1.2 Given a scenario, install components within the display of a laptop.
1.3 Given a scenario, use appropriate laptop features.
1.4 Compare and contrast characteristics of various types of other mobile devices.
1.5 Given a scenario, connect and configure accessories and ports of other mobile devices.
1.6 Given a scenario, configure basic mobile device network connectivity and application support.
1.7 Given a scenario, use methods to perform mobile device synchronization.
The CompTIA A+ (220-1001) exam's second domain focuses on comparing and contrasting common networking hardware and devices, installing and configuring wired and wireless networks, explaining common network configuration protocols, and many more. Networking, domain number two, is alone accountable for 20% of the questions in the CompTIA A+ exam.
Networking, domain number two, is divided into eight major parts:
2.1 Compare and contrast TCP and UDP ports, protocols, and their purposes.
2.2 Compare and contrast common networking hardware devices.
2.3 Given a scenario, install and configure a basic wired/wireless SOHO network.
2.4 Compare and contrast wireless networking protocols.
2.5 Summarize the properties and purposes of services provided by networked hosts.
2.6 Explain common network configuration concepts.
2.7 Compare and contrast Internet connection types, network types, and their features.
2.8 Given a scenario, use appropriate networking tools.
CompTIA A+ exam's third domain covers the basic cable types, features, their purposes, identifying standard connector types, installing and configuring storage devices, SOHO multifunction devices, and much more. The hardware domain accounts for 27% of the CompTIA A+ certification exam questions.
Hardware, domain number three, focuses on the following major sectors:
3.1 Explain basic cable types, features, and their purposes.
3.2 Identify common connector types.
3.3 Given a scenario, install RAM types.
3.4 Given a scenario, select, install and configure storage devices.
3.5 Given a scenario, install and configure motherboards, CPUs, and add-on cards.
3.6 Explain the purposes and uses of various peripheral types.
3.7 Summarize power supply types and features.
3.8 Given a scenario, select and configure appropriate components for a custom PC configuration to meet customer specifications or needs.
3.9 Given a scenario, install and configure common devices.
3.10 Given a scenario, configure SOHO multifunction devices/printers and settings.
3.11 Given a scenario, install and maintain various print technologies.
Virtualization and cloud computing, the fourth domain of the CompTIA A+ certification exam, covers cloud computing concepts, setting and configuring client-side concepts. The domain is responsible for 12% of the questions in the exam.
Virtualization and cloud computing domain shares the following two significant parts in the exam: 4.1 Compare and contrast cloud computing concepts.
-Common cloud models
4.2 Given a scenario, set up and configure client-side virtualization.
The hardware and network troubleshooting, domain number five of the CompTIA A+ certification exam, covers a wide range of topics. This includes troubleshooting problems related to the motherboard, RAM, CPUs, common mobile device issues, printers, and much more. This domain is accountable for 27% of the questions in the CompTIA A+ exam.
The domain is divided into seven critical parts:
5.1 Given a scenario, use the best practice methodology to resolve problems.
5.2 Given a scenario, troubleshoot problems related to motherboards, RAM, CPUs, and power.
5.3 Given a scenario, troubleshoot hard drives and RAID arrays.
5.4 Given a scenario, troubleshoot video, projector, and display issues.
5.5 Given a scenario, troubleshoot common mobile device issues while adhering to the appropriate procedures.
5.6 Given a scenario, troubleshoot printers.
5.7 Given a scenario, troubleshoot common wired and wireless network problems.
