SLA for Virtual Machines Last updated: July 2020 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 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 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%. For any Single Instance Virtual Machine using Standard SSD Managed Disks for Operating System Disk and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 99.5%. For any Single Instance Virtual Machine using Standard HDD Managed Disks for Operating System Disks and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 95%.

The correct answer is B. The correct solution would have a minimum of 2 for both.

yes correct

The given solution meets the 99.99% availability requirement while using the minimum required VMs and Availability Zones.

a - yes SLA for Virtual Machines | Azure

orrekte Lösung: ✅ Mindestens zwei virtuelle Maschinen in zwei verschiedenen Verfügbarkeitszonen ✅ Azure Load Balancer, um den Datenverkehr zwischen den VMs zu verteilen

Having Two Vms and Two Availability ZOne ensures no downtime and SLA is 99.9%.

A. Yes Deploying two virtual machines across two availability zones can meet the goal of achieving 99.99% availability. Here’s why: Availability Zones: Using two availability zones provides high availability by ensuring that if one zone experiences a failure, the other zone can continue to operate, thereby reducing the risk of total service disruption. Virtual Machines: With two virtual machines spread across these availability zones, you achieve redundancy and fault tolerance. If one virtual machine fails, the other can handle the workload, ensuring continuous operation. This setup meets the requirements for high availability with minimal resource use, aligning with the goal of 99.99% availability. So, the correct answer is A. Yes.

Its A the right answer

yes 2 vm and 2 Available zone

it's A Two virtual machines and two availability zones meet the 99.9%

Having 2 VMs at two different locations/availability zones solves the problem.

Answer is A

A - 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.

A

The answer is A. Yes The solution meets the goal. Deploying two virtual machines across two availability zones is a suitable strategy for achieving a guaranteed availability of 99.99 percent with the least virtual machines and availability zones. Azure Availability Zones are physically separate datacenters within an Azure region, providing redundancy and high availability. By deploying the application to two virtual machines, each in a different availability zone, you ensure that even if one availability zone experiences an issue, the application remains available in the other availability zone. This setup minimizes the risk of downtime and meets the specified availability requirement of 99.99 percent.

No, the solution does not meet the goal. To achieve a guaranteed availability of 99.99%, you need to deploy your virtual machine in at least three availability zones. This is because Azure guarantees a 99.99% availability SLA for virtual machines that are deployed in three availability zones.
