Docker Certified Associate (DCA) — Question 9

Seven managers are in a swarm cluster.
Is this how should they be distributed across three datacenters or availability zones?
5-1-1

Answer options

• A. Yes
• B. No

Correct answer: B

Explanation

The distribution of 5-1-1 is not ideal because it creates a single point of failure in the datacenter with one manager, which could lead to issues if that datacenter goes down. A better distribution would ensure that managers are more evenly spread to maintain quorum and high availability.
