2V0-71.23 Question 120
Single answerAn organization is deploying a Kubernetes cluster managed by VMware Tanzu and requires multiple network interfaces for their pods to support advanced networking use cases such as separating traffic types and integrating with external systems. How does Multus CNI help in meeting this requirement?
- A
Multus CNI allows pods to attach to multiple network interfaces, enabling advanced networking features.
- B
Multus CNI replaces the default Kubernetes CNI plugin to provide a single, specialized network interface.
- C
Multus CNI integrates with VMware NSX-T to provide built-in Layer 3 networking capabilities.
- D
Multus CNI ensures that all pods in a cluster share the same network interface for simplified configuration.
Show answer and explanation
Correct answer: A
Explanation
Multus CNI is a Container Network Interface plugin for Kubernetes that allows pods to attach to multiple network interfaces. This capability is particularly useful in scenarios requiring advanced networking configurations, such as separating traffic types (e.g., data plane and management plane) or integrating with external networking systems. It works alongside the default CNI plugin and does not replace it, making it a versatile tool for complex networking requirements in Kubernetes clusters.
- A. Correct.
Correct: Multus CNI allows pods to attach to multiple network interfaces, which is beneficial for advanced use cases such as separating different traffic types or integrating with external systems.
- B. Incorrect.
Incorrect: Multus CNI does not replace the default Kubernetes CNI plugin. Instead, it works alongside it to allow multiple network interfaces per pod.
- C. Incorrect.
Incorrect: While Multus CNI can integrate with other CNIs like NSX-T, its primary role is not to provide built-in Layer 3 networking but to enable multiple interfaces.
- D. Incorrect.
Incorrect: Multus CNI is designed to provide flexibility by allowing multiple interfaces, not to enforce a single shared network interface.
