Difficulty: MediumConfigure Azure Load Balancer

You have a public load balancer named LB1 that uses the Basic SKU. LB1 distributes traffic to virtual machines in an Availability Set. You need to upgrade the load balancer to the Standard SKU to support Availability Zones. Which change must you make to the existing configuration before you can associate the backend virtual machines with the upgraded Standard SKU load balancer?

  1. A
    Configure the frontend public IP address to use dynamic IP allocation.
  2. B
    Associate a Basic SKU public IP address with the network interface of each virtual machine.
  3. Upgrade or replace the frontend public IP address with a Standard SKU public IP address.Answer
  4. D
    Disable the health probe of the load balancer during the upgrade.

Answer

Upgrade or replace the frontend public IP address with a Standard SKU public IP address.
A Standard SKU load balancer requires a Standard SKU public IP address for its frontend IP configuration. Basic SKU public IP addresses are not compatible with Standard SKU load balancers.

Step-by-Step Solution

1
Identify that a Standard SKU Load Balancer requires Standard SKU resources for its frontend and backend configurations.
Basic SKU frontend public IPs cannot be bound to Standard SKU Load Balancers.
Azure enforces SKU matching between the Load Balancer and its frontend public IP configuration.
2
Select the correct migration path for the frontend IP resource.
Upgrade the existing public IP SKU or provision a new Standard SKU public IP.
This satisfies the frontend SKU requirement of the Standard SKU Load Balancer.
