The answer is Microsoft Defender Threat Intelligence and any TAXII 2.0 or 2.1 server. Microsoft Defender Threat Intelligence is a legitimate source because it provides curated, high-fidelity threat indicators directly integrated into the Sentinel platform, while TAXII servers are valid as they use the open-standard STIX/TAXII protocol to ingest structured threat feeds from sources like MITRE ATT&CK or third-party providers. On the SC-200 exam, this question tests your understanding of the built-in data connectors for threat intelligence, specifically the Threat Intelligence - TAXII connector and the Microsoft Defender Threat Intelligence connector, which are the only two native options for ingesting external threat indicators. A common trap is confusing generic web feeds or custom APIs with these standardized connectors, so remember that Sentinel requires either a TAXII-compliant server or Microsoft’s own threat intelligence feed. Memory tip: think “TAXII and Microsoft” as the only two official ingestion paths for threat intelligence in Sentinel.
SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. 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.
Which TWO are legitimate sources of threat intelligence that can be ingested into Microsoft Sentinel?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
STIX/TAXII threat intelligence feeds
A is correct because STIX/TAXII is an open-source standard for sharing cyber threat intelligence (CTI). Microsoft Sentinel can ingest threat indicators from any TAXII 2.0 or 2.1 server using the built-in Threat Intelligence - TAXII data connector, allowing organizations to consume structured threat feeds (e.g., from MITRE ATT&CK or third-party providers) directly into Sentinel for correlation and alerting.
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.
✓
STIX/TAXII threat intelligence feeds
Why this is correct
Sentinel supports ingesting TI from STIX/TAXII servers.

✓
Microsoft Defender Threat Intelligence
Why this is correct
It provides high-fidelity TI that can be ingested via API or connectors.

✗
Exchange Online Protection
Why it's wrong here
EOP is an email filtering service, not a TI source.
✗
Microsoft Intune
Why it's wrong here
Intune is a mobile device management service, not a threat intelligence source.
✗
Microsoft Purview Compliance Manager
Why it's wrong here
Purview is for compliance and governance, not threat intelligence.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse security management tools (like EOP, Intune, or Compliance Manager) with actual threat intelligence sources, assuming any Microsoft security product can be a threat feed, whereas only dedicated CTI platforms or feeds (STIX/TAXII, Microsoft Defender Threat Intelligence) provide structured indicator ingestion.
Detailed technical explanation
How to think about this question
STIX (Structured Threat Information Expression) defines a standardized JSON schema for representing cyber threat indicators (e.g., IPs, domains, hashes), while TAXII (Trusted Automated Exchange of Intelligence Information) is the transport protocol (HTTP-based API) for exchanging STIX packages. Sentinel’s TAXII connector supports both polling (collection-based) and push (channel-based) ingestion, and each ingested indicator is stored in the ThreatIntelligenceIndicator table, enabling automated correlation with logs from other data sources.

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.
