hard📝 Application Q8 of 15

AWS - Lambda

AUse SNS to fan out messages to Lambda from all queues

BCombine all queues into one and trigger Lambda once

CCreate separate event source mappings for each SQS queue to the same Lambda

DConfigure one event source mapping with multiple queue ARNs

Step-by-Step Solution

Solution:

Step 1: Understand event source mapping for SQS
Each SQS queue requires its own event source mapping to trigger Lambda.
Step 2: Evaluate other options
Combining queues is not straightforward; SNS fans out messages from topics, not queues; one mapping cannot have multiple ARNs.
Final Answer:
Create separate event source mappings for each SQS queue to the same Lambda -> Option C
Quick Check:
One event source mapping per SQS queue [OK]

Quick Trick: Use one event source mapping per SQS queue for Lambda triggers [OK]
