An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the the switches are not negotiating a trunk. What is a probable cause for this issue?

Both switches are in trunk mode.

Both switches are in nonegotiate mode.

Switches from other vendors do not support DTP.

DTP frames are flooding the entire network.

In which location are the normal range VLANs stored on a Cisco switch by default?

flash memory

startup-config

running-config

RAM

Refer to the exhibit. What protocol should be configured on SW-A FastEthernet 0/1 if it is to send traffic from multiple VLANs to switch SW-B?

If an organization is changing to include Cisco IP phones in its network, what design feature must be considered to ensure voice quality?

Voice traffic needs to be tagged with the native VLAN.

A separate VLAN is needed for voice traffic.

Additional switch ports that are dedicated to Cisco IP phones are required.

Voice traffic and data traffic require separate trunk links between switches.

Which step should be performed first when deleting a VLAN that has member switch ports?

Reload the switch.

Implement the command delete vlan.dat.

Reassign all VLAN member ports to a different VLAN.

Backup the running-config.

Which distinct type of VLAN is used by an administrator to access and configure a switch?

default VLAN

native VLAN

Data VLAN

management VLAN

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 is one way to prevent the VLAN hopping attack?

Disable DTP negotiation on all ports.

Change the native VLAN to an unused VLAN.

Designate a different default VLAN.

Remove all user VLANs from the trunk.

What is the purpose of the switch command switchport access vlan 99?

To enable port security

to make the port operational

to assign the port to a particular VLAN

to designate the VLAN that does not get tagged

to assign the port to the default native VLAN (VLAN 99)

Which two statements describe the benefits of VLANs? (Choose two.)

VLANs improve network performance by regulating flow control and window size.

VLANs enable switches to route packets to remote networks via VLAN ID filtering.

VLANs reduce network cost by reducing the number of physical ports required on switches.

VLANs improve network security by isolating users that have access to sensitive data and applications.

VLANs divide a network into smaller logical networks, resulting in lower susceptibility to broadcast storms.

Which two statements accurately describe DTP? (Choose two.)

DTP is a Cisco proprietary protocol.

DTP supports IEEE 802.1Q.

Cisco switches require DTP to establish trunks.

DTP must be enabled on only one side of the trunk link.

Trunk ports that are configured for dynamic auto will request to enter the trunking state.

A switch receives a frame on a trunk port, but the frame is tagged with the same VLAN ID as the native VLAN of the trunk link. What happens to that frame?

The frame is broadcast.

The frame is flooded.

The frame is forwarded.

The frame is dropped.

For what reason would a network administrator use the show interfaces trunk command on a switch?

to view the native VLAN

To examine DTP negotiation as it occurs

to verify port association with a particular VLAN

to display an IP address for any existing VLAN
