XSOAR-Engineer Exam Results

STIX/TAXII are industry-standard protocols for structured threat intelligence exchange. According to the Threat Intelligence section of the XSOAR documentation, TAXII servers and clients provide automated bidirectional sharing using STIX objects, supporting both ingestion and distribution of indicators, observables, relationships, and threat objects.

The TAXII Server content pack specifically enables an organization to expose its threat intelligence via a TAXII 2.0/2.1 compliant endpoint, where the transmitted data is formatted as STIX, making it the correct choice for sharing structured intelligence externally.

The Generic Export Indicators Service pack supports indicator export, but not in STIX format—it exports simple CSV, JSON, or list-based formats. MISP Server supports STIX ingestion and export but is considered a MISP-specific implementation and not the generic STIX distribution mechanism expected in the question. External dynamic lists are not related to STIX or TAXII at all.

Thus, the correct answer is D, as only the TAXII Server pack is designed explicitly for STIX-formatted intelligence sharing.

The XSOAR event-to-incident pipeline is clearly defined in the admin documentation:Ingestion → Classification → Pre-Processing → Incident Creation → Playbook Execution. Classification must occurbeforepre-process rules because the system must determine an incident type (or classification result) before evaluating any pre-process logic that may drop, merge, link, or modify the incoming incident.

Pre-process rules use fields created during the classification stage—including incident type, normalized values, and extracted fields—to determine whether an incident should be suppressed, modified, or related to an existing incident. Without classification completing first, the rule engine would not have the necessary structured data.

Mapping, which transforms raw event fields into incident fields, occursafterclassification but during incident creation, meaning it also precedes playbook execution but not pre-process evaluation.

Therefore, optionD (Classification)is the only correct prerequisite. Pre-process rules cannot run at ingestion time (option C). Playbook execution (option B) happensafterthe incident is created. Mapping (option A) is not a prerequisite for pre-process rules.
