A critical zero-day vulnerability has been disclosed, and the XSIAM team needs to rapidly deploy a new detection rule. Due to the high potential impact, all alerts generated by this rule must immediately be prioritized and assigned the highest possible score, regardless of other contextual factors. Which XSIAM scoring rule configuration element is explicitly designed to achieve this immediate, overriding effect?

• A.Utilizing the 'Set Total Score' action in a scoring rule, ensuring it's evaluated with a high 'Order' and the target score is the maximum allowed (e.g., 100).
• B.Setting the 'Condition' of the scoring rule to 'always true' and the 'Score Modification Type' to 'Additive' with a high value.
• C.Configuring the 'Rule Weight' within the detection rule itself to its maximum value.
• D.Applying a 'Multiplicative' score modification with a factor of 10 to any alert from this rule.
• E.Disabling all other scoring rules that might affect alerts generated by this new rule.

A large enterprise, 'GlobalCorp', is planning to integrate Palo Alto Networks XSIAM. During the initial infrastructure evaluation, their security team discovers a significant portion of their existing endpoint fleet consists of Windows Server 2008 R2 and CentOS 6.x systems. Additionally, they rely heavily on legacy SIEM solutions and on-premise Active Directory. What are the PRIMARY challenges GlobalCorp faces in aligning their current infrastructure with XSIAM's architectural requirements, and what is the MOST critical immediate action they should consider?

• A.The primary challenge is the lack of native XDR agent support for their outdated OS versions. The most critical immediate action is to initiate an OS upgrade/replacement project for non-compliant systems to ensure comprehensive endpoint telemetry collection.
• B.The primary challenge is managing user identities across multiple systems. The most critical immediate action is to integrate XSIAM with their existing on-premise Active Directory using LDAP for user authentication.
• C.The primary challenge is network latency between their data centers and the XSIAM cloud. The most critical immediate action is to implement dedicated MPLS connections to the nearest XSIAM cloud region.
• D.The primary challenge is integrating XSIAM with their legacy SIEM. The most critical immediate action is to configure API gateways for data forwarding from the legacy SIEM to XSIAM.
• E.The primary challenge is the data ingestion volume from on-premise Active Directory. The most critical immediate action is to deploy XSIAM Data Collectors on-premise and configure them for Active Directory replication.

An internal audit identified a gap in detecting privilege escalation attempts using Windows built-in tools like 'seclogon.exe' (RunAs) or psexec.exe' (Sysinternals) when used by non-administrative users. These tools are legitimate but often abused. The goal is to detect Process.Name' 'seclogon.exe' or 'psexec.exe' being invoked from a standard user context, especially when followed by an attempt to execute a sensitive command on another system or elevate privileges locally. Which XQL query would effectively capture this behavior as a BIOC, minimizing false positives from legitimate IT operations?

• A.
• B.
• C.
• D.
• E.

A critical component of XSIAM Engine installation involves secure communication. After deploying an XSIAM Engine, an administrator attempts to register it with the XSIAM cloud tenant but encounters an 'SSL/TLS handshake failed' error. Which of the following are the most probable causes for this error, and how should the administrator troubleshoot it?

• A.All of the above.
• B.The Engine's time is significantly out of sync with the NTP server, causing certificate validation issues. Troubleshoot by verifying NTP synchronization.
• C.The Engine's outbound firewall is blocking HTTPS (port 443) traffic to the XSIAM cloud FQDNs. Troubleshoot by checking firewall rules and performing a
• D.An untrusted or expired Root CA certificate for the XSIAM cloud is missing from the Engine's trust store. Troubleshoot by verifying and importing necessary certificates.
• E.The XSIAM cloud tenant is experiencing an outage. Troubleshoot by checking the Palo Alto Networks status page.

You are troubleshooting a scenario where a large number of XSIAM agents suddenly report 'Disconnected' status. Upon reviewing the XSIAM audit logs, you notice a recent entry indicating a change to the 'Agent Deployment Profile' named 'Default-Profile', specifically 'Removed: Collector IP Address X.X.X.X'. However, this IP address is still valid and reachable. Which of the following is the most likely reason for the widespread agent disconnection?

• A.An administrator inadvertently removed a primary or active collector IP from the 'Default-Profile', causing agents to lose their primary connection target.
• B.The 'Removed: Collector IP Address' entry indicates that this specific collector was deprecated and agents are trying to connect to it.
• C.A new Agent Deployment Profile was assigned to all affected agents, and the 'Default-Profile' changes are irrelevant.
• D.The XSIAM tenant's public IP address range for collector endpoints has changed, and agents are trying to connect to an outdated, removed entry in their profile.
• E.The agents received an 'empty' profile update due to a network glitch, causing them to lose all configuration.
