XSIAM-Analyst Exam Dumps - Paloalto Networks Certification Questions and 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."

The correct answer isB – To retrieve data either at specific intervals or at a specified time.

Scheduling XQL queries allows analysts and teams toautomate the retrieval of data at regular intervals or specific times(such as daily, hourly, or during set windows), supporting reporting, monitoring, and automation workflows without requiring manual intervention.

"Analysts can schedule XQL queries to automatically retrieve data or generate reports at regular intervals or specified times."

The correct answer isD – The indicator verdict was manually set to Suspicious.

When an indicator's verdict is manually set in Cortex XSIAM, automated reputation scripts and updates do not override this manual setting. Thus, even if the reputation result in the War Room reflects a higher risk (Malicious), the indicator's main verdict will not change until manually updated by an analyst.

"If an indicator’s verdict is set manually, it will not be automatically updated by enrichment or reputation scripts. Manual verdicts must be changed by an analyst."

(Both steps together are needed for accurate configuration: "Filter and select one or more file, IP address, and domain indicators." AND "Select profiles for prevention")

The correct steps are tofilter and select one or more file, IP address, and domain indicators(C) and thenselect profiles for prevention(D).

When configuring an indicator prevention rule in Cortex XSIAM/XDR, after naming the rule and setting its severity, the analyst should:

Filter and select the specific indicators(e.g., file hashes, IP addresses, domains) that are to be blocked or prevented.

Select the appropriate endpoint profiles or groupswhere the rule should be enforced for active prevention.

"Before saving an indicator prevention rule, filter and select the relevant indicators (file, IP address, and domain), then assign the prevention profiles that will enforce the rule on endpoints."

The correct answer isC – <name of field> != null or <field name> != "NA".

Filtering with != null removes records with null values, and != "NA" further removes records that explicitly have "NA" as the value, ensuring the table only displays meaningful results.

"Use filters like != null or != 'NA' in XQL queries to exclude empty or placeholder values from results."

The correct answer isB, 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."

The correct answer isD – The xdm_core fieldset will be returned by default.

In Cortex XSIAM, when no specific fields are selected in a data model query, thexdm_core fieldset(which contains essential, core fields of the dataset) is automatically returned. This ensures analysts always have a baseline set of meaningful information in the results, even when fields are not explicitly specified.

"When no fields are specified in a data model query, Cortex XSIAM defaults to returning the xdm_core fieldset, which contains key metadata and context."

===========

The correct answer isC – An asset attributed to the organization because the Subject Organization field contains the company name.

When determining ownership of assets in the attack surface, attribution based solely on the Subject Organization field containing the company name is considered less reliable than evidence based on domain registration, authoritative DNS relationships, or manual analyst validation. This is because the Subject Organization field may contain non-unique or common names, leading to a higher rate of false associations, and is not as strong as direct registration records or explicit analyst verification.

“The confidence level is lowest when asset attribution is based on the Subject Organization field, since this field may not be unique to the organization and can result in inaccurate mapping.”
