Exam AZ-104 topic 4 question 63 discussion

first box: platformFaultDomainCount should be 3 (since its in East US) ref: https://stackoverflow.com/questions/49779604/how-to-find-maximum-update-domains-fault-domains-available-in-an-azure-region second box: platformUpdateDomainCount = 20

Number of Fault Domains per region Region Max # of Fault Domains East US 3 East US 2 3 West US 3 West US 2 2 Central US 3 North Central US 3 South Central US 3 West Central US 2 Canada Central 3 Canada East 2 North Europe 3 West Europe 3 UK South 2 UK West 2 East Asia 2 South East Asia 2 Japan East 2 Japan West 2 South India 2 Central India 2 West India 2 Korea Central 2 Korea South 2 UAE North 2 China East 2 China East 2 2 China North 2 China North 2 2 Australia East 2 Australia Southeast 2 Australia Central 2 Australia Central 2 2 Brazil South 2 US Gov Virginia 2 US Gov Texas 2 US Gov Arizona 2 US DoD Central 2 US DoD East 2 Ref: https://github.com/MicrosoftDocs/azure-docs/blob/master/includes/managed-disks-common-fault-domain-region-list.md#number-of-fault-domains-per-region

platformFaultDomainCount: 3 platformUpdateDomainCount: 20

Since the maximum FD has always been 3 and UD has always been 20, I'm going with 3 and 20, they are not going to expect you to remember the max per region.

WRONG 3 20

2 and 20

- 3 - 20

Another ridiculous question, how can we remember all the maximum number of fault domain for each region?

https://www.azurespeed.com/Information/AzureAvailabilityZones - All availability zones are now 3. Probably best other ref for answer. https://learn.microsoft.com/en-us/azure/virtual-machines/availability-set-overview#how-do-availability-sets-work "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 3 fault domains and 20 update domains."

On the Exam 3/29/23.

as many virtual machines as possible are available if the fabric fails or during servicing. - With FD=2, only 25 VMs will be available. With FD=3, you get 33 VMs on fault. So FD=3 is better option than FD=2. As for UPD, UPD=max (UPD)=20.

3 FD 20 UD

I took Exam of Azure- 104 at 27/2/2023 I score 920 points out of 1000 points. This was on it and my answer was: Max. Fault domain=3 Max. Update domain =20 its none sense to remember and memorize the number of Fault Domains per region lol

Max. Fault domain=3 Max. Update domain =20

1. 3 2. 20 https://learn.microsoft.com/en-us/azure/virtual-machines/availability-set-overview#how-do-availability-sets-work 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.

In each availability set: - Maximum platformFaultDomainCount is 2 or 3, depending on the region you are deploying in.\ - Maximum platformUpdateDomainCount is 20. These regions have 3 Fault Domains: * East US * East US 2 * West US * Central US * North Central US * South Central US * Canada Central * North Europe * West Europe The rest have 2 Fault Domains.

I say select the maximum number for both Fault domains and update domains. Box1: 3 Box2: 20
