The correct answer is the Field Service Mobile app because it is the dedicated Dynamics 365 component that equips technicians with work order details, step-by-step instructions, and offline data capture for serial numbers and photos directly at the customer site. This app is purpose-built for field service usage, allowing technicians to follow structured task flows without needing a constant internet connection, which is critical for on-site installations. On the MB-910 exam, this question tests your understanding of the distinct roles within Dynamics 365 applications: the Field Service Mobile app is for technicians in the field, while the Customer Service workspace is for agents at a desk. A common trap is confusing the Field Service Mobile app with Power Apps, but remember that Power Apps is a low-code platform for building custom apps, not a ready-to-use field service tool. Memory tip: think “Mobile for the field, workspace for the desk” to keep the roles straight.
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.
A technician is dispatched to install a new piece of equipment at a customer site. Which Dynamics 365 Field Service component should the technician use to view step-by-step instructions and capture data like serial numbers and photos?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Field Service Mobile app
Option B is correct because the Field Service Mobile app provides technicians with work order details, step-by-step instructions, and the ability to capture data offline. Option A is wrong because the Customer Service workspace is for agents, not field technicians. Option C is wrong because Power Apps is a low-code platform, not a ready-to-use field service app. Option D is wrong because Dynamics 365 Remote Assist is for remote collaboration, not structured task completion.
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.
✗
Power Apps mobile app
Why it's wrong here
Power Apps is a platform to build custom apps, not a specific field service app.
✗
Customer Service workspace
Why it's wrong here
This is for customer service agents, not field technicians.
✓
Field Service Mobile app
Why this is correct
The mobile app is designed for technicians to view and complete work orders offline.
Related concept
Static NAT maps one inside address to one outside address.
✗
Dynamics 365 Remote Assist
Why it's wrong here
Remote Assist is for video calls and sharing, not for step-by-step instructions.
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.
