I said to myself that I would never do this but I find myself doing now..

I have a phone interview tomorrow for a network support technician position. I'm not going to say that I'm just nervous but I like to know what I'll be going into. Does anyone have any idea the type of questions that might be asked? The job description is below.

• Diagnoses and resolves network-layer issues related to passive and active
network hardware, servers, IP address problems, network connection problems,
and network-centered system configuration issues

One last question; what is the average salary for someone working in a NOC? lol. Not talking specifics but a ball park number...
(already knows someone will say $0-$1,000,000...lol)
