  1. 101.A security analyst is developing a custom integration that interacts with an internal security tool. This tool requires all API requests to be signed using a private key and a specific hashing algorithm (e.g., HMAC-SHA256). The private key is stored securely in the integration's configuration. What type of authentication mechanism is the integration primarily implementing?Integrations
  2. 102.A security engineer is developing a custom integration for Cortex XSOAR that interacts with a partner's API. The partner's API requires specific configuration parameters, such as a partner ID and a shared secret, which are unique to each customer and should be easily configurable by end-users without modifying the integration code. How should these parameters be defined within the integration's `yml` file to allow for user configuration through the XSOAR UI?Integrations
  3. 103.A cybersecurity firm is developing a custom integration for Cortex XSOAR. The integration needs to securely store sensitive configuration data (e.g., client IDs, tenant IDs) that are not API keys or credentials, but still require protection from unauthorized viewing. Which of the following methods is the MOST appropriate for storing such data within the integration's configuration parameters?Integrations
  4. 104.A security operations center (SOC) manager is evaluating Cortex XSOAR deployment options. The manager's primary concern is to ensure that the platform can scale to handle a rapidly increasing volume of security incidents and integrations without significant downtime during upgrades or component failures. Which Cortex XSOAR architecture component is primarily responsible for distributing the workload and ensuring continuous operation in such a scenario?Cortex XSOAR Fundamentals
  5. 105.A security engineer is developing a custom integration for Cortex XSOAR that needs to retrieve a large volume of historical logs from an external SIEM. The SIEM's API implements cursor-based pagination, where each response includes a `next_cursor` value that must be sent in the subsequent request to fetch the next batch of logs. How should the integration manage this `next_cursor` value to retrieve all pages of data?Integrations
  6. 106.A security analyst is troubleshooting a custom integration that is failing to connect to a partner's API. The partner uses a self-signed SSL certificate, and the integration logs show `SSL_CERTIFICATE_VERIFY_FAILED` errors. The analyst confirms that the self-signed certificate is valid but not trusted by default. Which integration instance setting should be enabled to allow the integration to connect to the partner's API without compromising the security of other connections?Integrations
  7. 107.A security engineer is developing a custom integration for Cortex XSOAR. The integration needs to perform a series of operations that might take several minutes to complete, such as querying a large database or initiating a long-running scan. The engineer wants to ensure that the integration's output (results, errors) from these potentially long operations is reliably captured and displayed in the War Room, even if the connection to the XSOAR server is temporarily lost or the integration container restarts. Which `demisto` function should be used to ensure persistent output capture?Integrations
  8. 108.A security analyst is developing a custom integration for Cortex XSOAR that interacts with a legacy SOAP API.

  11. 111.A SOC engineer is building a custom integration that interacts with a threat intelligence platform. The platform's API returns a large JSON object containing various indicators, but for the War Room, only a subset of specific indicator types and their values are relevant. How should the `return_results()` function be used to display only the necessary information clearly in the War Room?Integrations

How should the integration store and retrieve this unique identifier to ensure it's available for later commands within the same incident context?Integrations
  16. 116.A security engineer is developing a custom integration in Cortex XSOAR that interacts with a legacy system. The legacy system's API requires a specific, non-standard authentication header that includes a dynamically generated timestamp and a unique session ID. Which method should the engineer use within the integration code to correctly add this custom authentication header to every API request?Integrations
  17. 117.A security analyst has identified a new type of malware targeting their organization. They want to create a structured approach in Cortex XSOAR to handle future incidents related to this malware, ensuring consistent data collection and automated response steps.

Which of the following should the analyst define FIRST to achieve this?Incident Management
  18. 118.A security analyst is developing a custom integration for Cortex XSOAR that needs to perform a series of actions on an external system. These actions involve multiple API calls that require an authentication token.

What is the most likely reason for this discrepancy?Incident Management
  33. 133.A security administrator needs to configure granular access control for different teams within a single Cortex XSOAR tenant. For example, the 'Threat Intel' team should only be able to view and modify indicators, while the 'Incident Response' team should only view and modify incidents.

How should the integration handle this pagination efficiently to retrieve all events?Integrations
  37. 137.A security team receives numerous alerts daily, but many are false positives or low-priority informational alerts that do not require full incident response.

Which primary function of Cortex XSOAR does this scenario highlight?Cortex XSOAR Fundamentals
  42. 142.A global organization uses Cortex XSOAR to manage incidents, with different teams responsible for different stages of the incident lifecycle. They need to ensure that once an incident moves from the 'Investigation' stage to the 'Containment' stage, only the 'Containment Team' can modify specific containment-related fields, and other teams can only view them. How can this be effectively implemented in Cortex XSOAR?Incident Management
  43. 143.A security team uses Cortex XSOAR to manage incidents. They frequently encounter situations where an alert from their SIEM triggers a new incident, but a few minutes later, a very similar alert from the same source, related to the same entity (e.g., IP address, user), also triggers another incident. They want to automatically group these closely related incidents to avoid redundant investigations. Which XSOAR feature is specifically designed for this purpose?Incident Management
  44. 144.A security analyst is developing a custom integration in Cortex XSOAR that needs to interact with an internal REST API. The API uses a non-standard port (e.g., 8443) and is only accessible from specific network segments. During testing, the integration consistently fails to connect to the API, reporting 'Connection refused' errors. The XSOAR engine's network connectivity to the API server has been verified. What is the most likely cause of this connection issue?Integrations
