Zorluk: OrtaDesign Compute High Availability

You are designing the compute infrastructure for a manufacturing telemetry processing service. The service will run on Azure Virtual Machines.

The requirements are as follows:
- The virtual machines must achieve a cumulative uptime Service Level Agreement (SLA) of 99.99%99.99\%.
- The virtual machines must be protected against localized datacenter failures (such as power or cooling outages).
- Network latency between the virtual machines must be minimized to support real-time stream aggregation.

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

  1. Deploy the virtual machines across at least two Availability Zones in the Azure region.Cevap
  2. Associate the virtual machines with a Proximity Placement Group.Cevap
  3. C
    Deploy the virtual machines within an Availability Set.
  4. D
    Deploy all virtual machines within a single Availability Zone.

Cevap

Deploy the virtual machines across at least two Availability Zones in the Azure region and associate them with a Proximity Placement Group.
To satisfy the 99.99%99.99\% uptime SLA and zone-level fault tolerance, VMs must be distributed across two or more Availability Zones in the region. To satisfy the low-latency stream aggregation requirement, the VMs should be placed within a Proximity Placement Group, which physically groups resources together in the Azure infrastructure.

Adım Adım Çözüm

1
Analyze the SLA and high availability requirement.
To achieve a 99.99%99.99\% uptime SLA for Azure Virtual Machines, the instances must be deployed across at least two Availability Zones in the same region.
Deploying instances across zones protects the application from zone-wide physical failures (like power, cooling, or network events).
2
Analyze the network latency requirement.
Use a Proximity Placement Group (PPG) to group the virtual machines.
A Proximity Placement Group ensures that the VMs are physically colocated within the datacenters to minimize network latency.
