When an administrator is troubleshooting a system, which of the following describes the NEXT course of action if a change does not solve the problem?
The correct answer is B. Reverse the change. Standard troubleshooting methodology requires reversing any change that fails to fix the problem before proceeding, preserving a clean baseline for further diagnosis.

Why each option
Standard troubleshooting methodology requires reversing any change that fails to fix the problem before proceeding, preserving a clean baseline for further diagnosis.
Establishing a new theory is appropriate but must follow - not precede - reversing the unsuccessful change to ensure the system is in a known baseline state.
The structured troubleshooting process mandates that an unsuccessful change must be reversed immediately to avoid compounding the original problem with additional unverified variables. Leaving a failed change in place obscures the true cause and makes subsequent troubleshooting attempts harder to evaluate. Only after restoring the system to its previous known state should a new theory or a different corrective action be considered.
Implementing the next logical change without first reversing the failed one stacks unverified modifications, making it nearly impossible to isolate the actual root cause.
Root cause analysis is conducted after the problem has been resolved to prevent recurrence, not as a reactive step when a fix attempt fails.
