Docker Certified Associate Certification Training Course - Container Network Model

The video tutorial explains the concept of container networks in Docker, focusing on the Container Network Model (CNM). It covers the roles of IPAM and network driver APIs, which manage address pools and network configurations. The CNM consists of three main components: network, endpoint, and sandbox. Networks allow communication between containers, endpoints connect sandboxes to networks, and sandboxes provide isolated environments for network configurations. The tutorial also highlights the implementation of these components using Linux Bridge and virtual Ethernet pairs.

What is the primary purpose of networks in a containerized business application?

• To enhance application performance

• To manage user access

• To facilitate communication between containers

• To store data securely

What does the IPAM driver API manage in the Container Network Model?

• Network security

• Address pools and container IP addresses

• User authentication

• Data encryption

Which component of the Container Network Model is responsible for creating or deleting networks?

• IPAM driver

• Endpoint

• Network driver

• Sandbox

What is the role of a sandbox in the Container Network Model?

• To manage user sessions

• To store application data

• To enhance network speed

• To provide an isolated environment for network configuration

How is an endpoint typically implemented in the Container Network Model?

• With a fiber optic cable

• With a physical Ethernet cable

• With a virtual Ethernet pair

• With a wireless connection
