Exam AZ-305 topic 8 question 1 discussion

I am confident the answer is 3-3. I had this question in my exam today, and I passed the exam with 979. In Design Infrastructure Solutions section, I got 100% correct.

3-3 VMSS supports zone-redundant, while Dedicated Host does not. No-zone option of host group in Dedicated Host is not zone-redundant, it represents regional resource. - You must create a host group in each zone. - You must create a VMSS in each zone where the host group is deployed. https://learn.microsoft.com/en-us/azure/reliability/availability-zones-service-support#azure-services-with-availability-zone-support https://learn.microsoft.com/en-us/azure/virtual-machines/dedicated-hosts#virtual-machine-scale-set-support In addition, when a Host Groups is deployed in each zone, creating a zone-redundant VMSS is also not possible. All tested with multiple hosts, FSv2 Type1.

CORRECT

Automatic VM placement needs to be enabled. The availability setting of your host group should match your scale set. A regional host group (created without specifying an availability zone) should be used for regional scale sets. The host group and the scale set must be using the same availability zone. The fault domain count for the host group level should match the fault domain count for your scale set. The Azure portal lets you specify max spreading for your scale set, which sets the fault domain count of 1. Dedicated hosts should be created first, with sufficient capacity, and the same settings for scale set zones and fault domains. The supported VM sizes for your dedicated hosts should match the one used for your scale set.

Exam Question 02/15/2023

3-3 https://learn.microsoft.com/en-us/azure/virtual-machines/dedicated-hosts#groups-hosts-and-vms A host group is created in a single availability zone. Once created, all hosts will be placed within that zone. To achieve high availability across zones, you need to create multiple host groups (one per zone) and spread your hosts between them accordingly. If you assign a host group to an availability zone, all VMs created on that host must be created in the same zone. When creating a Virtual Machine Scale Set, you can specify an existing host group to have all of the VM instances created on dedicated hosts.

3 and 3

Based on https://learn.microsoft.com/en-us/azure/virtual-machines/dedicated-hosts#virtual-machine-scale-set-support i would say it's 3-3

3-3 Looks correct as per article: https://learn.microsoft.com/en-us/azure/virtual-machines/dedicated-hosts#groups-hosts-and-vms

Maybe this Testlet can be merged with Topic 5 - Testlet 1? Case looks identical (questions are different)

what are the correct answer folks? what have changed on 10th Oct?

3-3 "If the VM is in an availability zone, it must be the same availability zone as the host group. The availability zone settings for the VM and the host group must match" https://learn.microsoft.com/en-us/azure/virtual-machines/dedicated-hosts-how-to?tabs=portal

should be 3 1
