Question

Since installing a cisco TelePresence system, the company is experiencing other application having response issues when the system in use. As a result, the company asked an architect to recommend a QoS solution. The customer is currently using a CBWFQ policy to manage traffic on an internet connection with a speed of 100 Mbps. Which link-capacity limit must the architect choose for strict-priority for the real-time traffic?

Options

  • A25 Mbps
  • B50 Mbps
  • C33 Mbps
  • D75 Mbps

Explanation

Cisco Technical Marketing testing has shown a significant decrease in data application response times when real-time traffic exceeds one-third of a link's bandwidth capacity. Extensive testing and customer deployments have shown that a general best queuing practice is to limit the amount of strict-priority queuing to 33 percent of a link's capacity. This strict-priority queuing rule is a conservative and safe design ratio for merging real-time applications with data applications.
