Exam 1Y0-403 topic 1 question 89 discussion

Should be B Resource group is not about HA Availability sets with fault domain it does limit the impact of potential physical hardware failures, network outages, or power interruptions. Availability sets with update domain is about restart Availability zones are about multiple azure data-centers https://docs.microsoft.com/en-us/azure/virtual-machines/availability-set-overview https://docs.microsoft.com/en-us/azure/availability-zones/az-overview?context=/azure/virtual-machines/context/context#availability-zones

I think the critical phrase is not "any hardware failure" as that could be B or D, but "in a single Azure data center". Availability Sets - A group consisting of two or more VMs in the same Data Center. Availability zones is a regional solution. Although in Citrix and Microsoft docs both say Availablity sets should only be used when Availability Zones not available. https://www.citrix.com/blogs/2020/12/02/citrix-tips-citrix-on-azure-enterprise-scale-landing-zones-part-3/ https://learn.microsoft.com/en-us/azure/cloud-adoption-framework/scenarios/wvd/landing-zone-citrix/citrix-business-continuity-disaster-recovery But the requirement to be in a single Azure data center points to Availability Sets.

Yes, it should be B! The requirement with HW failure is met: "it does limit the impact of potential physical hardware failures". D is wrong!

B. Availability sets with fault domain for sure.Simple Q from AZ900\104

I think the keywords in the question are "hardware failures at MS Azure". Each availability zone has distinct power source, network, cooling and so on... So D should be right.
