medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate packets per backend before failure
600 packets / 3 backends = 200 packets per backend.Step 2: Recalculate after one backend fails
Remaining 2 backends share 600 packets evenly: 600 / 2 = 300 packets per backend.Final Answer:
300 packets per second -> Option AQuick Check:
Packets per backend after failure = Total packets / Remaining backends [OK]
Quick Trick: Recalculate load dividing by active backends only [OK]
Common Mistakes:
- Not adjusting for failed backend
- Assuming load stays same per backend
- Ignoring backend health status
