• Chose B1

  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.

• Chose B5

  A single availability zone still creates a single point of failure. For 99.99% availability, Microsoft requires at least two VMs deployed across two or more availability zones in the same region. Correct Strategy: ✅ Deploy two or more VMs in two availability zones using an availability set or zone redundancy. This ensures high availability even if one zone goes down.

• Chose B1

  No, the solution does not meet the goal of guaranteeing an availability of 99.99 percent. In Azure, achieving a Service Level Agreement (SLA) of 99.99 percent availability for virtual machines typically requires deploying them across at least two availability zones. This is because availability zones are designed to provide high availability by isolating resources in separate physical locations within a region, protecting against zone-level failures. If you only include one availability zone, the virtual machines would be susceptible to outages that affect that zone, thereby compromising the availability guarantee. To meet the 99.99 percent availability requirement, you should deploy at least two virtual machines across two different availability zones. This configuration ensures that if one zone experiences an issue, the other zone can continue to operate, thus maintaining the required level of availability for the critical line-of-business application.
