CompTIA CASP+ (CAS-003) — Question 243

An organization is integrating an ICS and wants to ensure the system is cyber resilient. Unfortunately, many of the specialized components are legacy systems that cannot be patched. The existing enterprise consists of mission-critical systems that require 99.9% uptime. To assist in the appropriate design of the system given the constraints, which of the following MUST be assumed?

Answer options

• A. Vulnerable components
• B. Operational impact due to attack
• C. Time critically of systems
• D. Presence of open-source software

Correct answer: B

Explanation

The correct answer is B, as understanding the operational impact due to an attack is crucial for designing a resilient system. Options A and C do not directly address the design needs for resilience, while D is irrelevant since the presence of open-source software is not a guaranteed factor in the context given.
