hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Identify cold start reduction methods
Invoking the function periodically keeps the environment warm, reducing cold starts.Step 2: Evaluate other options
Increasing timeout does not reduce cold starts; larger memory helps performance but not cold start directly; disabling reuse increases cold starts.Final Answer:
Keep the function warm by invoking it periodically -> Option AQuick Check:
Periodic invocation reduces cold starts [OK]
Quick Trick: Invoke Lambda regularly to keep environment warm [OK]
Common Mistakes:
- Assuming timeout affects cold start
- Blindly increasing memory without testing
- Disabling environment reuse
