Switching Concepts Quiz

What information is added to the switch table from incoming frames?

• source MAC address and incoming port number

• destination MAC address and incoming port number

• source IP address and incoming port number

• destination IP address and incoming port number

Which switching method ensures that the incoming frame is error-free before forwarding?

• cut-through

• FCS

• fragment free

• store-and-forward

Refer to the exhibit. How many broadcast domains are displayed?

• 1

• 4

• 8

• 16

• 55

Under which two occasions should an administrator disable DTP while managing a local area network? (Choose two.)

• when connecting a Cisco switch to a non-Cisco switch.

• when a neighbor switch uses a DTP mode of dynamic auto

• when a neighbor switch uses a DTP mode of dynamic desirable

• on links that should not be trunking.

• on links that should dynamically attempt trunking

Which two characteristics describe the native VLAN? (Choose two.)

• Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN.

• The native VLAN traffic will be untagged across the trunk link.

• This VLAN is necessary for remote management of a switch.

• High priority traffic, such as voice traffic, uses the native VLAN.

• The native VLAN provides a common identifier to both ends of a trunk.

On a switch that is configured with multiple VLANs, which command will remove only VLAN 100 from the switch?

• Switch# delete flash:vlan.dat

• Switch(config-if)# no switchport access vlan 100

• Switch(config-if)# no switchport trunk allowed vlan 100

• Switch(config)# no vlan 100.

Refer to the exhibit. A network administrator is reviewing port and VLAN assignments on switch S2 and notices that interfaces Gi0/1 and Gi0/2 are not included in the output. Why would the interfaces be missing from the output?

• There is a native VLAN mismatch between the switches.

• There is no media connected to the interfaces.

• They are administratively shut down.

• They are configured as trunk interfaces.

A network contains multiple VLANs spanning multiple switches. What happens when a device in VLAN 20 sends a broadcast Ethernet frame?

• All devices in all VLANs see the frame.

• Devices in VLAN 20 and the management VLAN see the frame.

• Only devices in VLAN 20 see the frame.

• Only devices that are connected to the local switch see the frame.

Refer to the exhibit. All workstations are configured correctly in VLAN 20. Workstations that are connected to switch SW1 are not able to send traffic to workstations on SW2. What could be done to remedy the problem?

• Allow VLAN 20 on the trunk link.

• Enable DTP on both ends of the trunk.

• Configure all workstations on SW1 to be part of the default VLAN.

• Configure all workstations on SW2 to be part of the native VLAN.

What happens to switch ports after the VLAN to which they are assigned is deleted?

• The ports are disabled.

• The ports are placed in trunk mode.

• The ports are assigned to VLAN1, the default VLAN.

• The ports stop communicating with the attached devices.
