Zorluk: KolayApplication Load Balancing and Delivery

An enterprise is modernizing a regional database application that uses TCP port 1433 for replication. The application is hosted on a pool of Azure Virtual Machines within a single region. The design requires a regional load balancer to distribute the TCP traffic without needing SSL/TLS termination or application-layer (HTTP/HTTPS) routing. You plan to deploy an Azure Standard Load Balancer.

Which two configurations are required to ensure the virtual machines can be successfully associated with the backend pool of the Standard Load Balancer? (Choose two.)

  1. Deploy the virtual machines using Standard SKU public IP addresses if public IPs are assigned.Cevap
  2. Configure the virtual machines within the same virtual network as the Standard Load Balancer.Cevap
  3. C
    Deploy the virtual machines using Basic SKU public IP addresses.
  4. D
    Deploy a Basic Load Balancer to manage the backend pool of the virtual machines.

Cevap

To associate virtual machines with the backend pool of an Azure Standard Load Balancer, the virtual machines must be configured to use Standard SKU public IP addresses (if public IPs are assigned) and must be located in the same virtual network as the Standard Load Balancer.
The correct configurations are deploying the virtual machines using Standard SKU public IP addresses and placing the virtual machines in the same virtual network as the load balancer. The Azure Standard Load Balancer has strict SKU matching rules: any public IP addresses assigned to the backend virtual machines must be of the Standard SKU. In addition, the virtual machines must exist in the same virtual network as the load balancer.

Adım Adım Çözüm

1
Determine the load balancing layer and SKU requirement.
The scenario specifies a regional TCP application utilizing an Azure Standard Load Balancer.
This establishes that the backend pool configuration must adhere to the Standard Load Balancer's requirements.
2
Evaluate the IP configuration requirements for the backend pool.
Virtual machines connected to the Standard Load Balancer's backend pool must not use Basic SKU public IP addresses.
Azure enforces SKU matching, meaning Standard Load Balancers require Standard SKU public IPs for any backend virtual machines that possess public IPs.
3
Determine the network boundary requirements.
The virtual machines and the Standard Load Balancer must reside within the same virtual network boundary.
This is a network connectivity prerequisite for the backend pool of an Azure Standard Load Balancer.
