Overview of this book

CompTIA Server+ Certification is one of the top 5 IT certifications that is vendor neutral.System administrators opt for CompTIA server+ Certification to gain advanced knowledge of concepts including troubleshooting and networking. This book will initially start with the configuration of a basic network server and the configuration for each of its myriad roles. The next set of chapters will provide an overview of the responsibilities and tasks performed by a system administrator to manage and maintain a network server. Moving ahead, you will learn the basic security technologies, methods, and procedures that can be applied to a server and its network. Next, you will cover the troubleshooting procedures and methods in general, and specifically for hardware, software, networks, storage devices, and security applications. Toward the end of this book, we will cover a number of troubleshooting and security mitigation concepts for running admin servers with ease. This guide will be augmented by test questions and mock papers that will help you obtain the necessary certification. By the end of this book, you will be in a position to clear Server+ Certification with ease.

Fiber-optic cabling

Networks that require longer distances and higher bandwidth than copper cabling can provide are candidates for fiber-optic cabling. Fiber-optic cables have two advantages over copper twisted-pair cables: range and bandwidth.

The maximum range on fiber-optic lines is around 20 km, whereas the maximum range for copper twisted-pair cables is, by standard, 100 meters or less. Bandwidth is another area in which fiber-optic cable surpasses copper. There are fiber-optic cables with bandwidth ratings of up to 60 Tbps, but fiber-optic network cabling is generally in the 10 Gbps to 100 Gbps range.

The following table summarizes the capability differences between fiber-optic and copper twisted-pair cabling:
