300-445 Question 141
Select 3A large enterprise has deployed a web-based network assurance dashboard to monitor the health, performance, and security of their network. The dashboard relies on APIs to collect data from network devices and present it in real-time. Recently, the team has noticed delays and inaccuracies in the displayed information. Upon investigation, they found that the root cause is related to web API performance issues. What would be the most effective steps to address and mitigate the problem?
- A
Optimize the API queries to reduce the volume of data requested in each call.
- B
Implement caching mechanisms to store frequently accessed data temporarily.
- C
Upgrade the network devices to enable support for the latest API standards.
- D
Increase the polling interval for API data collection to reduce server load.
- E
Migrate the web-based dashboard to a cloud platform to improve scalability.
Show answer and explanation
Correct answers: A, B, D
Explanation
To address API performance issues in a web-based network assurance dashboard, steps like optimizing API queries, implementing caching, and adjusting the polling interval are effective in reducing server and network load while improving data accuracy and response times. While upgrading devices or migrating to the cloud may have other benefits, they do not directly tackle the root cause of the performance issue.
- A. Correct.
Optimizing API queries can help reduce the amount of data being transmitted, which improves response times and reduces the load on both the API server and the network.
- B. Correct.
Caching mechanisms can temporarily store data that is frequently accessed, reducing the need for repeated API calls and improving performance.
- C. Incorrect.
Upgrading network devices to newer API standards might improve capabilities but does not directly address performance issues related to delays and inaccuracies in the current setup.
- D. Correct.
Increasing the polling interval reduces the frequency of API calls, alleviating server and network load, which can help mitigate performance delays.
- E. Incorrect.
Migrating the dashboard to a cloud platform can improve scalability but does not directly address API performance issues caused by inefficient queries or polling intervals.
