Answer: Create new synthetic clients to simulate a user journey using the application., Use current and historic Request Logs to trace customer interaction with the application.
To measure application reliability from a user perspective without making any engineering changes, the best approaches are to create new synthetic clients to simulate a user journey (D) and use current and historic Request Logs to trace customer interaction (E). Synthetic clients (D) allow you to simulate real user interactions without altering the application, providing insights into reliability from a user's perspective. Analyzing current and historic Request Logs (E) gives you a passive way to understand how users are interacting with your application and identify any issues they might be facing, all without the need for code changes. Options A and B involve making changes to the application or its monitoring setup, which contradicts the requirement of not making engineering changes. Option C is limited as it only considers the response time from web proxy logs, which doesn't fully capture the user's experience or reliability.

You manage a high-traffic web application running on Google Cloud Platform (GCP). Without modifying the application's code, you need to assess its reliability from the user's perspective. Which two actions should you take?
A
Review current application metrics and add new ones as needed.
B
Modify the code to capture additional information for user interaction.
C
Analyze the web proxy logs only and capture response time of each request.
D
Create new synthetic clients to simulate a user journey using the application.
E
Use current and historic Request Logs to trace customer interaction with the application.
