Palo Alto Networks XDR Analyst Sample Questions (Q70-Q75):NEW QUESTION # 70
Cortex XDR is deployed in the enterprise and you notice a cobalt strike attack via an ongoing supply chain compromise was prevented on 1 server. What steps can you take to ensure the same protection is extended to all your servers?
  • A. Conduct a thorough Endpoint Malware scan.
  • B. Create lOCs of the malicious files you have found to prevent their execution.
  • C. Enable Behavioral Threat Protection (BTP) with cytool to prevent the attack from spreading.
  • D. Enable DLL Protection on all servers but there might be some false positives.
Answer: B
Explanation:
The best step to ensure the same protection is extended to all your servers is to create indicators of compromise (IOCs) of the malicious files you have found to prevent their execution. IOCs are pieces of information that indicate a potential threat or compromise on an endpoint, such as file hashes, IP addresses, domain names, or registry keys. You can create IOCs in Cortex XDR to block or alert on any file or network activity that matches the IOCs. By creating IOCs of the malicious files involved in the cobalt strike attack, you can prevent them from running or spreading on any of your servers.
The other options are not the best steps for the following reasons:
A is not the best step because conducting a thorough Endpoint Malware scan may not detect or prevent the cobalt strike attack if the malicious files are obfuscated, encrypted, or hidden. Endpoint Malware scan is a feature of Cortex XDR that allows you to scan endpoints for known malware and quarantine any malicious files found. However, Endpoint Malware scan may not be effective against unknown or advanced threats that use evasion techniques to avoid detection.
B is not the best step because enabling DLL Protection on all servers may cause some false positives and disrupt legitimate applications. DLL Protection is a feature of Cortex XDR that allows you to block or alert on any DLL loading activity that matches certain criteria, such as unsigned DLLs, DLLs loaded from network locations, or DLLs loaded by specific processes. However, DLL Protection may also block or alert on benign DLL loading activity that is part of normal system or application operations, resulting in false positives and performance issues.
C is not the best step because enabling Behavioral Threat Protection (BTP) with cytool may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection. Behavioral Threat Protection is a feature of Cortex XDR that allows you to block or alert on any endpoint behavior that matches certain patterns, such as ransomware, credential theft, or lateral movement. Cytool is a command-line tool that allows you to configure and manage the Cortex XDR agent on the endpoint. However, Behavioral Threat Protection may not prevent the attack from spreading if the malicious files are already on the endpoints or if the attack uses other methods to evade detection, such as encryption, obfuscation, or proxy servers.

NEW QUESTION # 71
Which statement is true based on the following Agent Auto Upgrade widget?

  • A. Agent Auto Upgrade was enabled but not on all endpoints.
  • B. There are a total of 689 Up To Date agents.
  • C. There are more agents in Pending status than In Progress status.
  • D. Agent Auto Upgrade has not been enabled.
Answer: A
Explanation:
The Agent Auto Upgrade widget shows the status of the agent auto upgrade feature on the endpoints. The widget displays the number of agents that are up to date, in progress, pending, failed, and not configured. In this case, the widget shows that there are 450 agents that are up to date, 78 in progress, 15 pending, 18 failed, and 128 not configured. This means that the agent auto upgrade feature was enabled but not on all endpoints. Reference:

NEW QUESTION # 72
What should you do to automatically convert leads into alerts after investigating a lead?
  • A. Create IOC rules based on the set of the collected attribute-value pairs over the affected entities concluded during the lead hunting.
  • B. Create BIOC rules based on the set of the collected attribute-value pairs over the affected entities concluded during the lead hunting.
  • C. Lead threats can't be prevented in the future because they already exist in the environment.
  • D. Build a search query using Query Builder or XQL using a list of lOCs.
Answer: A
Explanation:
To automatically convert leads into alerts after investigating a lead, you should create IOC rules based on the set of the collected attribute-value pairs over the affected entities concluded during the lead hunting. IOC rules are used to detect known threats based on indicators of compromise (IOCs) such as file hashes, IP addresses, domain names, etc. By creating IOC rules from the leads, you can prevent future occurrences of the same threats and generate alerts for them.

NEW QUESTION # 73
Which of the following represents the correct relation of alerts to incidents?
  • A. Alerts with same causality chains that occur within a given time frame are grouped together into an Incident.
  • B. Every alert creates a new Incident.
  • C. Alerts that occur within a three-hour time frame are grouped together into one Incident.
  • D. Only alerts with the same host are grouped together into one Incident in a given time frame.
Answer: A
Explanation:
The correct relation of alerts to incidents is that alerts with same causality chains that occur within a given time frame are grouped together into an incident. A causality chain is a sequence of events that are related to the same malicious activity, such as a malware infection, a lateral movement, or a data exfiltration. Cortex XDR uses a set of rules that take into account different attributes of the alerts, such as the alert source, type, and time period, to determine if they belong to the same causality chain. By grouping related alerts into incidents, Cortex XDR reduces the number of individual events to review and provides a complete picture of the attack with rich investigative details1.
Option A is incorrect, because alerts with the same host are not necessarily grouped together into one incident in a given time frame. Alerts with the same host may belong to different causality chains, or may be unrelated to any malicious activity. For example, if a host has a malware infection and a network anomaly, these alerts may not be grouped into the same incident, unless they are part of the same attack.
Option B is incorrect, because alerts that occur within a three hour time frame are not always grouped together into one incident. The time frame is not the only criterion for grouping alerts into incidents. Alerts that occur within a three hour time frame may belong to different causality chains, or may be unrelated to any malicious activity. For example, if a host has a file download and a registry modification within a three hour time frame, these alerts may not be grouped into the same incident, unless they are part of the same attack.
Option D is incorrect, because every alert does not create a new incident. Creating a new incident for every alert would result in alert fatigue and inefficient investigations. Cortex XDR aims to reduce the number of incidents by grouping related alerts into one incident, based on their causality chains and other attributes.

NEW QUESTION # 74
Where would you go to add an exception to exclude a specific file hash from examination by the Malware profile for a Windows endpoint?
  • A. In the Action Center, choose Allow list, select new action, select add to allow list, add your hash to the list, and apply it.
  • B. Find the Malware profile attached to the endpoint, Under Portable Executable and DLL Examination add the hash to the allow list.
  • C. From the rules menu select new exception, fill out the criteria, choose the scope to apply it to, hit save.
  • D. Find the exceptions profile attached to the endpoint, under process exceptions select local analysis, paste the hash and save.
Answer: A
Explanation:
To add an exception to exclude a specific file hash from examination by the Malware profile for a Windows endpoint, you need to use the Action Center in Cortex XDR. The Action Center allows you to create and manage actions that apply to endpoints, such as adding files or processes to the allow list or block list, isolating or unisolating endpoints, or initiating live terminal sessions. To add a file hash to the allow list, you need to choose Allow list, select new action, select add to allow list, add your hash to the list, and apply it. This will prevent the Malware profile from scanning or blocking the file on the endpoints that match the scope of the action. Reference: Cortex XDR 3: Responding to Attacks1, Action Center2
