2V0-71.23 Question 122
Single answerYou are tasked with deploying a Kubernetes cluster using VMware Tanzu, and the application requirements state that certain pods need to have multiple network interfaces for separate network traffic (e.g., one for management traffic and another for application traffic). Which of the following describes a key role of Multus Container Network Interface (CNI) in meeting this requirement?
- A
Multus CNI enables pods to have multiple network interfaces attached to them, allowing traffic segregation for different use cases.
- B
Multus CNI replaces the default network plugin in Kubernetes with a custom dual-network configuration.
- C
Multus CNI integrates with Kubernetes to dynamically adjust pod resources like CPU and memory based on network traffic.
- D
Multus CNI provides a single, unified network interface for all pods in the cluster.
Show answer and explanation
Correct answer: A
Explanation
Multus is a Container Network Interface (CNI) plugin that enables attaching multiple network interfaces to a Kubernetes pod. This functionality is critical for use cases requiring traffic isolation or connections to multiple networks. Unlike standard CNI plugins that provide a single network interface, Multus works alongside the primary CNI plugin to configure additional interfaces without replacing the primary configuration.
- A. Correct.
Correct. Multus CNI allows Kubernetes pods to have multiple network interfaces, enabling features like traffic segregation for different purposes such as management and application traffic.
- B. Incorrect.
Incorrect. Multus CNI does not replace the default plugin; instead, it works alongside the primary CNI plugin to provide additional interfaces.
- C. Incorrect.
Incorrect. Multus CNI is solely focused on networking and does not manage pod resources such as CPU or memory.
- D. Incorrect.
Incorrect. Multus CNI does the opposite of providing a single network interface, it enables multiple interfaces to meet advanced networking requirements.
