📝 **Question:** Redis is down. Which probe should fail? 📋 Pick the right answer. 💡 **Hint:** Re-read the theory above if unsure.
A
Liveness — let kubelet kill and restart every pod each Redis blip.
B
Readiness only — pod stays alive but LB drains traffic.
C
Both probes — fail liveness AND readiness simultaneously.
D
Neither — return 200 from both and surface the error in the response.
