Quick Answer
The answer is Lead and Opportunity, as these two are the core entities in Dynamics 365 Sales. In the sales process, a Lead represents a potential customer who has shown initial interest, while an Opportunity tracks a qualified deal through its lifecycle, including stages like proposal and negotiation. Together, they form the backbone of the sales pipeline, distinguishing them from entities like Invoice or Order, which belong to the finance and fulfillment workflows. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this question tests your ability to differentiate between core sales entities and those tied to other modules, such as Customer Service or Finance. A common trap is confusing Order or Invoice with sales entities, but remember that sales focuses on pre-revenue activities, while Orders and Invoices handle post-sale transactions. To lock this in, think of the mnemonic "LO" for Lead and Opportunity—the two letters that launch every sale.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
