Palo Alto Networks XSIAM Engineer Sample Questions (Q63-Q68):

NEW QUESTION # 63
A Security Operations Center (SOC) team using Palo Alto Networks XSIAM is experiencing an overwhelming number of low-priority alerts from a specific legacy application server (IP: 10.0.0.5) that generates legitimate network traffic patterns, but these patterns are being flagged by a newly deployed ML-based detection rule. The team wants to suppress these alerts for 30 days while they tune the ML model without impacting other detections for the same application server if a truly malicious event occurs. Which XSIAM configuration method is most appropriate and least likely to introduce significant security blind spots during this temporary exclusion period?

A. Implement an XSIAM 'Exclusion' in the 'Alert Management' section, specifying the 'Detection Rule ID' and a filter for 'source_ip = '10.0.0.5", with a time-bound validity of 30 days.
B. Disable the entire ML-based detection rule globally for 30 days and re-enable it afterward.
C. Create a new XSIAM playbook with a 'Suppress Alert' action based on the source IP 10.0.0.5 and the specific alert name, scheduled to run for 30 days.
D. Modify the ML-based detection rule's query to explicitly exclude events where = '10.0.0.5" using an 'AND NOT clause for the next 30 days.
E. Create a new 'Suppression Rule' in the 'Alert Management' section based on = '10.0.0.5" and 'alert_severity = 'Low" , set to expire in 30 days.

Answer: A

Explanation:
Option C, implementing an XSIAM 'Exclusion' for a specific Detection Rule ID and a targeted filter with a time-bound validity, is the most appropriate. Exclusions allow for granular suppression of specific alerts generated by a rule based on specific criteria (like source IP) without disabling the entire rule or creating broad suppressions. The time-bound nature ensures it's temporary. Option A (playbook) might be an option for more complex automation but for simple alert suppression, an exclusion is more direct. Option B (modifying the rule query) is disruptive and requires rule editing, which is not ideal for temporary suppression. Option D (disabling the rule) creates a significant security blind spot. Option E (Suppression Rule) is similar to Exclusion but 'Exclusion' is directly tied to the rule and intended for fine-tuning rule output.

NEW QUESTION # 64
A global organization uses XSIAM and has a requirement to automate the revocation of user access (e.g., disabling an account in Azure AD) when XSIAM detects a high-fidelity account compromise incident. Due to regulatory compliance (GDPR, CCPA), the automation must ensure that specific personal identifiable information (PII) of the user is never transmitted or stored in the XSIAM playbook itself during the revocation process, only a non-PII identifier (like an employee ID). The external Azure AD integration requires a UPN (User Principal Name) for revocation. How can this be securely and compliantly achieved within XSIAM?

A. Manually identify the UPN from the employee ID and initiate the revocation outside of XSIAM.
B. Store a mapping of non-PII employee IDs to UPNs within the XSIAM playbook as a lookup table.
C. Directly pass the PII (e.g., email address) from the XSIAM incident to the Azure AD revocation action, assuming Azure AD handles PII securely.
D. Rely on XSIAM's internal data masking capabilities to automatically mask PII before sending it to Azure A
E. Implement an intermediate microservice (e.g., serverless function) external to XSIAM. The XSIAM playbook sends the non-PII employee ID to this microservice. The microservice then queries a secure, Pll-compliant HR database to get the UPN and performs the Azure AD revocation, never exposing the UPN to XSIAM directly.

Answer: E

Explanation:
This is a complex PII compliance and automation challenge. Option C is the most robust and compliant solution. By using an intermediate microservice, the XSIAM playbook only handles the non-PII employee ID. The microservice, running in a secure, compliant environment, is responsible for retrieving the sensitive UPN from a trusted PII-compliant source (like an HR database) and then performing the Azure AD revocation. This ensures that PII (the UPN) is never processed or stored within XSIAM's automation context, satisfying the compliance requirement. Direct passing (A) violates PII rules. Storing mappings in the playbook (B) brings PII into XSIAM. XSIAM's data masking (D) might mask, but doesn't prevent temporary processing/storage within the playbook's execution. Manual revocation (E) negates automation.

