What is high availability in a public cloud environment dependent on?
the service-level agreement (SLA) that you choose
Describe the benefits of using cloud services
Different services have different SLAs. Sometimes different tiers of the same service will offer different SLAs, which can increase or decrease the promised availability.
In which two deployment models are customers responsible for managing operating systems that host applications?
infrastructure as a service (IaaS)
on-premises
Describe cloud service types
Operating systems are managed by customers when using IaaS or an on-premises deployments. The operating systems are not accessible in PaaS and SaaS deployments.
Which Azure component allows you to replicate resources across a geography to ensure business continuity during a natural disaster at the primary site?
region pairs
Describe the core architectural components of Azure
Region pairs allow the replication of Azure resources across geographies to help ensure that a secondary region is available in case of any disaster at the primary region.
Which resource can you use to manage access, policies, and compliance across multiple subscriptions?
management groups
Describe the core architectural components of Azure
Management groups can be used in environments that have multiple subscriptions to streamline the application of governance conditions. Resource groups can be used to organize Azure resources. Administrative units are used to delegate the administration of Microsoft Entra resources, such as users and groups. Accounts are used to provide access to resources.
What can you use to connect Azure resources, such as Azure SQL databases, to an Azure virtual network?
service endpoints
Describe Azure compute and networking services
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.
Which two services can you use to establish network connectivity between an on-premises network and Azure resources?
Azure VPN Gateway
ExpressRoute
Describe Azure compute and networking services
ExpressRoute connections and Azure VPN Gateway are two services that you can use to connect an on-premises network to Azure. Bastion provides a web interface to remotely administer Azure virtual machines by using SSH/RDP. Azure Firewall is a stateful firewall service used to protect virtual networks.
What can be applied to a resource to prevent accidental deletion?
a resource lock
Describe features and tools in Azure for governance and compliance
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.
You need to ensure that multi-factor authentication (MFA) is enabled on accounts with write permissions in an Azure subscription. What should you implement?
Azure Policy
Describe features and tools in Azure for governance and compliance
Azure Policy is a service in Azure that enables you to create, assign, and manage policies that control or audit resources.
What can you use to restrict the deployment of a virtual machine to a specific location?
Azure Policy
Describe the purpose of Azure Policy
Azure Policy can help to create a policy for allowed regions, which enables you to restrict the deployment of virtual machines to a specific location.
Which management layer accepts requests from any Azure tool or API and enables you to create, update, and delete resources in an Azure account?
Azure Resource Manager (ARM)
Describe features and tools for managing and deploying Azure resources
ARM is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in an Azure account.
Which two tools are accessible via Azure Cloud Shell to manage an Azure environment?
Azure CLI
Azure PowerShell
Describe features and tools for managing and deploying Azure resources
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.
Which two factors affect Azure costs?
resource location
resource usage
Describe cost management in Azure
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.
What can you use to find information about planned maintenance for Azure services that are critical to your organization?
Azure Service Health
Describe monitoring tools in Azure
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.
What can you use to ensure that a user can only access applications from compliant devices?
Conditional Access
Describe Azure identity, access, and security
Conditional Access is a feature that Microsoft Entra uses to allow or deny access to resources based on identity signals, such as the device being used. SSO enables a user to sign in one time and use that credential to access multiple resources and applications from different providers. MFA is a process whereby a user is prompted during the sign-in process for an additional form of identification. Hybrid identity solutions create a common user identity for authentication and authorization to all resources, regardless of location.
Which are two common scenarios for using resource tags?
associating costs w/ different environments
(associating costs with different environments)
categorizing costs by department
Describe cost management in Azure
You can use tags to categorize costs by department, such as human resources, marketing, or finance, or by environment, such as test or production. Resizing underutilized virtual machines is a good cost saving measure and provisioning resources in lower cost regions is a good practice, but resource tags do not help with this.
Which two tools can you use to create a new Azure virtual machine from a mobile device that runs Android?
PowerShell in Azure Cloud Shell
the Azure portal
Describe features and tools for managing and deploying Azure resources
The Azure portal can run on devices that have the Android operating system installed. The browser can be any type, such as Internet Explorer 11, Chrome, Firefox, or Safari (all the latest versions). When you visit the portal, you will see Cloud Shell. Users can then access Bash and PowerShell from within Cloud Shell. You can use Bash and PowerShell to create Azure virtual machines.
