Quick Answer
The answer is service tasks, along with service address and incident type, as the three core components that can be defined in a Dynamics 365 Field Service work order. Service tasks break down the work into specific, actionable steps that technicians must complete, ensuring consistency and compliance during on-site visits. The service address is critical because it provides the exact physical location for scheduling, routing, and dispatching resources, typically pulled from the customer or service account record. On the MB-910 exam, this question tests your understanding of the foundational building blocks of a work order, often appearing as a select-three scenario where distractors like “product inventory” or “invoice total” might tempt you—but remember, these are outputs or separate entities, not core components. A strong memory tip is to think of the acronym SAT: Service tasks, Address, and incident Type—the three pillars that define what, where, and why for every field service job.
This MB-910 practice question tests your understanding of describe dynamics 365 field service. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
Service address
A service address is a core component of a work order in Dynamics 365 Field Service because it defines the physical location where the on-site service will be performed. This address is used for scheduling, routing, and dispatching resources, and it is typically populated from the customer account or service account record.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse operational work order fields (like service address, products, and service tasks) with financial or CRM fields (like purchase order number or credit score), which are not part of the standard work order definition in Field Service.
Detailed technical explanation
Under the hood, the work order entity in Dynamics 365 Field Service uses a service address lookup that references the customer's primary address or a custom service location. This address is critical for the Resource Scheduling Optimization (RSO) engine, which calculates travel time and distance using Bing Maps or Azure Maps. In a real-world scenario, if the service address is incorrect, the dispatcher may route a technician to the wrong site, causing delays and customer dissatisfaction.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
