What queue type is used to equally separate traffic into sub-streams?

• A. PCQ
• B. PFIFO
• C. PRIQ
• D. RED

Answer: (A)

Equally distributing traffic into multiple paths is achieved by Per Connection Queuing. This approach creates several sub-queues and assigns each active connection to its own sub-queue, then allocates bandwidth fairly across those sub-queues. That means many simultaneous connections share the link, each getting a fair portion, rather than one connection dominating. In RouterOS, PCQ is designed specifically for this kind of fair division by sub-streams, which is why it’s the right choice here.

PFIFO is a simple first-in, first-out queue that processes packets in arrival order and doesn’t split traffic into multiple streams. PRIQ uses fixed priority levels to decide which traffic to send first but doesn’t ensure equal shares among all active connections. RED is an active queue management technique that helps prevent congestion by probabilistically dropping packets, not by dividing traffic into sub-streams.
