Your SRE team wants to implement Chaos Engineering to test the resilience of a microservices application running on GKE. Which THREE actions represent valid chaos engineering experiments in GCP? (Select THREE)

Answer options:

Randomly terminating GKE pods

Simulating a zone failure by draining all nodes in a specific zone

Injecting artificial network latency between microservices

Deleting the production Cloud SQL database without a backup

Disabling billing for the GCP project

Running a load test to see maximum throughput

How to approach this question

Identify controlled failure injections that test system resilience.

Full Answer

Chaos Engineering involves injecting controlled failures to verify that the system's self-healing mechanisms work. Terminating pods, simulating zone outages, and injecting latency are standard practices (often done using tools like Istio fault injection). Destructive actions without recovery paths are not chaos engineering.

Common mistakes

Confusing load testing (F) with chaos engineering.
