CompTIA Security+ (SY0-701) — Question 404

Which of the following is the main consideration when a legacy system that is a critical part of a company's infrastructure cannot be replaced?

Answer options

• A. Resource provisioning
• B. Cost
• C. Single point of failure
• D. Complexity

Correct answer: C

Explanation

The correct answer is C, as a single point of failure in a legacy system can jeopardize the entire infrastructure if that system is critical and irreplaceable. Options A and B are important considerations but do not address the immediate risk of operational downtime caused by reliance on a single legacy system. Option D, while relevant, does not capture the urgency of potential failure associated with that system.
