Other certifications to consider investing in, informed by how the above investments work out:
CompTIA Linux+ Powered by LPI: Linux installation, system architecture, GNU and UNIX commands, and user interfaces and desktops
All of us?
CompTIA Server+: Building, maintaining and troubleshooting server hardware and software
CompTIA Project+: Project management process, including initiation, planning, execution and support
