You are estimating the efforts for Dynamics 365 Supply Chain Management implementation. 
What tool should help you with the estimations and implementation?

Answer options:

A.Dataverse Plugin Registration Tool
B.Dynamics Guides
C.Dynamics Remote Assist
D.Dynamics Lifecycle Service
E.XrmToolBox

Correct Answer: D 
Microsoft Dynamics 365 suite of business applications includes two parts: Customer Relationship Management (CRM) and Enterprise Resource Planning (ERP). 
Dynamics 365 ERP applications include: Commerce — provides a multichannel solution that unifies back-office, in-store, call center, and digital services.
Finance — provides automation of global financial operations based on performance monitoring and predictions and helps users make data-driven decisions.
Human Resources — provides human resource management, like employee retention, training, performance management, etc.
Supply Chain Management — provides management of the manufacturing and supply chain operations.
All current Dynamics 365 ERP versions are cloud-based. But customers can install on-premises the following Dynamics 365 ERP applications: Finance, Supply Chain Management, and Commerce. 
To implement Dynamics 365 Supply Chain Management or Dynamics 365 Finance applications, you need to use Microsoft Dynamics Life Service (LCS). LCS is a portal that provides information about product implementations and can give you a realistic assessment of the migration efforts. In addition, the portal supports all project phases and helps you manage the project by offering various checklists, tools, and prebuilt methodologies.
Option A is incorrect because the Dataverse Plugin Registration Tool is for registering the Dataverse plugins but not for Dynamics 365 Supply Chain Management implementation.
Option B is incorrect because the Dynamics Guides application provides holographic step-by-step instructions to the employees in the actual work situation, but it is not for Dynamics 365 Supply Chain Management implementation.
Option C is incorrect because the Remote Assist application provides real-time help from the experts using HoloLens or Dynamics 365 Remote Assist mobile, but it is not for Dynamics 365 Supply Chain Management implementation.
Option E is incorrect because the XrmToolBox is a set of over 30 tools for the Dataverse administration, customization, and configuration, but it is not for Dynamics 365 Supply Chain Management implementation.
