Sure Pass Exam SY0-701 PDF

A legal hold is the correct answer because the organization is preserving potentially relevant evidence after a suspected breach involving sensitive client information. In incident response and governance, legal hold prevents deletion, alteration, or routine retention-policy destruction of data that may be required for litigation, regulatory investigation, discovery, or internal investigation. Logs, server images, and email communications are exactly the kinds of records that may become evidence. Chain of custody is related but narrower: it documents who handled evidence, when, and how integrity was maintained. Root cause analysis happens later to determine why the breach occurred. Containment focuses on stopping spread or limiting damage. Here, the key action is preservation of records.

Systems that control physical industrial processes—such as pumping gas, water control, electrical grids, or manufacturing lines—fall under SCADA (Supervisory Control and Data Acquisition) environments. SCADA systems are part of larger OT (Operational Technology) infrastructures and manage sensors, actuators, valves, flow controls, and telemetry.

CompTIA Security+ SY0-701 explains that SCADA environments typically:

Use legacy protocols (e.g., Modbus, DNP3)

Require high availability

Often run outdated operating systems

Have control systems that cannot easily be patched

Require specialized segmentation and monitoring

This exactly matches the scenario describing a “specialized legacy platform controlling gas flow inside pipes.”

IaaS (A) is cloud infrastructure and unrelated to industrial control. SDN (C) relates to software-defined networking, not physical industrial controls. IoT (D) includes smart devices but is not typically used for large-scale industrial gas control.

Thus, securing SCADA is the correct answer.
