Palo Alto Networks XSIAM Engineer Sample Questions (Q176-Q181):NEW QUESTION # 176
An XSIAM engineer is investigating a persistent alert from an indicator rule that flags 'attempts to modify critical system files.' The rule's current XQL is:

After analysis, it's determined that legitimate patching and antivirus updates are triggering these alerts. How should the engineer refine this rule to eliminate these false positives while preserving detection of malicious activity?
  • A. Modify the XQL to include a check for the 'digital_signature' of the process performing the write, ensuring it's not signed by Microsoft or the organization's trusted vendors, specifically for update/patch processes.
  • B. Add 'and not (process_name in ('msiexec.exe', 'wusa.exe') and parent_process_name = ' Trustedlnstaller.exe')' to the XQL query.
  • C. Filter by and exclude 'SYSTEM' user, as legitimate updates often run as SYSTEM.
  • D. Change the 'file_path' to only look for executable files with a .exe' extension, ignoring DLLs.
  • E. Remove the rule, as critical system file modification is too noisy to reliably detect with indicator rules.
Answer: A
Explanation:
Option C is the most effective and robust solution for handling legitimate updates. Digital Signatures: Legitimate patching and antivirus updates are almost always performed by digitally signed executables from trusted vendors (like Microsoft for OS updates, or a reputable AV vendor). By filtering based on the absence of a valid, trusted digital signature, you can effectively distinguish legitimate updates from malicious attempts to modify system files. This is a high-fidelity filter. Option A is a surrender. Option B is a partial solution, as patchers and installers can use various processes and parent processes, and 'Trustedlnstaller.exe' might not always be the direct parent, also it's often more reliable to use signatures. Option D would eliminate many legitimate updates, as SYSTEM often performs these, and also miss malicious activity by SYSTEM. Option E would completely miss malicious modifications to critical DLLS, which is a common technique.

NEW QUESTION # 177
A newly installed Cortex XSIAM Engine consistently fails to onboard new endpoints, reporting 'Agent connection failed: certificate validation error' in the Engine's logs. Existing, previously onboarded endpoints continue to communicate successfully. Further investigation reveals that the XSIAM tenant was recently updated to a newer version, and the XSIAM Engine itself passed its health checks after the update. What is the most likely root cause, and how would you resolve it?
  • A. The XSIAM Engine has run out of disk space, preventing it from processing new agent connections. Clear disk space on the Engine.
  • B. There is a firewall blocking communication on port 443 between the new endpoints and the XSIAM Engine. Check firewall rules.
  • C. The XSIAM cloud tenant's certificates were updated during the tenant upgrade, and the newly deployed XSIAM Engine (or new agents) are not trusting the new certificate chain. The existing agents might have cached the old certificates. Resolution involves ensuring the new agent deployments and the XSIAM Engine have the updated trust store information, potentially by re-downloading the agent installer or verifying Engine configuration.
  • D. The XSIAM Engine's local clock is significantly out of sync, causing its own certificate to appear invalid to new agents. Resynchronize the Engine's NTP.
  • E. The existing agents are using an older, unsupported protocol version that is incompatible with the updated XSIAM Engine.
Answer: C
Explanation:
The key phrase here is 'existing, previously onboarded endpoints continue to communicate successfully' while 'newly installed' endpoints fail with a certificate validation error after a 'tenant was recently updated'. This strongly suggests a certificate mismatch related to the tenant's update. When a Cortex XSIAM tenant is updated, it's possible that the certificates used for agent onboarding and communication are also updated. Existing agents might have already trusted the previous certificate chain, while new agents, encountering the new certificates, fail validation if their trust store isn't updated or if there's a misconfiguration in how the new certificate is presented. The XSIAM Engine itself might also need to explicitly trust the new tenant certificates. Option A is a possibility, but less likely to affect only new agents. Option C would affect all agents, not just new ones. Option D would manifest as other errors (e.g., storage full). Option E is less likely, as protocol versions are generally backward- compatible or explicitly announced as breaking changes, and the error specifically mentions certificate validation, not protocol. Therefore, certificate chain updates related to the tenant upgrade are the most plausible cause.

