Docker Certified Associate (DCA) — Question 7

In the context of a swarm mode cluster, does this describe a node? an instance of the Docker CLI connected to the swarm

Answer options

• A. Yes
• B. No

Correct answer: B

Explanation

The correct answer is B because a node in a swarm mode cluster refers to an instance of Docker Engine that participates in the swarm, not the Docker CLI itself. The Docker CLI is merely a tool used to interact with the swarm, but it does not represent a node within the architecture.
