300-445 Question 159
Single answerAn enterprise has implemented synthetic web testing to monitor its e-commerce website's performance and availability. The IT team notices that although the synthetic tests report the website as operational, actual users are experiencing intermittent failures during checkout. What is the most likely limitation of synthetic web tests in this scenario?
- A
Synthetic web tests cannot simulate real user behavior and traffic patterns.
- B
Synthetic web tests are unable to detect issues with backend systems like databases.
- C
Synthetic web tests are not designed to monitor website uptime metrics.
- D
Synthetic web tests cannot provide insights into the network infrastructure.
Show answer and explanation
Correct answer: A
Explanation
Synthetic web tests are useful for monitoring website performance and availability by simulating predefined user interactions. However, they are limited in their ability to replicate the diverse and unpredictable behavior of real users. In this scenario, intermittent failures during checkout may result from real-world usage patterns or high traffic, which synthetic tests do not accurately simulate.
- A. Correct.
Correct: Synthetic web tests simulate predefined user actions and may not account for the variability of real user behavior and traffic, leading to gaps in detecting certain issues.
- B. Incorrect.
Incorrect: While synthetic tests might not directly monitor backend systems, they can often detect issues indirectly if backend problems impact the simulated transactions.
- C. Incorrect.
Incorrect: Synthetic web tests are explicitly designed to monitor availability and performance, including uptime metrics.
- D. Incorrect.
Incorrect: Although synthetic web tests focus on application-level monitoring, they can indirectly indicate potential network issues through performance and latency measurements.
