The correct answer is D. Bandwidth limit on the traffic shaper for the warehouse department. The traffic shaper limits the warehouse network to only 75 Mbps, which becomes a bottleneck during month-end periods when warehouse users generate heavy cloud application traffic.
Question
Warehouse users are reporting performance issues at the end of each month when trying to access cloud applications to complete their end of the month financial reports. They have no problem accessing those applications at the beginning of the month. Network information:

Why each option
The traffic shaper limits the warehouse network to only 75 Mbps, which becomes a bottleneck during month-end periods when warehouse users generate heavy cloud application traffic.
The finance department is allocated 230 Mbps - one of the highest limits in the configuration - which would not explain performance problems experienced specifically by the warehouse users.
No proxy server is referenced in the provided network information, and the issue is directly correlated with a bandwidth constraint that only manifests during high-volume periods, not application-layer filtering.
The internal firewall rules shown do not include a deny statement targeting the warehouse network (192.168.6.0/24), and the external firewall permits all networks to access the Internet, meaning the traffic is allowed.
The traffic shaper configuration assigns the warehouse network (192.168.6.0/24) a bandwidth cap of only 75 Mbps - the second-lowest allocation after the Guest network at 50 Mbps. During month-end financial reporting, warehouse users generate significantly more cloud application traffic simultaneously, and the 75 Mbps cap creates congestion that degrades application performance. Increasing the warehouse bandwidth allocation in the traffic shaper would resolve the recurring end-of-month performance issue.
