The correct answer is capturing customer signatures, as this is a core capability of the Dynamics 365 Field Service mobile app that enables technicians to obtain proof of service directly on-site. This feature is essential because it allows field workers to complete work orders without returning to the office, ensuring immediate validation of service delivery through a legally recognized digital signature. On the MB-910 exam, this question tests your understanding of what the mobile app can do versus back-office or system-level functions; a common trap is confusing mobile capabilities with features like automatic scheduling optimization or IoT device management, which require server-side processing. Remember that the Field Service mobile app is designed for on-the-go tasks—viewing schedules, logging work, and capturing signatures—while administrative actions like creating customer accounts or managing IoT alerts happen in the backend. A useful memory tip: think of the mobile app as the technician’s “digital clipboard” for field execution, not for system configuration.
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 of the following are capabilities of the Dynamics 365 Field Service mobile app?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
View assigned work orders and schedule
The Field Service mobile app allows technicians to view their schedule and work orders, and also capture customer signatures for proof of service. Option A is incorrect because automatic scheduling optimization is not done in the mobile app. Option D is incorrect because creating new customer accounts is typically done in the back office, not the mobile app. Option E is incorrect because IoT device management is not a mobile app feature.
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.
✓
View assigned work orders and schedule
Why this is correct
Technicians can view their schedule.
Related concept
Static NAT maps one inside address to one outside address.
✗
Automatic scheduling optimization
Why it's wrong here
Scheduling optimization is done by RSO, not the mobile app.
✓
Capture customer signatures
Why this is correct
Mobile app supports signature capture.
Related concept
Static NAT maps one inside address to one outside address.
✗
Configure IoT device alerts
Why it's wrong here
IoT configuration is in Connected Field Service, not mobile app.
✗
Create new customer accounts
Why it's wrong here
Customer account creation is typically done in the back office.
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.

What is the correct answer to this question?
The correct answer is: View assigned work orders and schedule — The Field Service mobile app allows technicians to view their schedule and work orders, and also capture customer signatures for proof of service. Option A is incorrect because automatic scheduling optimization is not done in the mobile app. Option D is incorrect because creating new customer accounts is typically done in the back office, not the mobile app. Option E is incorrect because IoT device management is not a mobile app feature.
What should I do if I get this MB-910 question wrong?

Variation 1. Which TWO of the following are benefits of using Dynamics 365 Field Service mobile app?
easy
A.Allow customers to schedule their own appointments.
✓ B.Capture customer signatures on site.
C.Automatically record time without technician input.
D.Manage inventory levels in real time.
✓ E.View work order details offline.
Why B: Options A and C are correct. The mobile app allows viewing work orders offline and capturing signatures. Option B is wrong because time entries are typically recorded on the app, not automatically. Option D is wrong because the app does not manage inventory. Option E is wrong because the app is for technicians, not customers.
