  channel-protocol lacp
  switchport trunk allowed vlans 1-10
• B. switchport mode trunk
  switchport trunk allowed vlans 1-10
  switchport trunk native vlan 11
• C. switchport mode trunk
  switchport trunk encapsulation dot1q
  switchport trunk allowed vlans 1-10
• D. switchport mode dynamic desirable
  channel-group 1 mode desirable
  switchport trunk encapsulation isl
  switchport trunk allowed vlan except 11-4094

Question #196 Topic 1

Two switches are connected and using Cisco Dynamic Trunking Protocol. SW1 is set to Dynamic Auto and SW2 is set to Dynamic Desirable. What is the result of this configuration?

• A. The link becomes an access port.
• B. The link is in an error disabled state.
• C. The link is in a down state.
• D. The link becomes a trunk port.

Question #241 Topic 1

An engineer requires a switch interface to actively attempt to establish a trunk link with a neighbor switch. What command must be configured?

• A. switchport mode trunk
• B. switchport mode dynamic desirable
• C. switchport nonegotiate
• D. switchport mode dynamic auto

Question #243 Topic 1

An engineer must establish a trunk link between two switches. The neighboring switch is set to trunk or desirable mode. What action should be taken?

• A. configure switchport nonegotiate
• B. configure switchport mode dynamic desirable
• C. configure switchport mode dynamic auto
• D. configure switchport trunk dynamic desirable

Question #247 Topic 1

Refer to the exhibit. Which command must be executed for Gi1/1 on SW1 to passively become a trunk port if Gi1/1 on SW2 is configured in desirable or trunk mode?

• A. switchport mode dynamic auto
• B. switchport mode dot1-tunnel
• C. switchport mode dynamic desirable
• D. switchport mode trunk

Question #255 Topic 1

An engineer must configure traffic for a VLAN that is untagged by the switch as it crosses a trunk link. Which command should be used?

• A. switchport trunk encapsulation dot1q
• B. switchport trunk allowed vlan 10
• C. switchport mode trunk
• D. switchport trunk native vlan 10

Question #266 Topic 1

Refer to the exhibit. Which action do the switches take on the trunk link?

• A. The trunk does not form, and the ports go into an err-disabled status.
• B. The trunk forms, but the mismatched native VLANs are merged into a single broadcast domain.
• C. The trunk forms, but VLAN 99 and VLAN 999 are in a shutdown state.
• D. The trunk does not form, but VLAN 99 and VLAN 999 are allowed to traverse the link.

Question #270 Topic 1

Refer to the exhibit. An engineer is asked to insert the new VLAN into the existing trunk without modifying anything previously configured. Which command accomplishes this task?

• A. switchport trunk allowed vlan 100-104
• B. switchport trunk allowed vlan 104
• C. switchport trunk allowed vlan all
• D. switchport trunk allowed vlan add 104

Question #691 Topic 1

What is the default port-security behavior on a trunk link?

A. It places the port in the err-disabled state if it learns more than one MAC address.

B. It causes a network loop when a violation occurs.

C. It disables the native VLAN configuration as soon as port security is enabled.

D. It places the port in the err-disabled state after 10 MAC addresses are statically configured.

Question #1204 Topic 1

Refer to the exhibit. An administrator must connect SW_1 and the printer to the network. SW_2 requires DTP to be used for the connection to SW_1. The printer is configured as an access port with VLAN 5. Which set of commands completes the connectivity?

A. switchport mode dynamic auto

switchport private-vlan association host 5

B. switchport mode trunk

switchport trunk pruning vlan add 5

C. switchport mode dynamic desirable

switchport trunk allowed vlan add 5

D. switchport mode dynamic auto

switchport trunk encapsulation negotiate

Question #206 Topic 1

In a CDP environment, what happens when the CDP interface on an adjacent device is configured without an IP address?

A. CDP becomes inoperable on that neighbor

B. CDP uses the IP address of another interface for that neighbor

C. CDP operates normally, but it cannot provide IP address information for that neighbor

D. CDP operates normally, but it cannot provide any information for that neighbor

Question #279 Topic 1

Refer to the exhibit. An engineer is configuring a Layer 3 port-channel interface with LACP. The configuration on the first device is complete, and it is verified that both interfaces have registered the neighbor device in the CDP table. Which task on the neighbor device enables the new port channel to come up without negotiating the channel?

A. Configure the IP address of the neighboring device.

B. Bring up the neighboring interfaces using the no shutdown command.

C. Change the EtherChannel mode on the neighboring interfaces to auto.

D. Modify the static EtherChannel configuration of the device to passive mode.

Question #194 Topic 1

Refer to the exhibit. How does SW2 interact with other switches in this VTP domain?

A. It transmits and processes VTP updates from any VTP clients on the network on its trunk ports.

B. It processes VTP updates from any VTP clients on the network on its access ports.

C. It receives updates from all VTP servers and forwards all locally configured VLANs out all trunk ports.

D. It forwards only the VTP advertisements that it receives on its trunk ports.

Question #216 Topic 1
