SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. 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 analyst needs to connect a Palo Alto Networks firewall to Microsoft Sentinel to ingest logs. The firewall supports Syslog and Common Event Format (CEF). Which data connector should the analyst use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Palo Alto Networks (via Syslog CEF)
The Palo Alto Networks firewall supports sending logs in Common Event Format (CEF) over Syslog, and Microsoft Sentinel provides a dedicated data connector specifically for Palo Alto Networks (via Syslog CEF). This connector parses the CEF-formatted syslog messages using a Log Analytics agent or AMA, normalizing fields into the CommonSecurityLog table for seamless ingestion. Using the vendor-specific connector ensures proper field mapping and schema alignment, unlike a generic CEF connector which may not handle Palo Alto's specific CEF extensions correctly.
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.
✓
Palo Alto Networks (via Syslog CEF)
Why this is correct
This connector is pre-built to ingest Palo Alto firewall logs formatted in CEF over Syslog.

Read the scenario before looking for a memorised answer.
✗
Common Event Format (CEF) via Syslog (generic)
Why it's wrong here
While it can work, the specific Palo Alto connector provides easier setup and better field mapping.
✗
Syslog (without CEF)
Why it's wrong here
Syslog without CEF would lose the structured fields and require custom parsing, making it less suitable.
✗
Custom Text Logs
Why it's wrong here
Custom Text Logs would require manual definition of the log format and are not optimized for Palo Alto CEF.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the distinction between vendor-specific connectors and generic connectors, trapping candidates who assume any CEF-capable device can use the generic CEF connector without considering the need for vendor-specific field mappings and schema compatibility.
Detailed technical explanation
How to think about this question
CEF is an open logging format defined by ArcSight (now Micro Focus) that uses a key-value pair structure within syslog messages, with a header containing device vendor, product, version, and signature ID. The Palo Alto Networks CEF connector in Sentinel maps specific CEF extension keys (e.g., 'src', 'dst', 'duser') to the CommonSecurityLog schema, enabling out-of-the-box analytics rules and workbooks. In a real-world scenario, using the generic CEF connector might fail to populate fields like 'ExternalID' or 'DeviceCustomString1' that Palo Alto uses for threat IDs, causing detection gaps.

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 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.
