                                        Changed Block Tracking is a hypervisor-level feature that efficiently tracks blocks of data that have changed on a virtual machine disk since the last backup. By exposing this change log to backup software, it eliminates the need to scan entire virtual disks, drastically reducing backup windows and network bandwidth consumption. It is a foundational technology for modern efficient virtual machine data protection.<\/span><\/p>\n

                                          Correct Answer:<\/b> 2<\/b><\/p>\n

                                          Explanation:<\/b><\/p>\n

                                          The vmkernel.log file on ESXi hosts records low-level kernel activities, including storage multipathing status, path failures, hardware device drivers, and network packet routing. It serves as the primary diagnostic log for troubleshooting complex storage connectivity issues, SCSI command timeouts, and hardware interoperability warnings. Administrators rely heavily on this log during deep infrastructure audits.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
