AWS - Lambda

Why should environment variables in AWS Lambda be considered immutable during a single invocation?

ABecause Lambda freezes the execution environment and variables cannot change mid-run

BBecause environment variables are stored in a database

CBecause Lambda automatically resets variables every second

DBecause environment variables are encrypted and cannot be decrypted

Step-by-Step Solution

Solution:

Step 1: Understand Lambda execution environment
Lambda freezes the environment during invocation, so environment variables remain constant and cannot be changed mid-execution.
Step 2: Eliminate incorrect options
Env vars are not stored in a database, not reset every second, and encryption does not prevent runtime access.
Final Answer:
Because Lambda freezes the execution environment and variables cannot change mid-run -> Option A
Quick Check:
Env vars immutable during invocation due to frozen environment [OK]

Quick Trick: Env vars stay constant during Lambda invocation [OK]