NEW QUESTION # 65
An XSIAM engineer is observing that a specific custom log source, which frequently contains corrupted or malformed log entries (e.g., incomplete JSON, truncated strings), is causing downstream XQL queries to fail or return inconsistent results, even though the Data Flow parser is designed to handle common cases. This impacts the reliability of security analytics. Which combination of Data Flow practices would best mitigate the impact of these malformed entries on data quality and query reliability, while ensuring valid data is still processed?

A. Option A
B. Option D
C. Option E
D. Option B
E. Option C

Answer: C,D

Explanation:

NEW QUESTION # 66
A large enterprise is migrating its legacy SIEM data into Palo Alto Networks XSIAM. The original SIEM data schema is highly denormalized, leading to redundant information and inefficient querying for threat hunting. To optimize content and improve query performance, a data normalization strategy is critical. Which of the following data modeling rules, when applied within XSIAM's content optimization framework, would be most effective in achieving Third Normal Form (3NF) for event data, specifically for a 'Login Event' dataset?

A. Consolidate 'user_id', 'username', 'email', and 'department' into a single 'user_profile' field using a JSON object to minimize join operations.
B. Ensure that 'login_type' (e.g., 'SSO', 'Local', 'VPN') is directly dependent only on the 'event_id' and not on any other non-key attributes like 'source_ip'.
C. Create a separate lookup table for 'device_info' containing 'device_id', 'device_name', 'os_version', and 'device_owner', and link it to the main 'Login Event' table via 'device id'.
D. Store all 'login_attempts' for a user within a nested array directly inside the 'user_profile' field to maintain contextual integrity.
E. Apply a rule to automatically normalize 'country_code' and 'city' from 'source_ip' using an external geo-IP database, storing them as separate attributes.

Answer: C

Explanation:
To achieve 3NF, transitive dependencies must be eliminated. Option C directly addresses this by creating a separate table (or in XSIAM's context, a separate dataset or normalized entity) for device information. This ensures that 'device_name', 'os_version', and 'device_owner' are dependent on 'device_id' (a primary key in the 'device_info' entity) and not transitively dependent on the primary key of the 'Login Event' table via a non-key attribute. Option B describes 2NF, not strictly 3NF. Option A and D describe denormalization or semi-structured approaches that might be useful for performance in some NoSQL contexts but contradict the goal of 3NF for relational-like efficiency. Option E is about data enrichment, not normalization of existing schema attributes to higher forms.

NEW QUESTION # 67
An organization is migrating from a traditional SIEM to Cortex XSIAM. They have existing log forwarders that send logs to a central syslog aggregator. To minimize changes to the existing infrastructure, the security team decides to point these existing log forwarders to the newly deployed Broker VM instead of the old aggregator. What is the most important configuration aspect on the Broker VM itself to accommodate this strategy?

A. Adjusting the Broker VM's hostname to match the previous syslog aggregator's hostname for seamless redirection.
B. Configuring an outbound proxy server on the Broker VM for internet connectivity.
C. Ensuring the Broker VM's network interface is configured with multiple IP addresses to handle diverse log sources.
D. Enabling the 'Universal Data Collector' service and configuring the appropriate syslog profiles.
E. Increasing the allocated disk space significantly to buffer all incoming logs.

Answer: D

Explanation:
The Broker VM's Universal Data Collector service is specifically designed to receive logs from various sources like syslog. Configuring the appropriate syslog profiles within this service tells the Broker VM how to listen for and parse incoming syslog messages. While disk space (B) is important, it's a sizing consideration, not a configuration aspect for receiving logs. Proxy configuration (C) is for outbound XSIAM communication, not inbound log ingestion. Multiple IP addresses (D) are generally not required for receiving diverse syslog sources, as different ports or source IPs can differentiate them. Changing the hostname (E) is irrelevant for log forwarding, as it relies on IP addresses or DNS names.
