You are implementing chaos engineering to test the resilience of a microservices application running on GKE. You want to simulate network latency and HTTP 500 errors between services without modifying the application code. Which TWO technologies should you use? (Select TWO)

Anthos Service Mesh (based on Istio) deploys a sidecar proxy alongside every microservice. Because all traffic flows through these proxies, you can use the mesh's control plane to apply Fault Injection policies. You can configure the proxies to artificially introduce delays (latency) or abort requests (HTTP 500 errors) to test how resilient your application is to downstream failures, all without touching the application code.
