AWS - Lambda

Given this Python Lambda function code snippet using a layer for shared utilities:

import shared_utils

def lambda_handler(event, context):
    return shared_utils.process(event)

What will happen if the Lambda function is invoked but the layer is not attached?

AThe function will timeout waiting for the layer

BThe function will run successfully without errors

CThe function will return None silently

DThe function will raise a ModuleNotFoundError for 'shared_utils'

Step-by-Step Solution

Solution:

Step 1: Understand import behavior without layer
If the layer providing shared_utils is missing, Python cannot find the module and raises an error.
Step 2: Identify the error type
Python raises ModuleNotFoundError when an import fails.
Final Answer:
The function will raise a ModuleNotFoundError for 'shared_utils' -> Option D
Quick Check:
Missing layer = ModuleNotFoundError [OK]

Quick Trick: Missing layer means missing module, causing import error [OK]
