QuestionQ42

Hardware and Network Troubleshooting

A customer recently lost data due to several unexpected shutdowns. Data integrity is important to the customer. Which of the following features should the technician choose to prevent data loss?

Explanation

An Uninterruptible Power Supply (UPS) provides battery backup during power failures, allowing the system time to complete critical write operations to disk and perform a graceful shutdown. This prevents data corruption that occurs when sudden power loss interrupts file system writes and database operations, protecting data integrity.
