2V0-71.23 Question 287
Select 4You are managing a Kubernetes environment on VMware Tanzu and need to ensure reliable application connectivity with advanced traffic control capabilities. The goal is to provide service discovery, load balancing, and traffic shaping for microservices-based applications. Which application connectivity services and traffic control benefits are MOST aligned with this requirement?
- A
Service Mesh for secure communication and traffic observability between microservices
- B
Ingress Controller for external traffic routing and load balancing
- C
DNS-based service discovery for locating services within the cluster
- D
Horizontal Pod Autoscaler for scaling pods based on resource usage
- E
Traffic Splitting for blue-green or canary deployments
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Application connectivity services and traffic control benefits in VMware Tanzu and Kubernetes environments include service discovery, secure communication, load balancing, and advanced traffic control mechanisms. Service Mesh, Ingress Controllers, DNS-based service discovery, and Traffic Splitting contribute directly to these capabilities. Horizontal Pod Autoscaler, while important for operational scaling, does not align with the specific requirements of application connectivity or traffic control in this scenario.
- A. Correct.
Service Mesh is critical for secure communication, observability, and advanced traffic control, such as retries or circuit breaking, between microservices. It directly supports reliable application connectivity.
- B. Correct.
Ingress Controller facilitates external traffic routing and load balancing, ensuring that external requests to applications are handled efficiently.
- C. Correct.
DNS-based service discovery is essential for identifying and connecting services within a Kubernetes cluster, supporting application connectivity.
- D. Incorrect.
Horizontal Pod Autoscaler is focused on resource-based scaling of pods rather than application connectivity or traffic control, making it irrelevant to the question's requirements.
- E. Correct.
Traffic Splitting is a key feature for advanced traffic control, enabling smooth deployments like blue-green or canary, which improves application reliability and connectivity.
