Palo Alto Networks XDR Engineer Sample Questions (Q51-Q56):

NEW QUESTION # 51
What is the earliest time frame an alert could be automatically generated once the conditions of a new correlation rule are met?

A. Immediately
B. Between 10 and 20 minutes
C. Between 30 and 45 minutes
D. 5 minutes or less

Answer: D

Explanation:
In Cortex XDR,correlation rulesare used to detect specific patterns or behaviors by analyzing ingested data and generating alerts when conditions are met. The time frame for alert generation depends on the data ingestion pipeline, the processing latency of the Cortex XDR backend, and the rule's evaluation frequency.
For a new correlation rule, once the conditions are met (i.e., the relevant events are ingested and processed), Cortex XDR typically generates alerts within a short time frame, often5 minutes or less, due to its near-real- time processing capabilities.
* Correct Answer Analysis (C):Theearliest time framefor an alert to be generated is5 minutes or less, as Cortex XDR's architecture is designed to process and correlate events quickly. This accounts for the time to ingest data, evaluate the correlation rule, and generate the alert in the system.
* Why not the other options?
* A. Between 30 and 45 minutes: This time frame is too long for Cortex XDR's near-real-time detection capabilities. Such delays might occur in systems with significant processing backlogs, but not in a properly configured Cortex XDR environment.
* B. Immediately: While Cortex XDR is fast, "immediately" implies zero latency, which is not realistic due to data ingestion, processing, and rule evaluation steps. A small delay (within 5 minutes) is expected.
* D. Between 10 and 20 minutes: This is also too long for the earliest possible alert generation in Cortex XDR, as the system is optimized for rapid detection and alerting.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains correlation rule processing: "Alerts are generated within 5 minutes or less after the conditions of a correlation rule are met, assuming data is ingested and processed in near real-time" (paraphrased from the Correlation Rules section). TheEDU-262: Cortex XDR Investigation and Responsecourse covers detection engineering, stating that "Cortex XDR's correlation engine processes rules and generates alerts typically within a few minutes of event ingestion" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "detection engineering" as a key exam topic, encompassing correlation rule alert generation.

NEW QUESTION # 52
After deploying Cortex XDR agents to a large group of endpoints, some of the endpoints have a partially protected status. In which two places can insights into what is contributing to this status be located? (Choose two.)

A. Asset Inventory
B. Management Audit Logs
C. All Endpoints page
D. XQL query of the endpoints dataset

Answer: C,D

Explanation:
In Cortex XDR, apartially protected statusfor an endpoint indicates that some agent components or protection modules (e.g., malware protection, exploit prevention) are not fully operational, possibly due to compatibility issues, missing prerequisites, or configuration errors. To troubleshoot this status, engineers need to identify the specific components or issues affecting the endpoint, which can be done by examining detailed endpoint data and status information.
* Correct Answer Analysis (B, C):
* B. XQL query of the endpoints dataset: AnXQL (XDR Query Language)query against the endpoints dataset (e.g., dataset = endpoints | filter endpoint_status =
"PARTIALLY_PROTECTED" | fields endpoint_name, protection_status_details) provides detailed insights into the reasons for the partially protected status. The endpoints dataset includes fields like protection_status_details, which specify which modules are not functioning and why.
* C. All Endpoints page: TheAll Endpoints pagein the Cortex XDR console displays a list of all endpoints with their statuses, including those that are partially protected. Clicking into an endpoint's details reveals specific information about the protection status, such as which modules are disabled or encountering issues, helping identify the cause of the status.
* Why not the other options?
* A. Management Audit Logs: Management Audit Logs track administrative actions (e.g., policy changes, agent installations), but they do not provide detailed insights into the endpoint's protection status or the reasons for partial protection.
* D. Asset Inventory: Asset Inventory provides an overview of assets (e.g., hardware, software) but does not specifically detail the protection status of Cortex XDR agents or the reasons for partial protection.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains troubleshooting partially protected endpoints:"Use the All Endpoints page to view detailed protection status, and run an XQL query against the endpoints dataset to identify specific issues contributing to a partially protected status" (paraphrased from the Endpoint Management section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers endpoint troubleshooting, stating that "the All Endpoints page and XQL queries of the endpoints dataset provide insights into partial protection issues" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "maintenance and troubleshooting" as a key exam topic, encompassing endpoint status investigation.

NEW QUESTION # 53
What will enable a custom prevention rule to block specific behavior?

A. A custom behavioral indicator of compromise (BIOC) added to an Exploit profile
B. A custom behavioral indicator of compromise (BIOC) added to a Restriction profile
C. A correlation rule added to an Agent Blocking profile
D. A correlation rule added to a Malware profile

