- A
Ignore the error and continue, as 429 is a temporary issue.
Why wrong: Continuing to send requests will likely result in further errors.
- B
Wait for the number of seconds specified in the Retry-After header before retrying.
The Retry-After header indicates how long to wait.
- C
Switch to a different base URL to bypass the limit.
Why wrong: The rate limit applies to the API, not the base URL.
- D
Increase the request rate by using multiple API keys in parallel.
Why wrong: This would likely violate rate limits further.

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 using the Meraki Dashboard API to retrieve a list of clients for a network. The API returns a 429 error. What should the developer do to handle this correctly?
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
✓
Wait for the number of seconds specified in the Retry-After header before retrying.
A 429 HTTP status code indicates 'Too Many Requests,' meaning the client has exceeded the rate limit imposed by the Meraki Dashboard API. The correct handling is to respect the Retry-After header, which specifies the number of seconds the client must wait before retrying the request, as per RFC 7231 Section 7.1.3. This ensures compliance with API rate limits and prevents further throttling or temporary blocking.
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 misconception that 429 is a transient error like a 503 Service Unavailable, leading candidates to think they can simply retry immediately or ignore it, rather than understanding that 429 specifically requires honoring the Retry-After header for rate-limit compliance.
Detailed technical explanation
How to think about this question
The Retry-After header can contain either a decimal integer (seconds) or an HTTP-date, and the client must parse it accordingly. Under the hood, the Meraki Dashboard API uses a token bucket or sliding window algorithm to enforce rate limits, typically allowing a burst of requests followed by a cooldown period. In real-world scenarios, failing to respect Retry-After can lead to a 403 Forbidden or a temporary IP block, especially if the client is using a shared API key in a CI/CD pipeline.
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.
