Option A is incorrect as it pertains to system enhancements which is different from preventive maintenance. Option B is incorrect as it pertains to diagnosing and correcting errors which is more of a reactive approach to maintenance. Option C pertains to making changes to improve efficiency but may not necessarily be preventive in nature.

Question 7

____ means examining the whole in order to learn about the individual elements.

Accepted Answer

Analysis involves breaking down a complex system into its individual components and examining how they work together as a whole. Synthesis, on the other hand, involves combining individual parts to create a unified whole. Risk management and risk identification are not related to the process of examining a whole to learn about individual elements.

Question 8

In a typical system, the initial version of the system is 1.0, and the release that includes the first set of maintenance changes is version ____.
