NEW QUESTION # 69
A correlation rule is created to detect potential insider threats by correlating user login events from one dataset with file access events from another dataset. The rule must retain all user login events, even if there are no matching file access events, to ensure no login activity is missed.
text
Copy
dataset = x
| join (dataset = y)
Which type of join is required to maintain all records from dataset x, even if there are no matching events from dataset y?
Answer: B
Explanation:
A left join keeps all records from the left dataset, even when there is no match in the right dataset, which matches the requirement to retain all user login events from dataset x.
In this case, an inner join would drop unmatched login events, while a right or outer join would preserve a different set of rows than requested.
NEW QUESTION # 70
When onboarding a Palo Alto Networks NGFW to Cortex XDR, what must be done to confirm that logs are being ingested successfully after a device is selected and verified?
Answer: B
Explanation:
When onboarding aPalo Alto Networks Next-Generation Firewall (NGFW)to Cortex XDR, the process involves selecting and verifying the device to ensure it can send logs to Cortex XDR. After this step, confirming successful log ingestion is critical to validate the integration. The most direct and reliable method to confirm ingestion is to query the ingested logs usingXQL (XDR Query Language), which allows the engineer to search for NGFW log data in Cortex XDR.
* Correct Answer Analysis (A):Conduct an XQL query for NGFW log datais the correct action.
After onboarding, the engineer can run an XQL query such as dataset = panw_ngfw_logs | limit 10 to check if NGFW logs are present in Cortex XDR. This confirms that logs are being successfully ingested and stored in the appropriate dataset, ensuring the integration is working as expected.
* Why not the other options?
* B. Wait for an incident that involves the NGFW to populate: Waiting for an incident is not a reliable or proactive method to confirm log ingestion. Incidents depend on detection rules and may not occur immediately, even if logs are beingingested.
* C. Confirm that the selected device has a valid certificate: While a valid certificate is necessary during the onboarding process (e.g., for secure communication), this step is part of the verification process, not a method to confirm log ingestion after verification.
* D. Retrieve device certificate from NGFW dashboard: Retrieving the device certificate from the NGFW dashboard is unrelated to confirming log ingestion in Cortex XDR. Certificates are managed during setup, not for post-onboarding validation.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains NGFW log ingestion validation: "To confirm successful ingestion of Palo Alto Networks NGFW logs, run an XQL query (e.g., dataset = panw_ngfw_logs) to verify that log data is present in Cortex XDR" (paraphrased from the Data Ingestion section). TheEDU-260: Cortex XDR Prevention and Deploymentcourse covers NGFW integration, stating that "XQL queries are used to validate that NGFW logs are being ingested after onboarding" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "data ingestion and integration" as a key exam topic, encompassing log ingestion validation.

NEW QUESTION # 71
An attacker attempts to dump credentials by accessing LSASS memory on a Windows endpoint.
Which Cortex XDR detection capability is most likely involved?
Answer: D
Explanation:
Credential dumping techniques often involve abnormal access to sensitive processes such as LSASS. Behavioral monitoring detects suspicious process interactions, privilege escalation attempts, and memory access patterns commonly associated with credential theft.
NEW QUESTION # 72
A threat hunter suspects lateral movement activity involving compromised credentials. Which telemetry combination provides the strongest evidence during investigation?
Answer: D
Explanation:
Combining authentication telemetry with process execution data helps determine whether suspicious activity originated from stolen credentials, malicious processes, or both. This provides critical context for root-cause analysis.
NEW QUESTION # 73
Which action is being taken with the query below?
dataset = xdr_data
| fields agent_hostname, _time, _product
| comp latest as latest_time by agent_hostname, _product
| join type=inner (dataset = endpoints
| fields endpoint_name, endpoint_status, endpoint_type) as lookup lookup.endpoint_name = agent_hostname
| filter endpoint_status = ENUM.CONNECTED
| fields agent_hostname, endpoint_status, latest_time, _product
Answer: A
Explanation:
The providedXQL (XDR Query Language)query in Cortex XDR retrieves and processes data to provide insights into endpoint activity. Let's break down the query to understand its purpose:
* dataset = xdr_data | fields agent_hostname, _time, _product: Selects thexdr_datadataset (general event data) and retrieves fields for the agent hostname, timestamp, and product (e.g., agent type or component).
* comp latest as latest_time by agent_hostname, _product: Computes the latest timestamp (_time) for each combination of agent_hostname and _product, naming the result latest_time. This identifies the most recent activity for each endpoint and product.
* join type=inner (dataset = endpoints | fields endpoint_name, endpoint_status, endpoint_type) as lookup lookup.endpoint_name = agent_hostname: Performs an inner join with theendpointsdataset, matching endpoint_name (from the endpoints dataset) with agent_hostname (from xdr_data), and retrieves fields like endpoint_status and endpoint_type.
* filter endpoint_status = ENUM.CONNECTED: Filters the results to include only endpoints with a status ofCONNECTED.
* fields agent_hostname, endpoint_status, latest_time, _product: Outputs the final fields: hostname, status, latest activity time, and product.
* Correct Answer Analysis (A):The query ismonitoring the latest activity of endpoints. It calculates the most recent activity (latest_time) for each connected endpoint (agent_hostname) by joining event data (xdr_data) with endpoint metadata (endpoints) and filtering for connected endpoints. This provides a view of the latest activity for active endpoints, useful for monitoring their status and recent events.
* Why not the other options?
* B. Identifying endpoints that have disconnected from the network: The queryfilters for endpoint_status = ENUM.CONNECTED, so it only includes connected endpoints, not disconnected ones.
* C. Monitoring the latest activity of connected firewall endpoints: The query does not filter for firewall endpoints (e.g., using endpoint_type or _product to specify firewalls). It applies to all connected endpoints, not just firewalls.
* D. Checking for endpoints with outdated agent versions: The query does not retrieve or compare agent version information (e.g., agent_version field); it focuses on the latest activity time.
Exact Extract or Reference:
TheCortex XDR Documentation Portalexplains XQL queries: "Queries using comp latest and joins with the endpoints dataset can monitor the latest activity of connected endpoints by calculating the most recent event timestamps" (paraphrased from the XQL Reference Guide). TheEDU-262: Cortex XDR Investigation and Responsecourse covers XQL for monitoring, stating that "combining xdr_data and endpoints datasets with a latest computation monitors recent endpoint activity" (paraphrased from course materials). ThePalo Alto Networks Certified XDR Engineer datasheetincludes "dashboards and reporting" as a key exam topic, encompassing XQL queries for monitoring.
