Kubernetes and Cloud Native Associate (KCNA) — Question 154

What is the minimum of etcd members that are required for a highly available Kubernetes cluster?

Answer options

• A. Two etcd members.
• B. Five etcd members.
• C. Six etcd members.
• D. Three etcd members

Correct answer: D

Explanation

A minimum of three etcd members is required for a highly available Kubernetes cluster to ensure that it can tolerate failures and maintain quorum. Having two or fewer members would not provide the necessary redundancy, while five or six members is more than the minimum needed, which may not be efficient in terms of resources.
