The correct answer is that a notification is sent to the customer that the technician is nearby. This happens because geofencing in Dynamics 365 Field Service creates a virtual boundary—in this case, a 1.5-mile radius around the customer site—and when the technician’s device enters that zone, the system triggers a predefined action, such as sending a customer notification or updating the booking status. On the MB-910 exam, this concept tests your understanding of how geofencing enhances customer communication and operational efficiency, often appearing as a scenario where you must distinguish between automatic notifications and other actions like completing work orders or syncing data. A common trap is assuming geofencing automatically completes the work order or syncs field data, but it only triggers events based on location entry or exit. Remember the memory tip: “Fence triggers, it doesn’t finish”—geofencing initiates notifications, not completions.
MB-910 Describe Dynamics 365 Field Service Practice Question

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.
Exhibit
Refer to the exhibit.
{
"FieldServiceSetting": {
"EnableGeofencing": true,
"GeofenceRadius": 1.5,
"GeofenceUnit": "miles",
"MobileOfflineSyncInterval": 15
}
}
Refer to the exhibit. A technician arrives within 1.5 miles of a customer site. What is expected to happen?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A notification is sent to the customer that the technician is nearby
The exhibit shows geofencing is enabled with a 1.5-mile radius. When the technician enters the geofence, the system can trigger actions like sending a notification to the customer that the technician is nearby, or updating the booking status. Option A is incorrect because the work order is not automatically completed. Option B is incorrect because geofencing does not automatically sync data. Option C is correct because geofencing can trigger a customer notification. Option D is incorrect because the schedule window is separate from geofencing.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The booking status changes to 'In Progress'
Why it's wrong here
Status change requires manual action.
✗
The work order is automatically completed
Why it's wrong here
Geofencing does not complete work orders.
✗
The mobile app syncs all offline data
Why it's wrong here
Sync interval is 15 minutes, not triggered by geofence.
✓
A notification is sent to the customer that the technician is nearby
Why this is correct
Geofencing can trigger customer notifications.
Related concept
Authentication checks who the user is.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. 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 Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related MB-910 questions on access control and AAA configuration.
