Mobile Devices
Introduction
Mobile devices are in abundance in the workplace, ranging from laptops to tablets and smartphones. It’s therefore important that IT technicians have working knowledge of each type of device, including both the storage used and the method of its migration from legacy to modern storage.
Additionally, in your own career, you may have to enable security for smartphones that require you to set up multifactor or biometric authentication, set up cellular communications and mobile hotspots, or connect a corporate user’s Bluetooth headset. And, for laptop queries, whether it requires the order of a new device for the engineering department, installation of a new wireless card, or troubleshooting of the display screen, your understanding of laptop hardware, components, and types and size of cards is crucial to ensuring the support you offer is reliable and effective.
In the CompTIA A+ Core 1 (220-1101) exam, Domain 1.0 Mobile Devices is further broken down into the following core objectives:
1.1 Given a scenario, install and configure laptop hardware and components1.2 Compare and contrast the display components of mobile devices1.3 Given a scenario, set up and configure accessories and ports of mobile devices1.4 Given a scenario, configure basic mobile-device network connectivity and application supportThe rest of this chapter is committed to practice. For each of the concepts defined above, you will be given a series of questions designed to test your knowledge of each core 1 objective as defined by the official certification exam guidance for this domain. Once you have completed these questions and ensured you understand the concepts behind them, you should be fully prepared to do the same in your CompTIA A+ Core 1 (220-1101) exam.

Networking
Introduction
Modern technology is increasingly characterized by the interconnectivity of our devices. This means that to keep pace with this progress and provide consistent and effective support, it is imperative that IT professionals have a working knowledge of networking concepts ranging from IP addresses to the different types of wireless networks.
You will need to know what ports different applications use in order to open those ports on the firewall and allow them to communicate. IT administrators also need to know how to troubleshoot issues when users cannot connect to the network, whether the source of the problem is a DNS or IP error. Wireless networks are a common part of everyday life, and it is vital that you have the knowledge and experience to determine which type of wireless network is best for a given scenario. The practice test in this chapter will test the application of the information that you have gained from previous study.
In the CompTIA A+ Core 1 (220-1101) certification examination, Domain 2.0 Networking makes up 20% of the assessment and is therefore a vital component of a student’s successful preparation. This domain is further broken down into the following core objectives:
2.1 Compare and contrast Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) ports, protocols, and their purposes2.2 Compare and contrast common networking hardware2.3 Compare and contrast protocols for wireless networking2.4 Summarize services provided by networked hosts2.5 Given a scenario, install and configure basic wired/wireless small office/home office (SOHO) networks2.6 Compare and contrast common network configuration concepts2.7 Compare and contrast internet connection types, network types, and their features2.8 Given a scenario, use networking toolsThe rest of this chapter is committed to practice. For each of the concepts defined above, you will be given a series of questions designed to test your knowledge of each core 1 objective as defined by the official certification exam guidance for this domain. Once you have completed these questions and ensured you understand the concepts behind them, you should be fully prepared to do the same on your CompTIA A+ Core 1 (220-1101) exam.
