Explanation
When deploying Cortex XDR agent on Kubernetes clusters as a DaemonSet, the license required is Cortex XDR Cloud per Host. This license allows you to protect and monitor your cloud workloads, such as Kubernetes clusters, containers, and serverless functions, using Cortex XDR. With Cortex XDR Cloud per Host license, you can deploy Cortex XDR agents as DaemonSets on your Kubernetes clusters, which ensures that every node in the cluster runs a copy of the agent. The Cortex XDR agent collects and sends data from the Kubernetes cluster, such as pod events, container logs, and network traffic, to the Cortex Data Lake for analysis and correlation. Cortex XDR can then detect and respond to threats across your cloud environment, and provide visibility and context into your cloud workloads. The Cortex XDR Cloud per Host license is based on the number of hosts that run the Cortex XDR agent, regardless of the number of containers or functions on each host. A host is defined as a virtual machine, a physical server, or a Kubernetes node that runs the Cortex XDR agent. You can read more about the Cortex XDR Cloud per Host license and how to deploy Cortex XDR agent on Kubernetes clusters here1 and here2. References:

Explanation
The objects that are considered to be sensors with a Cortex XDR Prevent license are Cortex XDR agents and Palo Alto Networks Next-Generation Firewalls. These are the two sources of data that Cortex XDR can collect and analyze for threat detection and response. Cortex XDR agents are software components that run on endpoints, such as Windows, Linux, and Mac devices, and provide protection against malware, exploits, and fileless attacks. Cortex XDR agents also collect and send endpoint data, such as process activity, network traffic, registry changes, and user actions, to the Cortex Data Lake for analysis and correlation. Palo Alto Networks Next-Generation Firewalls are network security devices that provide visibility and control over network traffic, and enforce security policies based on applications, users, and content. Next-Generation Firewalls also collect and send network data, such as firewall logs, DNS logs, HTTP headers, and WildFire verdicts, to the Cortex Data Lake for analysis and correlation. By integrating data from both Cortex XDR agents and Next-Generation Firewalls, Cortex XDR can provide a comprehensive view of the attack surface and detect threats across the network and endpoint layers.

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. References:
