Difficulty: Very hardConfigure Public and Private IP Addresses

An administrator is configuring a secondary IP configuration for an Azure virtual machine named VM-Db1. VM-Db1 has a single network interface named nic-db1. VM-Db1 is currently part of the backend pool of a Standard Load Balancer named LB-Prod. The administrator needs to configure a new IP configuration named ipconfig2 on nic-db1 to meet the following requirements:

- The private IP address of ipconfig2 must be set to 10.10.1.5010.10.1.50.
- The public IP address of ipconfig2 must be accessible from the internet.
- VM-Db1 must remain in the backend pool of LB-Prod.

Which configuration must the administrator apply to ipconfig2 and the associated public IP address?

  1. Set the private IP allocation of ipconfig2 to Static, and associate a Standard SKU public IP address with Static allocation.Answer
  2. B
    Set the private IP allocation of ipconfig2 to Static, and associate a Basic SKU public IP address with Dynamic allocation.
  3. C
    Set the private IP allocation of ipconfig2 to Dynamic, and associate a Standard SKU public IP address with Static allocation.
  4. D
    Set the private IP allocation of ipconfig2 to Dynamic, and associate a Basic SKU public IP address with Static allocation.

Answer

Set the private IP allocation of ipconfig2 to Static, and associate a Standard SKU public IP address with Static allocation.
To satisfy the requirements, the private IP allocation must be set to Static to guarantee the assignment of 10.10.1.5010.10.1.50. Furthermore, because the virtual machine is in the backend pool of a Standard Load Balancer, any public IP address associated with the network interface must be of the Standard SKU. Standard SKU public IP addresses require Static allocation.

Step-by-Step Solution

1
Determine the required private IP allocation method.
Static allocation is required.
The requirement specifies a specific private IP address (10.10.1.5010.10.1.50). To ensure this exact address is assigned and does not change, Static allocation must be selected instead of Dynamic.
2
Determine the required SKU for the public IP address based on load balancer integration.
Standard SKU public IP is required.
VM-Db1 is a member of the backend pool of a Standard Load Balancer. Azure rules dictate that any public IP addresses associated with the network interfaces of VMs in a Standard Load Balancer backend pool must be Standard SKU. Basic SKU public IPs are incompatible in this scenario.
3
Determine the allocation method for the Standard SKU public IP address.
Static allocation is required.
Standard SKU public IP addresses in Azure are allocated statically to ensure the IP remains consistent and matches the lifecycle requirements of standard tier resources.
