Kubernetes and Cloud Native Associate (KCNA) — Question 27

What are the most important resources to guarantee the performance of an etcd cluster?

Answer options

• A. CPU and disk capacity.
• B. Network throughput and disk I/O.
• C. CPU and RAM memory.
• D. Network throughput and CPU.

Correct answer: B

Explanation

The correct answer is B because network throughput and disk I/O are essential for the fast operation of an etcd cluster, enabling efficient communication and data storage. Options A, C, and D, while important, do not prioritize the necessary network performance and disk operations required for optimal etcd functionality.
