- A
X-RateLimit-Remaining header
Why wrong: Meraki does not include this header; it uses Retry-After.
- B
Retry-After header with wait time in seconds
Retry-After tells how long to wait.
- C
HTTP status code 429
429 is the rate limit status code.
- D
Link header with rel="next"
Why wrong: Link header is for pagination, not rate limiting.
- E
HTTP status code 503
Why wrong: 503 is service unavailable, not rate limiting.

200-901 Cisco Platforms and Development Practice Question
This 200-901 practice question tests your understanding of cisco platforms and development. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.)
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
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Under the hood, Cisco Meraki uses a token bucket algorithm for rate limiting, where each API key has a burst limit and a sustained rate. When the bucket is empty, the server returns a 429 response with a Retry-After header in seconds, and the client must wait that duration before retrying. In real-world scenarios, ignoring the Retry-After header can lead to repeated 429 responses and potential API key suspension, so developers should implement exponential backoff with jitter as a best practice.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
