Difficulty: MediumConfigure Public and Private IP Addresses

You are deploying an Azure Standard Load Balancer named LB1 to load balance traffic across three virtual machines. You need to create a new Public IP address named pip-web to use as the frontend IP configuration for LB1. Which two settings should you configure for pip-web?

  1. SKU: StandardAnswer
  2. Allocation: StaticAnswer
  3. C
    SKU: Basic
  4. D
    Allocation: Dynamic

Answer

The correct configurations are Standard for the SKU and Static for the allocation method.
To ensure compatibility, a Standard Load Balancer must use a Standard SKU Public IP address. Because Standard SKU Public IPs only support Static allocation, you must configure both Standard SKU and Static allocation.

Step-by-Step Solution

1
Determine the required SKU for the Public IP address based on the Load Balancer type.
Since the load balancer is a Standard Load Balancer, the associated Public IP address must also be a Standard SKU.
Azure requires SKU alignment between the Load Balancer and the Public IP used in its frontend IP configuration.
2
Identify the supported allocation method for the Standard SKU Public IP address.
Standard SKU Public IP addresses only support Static allocation.
Dynamic allocation is not available for Standard SKU Public IP addresses in Azure.

Key Concept

Configuring Public IP SKU and allocation methods for Azure Load Balancer frontend IP configurations.
