2V0-71.23 Question 36
Select 3A company is deploying VMware Tanzu Service Mesh to manage microservices communication in its Kubernetes clusters. The team wants to ensure secure communication between services, gain visibility into service-to-service traffic, and implement traffic management policies. Which features of a service mesh directly address these requirements?
- A
Mutual TLS (mTLS) for encrypted communication between services
- B
Service discovery using Kubernetes DNS
- C
Traffic shaping and routing policies for managing service traffic
- D
Centralized logging and monitoring for Kubernetes nodes
- E
Observability with metrics, tracing, and logs for service-to-service communication
Show answer and explanation
Correct answers: A, C, E
Explanation
A service mesh like VMware Tanzu Service Mesh provides critical features such as secure communication (mTLS), traffic management (routing policies), and observability (metrics, tracing, and logs). These capabilities directly address the requirements of securing service communication, managing traffic, and gaining visibility into service-to-service interactions. Other features like service discovery and node monitoring are outside the scope of a service mesh.
- A. Correct.
Mutual TLS (mTLS) is a key feature of a service mesh that ensures secure communication between services by encrypting traffic and authenticating service identities.
- B. Incorrect.
Service discovery using Kubernetes DNS is a basic Kubernetes feature and not specifically provided by a service mesh.
- C. Correct.
Traffic shaping and routing policies are core functionalities of a service mesh, allowing for advanced traffic management such as canary deployments and failover strategies.
- D. Incorrect.
Centralized logging and monitoring for Kubernetes nodes is not a service mesh feature but relates to Kubernetes infrastructure monitoring.
- E. Correct.
Observability with metrics, tracing, and logs for service-to-service communication is a fundamental feature of a service mesh, providing insights into application performance and behavior.
