Which of the following is part of identifying the solution when troubleshooting an issue?

Spotting symptoms is part of the broader information gathering process, but 'gathering information' encompasses all initial data collection needed to define the problem.

Determining if anything has changed is a specific type of information gathered, contributing to problem analysis, but it's not the overall act of identifying the solution itself.

Testing the theory occurs after a potential solution or cause has been identified and hypothesized, not as part of the initial identification of the solution.

Duplicating the problem is often used to confirm symptoms and gather more data, which is part of the information gathering and problem definition phase, not the direct identification of the solution.

Gathering information is the crucial initial step in troubleshooting, as it helps define the problem, understand its scope, and collect all necessary details from users, logs, and system diagnostics to formulate potential solutions.
