A+ Question of the Week

Which of the following would be considered software preventative maintenance?

1. Upgrading the operating system
2. Reinstalling an application that is not functioning correctly
3. Restoring a volume from a backup set
4. Defragmenting a hard-drive volume

The correct answer is 4.

Preventative maintenance (PM) seeks to proactively treat a component or system before it fails, in an effort to prolong the time before actual failure. Among the options, only defragmentation is a software form of PM. Upgrading the operating system is not the same as updating it, which would be a form of PM. The remaining two options are reactive, rather than proactive.
