Authentic Paloalto Networks Certification Exam XSIAM-Analyst Questions Answers

The correct answer isA – Isolate Endpoint.

The most effective initial response to contain a breach and reduce attacker mobility is toisolate the endpoint. This action ensures that the compromised machine can no longer communicate with the network or external systems, effectively cutting off lateral movement and exfiltration by attackers, while still allowing controlled response operations.

"Isolate Endpoint is the primary response action used to immediately contain a threat by severing all network communication, thus limiting attacker movement during active incidents."

The correct answer isA– the query using the fieldcausality_actor_effective_username.

When analyzing events where privilege escalation is used, it is essential to identify the original effective user that initiated the causality chain, not merely the process’s own running user (as provided by other fields). The fieldcausality_actor_effective_usernamespecifically provides the effective username context of the actor behind the entire chain of actions that resulted in launching the suspicious executable.

Explanation of fields from Official Document:

causality_actor_effective_username: This field indicates the original effective user who started the entire causality chain.

actor_process_usernameandaction_process_username: These fields indicate the immediate process username, not necessarily reflecting the correct original context when privilege escalation occurs.

Therefore, to always identify the correct user context in privilege escalation scenarios, optionAis the verified correct answer.

The correct answer isA – The rule is configured with alert severity below Medium.

By default, in Cortex XSIAM,only alerts with a severity of Medium or higher will automatically generate incidents. If a correlation rule creates alerts with severity set below Medium (such as Low or Informational), these alerts willnotresult in the automatic creation of an incident. This ensures that incident queues are not filled with low-priority events.

"Incidents are generated only for alerts with severity of Medium or higher. Alerts below this threshold will not automatically create incidents."
