NEW QUESTION # 26
Consider the following Istio configuration snippet:

What does this configuration achieve?

  • A. It enables Istio's 'fault injection' feature to simulate failures and test the service's resilience.
  • B. It configures a virtual service that only routes traffic to the 'productcatalog-v2.example.com' service for requests that match the '/products' path
  • C. It exposes the 'productcatalog' service on port 80 using the 'istio-system/gateway' gateway and routes traffic to both 'productcatalog.example-com' and 'productcatalog-v2.example.com' with a 50/50 weight distributiom
  • D. It defines a virtual service named 'productcatalog' in the 'default' namespace and forwards all traffic to the 'productcatalog.example-com' service-
  • E. It creates a virtual service that routes all requests to the 'productcatalog.example-com' service only if they match the URI prefix '/products'

Answer: C

Explanation:
This Istio VirtualService configuration exposes the 'productcatalog' service on port 80 using the 'istio- system/gateway' gateway It routes traffic to both 'productcatalog.example.com' and 'productcatalog-v2.example.com' with a 50/50 weight distribution for requests matching the 'Iproducts' prefix. This configuration demonstrates Istio's ability to implement dynamic traffic routing and load balancing between services.


NEW QUESTION # 27
Consider the following Kubernetes YAML definition for a Deployment:

Which of the following statements about this Deployment are true?

  • A. The Deployment will create 3 Pods with the label 'app: nginx'.
  • B. The Deployment will expose the Pods on port 80.
  • C. The Deployment will only create Pods with the label 'app: nginx' if a corresponding Service exists.
  • D. The Deployment will create a Service that exposes the Pods on port 80.
  • E. The Deployment will use the 'nginx:l. 14.2' image to create the Pods.

Answer: A,E

Explanation:
The Deployment will create 3 Pods with the label 'app: nginx' because the 'selector' and 'template.metadata.labels' sections specify this. The Deployment will use the 'nginx:l. 14.2' image to create the Pods as defined in the 'spec.template.spec.containers' section. The Deployment itself does not create a Service. You would need to create a separate Service resource to expose the Pods on port 80.
