Zorluk: KolayConfigure VMs for High Availability

Lumina Financial plans to deploy two new virtual machines named VM-Finance1 and VM-Finance2 in the Australia East region. The company has a business requirement to ensure that the application remains available even if an entire physical datacenter facility within the region experiences a power or cooling failure. Which configuration should you use to deploy the virtual machines?

  1. Deploy the virtual machines across different Availability Zones in the region.Cevap
  2. B
    Deploy both virtual machines in a new Availability Set.
  3. C
    Deploy both virtual machines in a single Proximity Placement Group.
  4. D
    Deploy both virtual machines as standalone instances with Standard HDD storage.

Cevap

Deploy the virtual machines across different Availability Zones in the region.
Deploying the virtual machines across different Availability Zones in the region is correct because Availability Zones are physically separate datacenter facilities within an Azure region. Each zone has independent power, cooling, and networking, which ensures that if one datacenter goes down, the VM in the other zone remains available.

Adım Adım Çözüm

1
Analyze the high availability requirement.
The requirement specifies protection against the failure of an entire physical datacenter facility (power or cooling outage) in the Australia East region.
Understanding the failure boundary helps differentiate between rack-level redundancy and datacenter-level redundancy.
2
Compare Azure high availability options against the failure boundary.
Availability Sets protect against local hardware failures within a single datacenter. Availability Zones are physically separate datacenters in the same region, providing protection against datacenter-wide outages.
Evaluating the capabilities of each option ensures alignment with the business constraint.
3
Select the configuration that satisfies the requirement.
Deploying the virtual machines across different Availability Zones is the correct design choice.
This is the only option that isolates virtual machines across separate physical locations to survive facility-level failures.
