AWS - Lambda
You set reserved concurrency to 0 for a Lambda function. What is the effect?
AThe function runs with unlimited concurrency.
BThe function is disabled and cannot be invoked.
CThe function queues all requests until capacity is available.
DThe function runs only one instance at a time.
Step-by-Step Solution
Solution:

  1. Step 1: Understand reserved concurrency set to zero

    Setting reserved concurrency to zero disables the function from running.

  2. Step 2: Identify invocation behavior

    All invocation requests are throttled and rejected because no concurrency is available.

  3. Final Answer:

    The function is disabled and cannot be invoked. -> Option B

  4. Quick Check:

    Reserved concurrency 0 = function disabled [OK]
Quick Trick: Reserved concurrency 0 disables Lambda function invocations [OK]
Common Mistakes:
  • Assuming zero means unlimited concurrency
  • Thinking requests queue instead of throttling
  • Believing function runs one instance only
