Which queuing mechanism has no provision for prioritizing or buffering but simply forwards packets in the order they arrive?
- FIFO
- LLQ
- CBWFQ
- WFQ
Explanation: FIFO (First-In, First-Out), also known as first-come, first-served, is the simplest queuing mechanism that buffers and forwards packets in the exact order they arrive. It has no concept of priority or traffic classes, meaning it makes no decisions to reorder packets based on importance; instead, it treats all packets equally within a single queue.
