Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switch the API endpoint to use the Free pricing tier.
Why it's wrong here
Free tiers have lower limits and will exacerbate throttling.
- ✗
Regenerate the subscription key and restart the client service.
Why it's wrong here
Regenerating keys does not resolve rate limit throttling.
- ✗
Immediately re-submit the request with doubled payload size.
Why it's wrong here
Increasing payload size will worsen quota or size limit issues.
- ✓
Implement an exponential backoff retry policy and resend the request after a delay.
Why this is correct
Rate limit errors require backing off and retrying after the specified Retry-After duration.
