2V0-71.23 Question 224
Select 3You are designing a Kubernetes cluster using VMware Tanzu and need to choose an appropriate Container Network Interface (CNI) plugin. The application workloads running on this cluster include both traditional stateless services and modern microservices that require cross-pod communication and network policies for security. Which CNI plugin(s) would best suit this use case?
- A
Calico
- B
Flannel
- C
Antrea
- D
Weave Net
- E
NSX-T
Show answer and explanation
Correct answers: A, C, E
Explanation
When designing a Kubernetes cluster with workloads requiring cross-pod communication and security policies, it's essential to choose a CNI plugin that supports these features. Calico, Antrea, and NSX-T are all capable of providing advanced networking and security controls. Flannel and Weave Net, while simpler, do not offer the necessary features for this use case, such as robust network policy implementation.
- A. Correct.
Calico is a popular CNI plugin that supports advanced networking features such as network policies, security, and scalability, making it suitable for workloads requiring cross-pod communication and security controls.
- B. Incorrect.
Flannel is a simpler CNI plugin primarily designed for basic pod networking. It lacks advanced features such as network policies, which makes it less suitable for workloads requiring secure communication.
- C. Correct.
Antrea, built by VMware, offers advanced networking features, including network policies and integration with VMware ecosystems. It is well-suited for environments with modern microservices and security requirements.
- D. Incorrect.
Weave Net provides basic pod networking and simplicity but lacks robust network policy support, making it less ideal for scenarios requiring advanced security controls.
- E. Correct.
NSX-T is a VMware-native networking solution designed for enterprise-grade Kubernetes clusters. It supports advanced networking, security, and integration with Tanzu, making it suitable for workloads requiring secure cross-pod communication.
