Performance Routing PfR
Question 1
Refer to the exhibit.
Which statement is true?
A. The Cisco PfR state is UP; however, the external interface Et0/1 of border router 10.1.1.1 has exceeded the maximum available bandwidth threshold.
B. The Cisco PfR state is UP; however, an issue is preventing the border router from establishing a TCP session to the master controller.
C. The Cisco PfR state is UP and is able to monitor traffic flows; however, MD5 authentication has not been successful between the master controller and the border routers.
D. The Cisco PfR State is UP; however, the receive capacity was not configured for inbound traffic.
E. The Cisco PfR state is UP, and the link utilization out-of-policy threshold is set to 90 percent for traffic exiting the external links.
B. The Cisco PfR state is UP; however, an issue is preventing the border router from establishing a TCP session to the master controller.
