XSIAM-Analyst exam questions

1. Question 1

   Single answer

   During an investigation of an alert with a completed playbook, it is determined that no indicators exist from the email "indicator@test.com" in the Key Assets & Artifacts tab of the parent incident. Which command will determine if Cortex XSIAM has been configured to extract indicators as expected?

   • A

     IcreateNewIndicator value="indicator@test.com"

   • B

     !extractIndicators text="indicator@test.com" auto-extract=inline

   • C

     !checkIndicatorExtraction text="indicator@test.com"

   • D

     Iemailvalue="indicator@test.com"

   Reveal answer

   Correct answer

   • C

     !checkIndicatorExtraction text="indicator@test.com"

   Explanation

   The correct answer is C, the !checkIndicatorExtraction text="indicator@test.com" command.

   This command specifically verifies if Cortex XSIAM has been correctly configured to extract indicators from given text. It ensures that the text provided ("indicator@test.com") would indeed be recognized and extracted as an indicator under the current configuration of Cortex XSIAM.

   Other provided commands do not directly verify the indicator extraction configuration:

   Option A: IcreateNewIndicator manually creates an indicator; it does not validate extraction capability.

   Option B: !extractIndicators attempts extraction immediately but does not verify existing configuration explicitly.

   Option D: Iemailvalue command is generally for creating or querying email indicators, not verifying extraction configuration.

   Therefore, the explicit functionality for checking if indicator extraction is configured correctly within Cortex XSIAM is precisely covered by !checkIndicatorExtraction.

   Reference Extract from Official Document:

   "Verify if Cortex XSIAM is correctly configured to extract indicators using the command !checkIndicatorExtraction text=."

   This exact description confirms that option C is the correct answer to validate the configuration explicitly.

2. Question 2

   Multiple answer

   Which two actions will allow a security analyst to review updated commands from the core pack and interpret the results without altering the incident audit? (Choose two)

   • A

     Run the core commands directly from the playground and invite other collaborators.

   • B

     Run the core commands directly from the Command and Scripts menu inside playground

   • C

     Create a playbook with the commands and run it from within the War Room

   • D

     Run the core commands directly by typing them into the playground CLI.

   Reveal answer

   Correct answer

   • B

     Run the core commands directly from the Command and Scripts menu inside playground

   • D

     Run the core commands directly by typing them into the playground CLI.

   Explanation

   Correct answers are B and D.

   In Cortex XSIAM/XSOAR, the playground provides a safe environment for testing commands without modifying the incident audit log or impacting live incidents.

   Option B: Running commands from the "Command and Scripts" menu within the playground allows review and interpretation of command outputs safely and isolated from actual incidents.

   Option D: Typing commands directly into the playground CLI similarly enables secure review and interpretation of results without affecting the incident audit or live data.

   Options A and C are incorrect because:

   Option A invites collaboration, potentially impacting visibility or causing accidental changes.

   Option C creates playbooks that execute directly within the War Room, thus interacting with real incidents.

3. Question 3

   Single answer

   An analyst is responding to a critical incident involving a potential ransomware attack. The analyst immediately initiates full isolation on the compromised endpoint using Cortex XSIAM to prevent the malware from spreading across the network. However, the analyst now needs to collect additional forensic evidence from the isolated machine, including memory dumps and disk images without reconnecting it to the network. Which action will allow the analyst to collect the required forensic evidence while ensuring the endpoint remains fully isolated?

   • A

     Using the endpoint isolation feature to create a secure tunnel for evidence collection

   • B

     Collecting the evidence manually through the agent by accessing the machine directly and running "Generate Support File"

   • C

     Using the management console to remotely run a predefined forensic playbook on the associated alert

   • D

     Disabling full isolation temporarily to allow forensic tools to communicate with the endpoint

   Reveal answer

   Correct answer

   • B

     Collecting the evidence manually through the agent by accessing the machine directly and running "Generate Support File"

   Explanation

   The correct answer is B, Collecting the evidence manually through the agent by accessing the machine directly and running "Generate Support File".

   In situations where full isolation is enabled on an endpoint, all network communication is completely restricted. To ensure that the endpoint remains isolated while still obtaining forensic evidence such as memory dumps or disk images, the analyst needs to use manual collection via the agent directly on the machine. The "Generate Support File" feature within the agent allows analysts to locally gather detailed forensic data without breaking network isolation.

   This manual method ensures the endpoint does not reconnect or communicate externally, maintaining strict isolation for security purposes.

   "In endpoint isolation mode, network communication is completely blocked. Analysts should utilize the local 'Generate Support File' function on the agent to collect forensic data while maintaining full isolation."

5. Question 4

   Multiple answer

   Which two statements apply to IOC rules? (Choose two)

   • A

     They can be used to detect a specific registry key.

   • B

     They can have an expiration date of up to 180 days.

   • C

     They can be excluded using suppression rules but not alert exclusions.

   • D

     They can be uploaded using REST API.

   Reveal answer

   Correct answer

   • A

     They can be used to detect a specific registry key.

   • D

     They can be uploaded using REST API.

   Explanation

   Correct answers are A and D.

   Option A (Correct): IOC rules within Cortex XSIAM can detect specific indicators such as files, registry keys, IP addresses, hashes, and URLs.

   Option D (Correct): IOC rules can indeed be uploaded or updated programmatically using REST APIs, enabling automation and bulk management.

   Options B and C are incorrect due to the following reasons:

   Expiration dates for IOC rules vary depending on system settings, and there is no strict 180-day limit explicitly defined in the provided documentation.

   IOC rules are managed through general alert exclusion mechanisms as well as through suppression rules.

   "IOC rules can detect specific files, hashes, registry keys, IP addresses, and URLs and can be managed programmatically via REST API."

6. Question 5

   Single answer

   Which configuration will ensure any alert involving a specific critical asset will always receive a score of 100?

   • A

     An asset as critical in Asset Inventory

   • B

     SmartScore to apply the specific score to the critical asset

   • C

     A user scoring rule for the critical asset

   • D

     A risk scoring policy for the critical asset

   Reveal answer

   Correct answer

   • D

     A risk scoring policy for the critical asset

   Explanation

   The correct answer is D, a risk scoring policy for the critical asset.

   In Cortex XSIAM, to consistently apply a high score (e.g., 100) to any alert involving a particular asset, analysts should define and apply a risk scoring policy. Such policies allow organizations to specifically customize and enforce a scoring framework to reflect the critical nature of certain assets, ensuring they are always prioritized during incident response activities.

   Asset criticality alone (option A) doesn't automatically assign a static high score to every alert.

   SmartScore (option B) is AI-driven and dynamic; it cannot guarantee a fixed, always-maximized score.

   User scoring rules (option C) target user entities, not specifically the assets themselves.

   "Risk scoring policies are explicitly defined to consistently assign specific scores to incidents or alerts involving critical assets, ensuring prioritized visibility in the incident queue."
