Explanation
Smart Grid Gateway (SGG) is a product that provides integration between Oracle Utilities Meter Data Management and various head-end systems that communicate with smart meters. SGG supports inbound and outbound communication between the two systems using web services and message queues. According to the Oracle Utilities Smart Grid Gateway User Guide, if a project is setting up meter commands with a head-end system (HES), two components that should be configured to support the inbound responses from HES are:
* Inbound web services: These are web services that are exposed by SGG to receive messages from HES.
Inbound web services can be used to receive responses from HES for commands that were sent by SGG or other systems.
* Message sender: This is a component that sends messages from SGG to other systems using message queues. Message sender can be used to send responses from HES to Oracle Utilities Meter Data Management or other systems.

Explanation
Time-of-use (TOU) maps can be used by various functions in Meter Data Management (MDM). A TOU map is a configuration that defines how interval measurements are converted into scalar measurements based on different TOU periods. A typical scenario in which TOU maps are applied is to usage transactions and final measurements for billing and analytical purposes. A usage transaction is a record that stores the bill determinants and other usage information for a usage subscription. A final measurement is a record that stores the measurement data that has been validated, edited, and estimated. TOU maps can be applied to usage transactions and final measurements to calculate bill determinants or perform analysis based on different TOU periods.
TOU maps are not applied to initial measurement data (IMD) records for creating summarized TOU final measurements. IMD records are records that store the raw measurement data that is received from smart meter systems or other sources. IMD records are not converted into final measurements by using TOU maps, but by using VEE rules.
TOU maps are not used to determine the time a user worked on an incorrect measurement, which is a function that is performed by using audit trails or logs. TOU maps are not used to map usage data with geospatial applications, which is a function that is performed by using location data or coordinates.

Explanation
Consumption synchronization is a process that ensures that the usage data from different measuring components (such as interval and scalar) are consistent and aligned. Consumption synchronization can be performed using various methods, such as adjustment, estimation, or derivation. According to the Oracle Utilities Meter Data Management Business User Guide, two types of VEE rules that are typically configured on a project for consumption synchronization processes are:
* Interval adjustment from scalar: This is a rule that adjusts the interval curve to match the register consumption. Interval adjustment from scalar can be used to correct any discrepancies between interval and scalar usage data due to factors such as clock drift or multiplier errors.
* Sum check: This is a rule that ensures that the usage data from two measuring components are in sync.
Sum check can be used to compare the usage data from different measuring components (such as import and export) and flag any differences or errors.

Explanation
A time-of-use (TOU) template is used to define the start and end times of TOU periods for different days of the week and seasons of the year. A TOU template has an interval size that controls the values allowed as start and end times. For example, if the interval size is 60 minutes, then the start and end times must be multiples of
60 minutes, such as 00:00, 01:00, 02:00, and so on. A TOU template can be used to generate TOU data for TOU maps whose seconds per interval (SPI) is divisible by the template's SPI. For example, if the template's SPI is 3600 (60 minutes), then it can be used to generate TOU data for TOU maps whose SPI is 3600, 1800 (30 minutes), 1200 (20 minutes), 900 (15 minutes), 600 (10 minutes), 300 (5 minutes), and so on. Therefore, the correct answer is D.
