If a switch port receives a new frame while it is actively transmitting a previous frame, how does it process the frames?
Correct Answer: C
Answer C is the technically correct selection. A switch queues a new frame if the egress port is already transmitting another frame. Ethernet interfaces transmit one frame at a time on the link, so buffering handles temporary contention. This aligns with Cisco CCNA 200-301 v1.1 because the exam blueprint requires engineers to recognize operational behaviour from configuration symptoms and topology requirements. The switch does not drop a valid new frame just because another frame is currently being transmitted unless buffers are exhausted. Treat the distractors carefully: most are real Cisco terms, but they solve a different problem or operate at a different layer. The selected answer is the one that would be used by an engineer on the device or in the design to produce the outcome stated in the question.
