Actual exam question for Oracle's 1Z0-1091-22 exam
Question #: 25
Topic #: 2
[All 1Z0-1091-22 Questions]

Your client requests you to design and set up data necessary to support an electric meter that is installed at a customer's service point with solar panels:

* Channel 1: Measures the kWh that was consumed from the grid. This is an interval channel that measures in 60-minute intervals.

* Channel 2: Measures the kWh that was generated. This is an interval channel that measures in 60-minute intervals.

Using the Math usage rule, you must create usage transactions that take the difference between the consumed and generated channels, store and name the difference value, and store the derived curve.

Which THREE statements are true?

Suggested Answer: A, B, C

The client requests to design and set up data necessary to support an electric meter that is installed at a customer's service point with solar panels. The meter has two channels that measure the kWh that was consumed from the grid and the kWh that was generated. Using the Math usage rule, usage transactions that take the difference between the consumed and generated channels must be created and stored. According to the Oracle Utilities Meter Data Management Business User Guide, some statements that are true about this scenario are:

The two channels need distinct service quantity identifiers (SQIs) to differentiate between the generated and consumed kWh. SQIs are codes that identify different types of usage data, such as kWh, kVARh, or kW. SQIs can be used to specify which usage data should be used for calculation or validation purposes.

Net consumption SQI is required. This is a code that identifies the usage data that represents the difference between the consumed and generated kWh. Net consumption SQI can be used to store and name the difference value and export it to other systems.

You must set ''Save Derived Vector'' to Yes in the Math usage rule. This is a parameter that indicates whether the derived curve that results from the Math usage rule should be saved or not. Setting this parameter to Yes can be used to store the derived curve that represents the net consumption.

I'm just glad we don't have to worry about measuring the solar flares. That would really complicate things.

Whoa, hold up! Aren't we supposed to be designing an electric meter, not a rocket ship? This is getting a little too complex for my taste.

A separate service point for the solar panels? That's just overkill. The net consumption SQI should handle that.

Saving the derived vector is crucial to keep track of the net consumption. Can't miss that one.

Definitely need distinct SQIs for generated and consumed kWh. That's basic metering stuff.

I'm not sure about statement D. Do we really not need a net consumption SQI?

I agree with that. I also believe statement C is true because we need to save the derived curve.

I think statement A is true because we need to differentiate between the two channels.
