A campus has a 100 Mbps WAN link. The traffic mix is 40% VoIP, 30% ERP, and 30% internet browsing. The network team wants to ensure VoIP quality and ERP responsiveness, but they also want to avoid over-provisioning the link. They are considering implementing QoS. Which approach is most effective?

Implement QoS with priority queuing for VoIP, bandwidth allocation for ERP, and best-effort for internet browsing.

Upgrade the link to 200 Mbps and implement QoS with priority for VoIP only.

Implement QoS with bandwidth allocation for all traffic classes, without priority queuing.

Implement QoS with strict priority for all traffic classes.

A branch office has a 10 Mbps WAN link. The traffic mix is 50% VoIP, 30% interactive applications, and 20% bulk file transfers. The network team wants to ensure VoIP quality and keep the interactive applications responsive. They are considering implementing QoS. Which QoS strategy is most appropriate?

Use strict priority queuing for all traffic classes.

Use only bandwidth allocation for all traffic classes.

Use compression on the link and rely on FIFO queuing.

Use priority queuing for VoIP, bandwidth allocation for interactive applications, and best-effort for bulk transfers.

A network administrator is troubleshooting a WAN link that carries VoIP and data traffic. Users report intermittent voice quality issues. The administrator checks the link and sees that utilization is 60%, but the voice quality issues occur even when utilization is 30%. The administrator suspects jitter. Which monitoring approach would best confirm the root cause?

Monitor the number of packets dropped by the router's queue.

Monitor the average link utilization over a 24-hour period.

Monitor jitter on the WAN link using active probes that measure packet delay variation over time.

Monitor the TCP retransmission rate.

Part of the Campus and Branch WAN Design domain, which makes up ~33% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~12–20 in this domain), expect 1–2 from this objective — we provide 30 practice questions to prepare you well beyond it.
