Layer 2 through Layer 7
B.
Layer 3 through Layer 7
C.
Layer 2 through Layer 6
D.
Layer 3 through Layer 6

Explanation:
Deep packet inspection (DPI) is a form of computer network packet filtering that examines the data
part of a through-passing packet, searching for non- protocol compliance or predefined criteria to
decide if the packet can pass.
DPI devices have the ability to look at Layer 2 through Layer 7 of the OSI model.
