Zorluk: KolayConfigure VMs for High Availability

CloudSpire Solutions plans to deploy three virtual machines named VM-Auth1, VM-Auth2, and VM-Auth3 in the UK South region. The company has a deployment constraint requiring protection against a complete datacenter outage in the region. Which configuration should you use?

  1. Deploy the virtual machines across multiple Availability ZonesCevap
  2. B
    Deploy the virtual machines in a single Availability Set
  3. C
    Deploy the virtual machines in a Proximity Placement Group
  4. D
    Deploy the virtual machines to different Resource Groups

Cevap

Deploy the virtual machines across multiple Availability Zones
Deploying the virtual machines across multiple Availability Zones locates each VM in a physically separate datacenter with independent power, cooling, and network infrastructure. This design protects the application from datacenter-wide outages within the region.

Adım Adım Çözüm

1
Analyze the high availability requirement
The requirement specifies protection against a complete datacenter-wide failure (power or cooling outage) in the region.
Identifying the failure domain scale (datacenter-level vs. rack-level) is necessary to choose between Availability Sets and Availability Zones.
2
Evaluate Availability Zones against the requirement
Availability Zones locate VMs in physically separate datacenters with independent power, cooling, and networking within the region.
This physical separation directly satisfies the requirement to survive a datacenter-wide outage.
3
Evaluate the distractors
Availability Sets protect only against rack-level (fault domain) or host-level (update domain) failures within one datacenter. Proximity Placement Groups group VMs close together, increasing risk. Resource groups are logical boundaries.
Confirming why alternative configurations do not meet the datacenter-wide outage requirement ensures the selection is correct.

Anahtar Kavram

Availability Zones provide physical isolation and redundancy by deploying resources across separate datacenters within a region, protecting against datacenter-wide failures.