NEW QUESTION # 178
An advanced XSIAM dashboard is required to analyze 'Lateral Movement' attempts, specifically focusing on RDP connections originating from non-standard internal subnets to critical servers. The dashboard should display: 1) Source IP, 2) Destination IP, 3) User, and 4) Connection time, for all such detected attempts. Additionally, it must provide a 'risk score' for each connection based on a custom lookup table of 'known risky internal IPs'. Which combination of XQL, lookup, and visualization would yield the most insightful dashboard?
  • A.
  • B.
  • C. Manual parsing of RDP logs from endpoints and correlating them in a spreadsheet.
  • D. Use a pre-built 'Lateral Movement' widget, as custom risk scoring is not feasible.
  • E.
Answer: B
Explanation:


NEW QUESTION # 179
A large enterprise uses XSIAM for comprehensive security. They have a strict policy against the use of insecure authentication protocols like NTLMv1 , even for internal services. They want to create an ASM rule to detect any internal server or application attempting to authenticate using NTLMv1. Given that XSIAM collects authentication logs from various sources (Active Directory, Linux authentication, network authentications), which of the following XQL approaches would be most effective for detecting NTLMv1 usage across their distributed environment?
  • A.
  • B.
  • C. Combine insights from 'xdr_authentication_logs' (for protocol details) and 'xdr_network_sessions' (for application protocol and potential deep packet inspection insights if available) to precisely identify NTLMv1. An example would be:
  • D.
  • E.
Answer: C
Explanation:
Option E is the most comprehensive and effective approach for detecting NTLMv1 across a distributed environment in XSIAM. It leverages the 'union' operator to combine data from different relevant datasets. is ideal for explicit authentication protocol details, while can provide insights from network-level detections (like deep packet inspection signatures if available for NTLMv1 or related SMBv1 traffic, which often implies NTLMv1 usage). This multi-source correlation provides a more robust and complete picture. Option A is too broad and inefficient. Option B assumes a specific 'authentication_version' field, which might not be uniformly present across all authentication logs. Option C relies solely on a specific network signature, which might not always fire or be available for all NTLMv1 scenarios. Option D focuses only on failures and might miss successful NTLMv1 authentications.

NEW QUESTION # 180
A large-scale XSIAM deployment is experiencing significant delays (hours) in log visibility from geographically dispersed Palo Alto Networks NGFWs, despite network connectivity being verified and NGFWs showing active log forwarding. The and metrics on the XSIAM Collectors indicate high activity, but is significantly lower. This suggests a bottleneck. Which of the following is the most effective immediate action to identify the specific bottleneck within the XSIAM data ingestion pipeline?
  • A. Check the XSIAM Data Lake's disk I/O performance and free space. While important, the metrics provided being low while is high) point to a pre-storage processing bottleneck.
  • B. Temporarily disable all custom parsing rules and normalization rules for the affected data sources to see if performance improves. This helps isolate if custom logic is the bottleneck, but is disruptive.
  • C. Deploy additional XSIAM Collectors to distribute the load. This is a scaling solution, not an immediate troubleshooting step to identify the bottleneck.
  • D. Increase the CPU and memory allocated to the XSIAM Collectors. This is a potential solution, but not an immediate identification of the specific bottleneck.
  • E. Review the XSIAM Collector's 'collector.log' and 'pipeline.log' for errors or warnings related to parsing failures, unhandled events, or persistent backlogs in specific processing stages. Look for repeated messages indicating a slow parser or a problematic data source.
Answer: E
Explanation:
When lags significantly behind and is high, it points to a bottleneck within the collector's processing pipeline (parsing, normalization, enrichment) rather than just network ingress or data lake writes. Option B is the most effective immediate troubleshooting step because it directs the engineer to internal collector logs, which provide granular insights into where processing is stalling or failing. Options A and E are scaling solutions. Option C is a diagnostic step but disruptive. Option D focuses on data lake, which is downstream from the observed bottleneck.
