"  While I think that I have learnt a great deal of acronyms in this course, I feel that it has in NO WAY prepared me to be able to troubleshoot network issues.  There is absolutely no practical knowledge &amp; no virtual hands-on troubleshooting.  There is no \"steps\" on how to do anything.  For example:  a section on Host Files.  I spent 10 minutes trying to find host files on my home computer.  nothing!  All these tools were are told about, but the information on how to use them is sorely lacking.  I was hoping after the vague knowledge that was given to us in the first course, that the second would be more in depth.  Not.  This has been a big disappointment thus far.  "
