You need to be able to passively monitor activity in your perimeter network. Alerted at a potential hazard-use what,

Answer 5

A network intrusion detection system (NIDS)

Question 6

A contrator needs a document that shows the location of the network cabling in the building

Answer 6

Wiring diagram

Question 7
