2V0-71.23 Question 123
Single answerA development team is deploying a Kubernetes cluster using VMware Tanzu, and they need to configure a container network interface (CNI) that supports multiple network interfaces for their pods to enable advanced networking use cases, such as connecting to different VLANs or external networks. Which of the following statements best describes the role of the Multus CNI in this scenario?
- A
Multus CNI provides the ability to configure multiple network interfaces for pods in Kubernetes, enabling advanced networking scenarios.
- B
Multus CNI replaces the primary CNI plugin in Kubernetes to provide default networking for pods.
- C
Multus CNI is responsible for encrypting all network traffic within the Kubernetes cluster.
- D
Multus CNI is a standalone networking solution that does not integrate with other CNI plugins.
Show answer and explanation
Correct answer: A
Explanation
Multus CNI is a meta-plugin that enables Kubernetes pods to use multiple network interfaces by chaining multiple CNI plugins. This functionality is particularly useful for advanced networking scenarios, such as connecting to different VLANs, external networks, or SDN solutions. It does not replace the primary CNI plugin or provide standalone networking, but instead works in conjunction with other plugins for extended capabilities.
- A. Correct.
Correct: Multus CNI acts as a meta-plugin in Kubernetes, allowing pods to attach to multiple network interfaces while leveraging other CNI plugins for specific networking implementations.
- B. Incorrect.
Incorrect: Multus does not replace the primary CNI plugin but works alongside it to provide additional networking capabilities.
- C. Incorrect.
Incorrect: Multus CNI does not handle encryption of network traffic. Encryption in Kubernetes is typically handled by other tools or plugins like IPsec or WireGuard.
- D. Incorrect.
Incorrect: Multus is designed to work as a meta-plugin that integrates with other CNI plugins, rather than functioning as a standalone networking solution.
