Question 23 of 50

What can you use to connect Azure resources, such as Azure SQL databases, to an Azure virtual network?

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.

Communicate between Azure resources

You'll want to enable Azure resources to communicate securely with each other. You can do that in one of two ways:

  • Virtual networks can connect not only VMs but other Azure resources, such as the App Service Environment for Power Apps, Azure Kubernetes Service, and Azure virtual machine scale sets.
  • Service endpoints can connect to other Azure resource types, such as Azure SQL databases and storage accounts. This approach enables you to link multiple Azure resources to virtual networks to improve security and provide optimal routing between resources.

 

 

Question 27 of 50

Which Azure Blob storage tier stores data offline and offers the lowest storage costs and the highest costs to access data?

The Archive storage tier stores data offline and offers the lowest storage costs, but also the highest costs to rehydrate and access data. The Hot storage tier is optimized for storing data that is accessed frequently. Data in the Cool access tier can tolerate slightly lower availability, but still requires high durability, retrieval latency, and throughput characteristics similar to hot data.

Blob storage tiers

Azure Storage offers different access tiers for your blob storage, helping you store object data in the most cost-effective manner. The available access tiers include:

  • Hot access tier: Optimized for storing data that is accessed frequently (for example, images for your website).
  • Cool access tier: Optimized for data that is infrequently accessed and stored for at least 30 days (for example, invoices for your customers).
  • Cold access tier: Optimized for storing data that is infrequently accessed and stored for at least 90 days.
  • Archive access tier: Appropriate for data that is rarely accessed and stored for at least 180 days, with flexible latency requirements (for example, long-term backups).

 

Question 40 of 50

Which two actions can be performed by using the graphical user interface (GUI) in the Azure portal? Each correct answer presents a complete solution.

Create new resources.

Review a graphical view of all the services you are using.

The Azure portal provides a GUI to view all the services you are using, create new services, configure your services, and view reports.

Question 41 of 50

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)

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.

When a user sends a request from any of the Azure tools, APIs, or SDKs, ARM receives the request. ARM authenticates and authorizes the request. Then, ARM sends the request to the Azure service, which takes the requested action. You see consistent results and capabilities in all the different tools because all requests are handled through the same API.

 

Question 49 of 50

What can you use to get notification about an outage in a specific Azure region?

Service Health notifies you of Azure-related service issues, such as region-wide downtime.

Describe monitoring tools in Azure - Training | Microsoft Learn

Azure service health does this by combining three different Azure services:

  • Azure Status is a broad picture of the status of Azure globally. Azure status informs you of service outages in Azure on the Azure Status page. The page is a global view of the health of all Azure services across all Azure regions. It’s a good reference for incidents with widespread impact.
  • Service Health provides a narrower view of Azure services and regions. It focuses on the Azure services and regions you're using. This is the best place to look for service impacting communications about outages, planned maintenance activities, and other health advisories because the authenticated Service Health experience knows which services and resources you currently use. You can even set up Service Health alerts to notify you when service issues, planned maintenance, or other changes may affect the Azure services and regions you use.
  • Resource Health is a tailored view of your actual Azure resources. It provides information about the health of your individual cloud resources, such as a specific virtual machine instance. Using Azure Monitor, you can also configure alerts to notify you of availability changes to your cloud resources.
