220-1102 ESD (Electrostatic Discharge) Practice Question
A technician is supporting a service-desk jump box. The immediate goal is to protect components during internal repair. Which tool, control, or procedure is the best fit?
⚠ Common exam trap
A common mix-up: candidates confuse software-based troubleshooting tools (like Event Viewer or System Restore) with hardware safety procedures, failing to recognize that 'protect components during internal repair' explicitly requires physical ESD protection, not software utilities.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ESD strap and mat
C is correct because an ESD strap and mat are specifically designed to protect sensitive electronic components from electrostatic discharge during internal repair. This is a fundamental safety procedure when working inside a computer chassis, as ESD can damage or destroy components without visible signs. The question's context of 'protect components during internal repair' directly aligns with ESD prevention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Local Users and Groups
Why it's wrong here
Local Users and Groups manages account credentials and permissions; it offers no physical protection to components while a technician works inside the case. It is tempting because it secures logical access to the jump box, which is the correct control when restricting who may log on, not when handling hardware.
- ✗
System Restore
Why it's wrong here
System Restore rolls back registry and system file changes; it does not shield hardware from electrostatic discharge or physical damage during internal repair. It is tempting because it protects the operating system's configuration, which is the correct goal when recovering a machine after a faulty driver or update, not when opening the chassis.
- ✓
ESD strap and mat
Why this is correct
An ESD strap and mat provide a controlled path to ground, preventing static discharge from damaging sensitive internal components such as RAM, CPUs and expansion cards during repair. This directly satisfies the stated goal of protecting components while the jump box is opened and handled.
- ✗
Event Viewer
Why it's wrong here
Event Viewer records and displays system, application and security log entries; it cannot prevent electrostatic or physical damage to components during repair. It is tempting because it supports fault diagnosis after an incident, which is the correct tool when investigating why a machine failed, not when protecting parts mid-repair.
