A security team is implementing a SOAR playbook to automatically enrich Microsoft Sentinel AI security incidents with threat intelligence. When a new incident is created involving an external IP address, the playbook should look up the IP in Microsoft Defender Threat Intelligence (MDTI) and add the result as a comment to the Sentinel incident. Which Logic Apps connector enables the MDTI lookup?

A is correct because this requires two steps in the playbook: (1) calling the Microsoft Defender Threat Intelligence (MDTI) REST API via the Logic Apps HTTP connector (or the MDTI-specific connector if available) to look up the IP and get its reputation/context, and (2) using the Microsoft Sentinel connector's 'Add comment to incident' action to write the enrichment data back to the incident. This combination of the HTTP connector for external API calls and the Sentinel connector for incident updates is the standard pattern. B is wrong because the Microsoft Graph Security API provides access to security alerts and incidents across Microsoft products but does not serve as a direct Threat Intelligence lookup interface for IP enrichment in the same way. C is wrong because Azure Monitor is for log analytics queries; it does not provide threat intelligence enrichment. D is wrong because the Defender for Endpoint connector provides endpoint management actions, not general threat intelligence IP reputation lookup.
