Question #: 10
Topic #: 1

HOTSPOT -
You have an Azure subscription.
You plan to use Azure Resource Manager templates to deploy 50 Azure virtual machines that will be part of the same availability set.
You need to ensure that as many virtual machines as possible are available if the fabric fails or during servicing.
How should you configure the template? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Show Suggested Answer

Suggested Answer:

Use two fault domains.
2 or 3 is max value, depending on which region you are in.
Use 20 for platformUpdateDomainCount
Increasing the update domain (platformUpdateDomainCount) helps with capacity and availability planning when the platform reboots nodes. A higher number for the pool (20 is max) means that fewer of their nodes in any given availability set would be rebooted at once.

That is correct: 3 and 20> but you can't write "max value" in there... it's a string and the values for those two objects are integer: https://docs.microsoft.com/en-us/azure/templates/Microsoft.Compute/2017-12-01/availabilitysets the second one can be set to 20 (correct) but don't know what to do with the first part, any ideas?

If max value is acceptable for fault domain, you'd think it would be acceptable for update domain also.

The first answer should be 2~3 and the second answer shoud be 20. Because here only integer is valid. 2~3 and 20 are all means Max Value.

I got this question on my exam and it was given the options 1,2,3 as maximum value numbers. it should be three as 3 is valid maximum, and fault domain is 20 so answer is correct.

These awnsers are highly confusing. The requested values can only be INTEGERS, see for ref.: https://docs.microsoft.com/en-us/powershell/module/az.compute/new-azavailabilityset?view=azps-4.8.0 New-AzAvailabilitySet [[-PlatformUpdateDomainCount] <Int32>] [[-PlatformFaultDomainCount] <Int32>] But neither 0 nor 20 can be correct for faultDomain, so you guess to choose "max value". Following this logic why shouldn't I use this too for updateDomains? Ok, you should know that max updateDomains are 20 in any case/region but then they should split the question in two seperates for domain/updateDomains..

Its MAXVALUE for the Fault Domain as 'some' regions support 3 whilst others only 2.

that 'max value' isn't an ambiguous answer.If one had to choose max value at fault domain, he'd choose max value at update domain too and he is logically right! It should be Max FaultDomains: 3 max UpdateDomains: 20
