medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Understand concurrency and instances
Max concurrency 1 means each instance handles 1 request at a time; max instances 5 means 5 instances available.Step 2: Calculate handling capacity and queuing
5 instances x 1 request = 5 requests handled immediately; remaining 5 requests wait in queue.Final Answer:
5 requests are handled immediately, 5 wait in queue -> Option DQuick Check:
Requests handled = concurrency x instances; excess queue [OK]
Quick Trick: Requests beyond capacity wait, not all handled at once [OK]
Common Mistakes:
- Assuming all requests handled simultaneously
- Thinking requests fail or drop immediately
- Confusing concurrency with total requests
