.
Which type of cloud service are virtual networks? - โ
โ infrastructure as a service (IaaS)
IaaS helps you reduce the cost and complexity of maintaining a physical server and its datacenter infrastructure. Virtual networks are part of the IaaS cloud service.
Which two factors affect Azure costs? - โ โ resource usage
resource location
Usage meters, such as CPU time, disk size, and write operations, are used to calculate your bill for an Azure resource. Deleting or deallocating a resource means that you will no longer be billed for it. Different regions can have different associated prices. Resources cost the same no matter the time of day or the day of the week.
You need to compare the costs of running an application in an on-premises datacenter with the costs of running
the application in Azure. - โ โ Total Cost of Ownership (TCO) Calculator
The TCO Calculator helps you estimate the cost savings over time of operating a solution in Azure compared to operating in an on-premises datacenter.
Which two scenarios are common billing use cases for resource tags? - โ โ categorizing costs by department
associating costs with different environments
You can use tags to categorize costs by department, such as human resources, marketing, or finance, or by environment, such as test or production.
You plan to build a new solution in Azure that will use platform as a service (PaaS) products.
What should you use to estimate the monthly costs? - โ
โ Azure Pricing calculator
You have an Azure virtual machine that is accessed only between 9:00 and 17:00 each day.
What should you do to minimize costs but preserve the
associated hard disks and data? - โ โ Deallocate the virtual machine.
If you have virtual machine workloads that are used only during certain periods, but you run them every hour of every day, then you are wasting money. These virtual machines are great candidates to deallocate when not in use and start back when required to save compute costs while the virtual machines are deallocated.
Your organization plans to deploy several production virtual machines that will have consistent resource usage throughout the year.
What can you use to minimize the costs of the virtual machines without reducing the functionality of the virtual machines? - โ โ Azure Reservations
Azure Reservations offers discounted prices on certain Azure services. Azure Reservations can save you up to 72 percent compared to pay-as-you-go prices. To receive a discount, you can reserve services and resources by paying in advance.Spending limits can suspend a subscription when the spend limit is reached.
You need to identify which Azure services are compliant with ISO 27001 Information Security Management Standards.
Where should you go to locate the information? - โ โ Microsoft Trust Center
The Trust Center showcases the Microsoft principles for maintaining data integrity in the cloud and how Microsoft implements and supports security, privacy, compliance, and transparency in all Microsoft cloud products and services.
to create, update, and delete resources in an Azure account.
You need to associate the costs of resources to different groups within an organization without changing the location of the resources. - โ โ resource tags
Resource tags can be used to group billing data and categorize costs by runtime environment, such as billing usage for virtual machines running in a production environment.
What can be applied to a resource to prevent accidental
deletion? - โ โ a resource lock
A resource lock prevents resources from being accidentally deleted or changed. Resource tags offer the custom grouping of resources.
Policies enforce different rules across all resource configurations so that the configurations stay compliant
with corporate standards. An initiative is a way of grouping related policies together.
What can you use to ensure that new and existing Azure resources stay in compliance with corporate standards? - โ โ Azure Policy
Azure Policy is a service in Azure that enables you to create, assign, and manage policies that control or audit resources.
These policies enforce different rules across all resource configurations so that the configurations stay compliant with corporate standards.
You need to ensure that multi-factor authentication (MFA) is enabled on accounts with write permissions in an Azure subscription.
What should you implement? - โ โ Azure Policy
Azure CLI is an executable program with which a user can execute commands in Bash that call the Azure REST API.
Azure Cloud Shell also supports Azure PowerShell as an executable program.
What can you use to create resources in Azure and includes a validation step to ensure all resources are created in a specific order based on dependencies, in
parallel and idempotent? - โ โ Azure Resource Manager (ARM) templates
ARM templates define an application's infrastructure requirements for a repeatable deployment that is done in a consistent manner. A validation step ensures that all resources can be created in the proper order based on dependencies, in parallel and idempotent.
What can you use to manage servers across cloud platforms and on-premises environments? - โ โ Azure Arc
Azure Arc simplifies governance and management by delivering a consistent multi-cloud and on-premises management platform.
Which Azure service evaluates Azure resources and makes recommendations to help improve reliability,
security, performance, and cost reduction? - โ โ Azure Advisor
Azure Advisor evaluates Azure resources and makes recommendations to help improve reliability, security, and performance, achieve operational excellence, and reduce costs.
You need to be notified when there are new recommendations for reducing Azure costs.
Which tool should you use? - โ โ Azure Advisor
Azure Advisor evaluates Azure resources and makes recommendations to help improve reliability, security,
What can you use to find information about planned maintenance for Azure services that are critical to your organization? - โ โ Azure Service Health
You can drill down to the affected services, regions, and details to show how an event will affect you and what you must do.
Most of these events occur without any impact to you and will not be shown. In a rare case that a reboot is required,
Service Health allows you to choose when to perform the maintenance to minimize the downtime
For which resource does Azure generate separate billing reports and invoices by default? - โ โ subscriptions
Azure generates separate billing reports and invoices for each subscription so that you can organize and manage costs.
Resource groups can be used to group costs, but you will not receive a separate invoice for each resource group.
Management groups are used to efficiently manage access, policies, and compliance for subscriptions.
You can set up billing profiles to roll up subscriptions into invoice sections, but this requires customization.
Which resource can you use to manage access, policies, and compliance across multiple subscriptions? - โ โ management groups
Management groups can be used in environments that have multiple subscriptions to streamline the application of governance conditions.
Which Azure compute service can you use to deploy and manage a set of identical virtual machines? - โ โ Azure Virtual Machine Scale Sets
What can you use to execute code in a serverless environment? - โ โ Azure Functions
Azure Functions allows you to run code as a service without having to manage the underlying platform or infrastructure.
Azure Logic Apps is similar to Azure Functions, but uses predefined workflows instead of developing your own code.
Which scenario is a use case for a VPN gateway? - โ โ connecting an on-premises datacenter to an Azure virtual network
(for example ExpressRoute one vpn gateway that is used to connect an on-premises network to Azure)
What can you use to connect Azure resources, such as Azure SQL databases, to an Azure virtual network? - โ
โ service endpoints
Service endpoints are used to expose Azure services to a virtual network, providing communication between the two.
ExpressRoute is used to connect an on-premises network to Azure. NSGs allow you to configure inbound and outbound rules for virtual networks and virtual machines. Peering allows you to connect virtual networks together
