Docker Certified Associate (DCA) — Question 55

Seven managers are in a swarm cluster.

Is this how should they be distributed across three datacenters or availability zones?

4-2-1

Answer options

• A. Yes
• B. No

Correct answer: B

Explanation

The distribution of 4-2-1 is not ideal as it creates a risk of losing a majority if the datacenter with four managers goes down. A more balanced distribution would be recommended to ensure high availability and fault tolerance across all zones.
