Your SRE team wants to implement Chaos Engineering to test the resilience of a microservices architecture running on GKE. Which TWO practices align with Chaos Engineering principles? (Select TWO)
Answer options:
A.
Running load tests in a staging environment before a major release.
B.
Randomly terminating pods during business hours to verify self-healing.
C.
Injecting artificial latency into network calls between microservices.
D.
Performing a scheduled disaster recovery failover to a secondary region on a weekend.
E.
Reviewing application code for potential null pointer exceptions.
How to approach this question
Identify practices that involve intentionally injecting failures or degradation into a live system to test resilience.
Full Answer
Randomly terminating pods during business hours to verify self-healing., Injecting artificial latency into network calls between microservices.
Chaos Engineering is the discipline of experimenting on a system in order to build confidence in its capability to withstand turbulent conditions in production. Randomly terminating instances (pods) and injecting network latency are core techniques to validate that self-healing, retries, and circuit breakers work correctly.
Common mistakes
Selecting standard testing practices (A, D) instead of intentional failure injection.
