Difficulty: EasyConfigure Public and Private IP Addresses

You are deploying a Standard Load Balancer in Azure to distribute traffic across a set of virtual machines. You need to configure a new Public IP address for the front-end IP configuration of this Load Balancer. Which combination of SKU and allocation method must you select for the Public IP address?

  1. A
    Basic SKU and Dynamic allocation
  2. B
    Standard SKU and Dynamic allocation
  3. Standard SKU and Static allocationAnswer
  4. D
    Basic SKU and Static allocation

Answer

Standard SKU and Static allocation
A Standard Load Balancer requires a Standard SKU Public IP address for its front-end configuration. Standard SKU Public IP addresses only support the Static allocation method. Therefore, selecting the Standard SKU and Static allocation method is the only correct configuration.

Step-by-Step Solution

1
Determine the SKU requirement of the Load Balancer.
Since a Standard Load Balancer is being deployed, the associated front-end Public IP address must also use the Standard SKU to avoid SKU mismatch.
Azure enforces SKU alignment between load balancers and their associated public IP addresses.
2
Determine the supported IP allocation method for the Standard SKU Public IP.
Standard SKU Public IP addresses support only the Static allocation method.
Dynamic allocation is not supported for Standard SKU Public IP addresses in Azure.
