This page represents practice test consisting of objective questions and answers on Kubernetes. The practice test can prove to be very helpful if you are preparing to take Certified Kubernetes Administrator (CKA) certification examination in near future. It covers the Core Concepts from CKA certification exam syllabus.
Those preparing for interviews in relation with Kubernetes or cloud-native apps would find these questions to be useful enough. These questions can prove to be useful for interns / freshers / beginners.
These questions are related with some of the following topics:
- Kubernetes Pods
- New feature release in Kubernetes 1.8 such as taints and tolerations
The following is link to other practice tests:
- Practice test on introduction to Kubernetes
- Practice test on Pods, Container hooks
- Practice test on Pods Lifecycle
- Practice test on Services
Overview on Kubernetes Taints and Tolerations Concepts
Kubernetes 1.8 release came up with the feature taints and tolerations. The primary goal of this feature is to ensure that pods do not get scheduled to inappropriate nodes. Taints and applied to nodes and tolerations are applied to pods. Applying tolerations to pods would ensure that pods are scheduled on nodes with matching taints.
