2V0-71.23 Question 104
Select 3An organization is deploying a Tanzu Kubernetes Grid (TKG) cluster to host production workloads. They need to configure an ingress controller to handle incoming HTTP and HTTPS traffic for their applications. They decide to use Contour as the ingress controller. Which of the following statements accurately describe the role and functionality of the Contour ingress controller in this scenario?
- A
Contour provides Layer 7 load balancing and is used to manage HTTP/HTTPS traffic routing.
- B
Contour directly modifies Kubernetes Services to route traffic to Pods.
- C
Contour relies on Envoy as its data plane to process and route traffic.
- D
Contour supports advanced features like path-based routing and TLS termination for ingress.
- E
Contour replaces the need for a Kubernetes Service of type LoadBalancer.
Show answer and explanation
Correct answers: A, C, D
Explanation
Contour is a Kubernetes-native ingress controller that provides Layer 7 load balancing capabilities for HTTP and HTTPS traffic. It works in conjunction with Envoy as the data plane, enabling features like path-based routing, TLS termination, and virtual hosting. While it does not directly modify Kubernetes Services or replace a LoadBalancer service, it integrates with these to enable smooth traffic management. Understanding Contour's role and capabilities is crucial for deploying and managing ingress in a Tanzu Kubernetes Grid environment.
- A. Correct.
Correct. Contour is a Kubernetes ingress controller that provides Layer 7 load balancing and is specifically designed to manage HTTP/HTTPS traffic routing.
- B. Incorrect.
Incorrect. Contour does not directly modify Kubernetes Services. Instead, it works alongside Envoy to manage traffic routing based on ingress resources.
- C. Correct.
Correct. Contour leverages Envoy as its data plane, which processes and routes traffic based on the configuration provided by Contour.
- D. Correct.
Correct. Contour supports advanced ingress features such as path-based routing, TLS termination, and hostname-based virtual hosting.
- E. Incorrect.
Incorrect. Contour does not replace a Kubernetes Service of type LoadBalancer. It works with a LoadBalancer service to expose Envoy to external traffic.
