Zorluk: OrtaDesign Compute High Availability

An organization is designing the compute layer for a telemetry processing workload. The workload will run on Azure Virtual Machines.

The design must meet the following requirements:
- Provide a virtual machine uptime SLA of 99.99%99.99\%.
- Protect the workload against localized datacenter outages within an Azure region.
- Minimize network latency between the virtual machine instances.

Which two actions should you include in the design? (Select two.)

  1. Deploy the virtual machines across two or more Availability Zones.Cevap
  2. Associate the virtual machines with a Proximity Placement Group.Cevap
  3. C
    Deploy the virtual machines within a single Availability Zone using an Availability Set.
  4. D
    Deploy the virtual machines as Spot Virtual Machines.

Cevap

Deploy the virtual machines across two or more Availability Zones and associate the virtual machines with a Proximity Placement Group.
To achieve a 99.99%99.99\% SLA and ensure protection against a datacenter-level outage, the virtual machines must be distributed across two or more Availability Zones. To minimize network latency between the virtual machines, a Proximity Placement Group should be used to co-locate the resources as closely as possible.

Adım Adım Çözüm

1
Analyze the SLA and high availability requirements.
The requirement for a 99.99%99.99\% uptime SLA and protection against physical datacenter outages means the virtual machines must be distributed across multiple Azure Availability Zones.
Azure guarantees a 99.99%99.99\% uptime SLA only when two or more VM instances are deployed across two or more Availability Zones in the same region.
2
Analyze the network latency requirement.
The virtual machines must be associated with a Proximity Placement Group (PPG).
A Proximity Placement Group is a logical grouping capability used to ensure that Azure compute resources are physically located close to each other, minimizing network latency.
