CAS-003 Question #209: Real Exam Question with Answer & Explanation

The correct answer is D: Bandwidth limit on the traffic shaper for the warehouse department. The warehouse network (192.168.6.0/24) is limited to only 75 Mbps on the traffic shaper, compared to the finance department's 230 Mbps. At month-end, warehouse users attempt to access cloud applications to complete financial reports - an unusually high-bandwidth activity that the

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.

Options

  • ABandwidth limit on the traffic shaper for the finance department
  • BProxy server preventing the warehouse from accessing cloud applications
  • CDeny statements in the firewall for the warehouse network
  • DBandwidth limit on the traffic shaper for the warehouse department

Explanation

The warehouse network (192.168.6.0/24) is limited to only 75 Mbps on the traffic shaper, compared to the finance department's 230 Mbps. At month-end, warehouse users attempt to access cloud applications to complete financial reports - an unusually high-bandwidth activity that they don't perform at the beginning of the month. The 75 Mbps cap is insufficient to handle this surge in demand, causing performance degradation. Option A (finance bandwidth limit) is irrelevant since the finance department has 230 Mbps and is not reported as having issues. Option B (proxy blocking) would cause complete failure, not intermittent slowness. Option C (firewall deny rules) would also cause full connectivity failure, not just performance issues at specific times.
