Why do batch operations reduce round trips even when some individual requests in the batch fail?

hard📝 Conceptual Q10 of 15
Rest API - Batch and Bulk Operations
Why do batch operations reduce round trips even when some individual requests in the batch fail?
ABecause batch operations only send successful requests
BBecause the entire batch is sent and responded to in one network call regardless of individual failures
CBecause failed requests are automatically retried by the server
DBecause failed requests do not count as round trips
Step-by-Step Solution
Solution:
  1. Step 1: Understand batch request network behavior

    The batch is sent as one request and the server replies once with all results.
  2. Step 2: Analyze impact of individual failures

    Failures inside the batch do not cause extra network calls; the batch round trip remains one.
  3. Final Answer:

    Because the entire batch is sent and responded to in one network call regardless of individual failures -> Option B
  4. Quick Check:

    Batch sends one network call even if some requests fail = C [OK]
Quick Trick: Batch is one call even if some requests fail [OK]
Common Mistakes:
MISTAKES
