Explanation
The Broker VM for Cortex XDR is a virtual machine that serves as the central communication hub for all Cortex XDR agents deployed in your organization. It enables agents to communicate with the Cortex XDR cloud service and allows you to manage and monitor the agents' activities from a centralized location. The system requirements for the Broker VM are as follows:
* CPU: 4 cores
* RAM: 8 GB
* Disk space: 256 GB
* Network: Internet access and connectivity to all Cortex XDR agents
The disk space requirement is based on the number of agents and the frequency of content updates. The Broker VM stores the content updates locally and distributes them to the agents. The disk spacealso depends on the retention period of the content updates, which can be configured in the Broker VM settings. The default retention period is 30 days.

Explanation
When creating a scheduled report in Cortex XDR, the option to run quarterly on a certain day and time is not available. You can only schedule reports to run daily, weekly, or monthly. You can also specify the start and end dates, the time zone, and the recipients of the report. Scheduled reports are useful for generating regular reports on the security events, incidents, alerts, or endpoints in your network. You can create scheduled reports from the Reports page in the Cortex XDR console, or from the Query Center by saving a query as a report.
