Sample resumes in this discipline contain responsibilities like maintaining servers already installed and set up with custom builds and applications on the network; creating, deleting and modifying local user and group accounts, as well as LDAP user and group accounts; and troubleshooting and fixing NFS, TCP/IP and other protocols problems. While some Linux certificate programs require folks to be able to show a high school diploma or GED on their resumes, most only require the permission of the person who heads the program.
