Oracle Cloud Infrastructure 2020 Architect Associate — Question 2

In Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE), what does a Replica Set do?

Answer options

• A. It provides declarative updates for Pods.
• B. It maintains a stable set of replica Pods running at any given time.
• C. It ensures that all Nodes run a copy of a Pod.
• D. It exposes an application running on a set of Pods.

Correct answer: B

Explanation

The correct answer is B because a Replica Set ensures that a specified number of replica Pods are running, providing high availability and scalability. Option A refers to Deployments, which manage updates, while option C incorrectly suggests that it operates on Nodes instead of Pods. Option D describes the function of a Service, not a Replica Set.
