Paloalto Networks XDR-Analyst Dumps Questions Answers

The WSS (WebSocket Secure) protocol is an extension of the WebSocket protocol that provides a secure communication channel over the internet. It is used to establish a persistent, full-duplex communication channel between a client (in this case, the Cortex XDR agent) and a server (such as the Cortex XDR management console or other components). The Cortex XDR agent uses the WSS protocol to establish a secure and real-time bidirectional communication channel with the Cortex XDR management console or other components in the Palo Alto Networks security ecosystem. This communication channel allows the agent to send data, such as security events, alerts, and other relevant information, to the management console, and receive commands, policy updates, and responses in return. By using the WSS protocol, the Cortex XDR agent can maintain a persistent connection with the management console, which enables timely communication of security-related information and allows for efficient incident response and remediation actions. It’s important to note that the other options mentioned in the question also involve communication between the Cortex XDR agent and various components, but they do not specifically mention the use of the WSS protocol. For example:

A. The Cortex XDR agent downloading new security content typically utilizes protocols like HTTP or HTTPS.

B. When the Cortex XDR agent uploads alert data, it may use protocols like HTTP or HTTPS to transmit the data securely.

C. When the Cortex XDR agent connects to WildFire to upload files for analysis, it typically uses protocols like HTTP or HTTPS. Therefore, the correct answer is D, when the Cortex XDR agent establishes a bidirectional communication channel. References:

To pivot within a row to Causality view and Timeline views for further investigation, you can use the Open Card and Open Timeline actions respectively. The Open Card action will open a new tab with the Causality view of the selected row, showing the causal chain of events that led to the alert. The Open Timeline action will open a new tab with the Timeline view of the selected row, showing the chronological sequence of events that occurred on the affected endpoint. These actions allow you to drill down into the details of each alert and understand the root cause and impact of the incident. References:

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
