220-801 · Question #735
A technician has replaced a riser inside a server and the riser is failing again after reboot. Which of the following should have been used when initially replacing the riser?
The correct answer is D. ESD mat. Electrostatic discharge (ESD) can silently destroy sensitive components like riser cards; an ESD mat provides a grounded surface that continuously dissipates static charge during handling.

Why each option
Electrostatic discharge (ESD) can silently destroy sensitive components like riser cards; an ESD mat provides a grounded surface that continuously dissipates static charge during handling.
Compressed air removes dust and debris from components but provides no protection against electrostatic discharge damage.
Vacuum cleaners can generate and transfer static electricity, actually increasing ESD risk rather than preventing it.
Proper cable management improves airflow and organization inside the server but does not protect components from ESD during installation.
An ESD mat connects to ground and constantly drains static buildup from both the technician and components placed on it, preventing the high-voltage discharge that can permanently damage semiconductors without producing any visible sign of failure.
Concept tested: ESD mat use during component installation
