CompTIA Security+ (SY0-501) — Question 367

Which of the following strategies helps reduce risk if a rollback is needed when upgrading a critical system platform?

Answer options

• A. Non-persistent configuration
• B. Continuous monitoring
• C. Firmware updates
• D. Fault tolerance

Correct answer: A

Explanation

Non-persistent configuration allows for changes to be temporary, making it easier to revert back to the previous state if an upgrade encounters issues. Continuous monitoring, firmware updates, and fault tolerance are important for system reliability and performance, but they do not specifically address the need for an easy rollback during an upgrade.
