A.
It is harder to sniff traffic since the computers have virtual private connections.

B.
They are just as unsafe as non-switched environments.

C.
The data link encryption does not permit wiretapping.

D.
Switches are more intelligent than bridges and implement security mechanisms.

Explanation:
Switched environments use switches to allow different network segments
and/or systems to communicate. When this communication takes place, a virtual

connection, broadcast and collision data are not available to other systems, as in
an environment that uses only bridges and routers.

A is the best answer of the options
