Are the study materials I`m using not good enough
Are there any particular topics you had trouble with?
By "globally on by defualt" they mean on every interface. This is true for CDP. And yes, i beleive the max telnet sessions is 5... Can anyone verify? I'm just assuming based on the command to configure the virtual lines "line vty 0 4"
Indeed, not good enough, not good at all actually as Ricka explained, and unfortunately you found out the hard way. I suggest you throw away that PDF (seriously, select and press Shift-delete) and get yourself some decent practice tests... ie. Preplogic, examforce (100 questions free at http://www.examforce.com/customer/special4.php?sid=525 ), transcender, or boson. Even if you would download the demo of all 'ethical' preptest providers you'd be better of than using a **** sheet.
