Oracle Exam 1Z0-1091-22 Topic 6 Question 5 Discussion

A virtual meter is a meter that does not physically exist but is used to represent the usage of a group of meters or a portion of a meter. A virtual meter can be used to perform various calculations or adjustments on usage data, such as aggregation, derivation, allocation, or net metering. According to the Oracle Utilities Meter Data Management Business User Guide, to bill the university correctly for a new fast food restaurant that is being installed at the center of the university and whose usage will also be included in the university's master meter, the correct step is:

Use derivation algorithms to exclude the restaurant's usage from the master meter. This can be done by creating a virtual meter that represents the master meter minus the restaurant's meter and applying a derivation algorithm that subtracts the restaurant's usage from the master meter's usage. The virtual meter's usage can then be used for billing the university.
