This question evaluates your knowledge of Kubernetes Services — a core concept tested in cloud certification exams. Understanding Kubernetes Services is essential for designing scalable, secure, and cost-effective cloud architectures. Mastery of this topic will help you answer scenario-based questions confidently on exam day.
When defining a Kubernetes Service, which type ensures the service is exposed on each node’s IP at a static port?
Your organization wants to expose a web application running on Kubernetes to external traffic. You need a solution that assigns a static public IP address and routes traffic across all healthy nodes. Which Kubernetes Service type is most appropriate?
You are deploying a StatefulSet for a distributed database (Cassandra) that requires each pod to have a stable, resolvable network identity. Which Kubernetes Service configuration is required?
