Two switches are connected with four links configured as an EtherChannel using LACP. The channel is up and passing traffic, but the load is not evenly distributed. The engineer wants to change the load-balancing method to better distribute traffic. Which command should be used?

`port-channel load-balance src-dst-ip`

`interface port-channel 1` then `load-balance src-dst-ip`

Which DTP mode combination will result in a trunk being formed between two Cisco switches?

dynamic desirable on one switch and dynamic auto on the other

trunk on one switch and access on the other

A security administrator is hardening access ports on a switch. They want to prevent a user from connecting a rogue switch to an access port and forming a trunk to gain access to other VLANs. Which configuration should be applied to the access ports?

`switchport mode trunk` and `switchport nonegotiate`

`switchport mode access` and `switchport nonegotiate`

`switchport mode dynamic desirable`

`switchport mode dynamic auto` and `switchport nonegotiate`

An administrator is troubleshooting a trunk between two switches. The trunk is up, but VLAN 10 traffic is not crossing. `show interfaces trunk` on Switch A lists VLAN 10 as active on the trunk, but `show interfaces trunk` on Switch B does not list VLAN 10. What is the most likely cause?

VLAN 10 is not created on Switch B.

The encapsulation on Switch B is set to ISL.

The native VLAN is mismatched on the two switches.

The `switchport trunk allowed vlan` list on Switch A is missing VLAN 10.
