To select all of the containers in a particular state or province in Territory Planning, there are two ways: adding the state field to the container-legend and using it to search and select from the legend, or using the selection tools and selecting them from the map. Adding the state field to the container-legend allows the user to filter containers by state and select all containers that match a certain state value1. Using the selection tools, such as rectangle or polygon, allows the user to draw a shape on the map and select all containers that fall within that shape1. Using the state/province selection mode is not a valid option, as this mode is only available for units (accounts), not containers1. Adding the state field to the unit-legend is also not a valid option, as this will only allow selecting units (accounts), not containers1.

The implementation team is responsible for business and IT sanity testing post deployment to production. Sanity testing is a type of software testing executed on the stable build of an application with minor code changes. It is also known as surface-level testing. A sanity test is performed to ensure the application works as expected after the bug fixes or changes in the code1. The implementation team, which consists of developers, testers, and business analysts, conducts sanity testing to verify the functionality and performance of the application after deployment2. The project manager, the Salesforce support team, and the customer are not directly involved in sanity testing post deployment.

Explanation
Maps Live Asset Daily Summary is the object that the Admin should include in a Salesforce Report to see the total distance traveled each day by a Sales Rep. Maps Live Asset Daily Summary is a custom object that stores information about the daily activities of a Maps Live Asset, such as a vehicle or a mobile device3. One of the fields in this object is Total Distance Traveled, which captures the total distance traveled by the asset in miles or kilometers4. By creating a report based on this object, the Admin can compare the actual distance traveled to the distance submitted by each Sales Rep for reimbursement. Maps Live Asset Daily Summary Event, Maps Live Event, and Maps Route are not the correct objects for this purpose.

According to the Salesforce Maps documentation1, to create a data layer, the admin must first select either the Personal or Corporate folder in the Layers tab. The Personal folder is for saving data layers privately so only the admin can see them, while the Corporate folder is for sharing data layers with other maps users. After selecting a folder, the admin can hover over New and select Data Layer, then name the data layer and select the data source, filter, and style options. If the admin does not select a folder before attempting to create a layer, all of the options will be greyed out and unavailable. Reference:

According to the Salesforce Maps documentation1, when using the limit areas by attribute option during an optimization, some units may be trimmed from the areas and assigned to a specific area or the unassigned bucket, depending on the leftover unit assignment setting. To visualize these leftover units, the user must open the alignment using the "Include Unassigned Units" option, which will display all units in the data set, regardless of whether they are assigned to an area or not. This option can be found in the Alignment Settings window, under the Data tab2. By selecting this option, the user can see the leftover units on the map and in the legend, and decide how to handle them. Reference:
