Question 89

Scenario: The IT team of a company needs to mitigate the Hardware Layer to Microsoft Azure. The Virtual Delivery Agent (VDA) machines are manually provisioned within Microsoft Azure. The IT team asks a Citrix Architect for a solution for high availability of existing VDA machines in a single Azure data center.

The objective is to be proactive about any hardware failure at Microsoft Azure, so that all virtual machines (VMs) will NOT be affected.

What should the architect recommend the IT team create in Microsoft Azure?

    Correct Answer: B

    To proactively mitigate any hardware failure within a single Azure data center and ensure high availability of existing Virtual Delivery Agent (VDA) machines, the IT team should create Availability Sets with fault domain. Availability Sets with fault domain distribute the VMs across multiple fault domains within a single data center, reducing the impact of potential physical hardware failures, network outages, or power interruptions on all the VMs. This setup ensures that even if hardware issues occur, not all VMs will be affected simultaneously.

Discussion
Kada1111Option: B

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

jdstroyOption: B

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!

d0bermannnOption: B

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

cris66Option: B

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.

jdstroyOption: D

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.

AvZones intented for multiple datacenters, we have one dc, so answer is AvSets [with FD]
