Refer to the exhibit. An engineer ts building a new Layer 2 LACP EtherChannel between SW1 and SW2, and they executed the given show commands to verify the work. Which additional task must be performed so that the switches successfully bundle the second member in the LACP port-channel?
- A. Configure the switchport trunk allowed vlan 300 command on SW1 port-channel 1.
- B. Configure the switchport trunk allowed vlan add 300 command on interface Fa0/2 on SW2.
- C. Configure the switchport trunk allowed vlan add 300 command on SW1 port-channel 1.
- D. Configure the switchport trunk allowed vlan 300 command on interface Fa0/2 on SW1.
When the LAG configuration is updated on a Cisco WLC, which additional task must be performed when changes are complete?
- A. Reboot the WLC.
- B. Flush all MAC addresses from the WLC.
- C. Re-enable the WLC interfaces.
- D. Re-associate the WLC with the access point.
Question 1413
When a switch receives a frame from an unknown source MAC address, which action does the switch take with the frame?
- A. It sends the frame to ports within the CAM table identified with an unknown source MAC address.
- B. It floods the frame out all interfaces, including the interface it was received on.
- C. It associates the source MAC address with the LAN port on which it was received and saves it to the MAC address table.
- D. It attempts to send the frame back to the source to ensure that the source MAC address is still available for transmissions.
What is the root port in STP?
- A. It is the port with the highest priority toward the root bridge.
- B. It is the port on the root switch that leads to the designated port on another switch.
- C. It is the port that is elected only when the root bridge has precisely one port on a single LAN segment.
- D. It is the port on a switch with the lowest cost to reach the root bridge.
What are two features of PortFast? (Choose two.)
- A. Convergence is fast after a link failure.
- B. STP loops are mitigated for uplinks to other switches.
- C. Ports transition directly from the blocking state to the forwarding state.
- D. Ports operate normally without receiving BPDUs.
- E. Ports that connect to the backbone automatically detect indirect link failures.
DRAG DROP
–
Drag and drop the VLAN port modes from the left onto the descriptions on the right.
Which EtherChannel mode must be configured when using LAG on a WLC?
- A. on
- B. passive
- C. active
- D. auto
Refer to the exhibit. Rapid PVST+ mode is on the same VLAN on each switch. Which switch becomes the root bridge and why?
- A. SW4, because its priority is highest and its MAC address is lower
- B. SW1, because its priority is the lowest and its MAC address is higher
- C. SW2, because its MAC address is the highest
- D. SW3, because its priority is the highest
A switch is forwarding a frame out of all interfaces except the interface that received the frame. What is the technical term for this process?
- A. ARP
- B. CDP
- C. flooding
- D. multicast
Which port state processes BPDUs, but does not forward packets or update the address database in Rapid PVST+?
- A. blocking
- B. learning
- C. listening
- D. disabled
