Zorluk: OrtaConfigure VMs for High Availability

Solas Health plans to deploy a new web application in the UK South region. The deployment will include two virtual machines named VM-Web1 and VM-Web2. The solution must guarantee a 99.99% SLA for virtual machine availability and protect the application against datacenter-wide outages within the region. Which two actions should you perform? (Select two.)

  1. Deploy VM-Web1 in Zone 1 and VM-Web2 in Zone 2Cevap
  2. B
    Deploy VM-Web1 and VM-Web2 in a new Availability Set
  3. Associate the virtual machines with a Standard SKU Load BalancerCevap
  4. D
    Associate the virtual machines with a Basic SKU Load Balancer

Cevap

To meet the requirements, you must deploy VM-Web1 in Zone 1 and VM-Web2 in Zone 2, and associate the virtual machines with a Standard SKU Load Balancer.
Deploying the virtual machines in separate Availability Zones guarantees protection against datacenter-wide failures and meets the 99.99% uptime SLA requirement. To load balance traffic across different zones, a Standard SKU Load Balancer must be used because it supports zone-redundant configurations.

Adım Adım Çözüm

1
Evaluate the SLA and redundancy requirements.
Determined that a 99.99% VM uptime SLA and defense against datacenter-wide failures require the use of Availability Zones rather than Availability Sets (which only offer a 99.95% SLA).
Availability Zones host resources in separate physical locations within a region, providing higher SLA and protection against single-datacenter disasters.
2
Select the target placement for VM-Web1 and VM-Web2.
Deployed VM-Web1 in Zone 1 and VM-Web2 in Zone 2.
Distributing the virtual machines across two distinct zones provides physical isolation for the instances.
3
Select the load balancer tier required for zone-spanning backend pools.
Configured a Standard SKU Load Balancer to route traffic to the backend virtual machines.
Only Standard SKU Load Balancers support zone-redundant backend pools and zone-specific VM distributions, whereas Basic SKU Load Balancers do not.

Anahtar Kavram

Configuring virtual machines across Availability Zones and pairing them with Standard Load Balancers to achieve maximum high availability and datacenter-level fault tolerance.
