The answer is the DeviceNetworkEvents table. This table is the correct choice because it specifically captures network connection events on endpoints, including outbound TCP connections, and contains critical fields such as RemoteIP, RemotePort, and Protocol, allowing a security administrator to filter for connections to known malicious IP addresses on non-standard ports like 4444. On the Microsoft 365 Administrator MS-102 exam, this question tests your ability to map a detection requirement to the correct advanced hunting schema, a common scenario for custom detection rules in Microsoft Defender XDR. A frequent trap is confusing DeviceNetworkEvents with DeviceEvents, which logs broader system-level actions but lacks the granular network connection details needed here. For a memory tip, think of the table name literally: DeviceNetworkEvents is your go-to for any network-level event, so when you see “connection,” “IP,” or “port” in the requirement, you know to query this table.
MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
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.
A security administrator wants to create a custom detection rule in Microsoft Defender XDR that alerts when a device initiates an outbound TCP connection to a known malicious IP address on a non-standard port (e.g., port 4444). Which advanced hunting table should be queried to find these network connections?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DeviceNetworkEvents
DeviceNetworkEvents is the correct table because it specifically captures network connection events, including outbound TCP connections to IP addresses and ports. This table contains fields like RemoteIP, RemotePort, and Protocol, making it ideal for detecting connections to known malicious IPs on non-standard ports such as 4444.
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.
✓
DeviceNetworkEvents
Why this is correct
This table contains detailed network connection logs, including destination IP, port, and protocol, which is exactly what is needed.

Read the scenario before looking for a memorised answer.
✗
DeviceProcessEvents
Why it's wrong here
This table records process creation events, not network connections.
✗
EmailEvents
Why it's wrong here
This table stores email-related metadata, not device network activity.
✗
IdentityLogonEvents
Why it's wrong here
This table logs user logon events to Azure AD or on-premises, not network connections from devices.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse DeviceProcessEvents with network events because processes often initiate network connections, but DeviceProcessEvents does not contain network-level details like remote IP or port, leading to an incorrect choice.
Detailed technical explanation
How to think about this question
DeviceNetworkEvents is part of the Advanced Hunting schema in Microsoft Defender XDR and is populated by the Microsoft Defender for Endpoint sensor, which monitors network activity via the Windows Filtering Platform (WFP). The table includes fields such as ActionType (e.g., 'ConnectionSuccess'), RemoteIP, RemotePort, and Protocol (e.g., 6 for TCP), allowing precise detection rules. In a real-world scenario, an attacker using a reverse shell on port 4444 would generate a DeviceNetworkEvents entry with RemotePort=4444 and Protocol=6, which can be queried with a custom detection rule.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