Answer: B

Explanation:
In Cortex XDR,custom prevention rulesare used to block specific behaviors or activities on endpoints by leveragingBehavioral Indicators of Compromise (BIOCs). BIOCs define patterns of behavior (e.g., specific process executions, file modifications, or network activities) that, when detected, can trigger preventive actions, such as blocking a process or isolating an endpoint. These BIOCs are typically associated with a Restriction profile, which enforces blocking actions for matched behaviors.
* Correct Answer Analysis (C):Acustom behavioral indicator of compromise (BIOC)added to a Restriction profileenables a custom prevention rule to block specific behavior. The BIOC defines the behavior to detect (e.g., a process accessing a sensitive file), and the Restriction profile specifies the preventive action (e.g., block the process). This configuration ensures that the identified behavior is blocked on endpoints where the profile is applied.
* Why not the other options?
* A. A correlation rule added to an Agent Blocking profile: Correlation rules are used to generate alerts by correlating events across datasets, not to block behaviors directly. There is no
"Agent Blocking profile" in Cortex XDR; this is a misnomer.
* B. A custom behavioral indicator of compromise (BIOC) added to an Exploit profile:
Exploit profiles are used to detect and prevent exploit-based attacks (e.g., memory corruption), not general behavioral patterns defined by BIOCs. BIOCs are associated with Restriction profiles for blocking behaviors.
* D. A correlation rule added to a Malware profile: Correlation rules do not directly block behaviors; they generate alerts. Malware profiles focus on file-based threats (e.g., executables analyzed by WildFire), not behavioral blocking via BIOCs.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains BIOC and Restriction profiles: "Custom BIOCs can be added to Restriction profiles to block specific behaviors on endpoints, enabling tailored prevention rules" (paraphrased from the BIOC and Restriction Profile sections). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers prevention rules, stating that "BIOCs in Restriction profiles enable blocking of specific endpoint behaviors" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "detection engineering" as a key exam topic, encompassing BIOC and prevention rule configuration.

NEW QUESTION # 54
How long is data kept in the temporary hot storage cache after being queried from cold storage?

A. 1 hour, re-queried to a maximum of 12 hours
B. 24 hours, re-queried to a maximum of 7 days
C. 24 hours, re-queried to a maximum of 14 days
D. 1 hour, re-queried to a maximum of 24 hours

Answer: B

Explanation:
In Cortex XDR, data is stored in different tiers:hot storage(for recent, frequently accessed data),cold storage (for older, less frequently accessed data), and atemporary hot storage cachefor data retrieved from cold storage during queries. When data is queried from cold storage, it is moved to the temporary hot storage cache to enable faster access for subsequent queries. The question asks how long this data remains in the cache and the maximum duration for re-queries.
* Correct Answer Analysis (B):Data retrieved from cold storage is kept in the temporary hot storage cache for24 hours. If the data is re-queried within this period, it remains accessible in the cache. The maximum duration for re-queries is7 days, after which the data may need to be retrieved from cold storage again, incurring additional processing time.
* Why not the other options?
* A. 1 hour, re-queried to a maximum of 12 hours: These durations are too short and do not align with Cortex XDR's data retention policies for the hot storage cache.
* C. 24 hours, re-queried to a maximum of 14 days: While the initial 24-hour cache duration is correct, the 14-day maximum for re-queries is too long and not supported by Cortex XDR's documentation.
* D. 1 hour, re-queried to a maximum of 24 hours: The 1-hour initial cache duration is incorrect, as Cortex XDR retains queried data for 24 hours.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains data storage: "Data queried from cold storage is cached in hot storage for 24 hours, with a maximum re-query period of 7 days" (paraphrased from the Data Management section). TheEDU-262: Cortex XDR Investigation and Responsecourse covers data retention, stating that "queried cold storage data remains in the hot cache for 24 hours, accessible for up to 7 days with re-queries" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "maintenance and troubleshooting" as a key exam topic, encompassing data storage management.

NEW QUESTION # 55
When using Kerberos as the authentication method for Pathfinder, which two settings must be validated on the DNS server? (Choose two.)

A. Reverse DNS zone
B. Reverse DNS records
C. AD DS-integrated zones
D. DNS forwarders

Answer: A,B

Explanation:
Pathfinderin Cortex XDR is a tool for discovering unmanaged endpoints in a network, often using authentication methods likeKerberosto access systems securely. Kerberos authentication relies heavily on DNS for resolving hostnames and ensuring proper communication between clients, servers, and the Kerberos Key Distribution Center (KDC). Specific DNS settings must be validated to ensure Kerberos authentication works correctly for Pathfinder.
* Correct Answer Analysis (B, C):
* B. Reverse DNS zone: Areverse DNS zoneis required to map IP addresses to hostnames (PTR records), which Kerberos uses to verify the identity of servers and clients. Without a properly configured reverse DNS zone, Kerberos authentication may fail due to hostname resolution issues.
* C. Reverse DNS records:Reverse DNS records(PTR records) within the reverse DNS zone must be correctly configured for all relevant hosts. These records ensure that IP addresses resolve to the correct hostnames, which is critical for Kerberos to authenticate Pathfinder's access to endpoints.
* Why not the other options?
* A. DNS forwarders: DNS forwarders are used to route DNS queries to external servers when a local DNS server cannot resolve them. While useful for general DNS resolution, they are not specifically required for Kerberos authentication or Pathfinder.
* D. AD DS-integrated zones: Active Directory Domain Services (AD DS)-integrated zones enhance DNS management in AD environments, but they are not strictly required for Kerberos authentication. Kerberos relies on proper forward and reverse DNS resolution, not AD-specific DNS configurations.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains Pathfinder configuration: "For Kerberos authentication, ensure that the DNS server has a properly configured reverse DNS zone and reverse DNS records to support hostname resolution" (paraphrased from the Pathfinder Configuration section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers Pathfinder setup, stating that "Kerberos requires valid reverse DNS zones and PTR records for authentication" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "planning and installation" as a key exam topic, encompassing Pathfinder authentication settings.
