CompTIA Cloud+ (CV0-002) — Question 50

A company is looking for a hardware feature with the least amount of downtime in terms of firmware upgrades. Which of the following features BEST meet this requirement?

Answer options

• A. In-service upgrades
• B. Rolling upgrades
• C. Failover upgrades
• D. User-mode upgrades

Correct answer: B

Explanation

The correct answer is B, as rolling upgrades allow for the system to be updated without significant downtime by upgrading components sequentially. In-service upgrades (A) may still cause some downtime, while failover upgrades (C) require a backup system to take over, and user-mode upgrades (D) typically do not address system-wide updates efficiently.
