Exam AZ-300 topic 1 question 54 discussion

1 | 2 | 3 4 | 5 | 6 7 | 8 | 9 10| Worst case scenario, the first update domain is being updated meaning 4 out of a total of 10 VMs are updated in that case, leaving us with at minimum 6 available VMs.

See the scenary in a table. VM|FD|UD VM0|0|0 VM1|1|1 VM2|0|2 VM3|1|0 VM4|0|1 VM5|1|2 VM6|0|0 VM7|1|1 VM8|0|2 VM9|1|0 We have this if we thinking in groups of Updated Domain: FD 0|FD 1| VM0|VM3|UD0 VM6|VM9|UD0 VM4|VM1|UD1 -|VM7|UD1 VM2|VM5|UD2 VM8|-|UD2 In summary, we have Update Domain 0(UD0): 4 VM Update Domain 1(UD1): 3 VM Update Domain 2(UD2): 3 VM So in updated planning, we have two options: - The first UD0 is updated, therefore we have 6 VM available. - UD1 or UD2 is updated, therefore we have 7 VM available. In the answer options, we don't have the number 7 like an option, so the answer is 6VM available. Here you have a link to read and try to understand better: https://azure.codefari.com/2018/12/what-are-availability-set-fault-domain.html

FD Starts from 0, so total there are 3 FDs in which VMs would be distributed

Given Answer is correct

"Two out of three update domains would be available, each with at least 3 VMs." I think we will have within the planned maintenance 2*2 =4 vms? We have 3 Update Domains and 2 Fault Domain within the maintenance we have 2 Update Domains with 2 Fault Domains ?? Some ideads?

New VM must be add in same RG. Box 2 is correct. https://social.technet.microsoft.com/wiki/contents/articles/51828.azure-vms-availability-sets-and-availability-zones.aspx
