Dell EMC Specialist – Systems Administrator, SC Series — Question 9

Which component is hot-swappable?

Answer options

• A. SFP
• B. Fan
• C. BBU
• D. Expansion IO module

Correct answer: D

Explanation

The correct answer is D, as the Expansion IO module is designed for hot-swapping, allowing it to be replaced without shutting down the system. Options A, B, and C are typically not hot-swappable; for instance, fans may need to be replaced during maintenance, and SFPs and BBUs are not designed for live replacement.
