NEW QUESTION # 37
In the deployment of which Broker VM applet are you required to install a strong cipher SHA256-based SSL certificate?
Answer: A
Explanation:
The Agent Installer and Content Caching applet of the Broker VM is used to download and cache the Cortex XDR agent installation packages and content updates from Palo Alto Networks servers. This applet also acts as a proxy server for the Cortex XDR agents to communicate with the Cortex Data Lake and the Cortex XDR management console. To ensure secure communication between the Broker VM and the Cortex XDR agents, you are required to install a strong cipher SHA256-based SSL certificate on the Broker VM. The SSL certificate must have a common name or subject alternative name that matches the Broker VM FQDN or IP address. The SSL certificate must also be trusted by the Cortex XDR agents, either by using a certificate signed by a public CA or by manually installing the certificate on the endpoints. Reference:

NEW QUESTION # 38
When reaching out to TAC for additional technical support related to a Security Event; what are two critical pieces of information you need to collect from the Agent? (Choose Two)
Answer: C,D
Explanation:
When reaching out to TAC for additional technical support related to a security event, two critical pieces of information you need to collect from the agent are:
The agent technical support file. This is a file that contains diagnostic information about the agent, such as its configuration, status, logs, and system information. The agent technical support file can help TAC troubleshoot and resolve issues with the agent or the endpoint. You can generate and download the agent technical support file from the Cortex XDR console, or from the agent itself.
The prevention archive from the alert. This is a file that contains forensic data related to the alert, such as the process tree, the network activity, the registry changes, and the files involved. The prevention archive can help TAC analyze and understand the alert and the malicious activity. You can generate and download the prevention archive from the Cortex XDR console, or from the agent itself.
The other options are not critical pieces of information for TAC, and may not be available or relevant for every security event. For example:
The distribution id of the agent is a unique identifier that is assigned to the agent when it is installed on the endpoint. The distribution id can help TAC identify the agent and its profile, but it is not sufficient to provide technical support or forensic analysis. The distribution id can be found in the Cortex XDR console, or in the agent installation folder.
A list of all the current exceptions applied to the agent is a set of rules that define the files, processes, or behaviors that are excluded from the agent's security policies. The exceptions can help TAC understand the agent's configuration and behavior, but they are not essential to provide technical support or forensic analysis. The exceptions can be found in the Cortex XDR console, or in the agent configuration file.
The unique agent id is a unique identifier that is assigned to the agent when it registers with Cortex XDR. The unique agent id can help TAC identify the agent and its endpoint, but it is not sufficient to provide technical support or forensic analysis. The unique agent id can be found in the Cortex XDR console, or in the agent log file.

NEW QUESTION # 39
Phishing belongs to which of the following MITRE ATT&CK tactics?
Answer: A
Explanation:
Phishing is a technique that belongs to two MITRE ATT&CK tactics: Reconnaissance and Initial Access. Reconnaissance is the process of gathering information about a target before launching an attack. Phishing for information is a sub-technique of Reconnaissance that involves sending phishing messages to elicit sensitive information that can be used during targeting. Initial Access is the process of gaining a foothold in a network or system. Phishing is a sub-technique of Initial Access that involves sending phishing messages to execute malicious code on victim systems. Phishing can be used for both Reconnaissance and Initial Access depending on the objective and content of the phishing message. Reference:

NEW QUESTION # 40
To stop a network-based attack, any interference with a portion of the attack pattern is enough to prevent it from succeeding. Which statement is correct regarding the Cortex XDR Analytics module?
Answer: B
Explanation:
The correct statement regarding the Cortex XDR Analytics module is D, it interferes with the pattern as soon as it is observed on the endpoint. The Cortex XDR Analytics module is a feature of Cortex XDR that uses machine learning and behavioral analytics to detect and prevent network-based attacks on endpoints. The Cortex XDR Analytics module analyzes the network traffic and activity on the endpoint, and compares it with the attack patterns defined by Palo Alto Networks threat research team. The Cortex XDR Analytics module interferes with the attack pattern as soon as it is observed on the endpoint, by blocking the malicious network connection, process, or file. This way, the Cortex XDR Analytics module can stop the attack before it causes any damage or compromise.
The other statements are incorrect for the following reasons:
A is incorrect because the Cortex XDR Analytics module does interfere with the attack pattern on the endpoint, by blocking the malicious network connection, process, or file. The Cortex XDR Analytics module does not rely on the firewall or any other network device to stop the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the interference.
B is incorrect because the Cortex XDR Analytics module does not interfere with the attack pattern as soon as it is observed by the firewall. The Cortex XDR Analytics module does not depend on the firewall or any other network device to detect or prevent the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the analysis and interference. The firewall may not be able to observe or block the attack pattern if it is encrypted, obfuscated, or bypassed by the attacker.
C is incorrect because the Cortex XDR Analytics module does need to interfere with the attack pattern to prevent the attack. The Cortex XDR Analytics module does not only detect the attack pattern, but also prevents it from succeeding by blocking the malicious network connection, process, or file. The Cortex XDR Analytics module does not rely on any other response mechanism or human intervention to stop the attack, but rather uses the Cortex XDR agent installed on the endpoint to perform the interference.

NEW QUESTION # 41
Which of the following represents the correct relation of alerts to incidents?
Answer: C
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.
