200-901 Cisco Platforms and Development Practice Question
A developer is building an integration with Cisco Meraki and needs to handle rate limiting. Which two responses indicate rate limiting and how should they be handled? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between proactive headers (like X-RateLimit-Remaining) and reactive responses (like 429 and Retry-After), so candidates mistakenly choose the header that warns about limits rather than the actual rate-limiting response.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Retry-After header with wait time in seconds
The Retry-After header explicitly tells the client how long to wait before retrying a request, which is the standard way to handle rate limiting. Option C is correct because HTTP status code 429 (Too Many Requests) is the definitive signal from the server that the client has exceeded the allowed rate limit. Together, these two responses allow a developer to identify and respond to rate limiting by pausing requests for the specified duration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
X-RateLimit-Remaining header
Why it's wrong here
Meraki does not include this header; it uses Retry-After.
- ✓
Retry-After header with wait time in seconds
Why this is correct
Retry-After tells how long to wait.
- ✓
HTTP status code 429
Why this is correct
429 is the rate limit status code.
- ✗
Link header with rel="next"
Why it's wrong here
Link header is for pagination, not rate limiting.
- ✗
HTTP status code 503
Why it's wrong here
503 is service unavailable, not rate limiting.
