The answer is a Dynamics 365 Field Service license and Resource scheduling (scheduling engine). These two components are required because the Field Service license grants user access to the application, while the scheduling engine is the core technical backbone that enables dispatchers to assign work orders to field technicians based on availability and location. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this question tests your understanding of the minimum prerequisites for a basic Field Service solution, often appearing as a trap where learners mistakenly include Customer Service or Sales, which are separate apps and not mandatory. A common memory tip is to remember that Field Service is built around dispatching, so you need the license to enter the system and the scheduling engine to move work; think “license to log in, scheduling to send.”
MB-910 Describe Dynamics 365 Field Service Practice Question
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.
Which TWO components are required to set up a basic Dynamics 365 Field Service solution? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Dynamics 365 Field Service license
Options A and D are correct. A Dynamics 365 Field Service license is required for users. Resource scheduling (scheduling engine) is a core component for dispatching. Option B is wrong because Customer Service is a separate app, not required for Field Service. Option C is wrong because Power Automate is optional for workflows. Option E is wrong because Dynamics 365 Sales is not required.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Dynamics 365 Sales license
Why it's wrong here
Sales is not required for Field Service.
✗
Power Automate license
Why it's wrong here
Power Automate is optional for automation.
✗
Dynamics 365 Customer Service license
Why it's wrong here
Customer Service is not required for basic Field Service.
✓
Dynamics 365 Field Service license
Why this is correct
A license is necessary to access the Field Service app.
Related concept
Static NAT maps one inside address to one outside address.
✓
Resource scheduling (scheduling engine)
Why this is correct
Resource scheduling is a core component for dispatching.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MB-910 NAT questions on configuration and troubleshooting.
