In troubleshooting, what is the very first question you should ask to identify the problem?

• A. What is the last time the system rebooted?
• B. What has recently changed?
• C. Who last used the device?
• D. Is the device connected to the network?

Answer: (B)

What changed recently is the most informative starting point in troubleshooting. A new software install, update, configuration tweak, driver change, or environment alteration can easily trigger the kinds of problems you’re seeing. Asking about recent changes lets you form a quick, focused hypothesis: the issue is linked to that change, so you can review the change, test its impact, and decide whether a rollback or adjustment is needed. This approach speeds up diagnosis by targeting likely causes rather than exploring unrelated aspects. Other questions tend to address symptoms or isolated details. For example, asking when the system last rebooted helps with uptime or history but doesn’t reveal what started the problem. Asking who last used the device is usually not diagnostic. Checking whether the device is connected to the network points to connectivity issues, which may be a consequence rather than the root cause, and won’t help uncover non-network-related failures.
