2V0-71.23 Question 76
Select 3Your organization is deploying a microservices-based application across multiple Kubernetes clusters. The application requires secure communication between services, the ability to monitor traffic between those services, and the ability to apply policies for traffic control. How does VMware Tanzu Service Mesh address these requirements?
- A
Tanzu Service Mesh provides end-to-end encryption for service-to-service communication.
- B
Tanzu Service Mesh automatically scales Kubernetes worker nodes based on service traffic.
- C
Tanzu Service Mesh supports observability by providing insights into service traffic and dependencies.
- D
Tanzu Service Mesh allows defining and enforcing fine-grained traffic control and security policies.
- E
Tanzu Service Mesh replaces Kubernetes NetworkPolicies for pod-to-pod communication.
Show answer and explanation
Correct answers: A, C, D
Explanation
VMware Tanzu Service Mesh is designed to address key challenges in microservices architectures by providing end-to-end encryption, observability, and fine-grained policy enforcement. These features ensure secure communication, traffic management, and visibility across multi-cluster environments. However, Tanzu Service Mesh does not handle cluster scaling or replace Kubernetes NetworkPolicies, as those responsibilities lie outside its scope.
- A. Correct.
Correct: Tanzu Service Mesh ensures secure communication between services by providing end-to-end encryption, often using mTLS (mutual TLS).
- B. Incorrect.
Incorrect: Tanzu Service Mesh does not manage Kubernetes worker node scaling. This functionality is handled by Kubernetes features like the Cluster Autoscaler.
- C. Correct.
Correct: Tanzu Service Mesh includes observability features that allow users to monitor traffic flows and service dependencies, which is essential for debugging and understanding microservices interactions.
- D. Correct.
Correct: Tanzu Service Mesh enables fine-grained control and enforcement of traffic policies, such as access control and traffic routing, ensuring compliance and security.
- E. Incorrect.
Incorrect: Tanzu Service Mesh complements Kubernetes NetworkPolicies but does not replace them. NetworkPolicies remain a core Kubernetes feature for controlling pod-to-pod communication.
