Exam AZ-204 topic 1 question 6 discussion

Answer D Max Value. [ values could be 1,2,3 ] https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-manage-fault-domains

As described here: https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-manage-fault-domains You can set the parameter --platform-fault-domain-count to 1, 2, or 3 (default of 3 if not specified). And as described here: https://docs.microsoft.com/en-us/azure/virtual-machines/availability-set-overview Each virtual machine in your availability set is assigned an update domain and a fault domain by the underlying Azure platform. Each availability set can be configured with up to three fault domains and twenty update domains. So answer is D Max Value

az vmss create \ --resource-group myResourceGroup \ --name myScaleSet \ --orchestration-mode Flexible \ --image Ubuntu2204 \ --admin-username azureuser \ --platform-fault-domain-count 3\ --generate-ssh-keys

Why is that relevant for the az-204? Is it not only an infrastructure question?

Setting the platformFaultDomainCount property to the maximum value ensures that the virtual machines are distributed across the maximum number of fault domains. This maximizes the availability of the VMs in the event of a fabric failure or maintenance

you should configure the platformFaultDomainCount property to its maximum value, which is 3 for most regions in Azure. The platformFaultDomainCount property specifies the number of fault domains to use for the availability set. By configuring it to its maximum value, the virtual machines will be distributed across multiple fault domains, which will help ensure that as many virtual machines as possible remain accessible in the event of a failure or maintenance event.

The platformFaultDomainCount property in an Azure Resource Manager (ARM) template specifies the number of fault domains for the Azure virtual machines within an availability set. Fault domains are distinct groups of hardware within a datacenter. When you deploy virtual machines within an availability set, Azure ensures that each VM is placed into a different fault domain to minimize the impact of hardware failures or maintenance events. The maximum value allowed for platformFaultDomainCount depends on the region where you're deploying your resources. It varies across Azure regions. Typically, the maximum value is either 2 or 3. Therefore, to ensure that the ARM template allows for as many virtual machines as possible to remain accessible in the event of fabric failure or maintenance, you should configure

D. Max Value (As per the requirement)

Azure allows you to specify a platform fault domain count of up to 3, which means that there can be up to three fault domains in an availability set. This setting helps distribute the virtual machines across multiple fault domains, reducing the risk of simultaneous failure due to hardware issues. Therefore, you should set it to the maximum value of 3 for optimal fault tolerance.

Answer is D

For domain count, use D. Max value (Available options are 1, 2, 3)

D Max value

Max value is Correct

Answer D Max Value

Answer is D

Each virtual machine in your availability set is assigned an update domain and a fault domain by the underlying Azure platform. Each availability set can be configured with up to three fault domains and twenty update domains. Update domains indicate groups of virtual machines and underlying physical hardware that can be rebooted at the same time.
