Layer 2 of the OSI model has two sublayers. What are those sublayers, and what are two IEEE standards that
describe technologies at that layer?

A.
LLC and MAC; IEEE 802.2 and 802.3

B.
LLC and MAC; IEEE 802.1 and 802.3

C.
Network and MAC; IEEE 802.1 and 802.3

D.
LLC and MAC; IEEE 802.2 and 802.3

Explanation:
OSI layer is the data link layer. The data link layer is divided into two functional sublayers: the Logical Link
Control (LLC) and the Media Access Control (MAC).
The IEE LLC specification for Ethernet is defined in the IEEE 802.2 standard, while the IEEE MAC specification
for Ethernet is 802.3
Incorrect Answers:
A: LCL is not a sublayer of OSI layer 2.
B: LCL is not a sublayer of OSI layer 2.
C: Network is not a sublayer of OSI layer 2.References:
