Free Palo Alto Networks XSIAM-Engineer Exam Dumps Questions & Answers

A global enterprise is migrating its SIEM functionality to XSIAM. A significant challenge is integrating highly sensitive log data from an isolated, air-gapped network segment into XSIAM for correlation, without directly connecting the air-gapped network to the corporate network or the internet. What is the most robust and secure architectural approach for ingesting this data into XSIAM?

• A.Implement a 'data diode' solution that allows unidirectional data flow from the air-gapped network to a staging area in the corporate network, from where a dedicated XSIAM Data Collector can ingest it.
• B.Periodically copy log files from the air-gapped network to an encrypted USB drive, physically transport it, and manually upload the files to XSIAM via the UI.
• C.Configure a highly restricted firewall rule allowing specific syslog traffic from the air-gapped network's log server directly to the XSIAM Data Collector within the corporate network.
• D.Establish a secure VPN tunnel directly from the air-gapped network segment to the XSIAM cloud instance.
• E.Utilize a custom-developed middleware on the air-gapped network to push logs to an intermediate, corporate-network-connected server, which then forwards to XSIAM.

An XSIAM tenant has configured a detection rule to identify 'Lateral Movement via PowerShell Remoting'. This rule has a base score of 70. They also have two scoring rules: 1. Scoring Rule A: Condition: = 'DMZ'' and 'alert.destination_zone = 'Internal_Servers''. Action: Additive Score Change: +20. Order: 10.2. Scoring Rule B: Condition: 'alert.process_name contains 'powershell.exe" and = 'service_account''. Action: Multiplicative Score Change: x0.8. Order: 20. If an alert is generated by the 'Lateral Movement via PowerShell Remoting' rule from a source in 'DMZ' to a 'Internal_Servers' destination, where the process is 'powershell.exe' and the user is a 'service_account', what is the final score of this alert? Assume the XSIAM score is capped at 100 and cannot go below 0.

• A.70
• B.80
• C.90
• D.75
• E.72

A financial institution is implementing Cortex XSIAM and has a very stringent data residency policy, requiring all sensitive log data to remain within a specific geographical region. They are planning to deploy multiple Broker VMs. Which architectural considerations and data flow principles must be strictly adhered to regarding Broker VM placement and configuration to ensure compliance with this data residency requirement?

• A.Configure the Broker VM to encrypt all data at rest and in transit using customer-managed encryption keys (CMEK) before forwarding to the Cortex XSIAM cloud.
• B.Utilize Cortex XSIAM's built-in data filtering capabilities on the Broker VM to redact sensitive fields before data leaves the regional boundary.
• C.Ensure the Cortex XSIAM tenant itself is provisioned in a data center within the required geographical region, as the Broker VM only acts as a forwarding agent.
• D.Deploy all Broker VMS within the specified geographical region, ensuring that all log sources route data only to these local Broker VMs, regardless of XSIAM tenant location.
• E.Implement a custom script on the Broker VM to store all raw logs locally for a predefined retention period before sending summarized metadata to Cortex XSIAM.

An XSIAM administrator is troubleshooting an issue where a specific set of XDR Agents are failing to connect to the XSIAM cloud after a Broker VM firmware update. Other agents are connecting successfully. The Broker VM's status appears healthy in the XSIAM console, and network connectivity from the affected agents to the Broker VM is confirmed. Which of the following is the MOST likely cause and the first area to investigate on the Broker VM itself?

• A.The Broker VM's internal certificates expired or were corrupted during the firmware update. Review the Broker VM's certificate status and logs for TLS/SSL errors.
• B.The Broker VM's IP address changed after the update, and agents have not updated their configuration. Check the Broker VM's network settings.
• C.The Broker VM's internal proxy settings were cleared, preventing it from reaching the XSIAM cloud. Reconfigure proxy settings on the Broker VM.
• D.The Broker VM's inbound firewall rules were inadvertently reset during the firmware update, blocking agent connections. Verify the Broker VM's firewall configuration.
• E.The XDR Agent version on the affected endpoints is incompatible with the updated Broker VM firmware. Downgrade the Broker VM or upgrade the agents.

An XSIAM engineer is tasked with optimizing an indicator rule that detects suspicious network connections to C2 servers. The current rule uses a static list of known C2 IP addresses. However, new C2s emerge daily, leading to detection gaps. The security team also wants to integrate threat intelligence feeds for real-time updates. What XSIAM features and considerations are paramount for managing this detection rule effectively and aligning with the new requirements?

• A.Switch the indicator rule type from 'Indicator' to 'Behavioral' to automatically detect C2 activity without explicit IP lists.
• B.Configure the XSIAM agent on endpoints to block all outbound connections not explicitly whitelisted, effectively preventing C2 communication.
• C.Leverage XSIAM's External Dynamic Lists (EDLs) or Cortex Data Lake (CDL) for ingesting and referencing real-time threat intelligence feeds containing C2 IPs within the indicator rule's XQL query.
• D.Modify the indicator rule to use an XQL Sin' clause with a large, manually updated list of C2 IPs within the rule definition.
• E.Create a separate 'Automated Playbook' in XSIAM to periodically scan all network logs for C2 IPs from an external source.
