How does the dynamically-learned MAC address feature function?

A. The CAM table is empty until ingress traffic arrives at each port

B. Switches dynamically learn MAC addresses of each connecting CAM table.

C. The ports are restricted and learn up to a maximum of 10 dynamically-learned addresses

D. It requires a minimum number of secure MAC addresses to be filled dynamically

What are two characteristics of a controller-based network? (Choose two)

A. The administrator can make configuration updates from the CLI

B. It uses northbound and southbound APIs to communicate between architectural layers

C. It moves the control plane to a central point.

D. It decentralizes the control plane, which allows each device to make its own forwarding decisions

Refer to the exhibit. An engineer must add a subnet for a new office that will add 20 users to the network. Which IPv4 network and subnet mask combination does the engineer assign to minimize wasting addresses?

A. 10.10.225.48 255.255.255.240

B. 10.10.225.32 255.255.255.240

Refer to the exhibit.

What is the effect of this configuration?<

A. All ARP packets are dropped by the switch

B. Egress traffic is passed only if the destination is a DHCP server.

C. All ingress and egress traffic is dropped because the interface is untrusted

D. The switch discard all ingress ARP traffic with invalid MAC-to-IP address bindings.

Which action is taken by a switch port enabled for PoE power classification override?

A. When a powered device begins drawing power from a PoE switch port a syslog message is generated

B. As power usage on a PoE switch port is checked data flow to the connected device is temporarily paused

C. If a switch determines that a device is using less than the minimum configured power it assumes the device has failed and disconnects

D. Should a monitored port exceeds the maximum administrative value for power, the port is shutdown and err-disabled

Refer to the exhibit.

How does CAPWAP communicate between an access point in local mode and a WLC?

A. The access point must directly connect to the WLC using a copper cable

B. The access point must not be connected to the wired network, as it would create a loop
