問題文
A sensor has to be attached so that it watches a copy of the traffic on one switch. What separates using the switch port that is able to see all of the switch traffic from fitting a direct connection to the media itself?
選択肢
- The switch port has to be paid for once per watcher that attaches to it but sees all traffic whatever the load, whereas the direct connection costs nothing and fitting it takes the segment down
- The switch port costs nothing to add and sees all traffic whatever the load, whereas the direct connection has to be bought and can be fitted while the segment carries traffic
- The switch port costs nothing to add yet may miss traffic while the switch is heavily loaded, whereas the direct connection has to be bought and fitting it takes the segment down for a spell
- The switch port can be shared by as many watchers as a site needs and misses nothing under load, whereas the direct connection has to be bought and hides one direction of the traffic
