   A security operations team has completed the migration of its detection rules and automation playbooks from a legacy SIEM to Cortex XSIAM. The team members who will now manage the system were not part of the migration project. What is the most important action to ensure the long-term success of the migration?

   • AConducting comprehensive documentation and knowledge transfer sessions for the operational team.
   • BDecommissioning the legacy SIEM immediately to force the team to use XSIAM.
   • CCreating a new set of detection rules from scratch in XSIAM to replace the migrated ones.
   • DRestricting access to XSIAM to only the team members who performed the migration.

   • BTo ensure the playbook produces equivalent response actions and logic
   • CTo minimize the number of steps in the playbook
   • DTo replicate the exact same code and syntax used in the legacy system

   What is the primary goal of assessing existing automation use cases from a legacy SIEM during a migration to Cortex XSIAM?

   • ATo identify which use cases are no longer needed and can be retired
   • BTo prioritize use cases based on the number of alerts they generate
   • CTo determine which use cases can be directly replicated in XSIAM without changes
   • DTo evaluate the applicability of each use case and identify necessary adaptations for XSIAM
