In the context of Docker, what does CNM support?

In the context of Docker, the correct answer relates to the concept of CNM, which stands for Container Networking Model. CNM is designed to facilitate the networking capabilities of containers, ensuring that applications can be deployed in a consistent manner across various computing environments. This allows for application portability, meaning that applications built in containers can be run seamlessly across different infrastructures, whether they are on-premises, in the cloud, or in hybrid setups.

The focus of CNM on networking capabilities enables developers to set up container networks that are adaptable and can communicate with each other efficiently, regardless of the underlying infrastructure's differences. This capability is fundamental to Docker's promise of creating lightweight, portable applications that can function uniformly across diverse platforms.

While the other options present different aspects of technology, they do not directly correlate with the primary function and benefit of CNM. For example, broad software compatibility can be achieved through other means and isn’t specific to networking in containers, enhanced virtual machine performance is unrelated to container networking, and static IP assignments are just one configuration option that doesn’t capture the full extent of what CNM supports in terms of application portability and networking.
