The answer is that the device filter fails because the device.skuFamily property is case-sensitive and may not match 'Professional'. In Microsoft Intune, when you create a device filter rule targeting a specific SKU family, the string value you provide must exactly match the case of the property as reported by the device; if the actual SKU family is stored as 'Professional' with a different casing—such as 'professional' or 'PROFESSIONAL'—the filter will not apply, even if the OS build and edition are correct. This question tests your understanding of Intune device filter case sensitivity, a common trap on the MD-102 exam where candidates overlook that property values like skuFamily are case-sensitive while others, such as operatingSystemSKU, are not. A reliable memory tip is to think of SKU as a proper name: always match the exact casing you see in a device’s actual inventory data, not what you assume it should be.
MD-102 Manage and maintain devices Practice Question
This MD-102 practice question tests your understanding of manage and maintain devices. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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
{
"DeviceFilter": {
"Name": "Windows 10 Pro devices",
"Rule": "(device.osVersion -startsWith \"10.0.1904\") and (device.deviceType -eq \"Windows\") and (device.skuFamily -eq \"Professional\")"
}
}
Refer to the exhibit. You are creating a device filter in Microsoft Intune to target a policy to Windows 10 Pro devices. The filter should only apply to devices running OS build 1904x (20H1 or later). However, some devices with build 1904x and SKU Professional are not receiving the policy. What is the most likely reason?

Correct answer & explanation
✓
The device.skuFamily property value is case-sensitive and may not match 'Professional'.
Option D is correct because the `device.skuFamily` property in Microsoft Intune is case-sensitive. When creating a device filter rule, the value 'Professional' must exactly match the case of the SKU family string returned by the device. If the actual SKU family is reported as 'Professional' with a different casing (e.g., 'professional' or 'PROFESSIONAL'), the filter will not match, causing the policy not to apply to those devices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 -startsWith operator does not work for osVersion property.
Why it's wrong here
-startsWith works for string properties.
✗
The device must be enrolled via Autopilot for filters to apply.
Why it's wrong here
Filters apply to all enrollment types.
✗
The filter rule syntax is incorrect because of the parentheses.
Why it's wrong here
Parentheses are valid.
✓
The device.skuFamily property value is case-sensitive and may not match 'Professional'.
Why this is correct
Case sensitivity can cause mismatches.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume property values in Intune filters are case-insensitive, leading them to overlook the exact casing requirement for `device.skuFamily`, and instead focus on unrelated syntax or enrollment requirements.
Detailed technical explanation
How to think about this question
Under the hood, Intune device filters evaluate rule expressions against device properties retrieved from the Microsoft Graph API. The `device.skuFamily` property corresponds to the Windows SKU (e.g., Professional, Enterprise, Education) and is case-sensitive because it is stored as a string in the device object. A real-world scenario where this matters is when a device's SKU is reported as 'Professional' but the filter rule uses 'professional' (lowercase), causing the policy to silently fail to apply. This case sensitivity is a common source of filter misconfiguration.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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. 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.
