Zorluk: ZorConfigure Azure Load Balancer

An administrator is configuring a public load balancer to distribute traffic to three virtual machines:

* VM1 and VM2, which are in an Availability Set named AS1
* VM3, which is a standalone virtual machine

All virtual machines are located in the same virtual network and subnet.

The administrator has created a Standard SKU public IP address named Pub-IP1 and a Basic SKU load balancer named LB1.

You need to identify the configuration changes required to load balance incoming internet traffic across VM1, VM2, and VM3 using Pub-IP1.

Which two actions should you perform? (Choose two.)

  1. Deploy a Standard SKU load balancer.Cevap
  2. Associate Pub-IP1 with the frontend IP configuration of the Standard SKU load balancer.Cevap
  3. C
    Associate Pub-IP1 with the frontend IP configuration of the existing Basic SKU load balancer (LB1).
  4. D
    Configure the backend pool of the existing Basic SKU load balancer (LB1) to include both the virtual machines in AS1 and the standalone virtual machine VM3.

Cevap

Deploy a Standard SKU load balancer, and associate Pub-IP1 with the frontend IP configuration of the Standard SKU load balancer.
To support load balancing across a mixed pool of standalone virtual machines and virtual machines in an availability set, and to utilize a Standard SKU public IP address, a Standard SKU load balancer is required. The Standard SKU public IP address must then be associated with the frontend IP configuration of this Standard SKU load balancer.

Adım Adım Çözüm

1
Analyze the SKU compatibility of the public IP address and the load balancer.
Identify that the public IP (Pub-IP1) is Standard SKU, while the existing load balancer (LB1) is Basic SKU. These SKUs are incompatible.
Azure requires the Public IP SKU to match the Load Balancer SKU.
2
Analyze the backend pool requirements for the virtual machines.
Identify that the virtual machines are a mix of an availability set (AS1) and a standalone VM (VM3). A Basic SKU load balancer cannot support this configuration in its backend pool.
Basic SKU load balancers only support virtual machines within a single availability set or virtual machine scale set in their backend pool.
3
Determine the required load balancer SKU to support both the Standard public IP and the mixed backend pool configuration.
Determine that a Standard SKU load balancer must be deployed.
Standard SKU load balancers support Standard public IPs and allow any virtual machines in a single virtual network to be added to the backend pool.
4
Determine the frontend IP configuration action.
Associate Pub-IP1 with the frontend IP configuration of the Standard SKU load balancer.
This binds the incoming public traffic destination to the new Standard SKU load balancer.
