350-201 Question 259
Select 3A team is integrating a Cisco SecureX API into their security automation workflow. During testing, they encounter intermittent failures, such as requests not being processed and delays in response. What constraints should the team consider to address these issues?
- A
Rate limiting imposed by the API, which restricts the number of requests within a specific time window
- B
Payload size restrictions that might cause failures if the data exceeds the allowed limit
- C
Authentication method of the API, as it may require token renewal or re-authentication
- D
API timeout settings, which could terminate requests that take too long to process
- E
API versioning, which ensures backward compatibility of older API calls
Show answer and explanation
Correct answers: A, B, D
Explanation
In the given scenario, the team is facing intermittent API failures that are likely due to common constraints such as rate limiting, payload restrictions, or timeout settings. Understanding and addressing these constraints can help ensure stable and reliable API integrations.
- A. Correct.
Rate limiting is a common constraint for APIs to prevent excessive traffic or abuse, and exceeding this limit can cause intermittent failures.
- B. Correct.
Payload size restrictions are often enforced by APIs to ensure data efficiency and security. If the payload is too large, the request may fail.
- C. Incorrect.
While authentication is essential, it is not directly related to the intermittent failures described in the scenario. Token renewal issues would result in authentication errors instead.
- D. Correct.
Timeout settings are a critical factor, as APIs often have a maximum processing time for requests. Requests taking too long may be terminated.
- E. Incorrect.
API versioning ensures compatibility and does not directly cause intermittent failures unless the integration is using an unsupported version, which is not indicated in this scenario.
