  1. 51.A security operations center (SOC) is onboarding a new threat intelligence feed into Cortex XSOAR. The feed provides indicators of compromise (IOCs) such as IP addresses, domains, and file hashes via an API endpoint that returns a list of new IOCs every 5 minutes. The SOC needs these IOCs to be automatically ingested into XSOAR and enriched. Which integration type is BEST suited for this scenario?Integrations
  2. 52.A security engineer is developing a custom integration in Cortex XSOAR that needs to perform pagination for an API endpoint returning a large dataset. The API uses a `next_page_token` in the response body to indicate if more data is available and to fetch the subsequent page. Which of the following approaches is the MOST effective for implementing this pagination logic within the custom integration's fetch or command functions?Integrations
  3. 53.A security analyst is investigating a suspected data exfiltration incident. During the investigation, they discover a previously unknown IP address that is communicating with several internal hosts. This IP address is not currently tracked as an indicator of compromise (IOC) in any existing threat intelligence feeds. The analyst needs to quickly add this IP address to the incident as a new, ad-hoc observable for enrichment and future tracking. How can they achieve this most efficiently in Cortex XSOAR?Incident Management
  4. 54.A security engineer is developing a custom integration for Cortex XSOAR that interacts with a network device. The device's API returns large amounts of data in its responses, and the engineer wants to ensure that the raw JSON output from a specific command is always preserved in the War Room for forensic analysis, even if the integration's `return_outputs()` function only extracts a subset of the fields. Which `CommandResults` parameter should be used to achieve this?Integrations
  5. 55.A security engineer is developing a custom integration in Cortex XSOAR that interacts with a legacy system's API.

The engineer needs to ensure this header is consistently included in all API calls made by the integration. Where is the most appropriate place to define this custom header within the Python integration code?Integrations
  6. 56.A security analyst is investigating an incident where a user's credentials were compromised. During the investigation, they discover that the same user account has triggered similar alerts across three different systems (endpoint, email, and identity provider) within a 24-hour window. The analyst wants these three separate alerts, currently individual incidents, to be consolidated into a single, comprehensive incident for easier tracking and remediation. Which XSOAR capability would achieve this consolidation?Incident Management
  7. 57.A security operations team is onboarding a new threat intelligence feed into Cortex XSOAR. The feed provides indicators of compromise (IOCs) such as malicious IP addresses and URLs.

How should the analyst configure this in the integration to allow for easy updates without modifying the integration code?Integrations
  18. 68.A security analyst is troubleshooting a custom integration where a specific command, `get-indicator-details`, sometimes takes a very long time to complete due to the external API's latency. Other commands in the same integration are fast. The analyst wants to prevent XSOAR from prematurely terminating *only* this slow command while allowing other commands to use default timeouts. How can this be achieved?Integrations

  22. 72.An incident responder is reviewing an integration's configuration within Cortex XSOAR. The integration, which fetches incidents from an external EDR platform, has a 'Fetch incidents' checkbox enabled and a 'Last Run' timestamp that is several hours old, despite new incidents being reported in the EDR platform. The responder needs to quickly identify if the issue is with the integration's ability to pull new data or with its schedule. Which specific integration configuration parameter should the responder inspect first to diagnose the scheduling aspect?Integrations
  23. 73.A security analyst is developing a custom integration in Cortex XSOAR to block malicious IPs on a firewall via its API. The firewall API expects IP addresses in CIDR notation (e.g., '192.168.1.0/24'). However, the incident context in XSOAR might contain IPs as single addresses (e.g., '10.0.0.1'). The integration needs to convert single IPs to their /32 CIDR equivalent before sending them to the firewall. Which XSOAR utility function or common Python library is best suited for this IP manipulation within the integration code?Integrations
  24. 74.A security analyst is troubleshooting an integration that intermittently fails to fetch incidents.
