AWS - SNS and SQS
A developer tries to send a message to an AWS SQS queue but gets an error. What could be a likely cause?
AThe queue automatically deletes all messages
BThe message size is below the minimum allowed
CThe message is sent without any permissions

Step-by-Step Solution

  1. Step 1: Identify common SQS send errors

    Incorrect or missing queue URL often causes send failures.

  2. Step 2: Evaluate other options

    Message size below minimum is not an error; queues do not auto-delete all messages; permissions errors are possible but less common than URL issues.

    The queue URL is incorrect or missing -> Option D

  4. Quick Check:

    Incorrect queue URL causes send errors [OK]
Quick Trick: Check queue URL first when send fails [OK]
Common Mistakes:
  • Ignoring queue URL correctness
  • Assuming message size below minimum causes errors
  • Overlooking permission issues
