Given answer is correct. Box 1: 99,95 bc of the avail set Box 2: no 99,99 bc same avail zone Box 3: different avail zone - so 99,99

I agree with Box 1 and Box 2. What I cannot understand is for Box 3. It is no where mentioned that VM5 and VM6 are replicated server. It's just a server with Premium SSD in different avaibility zone. So should it not be 99.90 and hence False?

You also entrapped yourself by not reading the answer properly. They are asking about single VMs. In this form the answer is N N N

They're asking about "Eligibility" ("VM1 is Eligible for") means we need to answer what is their eligibility where they're part of an AVSET, AVZONE etc.,. I think given answer is correct.

actually, the way the statements are provided, none of them are eligible for those SLAs. The statements mention a single instance VM, so those on premium SSD have 99,9% SLA https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_9/

you missed this: VM1 and VM2 are in an availability set named AVSET1. VM3 and VM4 are in the same availability zone and are in an availability set named AVSET2. VM5 and VM6 are in different availability zones.

I didn't miss it. The fact they are in AVSET does not change a thing since the statement is about a single instance, not the avset. Take a look at the link I provided, it clearly says that SLA of 99,95% is guaranteed for at least one of the VMs in the set, not any particular one, like it's mentioned in the question's statement.

read the SLA statements again, as long as we have two or more VM in an AVSET, the SLA will be 99.95%, it doesn't matter what kind of disk you are using.

You are not reading widurr's comment correctly. The questions are either badly worded or deliberately misleading - the availability sets/zones are not relevant because the question is only asking whether individual VMs are available, not "any VM in the availability zone/set". An individual VM does not have an SLA of 99.95%+

NNN The question asks about single VM's " 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%." https://www.azure.cn/en-us/support/sla/virtual-machines/

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.

No- No- No VMs have a max SLA of 99.9 (premium disks), no matter if they are in availability sets or zones. The *service* will be 99.96% or 99.99%, *not the VM*.

I think the question is not clear or tricky. Deploying virtual machines in different zones will not make the VM itself eligible for SLA 99.99. The service/app in the machines is the one that will be eligible. What do you think guys?

Supposing that (vm1 - vm2), (vm3 - vm4) and (vm5-vm6) are two instances of the same server, then answers are N - N - Y. If every single VM is a single instance, then answers are N - N - N

NO... "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%." 99.9% IS VERY DIFFERENT TO 99.99% https://azure.microsoft.com/en-us/support/legal/sla/virtual-machines/v1_9/

Claudio82 is right, they ask uus about single VMs SLA inthe questions. Not about SLA for an availability set or availability zone. If they ask about VM3 (single VM instance) it does not matter if it is placed in avSet or avZone. It is still only one unique VM instance. The link you provided explains it clearly. There such single instances are described using sentences starting from: For any Single Instance Virtual Machine.... And for all of them,best SLA is not grather as 99,9%... That is why Claudio82 is right.

I agree with this. I think people are over thinking the question. It's saying the VMs are eligible for those SLA's, which the article above confirms. If you look at the article below, it says you should use an AS for a highly available application. So you should only deploy an availability set if your application supports this, otherwise no point using AS in the first place. https://docs.microsoft.com/en-us/azure/virtual-machines/availability-set-overview#what-is-an-availability-set
