The Complete Practical Docker Guide - Inspecting Default Bridge Network

The video tutorial explains how to manage Docker networks, including listing existing networks, inspecting the default bridge network, and understanding IP address assignment. It also introduces the process of creating custom networks using Docker commands.

What command is used to list all existing Docker networks?

• docker network display

• docker network show

• docker network list

• docker network ls

Which of the following is NOT a default Docker network?

• custom

• bridge

• host

• none

What is the default subnet for the bridge network in Docker?

• 192.168.0.0/16

• 172.17.0.0/16

• 10.0.0.0/8

• 192.168.1.0/24

How does Docker assign IP addresses to new containers in the bridge network?

• Manually by the user

• Based on the container name

• Sequentially from the network range

• Randomly from the available pool

Why must MAC addresses be unique within the same Docker network?

• To avoid data packet collisions

• To maintain network performance

• To ensure network security

• To prevent IP address conflicts
