Certified Network Defender (CND) — Question 8

Which of the following interfaces uses hot plugging technique to replace computer components without the need to shut down the system?

Answer options

• A. SATA
• B. SCSI
• C. IDE
• D. SDRAM

Correct answer: A

Explanation

SATA supports hot swapping, allowing drives to be added or removed while the system is running. SCSI can also support hot plugging, but it's not as commonly associated with consumer devices as SATA. IDE does not support hot plugging capabilities, and SDRAM is a type of memory that cannot be replaced while the system is powered on.
