Is cisco ccna or ccna data center enough for IT career
I really am looking for a new job in IT. Did my share of time on level 1 and tier 2 as call center help desk for Xbox Live and cable, satellite technical support units. Love the gaming industry lots, had a blast. Wouldn't mind a future there. I really have started studying Linux more but became confused and a bit brain stumped with it. Very good with Windows products desktop and server, active directory and really want to be more valued as a IT candidate. Cisco is a interest to me and the CCNA data center or CCNA routing and switching seem like a good start. To have a good career in a data center role or have a chance at network engineering, what are the best skills, books and software to get familiar with or be certified in?
