Difficulty: HardConfigure Public and Private IP Addresses

You are managing an Azure environment in the East US region. You have an Azure Virtual Machine named VM-Mgmt that has a single network interface named nic-mgmt. Currently, nic-mgmt has a primary IP configuration named ipconfig1, which is a member of the backend pool of a Standard SKU public load balancer named LB-Prod. To facilitate direct administration, you need to assign a new public IP address named PIP-Mgmt directly to ipconfig1. All resources are located in the East US region. Which SKU and allocation method must you configure for PIP-Mgmt?

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

Answer

Standard SKU and Static allocation
The correct configuration is Standard SKU and Static allocation. When a virtual machine's network interface is associated with the backend pool of a Standard SKU load balancer, any public IP address directly assigned to that network interface must also be a Standard SKU public IP to maintain SKU compatibility. Furthermore, Standard SKU public IP addresses in Azure only support Static allocation.

Step-by-Step Solution

1
Identify the SKU of the load balancer associated with the virtual machine's network interface.
The load balancer (LB-Prod) is a Standard SKU load balancer.
Azure requires SKU matching between a load balancer and any public IP addresses associated with resources in its backend pool.
2
Determine the required SKU for the public IP address (PIP-Mgmt).
PIP-Mgmt must be configured with the Standard SKU.
Associating a Basic SKU public IP with a network interface in a Standard Load Balancer backend pool is not supported.
3
Determine the allocation method for the Standard SKU public IP address.
The allocation method must be set to Static.
Standard SKU public IP addresses in Azure only support Static IP address allocation.
