Docker Certified Associate Certification Training Course - Docker Architecture

The video tutorial explains Docker's architecture, focusing on its client-server model, including components like Docker client, host, images, containers, and registry. It details how the Docker client communicates with the daemon to execute commands, the role of Docker images as templates, and the encapsulated environment of containers. Networking options for containers are discussed, highlighting different network drivers. The tutorial also covers Docker's storage options, including volumes and plugins, and explains how Docker registry stores images, with commands like Docker pull, push, and run.

What is the primary role of the Docker client in the Docker architecture?

• To manage Docker networks

• To provide a user interface for Docker

• To execute Docker commands and communicate with the Docker daemon

• To store Docker images

Which of the following best describes a Docker image?

• A running instance of a Docker container

• A template used to create Docker containers

• A storage solution for Docker data

• A network configuration for Docker

What is the main difference between a private and a public Docker registry?

• Private registries are faster than public registries

• Private registries are used within an organization, while public registries are accessible to everyone

• Private registries store only Docker images, while public registries store all types of files

• Private registries are for individual use, while public registries are for organizations

Which network driver is the default for Docker containers?

• Macvlan

• Bridge

• Overlay

• Host

What is the purpose of the Macvlan network driver in Docker?

• To provide a MAC address to containers, making them appear as physical devices

• To connect containers on different Docker hosts

• To eliminate network barriers between containers and hosts

• To disable all networking options

Which storage option involves mounting a local directory of a host into a Docker container?

• Data volumes

• Volume container

• Directory mounts

• Storage plugins

What is the function of storage plugins in Docker?

• To manage Docker networks

• To create new Docker images

• To link Docker to external storage systems

• To store data within the container's writable layer
