this is the way the site is suppose to run because if this site give all the correct answers then MS will shut it down. that is why you need to read the discussions and analyze the answer by yourself.

i started thinking the same, if they had only current questions and 100% correct answers MS might sue them. and if they are out of country MS could petition backbone companies to block/remove the site. that's why you see some websites changing domains almost monthly like .to .is. net. .cc and etc. cloudflare received complains about 35k domains in 2021 and actioned a significant amount of them. so the old times of needing to nuke the website itself are gone.

Selected Answer: A
In an Azure Availability Set, update domains (UDs) help ensure that virtual machines (VMs) remain accessible during planned maintenance. The platformUpdateDomainCount property defines the number of update domains within an availability set. Update domains help distribute VMs so that Azure does not restart all VMs at once during maintenance. The maximum number of update domains supported in Azure is 20, but the default is 5, and the recommended value is 10 for most cases.

Answer is A. To maximize VM availability during maintenance and minimize downtime in the event of fabric failure, you should configure the platformUpdateDomainCount property to 10 (Option A). This will distribute your VMs across 10 update domains, ensuring that as many VMs as possible remain unaffected during planned maintenance and providing optimal availability.

Answer is B, it specifically mentions the domain max count; "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. These configurations can't be changed once the availability set has been created. source- https://learn.microsoft.com/en-us/azure/virtual-machines/availability-set-overview

Answer: B Each availability set can be configured with up to 3 fault and 20 update domains. So, the best value you could configure against the update domain will be its maximum of 20.
