D) ILS

Question 23

A(n) _________________________ is a grouping of network devices that is not restricted to a physical segment or switch.

A) Pruning
B) Trunking
C) Framing
D) Router-on-a-stick

Question 25

STP uses the ______________________________ to interrupt the logical loop created by a physical loop in a bridged/switched environment.

Question 26

Briefly describe the VTP device modes.
