Zorluk: OrtaConfigure VMs for High Availability

Vanguard Systems is deploying a critical database workload in the East Asia region. You need to configure four virtual machines (VMs) to host the application. The deployment must meet the following requirements:
- Guarantee a virtual machine uptime SLA of 99.99%99.99\%.
- Protect the application from datacenter-wide power or cooling failures.
- Distribute incoming traffic across the virtual machines.

Which of the following actions should you perform to meet the requirements? (Select two.)

  1. Deploy the virtual machines across separate Availability Zones in the East Asia region.Cevap
  2. Associate the virtual machines with a Standard SKU Load Balancer.Cevap
  3. C
    Deploy the virtual machines in an Availability Set that spans across multiple Availability Zones.
  4. D
    Associate the virtual machines with a Basic SKU Load Balancer.

Cevap

To meet the requirements, you must deploy the virtual machines across separate Availability Zones to satisfy the SLA and protect against zone-level failures, and use a Standard SKU Load Balancer to distribute traffic across those zones.
Deploying the virtual machines across separate Availability Zones provides datacenter-level isolation, meeting the 99.99%99.99\% SLA and safeguarding against datacenter-wide power or cooling outages. Since the VMs are distributed across different zones, a Standard SKU Load Balancer is required to distribute incoming traffic, as the Basic SKU Load Balancer is restricted to a single Availability Set or zone.

Adım Adım Çözüm

1
Evaluate the SLA and power/cooling protection requirements.
Determine that Availability Zones are required instead of Availability Sets.
An uptime SLA of 99.99%99.99\% requires virtual machines to be spread across multiple Availability Zones. Availability Sets only provide up to 99.95%99.95\% SLA and do not protect against datacenter-wide failures.
2
Determine the load balancer SKU required for the zonal backend pool.
Identify that a Standard SKU Load Balancer must be used.
Only Standard Load Balancers support routing traffic to virtual machines deployed across multiple Availability Zones.

Anahtar Kavram

Deploying virtual machines across Availability Zones for high availability and distributing traffic using a Standard Load Balancer.
