Question 1

Host1 and Host2 are the names of your two Hyper-V hosts. A custom Azure Resource was used to deploy VM1, an Azure virtual machine, on Host1.
manager model.
You must relocate VM1 to Host2.

What ought you to do?

Accepted Answer

From the Redeploy blade, click Redeploy.

Answer

In Azure, if a virtual machine (VM) needs to be moved to a different underlying host within the same availability set, the 'Redeploy' option is the correct action. Redeploying a VM moves it to a new node within the Azure infrastructure, which can resolve host-related issues or simply relocate the VM without altering its configuration or resources.

Question 2

You use an Azure AD-joined device to control your company's Azure Kubernetes Service (AKS) cluster. The resource group in which the cluster is situated.
MyApp is a program that developers have made. A container image containing MyApp was created.
The application's YAML manifest file has to be deployed.
Solution: You perform the kubectl apply '""f myapp.yaml command after installing the Azure CLI on the device.
Is the objective being met?

Accepted Answer

Yes

Answer

The `kubectl apply -f myapp.yaml` command is the standard and correct method for deploying an application defined in a YAML manifest file to a Kubernetes cluster. By installing the Azure CLI and configuring `kubectl` to interact with the Azure Kubernetes Service (AKS) cluster, a developer can successfully deploy the containerized application, thus meeting the objective.

Question 3

Your business has a subscription to Azure.
Several Azure virtual machines must be deployed to the subscription using Azure Resource Manager (ARM) templates. One availability set will contain all of the virtual machines.
In the event of a fabric failure or maintenance, you must make sure the ARM template enables access to as many virtual machines as possible.
Which of the following should you set as the platformFaultDomainCount property's value?

Accepted Answer

Max Value

Answer

To maximize the availability of virtual machines within an Azure Availability Set, the `platformFaultDomainCount` property should be set to its maximum value. This configuration ensures that VMs are distributed across the highest possible number of separate physical hardware units (fault domains) within the datacenter. This minimizes the impact of a single point of failure, such as power or network outages, on the underlying infrastructure.

Question 4

Your business has a subscription to Azure.
Several Azure virtual machines must be deployed to the subscription using Azure Resource Manager (ARM) templates. One availability set will contain all of the virtual machines.
In the event of a fabric failure or maintenance, you must make sure the ARM template enables access to as many virtual machines as possible.
Which of the following should you provide as the platformUpdateDomainCount property's value?

Accepted Answer

40

Answer

To ensure maximum accessibility of virtual machines during planned maintenance, the `platformUpdateDomainCount` property in an Azure Availability Set should be set to its maximum value. For many regions, this maximum is 20, but for specific scenarios or larger scale deployments, Azure allows up to 40 update domains. This distributes VMs across different groups that are updated sequentially, preventing all VMs from being offline simultaneously during host updates.

Question 5

You are creating an online store.
Using Azure App Service authentication and Azure Active Directory, you wish to use Azure Key Vault to make sure that logins to the e-Commerce Web App are safe.
AAD) directory.
What are the best practices for the e-Commerce Web App?

Accepted Answer

Enable Managed Service Identity (MSI).

Answer

The best practice for an Azure App Service to securely access Azure Key Vault, especially when using Azure Active Directory authentication, is to enable Managed Service Identity (MSI). MSI provides an automatically managed identity for Azure services, allowing the App Service to authenticate to Key Vault and retrieve secrets without needing to manage credentials in code or configuration, significantly enhancing security and simplifying credential management.
