How does AWS Lambda reuse execution environments to improve performance when handling multiple requests?

hard📝 Application Q9 of 15

AWS - Lambda

ABy creating a new environment for every request to avoid state issues

BBy keeping the environment alive for some time after invocation to serve new requests

CBy storing function state permanently in the environment

DBy running multiple functions in the same environment simultaneously

Step-by-Step Solution

Solution:

Step 1: Understand environment reuse
Lambda keeps the environment alive briefly after a request to reuse it for subsequent requests, reducing startup time.
Step 2: Eliminate incorrect options
New environment per request increases latency; state is not stored permanently; environments do not run multiple functions simultaneously.
Final Answer:
By keeping the environment alive for some time after invocation to serve new requests -> Option B
Quick Check:
Environment reuse = alive briefly for next requests [OK]

Quick Trick: Lambda reuses environments briefly after invocation [OK]
