Hardware

The first domain for the 220-702 exam is hardware, which is a continuation of the hardware domain in the 220-701 exam. Different from the hardware domain in the 220-701 exam, the 220-702 exam focuses on installing, configuring, and troubleshooting the hardware components of the PC. Out of the four domains for the 220-702 exam, the hardware domain is the largest and takes up 38%.

The given objectives for this domain of the 220-702 exam are as follows:

. 1.1—Given a scenario, install, configure, and maintain personal computer components

. 1.2—Given a scenario, detect problems, troubleshoot, and repair/replace personal computer components

. 1.3—Given a scenario, install, configure, detect problems, troubleshoot, and repair/replace laptop components

. 1.4—Given a scenario, select and use the following tools

. 1.5—Given a scenario, detect and resolve common printer issues
