A stormwater bureau needs low-latency treatment for voice while bulk backup flows share remaining bandwidth fairly on the same uplink. Which congestion-management approach fits?
Select an answer to reveal the explanation.
Short Explanation
Voice wants the express lane; backups can share the regular lanes fairly. LLQ gives voice the priority queue, and CBWFQ divvies leftover bandwidth so bulk jobs do not starve each other. One FIFO for everyone is how softphones start sounding like walkie-talkies.
Full Explanation
Low Latency Queuing prioritizes delay-sensitive voice/video while Class-Based Weighted Fair Queuing assigns bandwidth shares to other classes during congestion. A single FIFO cannot protect voice latency. Policing voice to line rate or disabling class-based queuing fails the dual requirement of priority treatment plus fair bulk sharing.
