Exam AZ-303 topic 1 question 52 discussion

I think the answer is correct. VM1 and VM2 are part of the same availability set - 99.95% VM3 and VM4 are on the same availability zone, so it can't be 99/99% VM5 and VM6 are across availability zones, 9999% From Azure documentation at https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_8/ For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.99% of the time. For all Virtual Machines that have two or more instances deployed in the same Availability Set, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time. For any Single Instance Virtual Machine using premium storage for all Operating System Disks and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 99.9%.

It should be Y/Y/Y Azure VM SLA Below are the SLA's for the Azure Virtual Machines. 99.9%, Single VM 99.95%, 2 or more VMs in an Availability Set 99.99%, 2 or more VMs into Availability Zone

It does not say anywhere that the coupled VMs provide same services, nor does it ask for SLA of a service or availability set. Hence, as written (perhaps not as intended), none of the configurations improve SLA beyond basic 99.9% provided by the Premium SSD.

I think answer is YNY

Answer is Y/Y/Y. Availability set - 99.95% Availability zone - 99.99%

The Answer should be N/N/N The compond availability on a group of VMs in either a Availability Set or Avaialility Zone is irrelevant as the questions ask specifically about particular VM instances availability. In that case, the SLA for "Single Instance Virtual Machine using Premium SSD or Ultra Disk" applies. It should be all 99.0%

I think the answer should be Y/Y/N. VM1 and VM2 are in AVSET1 which is 99.95% SLA VM3 and VM4 are in the same AZ which means 2 instances in the same AZ which will guarantee 99.99% SLA. Azure availability zones are physically separate locations within each Azure region that are tolerant to local failures. When creating an AZ you can select from 1-3 zones. VM5 is not eligible for 99.99% SLA since it's a single instance of the VM in an AZ. Azure VM SLA Below are the SLA's for the Azure Virtual Machines. 99.9%, Single VM 99.95%, 2 or more VMs in an Availability Set 99.99%, 2 or more VMs into Availability Zone Ref: https://social.technet.microsoft.com/wiki/contents/articles/51828.azure-vms-availability-sets-and-availability-zones.aspx https://docs.microsoft.com/en-us/azure/availability-zones/az-overview

It will be YYY. Please note that is mentioned "premium SSD" and in https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_9/ you will notice the following statement For any Single Instance Virtual Machine using Premium SSD or Ultra Disk for all Operating System Disks and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 99.9%.

why vm7 vm8 list in question?

For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time. For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.99% of the time. https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_9/ Yes No Yes it is

As stated here: https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_9/ Y| N | Y VM1 and VM2 is YES --> For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time. VM3 is NO --> For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.99% of the time. --> Note that they deployed it to the same availability zone VM5 is Yes --> They are not in any AS, AZ, therefore --> For any Single Instance Virtual Machine using Premium SSD or Ultra Disk for all Operating System Disks and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 99.9%.

Answer is Y, For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time. N No SLA guaranteed for 2 machines in same AZ unless they are part of availability set, etc N For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.99% of the time. Note The "two or more instances across two or more AZ..". In the question, it is one instance each across two AZ so th SLA does not hold. BTW, where did examtopics get avset2 in their answer ? Dont see it mentioned in the question ?

My vote goes to Y/N/N - a lot of your are not reading the question properly, they are asking about single VMs.

I had this question in the exam that i took on July 14th 2021

As per the question, one should focus on "Availability option" and "Disk Type" used during VM provisioning. The answer is Y, N, Y, here is the explanation. VM1 - Premium Disk - RG1 - West US - Av Set 1 VM2 - Premium Disk - RG1 - West US - Av Set 1 VM3 - Premium Disk - RG1 - West US - Same Av Zone VM4 - Premium Disk - RG1 - West US - Same Av Zone VM5 - Premium Disk - RG2 - East US2 - Diff Av Zone VM5 - Premium Disk - RG2 - East US2 - Diff Av Zone VM5 - Premium Disk - RG2 - East US2 - None VM5 - Premium Disk - RG2 - East US2 - None 1. VM1 and VM2 are in same Av Set, hence they meet VM Connectivity SLA of at least 99.95% 2. VM3 and VM4 are in same Av Zone, hence they meet VM Connectivity SLA of at least 99.9%, it not 99.99%. 3. VM5 and VM6 are in diff Av Zone, hence they meet VM Connectivity SLA of at least 99.99%

Actually the SLA only cover "Virtual Machine Connectivity to at least one instance", i.e. connect to VM1 or VM2, SLA is not apply to VM1 For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time.
