Docker Certified Associate Certification Training Course - Docker Swarm Architecture

The video tutorial explains the architecture of Docker Swarm, focusing on its main components: the Swarm manager, worker nodes, and the Docker client. It details the roles of these components, including the manager's responsibility for maintaining cluster state and task scheduling, and the worker nodes' role in executing tasks. The tutorial also covers the master node's use of raft implementation for consistency and the types of service deployments: replicated and global.

What is the primary role of the Discovery Service in a Docker Swarm manager?

• To schedule services

• To manage the Docker client

• To identify and ensure worker nodes are running properly

• To run containers on worker nodes

Which component is responsible for maintaining the cluster state in Docker Swarm?

• Discovery Service

• Manager node

• Docker client

• Worker node

What is the role of the master node in a Docker Swarm with multiple managers?

• To ensure a consistent internal state across manager nodes

• To deploy services

• To run containers

• To manage worker nodes

In a replicated service deployment, what do you specify?

• The number of identical tasks

• The number of nodes

• The type of network

• The version of Docker

How does a global service deployment differ from a replicated one?

• It runs a single task on every node

• It runs multiple tasks on a single node

• It requires more resources

• It is only for manager nodes
