You are migrating a monolithic application to a microservices architecture on Kubernetes. You choose to use Istio to manage the communication between these new services. Which of the following is NOT a benefit of adopting Istio in this scenario?

A. Istio's control plane simplifies the deployment and management of microservices
B. Istio provides a consistent way to handle network calls and security across all microservices
C. Istio allows for easier debugging and troubleshooting of complex microservice interactions
D. Istio simplifies the process of migrating existing code to a microservices architecture
E. Istio helps in achieving better scalability and fault tolerance for microservices

Answer: D

Explanation:
While Istio provides benefits like centralized traffic management, security, and observability for microservices, it doesn't automatically simplify the process of migrating existing monolithic code. The migration itself requires careful refactoring and architectural changes, which Istio complements but doesn't replace. Options B, C, D, and E are all valid benefits of using Istio for microservices.

A. Node affinity
B. Self-healing
C. Pod Disruption Budgets
D. Rolling updates
E. Horizontal Pod Autoscaling

Answer: B

What is the primary benefit of using a GitOps approach to manage this deployment compared to traditional methods?

A. GitOps provides faster deployment times by eliminating the need for manual interventions.
B. GitOps simplifies the process of managing complex Kubernetes deployments by providing a centralized repository for configuration.
C. GitOps enhances security by preventing unauthorized changes to the Kubernetes cluster.
D. GitOps automates the deployment process, eliminating the need for human intervention.
E. GitOps enables easy rollbacks to previous deployments by leveraging the versioning capabilities of Git.

Answer: E
