Kubernetes and Cloud Native Associate (KCNA) — Question 112

The IPv4/IPv6 dual stack in Kubernetes:

Answer options

• A. Translates an IPv4 request from a service to an IPv6 service.
• B. Allows you to access the IPv4 address by using the IPv6 address.
• C. Requires NetworkPolicies to prevent services from mixing requests.
• D. Allows you to create IPv4 and IPv6 dual stack services.

Correct answer: D

Explanation

The correct answer is D because the dual stack feature in Kubernetes allows for the creation of services that can operate using both IPv4 and IPv6 addresses. Options A and B incorrectly describe the functionality, as there is no translation or access mechanism between the two protocols. Option C is not accurate since NetworkPolicies are not a requirement for dual stack operation.
