Kubernetes and Cloud Native Associate (KCNA) — Question 58

What is the main role of the Kubernetes DNS within a cluster?

Answer options

• A. Acts as a DNS server for virtual machines that are running outside the cluster.
• B. Provides a DNS as a Service, allowing users to create zones and registries for domains that they own.
• C. Allows Pods running in dual stack to convert IPv6 calls into IPv4 calls.
• D. Provides consistent DNS Names for Pods and Services for workloads that need to communicate with each other.

Correct answer: D

Explanation

The correct answer is D because Kubernetes DNS is designed to provide consistent DNS naming for Pods and Services, facilitating communication between them within the cluster. Options A and B are incorrect as they refer to external DNS functionalities that are not part of the Kubernetes DNS role, while option C inaccurately describes a feature not specifically related to the primary purpose of Kubernetes DNS.
