For a wireless voice client, which QoS mechanism is most important to ensure call quality?

Low latency and jitter through priority queuing

High throughput for bulk data transfer

Packet loss recovery mechanisms

A retail company uses Wi-Fi for point-of-sale (POS) terminals and customer devices. The POS application uses a proprietary TCP port 8443 and must be prioritized over general web browsing. The WLC is AireOS-based. What is the most efficient way to prioritize POS traffic?

Configure a per-client bandwidth contract for the POS terminals and set the WLAN to 'gold' QoS.

Enable WMM and set the WLAN to 'platinum' QoS for all clients.

Use a WLAN ACL to permit TCP 8443 and deny all other traffic from POS terminals.

Create an application-based QoS policy that matches TCP 8443 and assigns it to the voice queue.

Part of the QoS on a Wireless Network domain, which accounts for 10% of the 300-430 exam. Cisco does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 24 practice questions to prepare you well beyond it.
