How can the organization fulfil the license requirement as the MAC address changes every time an instance is started/stopped/terminated?
It is not possible to have a fixed MAC address with AWS.
The organization should use VPC with the private subnet and configure the MAC address with that subnet.
The organization should use VPC with an elastic network interface which will have a fixed MAC Address.
The organization should use VPC since VPC allows to configure the MAC address for each EC2 instance.
Explanations:
While it’s true that MAC addresses for EC2 instances can change with instance lifecycle events, there are ways to retain a consistent MAC address within AWS.
A private subnet does not allow for configuration of MAC addresses for instances; it manages IP addressing, not MAC address persistence.
By using an Elastic Network Interface (ENI), the organization can attach a network interface with a fixed MAC address to the EC2 instance, fulfilling the licensing requirement.
VPC does not inherently allow users to configure MAC addresses directly for instances; it is the Elastic Network Interface that provides the capability to have a consistent MAC address.
I conclude that the answer is:
The organization should use VPC with an elastic network interface which will have a fixed MAC Address.
