Quick Answer
The correct answer is DeviceProcessEvents, DeviceNetworkEvents, and DeviceFileEvents. These three tables are the foundational data sources for investigating a malware outbreak on a device because they capture the core behavioral indicators of an infection: process creation (e.g., suspicious executables), network connections (e.g., command-and-control traffic), and file modifications (e.g., dropped payloads). On the Microsoft 365 Administrator MS-102 exam, this question tests your ability to distinguish between device-centric hunting tables and cloud or email-focused tables, a common trap where candidates mistakenly select EmailAttachmentInfo or CloudAppEvents. A reliable memory tip is to think of the "device triad" — Process, Network, File — and remember that malware always leaves traces in at least two of these three areas on the endpoint itself.
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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.
You are a security analyst. You need to investigate a potential malware outbreak on a device using Microsoft Defender XDR. Which three data sources can you include in an advanced hunting query to gather relevant information? (Choose three.)
CloudAppEvents
Why wrong: This table is for cloud application events, not device-level events.
DeviceFileEvents
Contains file creation and modification events.
EmailAttachmentInfo
Why wrong: This table is for email attachments, not device-level events.
DeviceNetworkEvents
Contains network connection events.
DeviceProcessEvents
Contains process creation events.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
DeviceFileEvents
Options A, B, and C are correct because DeviceProcessEvents, DeviceNetworkEvents, and DeviceFileEvents are all standard tables in advanced hunting for process, network, and file activities. Option D is wrong because EmailAttachmentInfo is for email, not device. Option E is wrong because CloudAppEvents is for cloud apps.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
