单选题 Refer to the exhibit.What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown?()
The Seria l0/0interface is passing traffic.
The DLCI 100 was dynamic allyallocated by the router
The Seria l0/0 interf aceacquired the IP address of 172.16.3.1 from a DHCP server
The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud
The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP
单选题 You are deploying two core switches,one in each building,50 km away from each other. The cross-connection between them will be a Layer 2 2-gigabit EtherChannel with an 802.1Q trunk. You configured it correctly but the link does not come up. The port is in the "admin up" state,and the line protocol is in the "down" state. The fiber link is OK. What would be the most likely reason for the link not to come up?()
The switches are not the same model.
You are not using the correct SFP.
You are not using correct optical media converters.
Configuration should be modified, because the distance is longer.
多选题 Which two of these are differences between traffic policing and traffic shaping?()
with traffic shaping,a router stores excess traffic in packet buffers until bandwidth is available again
with policing you can tune the buffer usage for traffic exceeding the specified CIR
with shaping you can tune the buffer usage for traffic exceeding the specified CIR
shaping should only be applied for ingress traffic,policing only for egress
policing uses a token bucket algorithm,shaping uses an SPD algorithm
