D) the MAC layer is responsible for establishing connectivity to the local network

Question

Quizplus · Accepted Answer

The PMD (Physical Medium Dependent) sublayer is part of the Physical layer, not the Data Link layer. The PLCP (Physical Layer Convergence Protocol) sublayer in IEEE 802.11 is responsible for formatting data received from the MAC layer so that it can be transmitted by the PHY (Physical) layer. The LLC (Logical Link Control) sublayer is part of the Data Link layer, not the Physical layer. The MAC (Media Access Control) layer in IEEE 802 is responsible for establishing connectivity to the local network. Therefore, option B is the correct answer.
