Correct Answer: D

Explanation: Live terminal session is a feature of Cortex XDR that allows you to remotely access and control endpoints from the Cortex XDR console. With live terminal session, you can execute various actions on the endpoints, such as: Manage Processes: You can view, start, or kill processes on the endpoint, and monitor their CPU and memory usage. Manage Files: You can view, create, delete, or move files and folders on the endpoint, and upload or download files to or from the endpoint. Run Operating System Commands: You can run commands on the endpoint using the native command-line interface of the operating system, such as cmd.exe for Windows, bash for Linux, or zsh for macOS. Run Python Commands and Scripts: You can run Python commands and scripts on the endpoint using the Python interpreter embedded in the Cortex XDR agent. You can use the Python commands and scripts to perform advanced tasks or automation on the endpoint.

Correct 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.

Correct Answer: B

Explanation: The outcome of creating and implementing an alert exclusion is that the Cortex XDR console will hide those alerts that match the exclusion criteria. An alert exclusion is a policy that allows you to filter out alerts that are not relevant, false positives, or low priority, and focus on the alerts that require your attention. When you create an alert exclusion, you can specify the criteria that define which alerts you want to exclude, such as alert name, severity, source, or endpoint. After you create an alert exclusion, Cortex XDR will hide any future alerts that match the criteria, and exclude them from incidents and search query results. However, the alert exclusion does not affect the behavior of the Cortex XDR agent or the security policy on the endpoint. The Cortex XDR agent will still create an alert for the event and apply the appropriate action, such as blocking or quarantining, according to the security policy. The alert exclusion only affects the visibility of the alert on the Cortex XDR console, not the actual protection of the endpoint. Therefore, the correct answer is B, the Cortex XDR console will hide those alerts12 References: Alert Exclusions Create an Alert Exclusion Policy

Correct Answer: C

Explanation: The "assigned to" field value of a new incident that was just reported to Cortex is "Unassigned". This means that the incident has not been assigned to any analyst or group yet, and it is waiting for someone to take ownership of it. The "assigned to" field is one of the default fields that are displayed in the incident layout, and it can be used to filter and sort incidents in the incident list. The "assigned to" field can be changed manually by an analyst, or automatically by a playbook or a rule12. Let's briefly discuss the other options to provide a comprehensive explanation:

A. Pending: This is not the correct answer. Pending is not a valid value for the "assigned to" field. Pending is a possible value for the "status" field, which indicates the current state of the incident. The status field can have values such as

"New", "Active", "Done", "Closed", or "Pending"3.

B. It is blank: This is not the correct answer. The "assigned to" field is never blank for any incident. It always has a default value of "Unassigned" for new incidents, unless a playbook or a rule assigns it to a specific analyst or group12. D. New:

This is not the correct answer. New is not a valid value for the "assigned to" field. New is a possible value for the "status" field, which indicates the current state of the incident. The status field can have values such as "New", "Active", "Done",

"Closed", or "Pending"3.

In conclusion, the "assigned to" field value of a new incident that was just reported to Cortex is "Unassigned". This field can be used to manage the ownership and responsibility of incidents, and it can be changed manually or automatically.

Correct Answer: B

Explanation: If you have an isolated network that is prevented from connecting to the Cortex Data Lake, you can use the Local Agent Proxy setup to facilitate the communication. The Local Agent Proxy is a type of Broker VM that acts as a proxy server for the Cortex XDR agents that are deployed on the isolated network. The Local Agent Proxy enables the Cortex XDR agents to communicate securely with the Cortex Data Lake and the Cortex XDR management console over the internet, without requiring direct access to the internet from the isolated network. The Local Agent Proxy also allows the Cortex XDR agents to download installation packages and content updates from the Cortex XDR management console. To use the Local Agent Proxy setup, you need to deploy a Broker VM on the isolated network and configure it as a Local Agent Proxy. You also need to deploy another Broker VM on a network that has internet access and configure it as a Remote Agent Proxy. The Remote Agent Proxy acts as a relay between the Local Agent Proxy and the Cortex Data Lake. You also need to install a strong cipher SHA256-based SSL certificate on both the Local Agent Proxy and the Remote Agent Proxy to ensure secure communication. You can read more about the Local Agent Proxy setup and how to configure it here1 and here2. References: Local Agent Proxy Configure the Local Agent Proxy Setup
