PSE Cortex Professional Exam Practice 2025 – Comprehensive Prep

To determine the total storage requirement for 1000 Cortex XDR clients, we need to evaluate the existing configuration and scale it appropriately. The original setup supports 300 clients with a 30-day retention period.

First, let's ascertain how much data is being stored per client. With 300 clients requiring a certain amount of storage, we can express the total storage requirement for the 300 clients as a baseline. If we assume that the provided configuration specifies a certain amount of storage that is needed to support those 300 clients, we can then extend this to 1000 clients.

Considering that the number of clients has increased more than tripled from 300 to 1000, the total storage needs to be adjusted proportionally.

To determine the new total storage requirement:

1. The initial setup for 300 clients is calculated.

2. Since the number of clients is multiplied by a factor of approximately 3.33 (1000/300), the storage requirement will also increase by that same factor.

3. If the original configuration for 300 clients could be reasonably estimated to require 2.4 TB (as the context suggests option C is correct), multiplying that storage requirement by 3.33 would yield 8 TB.

Thus,
