Quizplus · Accepted Answer

The lower sublayer of the MAC layer that uses a contention algorithm to provide access to all traffic is the Distributed Coordination Function (DCF). Option A refers to the Point Coordination Function (PCF), which is an optional addition to the MAC layer that allows for coordinated access to the wireless medium. Option B refers to the Inter-Frame Space (IFS), which is a time interval that exists between frames and allows for the differentiation between various types of frames. Option D refers to the Logical Link Control (LLC) layer, which is the upper sublayer of the MAC layer responsible for the establishment, maintenance, and termination of logical links between network devices.
