                                  "Use hash values to ensure downloaded software matches the vendor's published version and hasn't been modified."


                                  질문 # 297

                                  Comprehensive and Detailed Explanation From Exact Extract:
                                  Event Viewer is the best tool to analyze the root cause of service failures in Windows. It provides detailed logs from system processes, including errors, warnings, and crash reports related to services and applications.
                                  When a service starts and stops unexpectedly, Event Viewer will often record the cause, such as dependency failures or access violations.
                                  B: Task Manager shows active processes but doesn't retain logs or causes of failure.
                                  C: Internet Options is used for configuring browser settings, not troubleshooting services.
                                  D: Process Explorer is powerful but more suited for live monitoring and detailed process trees, not post- failure log analysis.
                                  Reference:
                                  CompTIA A+ 220-1102 Objective 3.1: Given a scenario, troubleshoot common Windows OS problems.

                                  The man command displays the manual pages for other Linux commands. It provides detailed documentation, including usage, options, and descriptions, allowing users to read a command's official reference directly from the terminal.
