Performance and security are critical considerations when working with JSON in modern applications. Ensuring JSON data is optimized for transmission, storage, and processing can significantly impact an application’s efficiency. Security is equally vital to protect JSON data from vulnerabilities like injection attacks and unauthorized access.
Understanding the best practices and tools for managing JSON performance and security prepares developers for real-world challenges and boosts confidence during interviews. The following MCQs will help you enhance your knowledge of these essential topics.
1.) What is a common vulnerability associated with parsing untrusted JSON?
2.) Which tool can be used to measure JSON parsing performance in JavaScript?
3.) Which of the following ensures JSON data is safe from injection attacks?
4.) Why should large JSON files be paginated in APIs?
5.) What is the purpose of using JSON Web Tokens (JWT)?
6.) Which of these techniques can prevent excessive JSON data exposure in APIs?
7.) How can large nested JSON objects impact performance?
8.) Which attack can occur when JSON data is excessively large and causes resource exhaustion?
9.) Which HTTP header is critical for securing JSON responses?
10.) What is one method to detect changes in JSON data?
